General Description

During drilling operations, various dynamic impact loads are impartedfrom the drill bit to the drill string. These loads, which are cyclical innature, may lead to many problems:

Premature failure of the drill string and rig equipment

Low penetration rates

Hole problems

The HYDRA-SHOCK Model B tool is designed to absorb and dampen

the variable axial dynamic loads produced by a drill bit during normaldrilling operations. Unlike other tools on the market, the HYDRA-SHOCK Model B tool is fully compensated for both pump pressure,which has a tendency to open the tool, and hydrostatic pressure, which hasa tendency to close the tool. Consequently, as dynamic impact loads aretransferred from the bit to the drill string, the tool, which is in a hydrauli-cally neutral position, readily dampens the loads without the additionaltask of overcoming any pressure differentials. Additionally, the toolsstroke length and low spring rate make it active over a much greater rangeof operation. As a result, the penetration rate and bit life are greatly im-proved.

As axial loads are produced, energy absorption is accomplished throughthe use of a spring element; force dampening is accomplished through theuse of fluid and mechanical friction; and pressure compensation is accom-plished through the use of a fluid transfer system. These three elements arethe heart of the tool.

Operation

As a tri-cone bit rotates, it produces a pattern on the bottom of the bore-hole which consists of peaks and valleys. With each revolution of thebit, the cones will tend to follow the sinusoidal contour of the bottom of

the borehole producing a cyclical oscillation of the drill string. Thesprings in the HYDRA-SHOCK Model B tool, normally used to keepthe tool extended, are compressed and absorb the shock load produced bythe bit cones as they progress through one of the peaks.

Additionally, the load is dissipated by fluid friction created when oil ismetered through the spring stack and by mechanical friction resulting fromthe movement of the spring stack. When the bit cones move into a val-ley, the HYDRA-SHOCK Model B tools springs will extend the toolto its normal position. These two combined actions isolate the axial loadspresent during the drilling operation and maintain a near constant weight-on-bit when the tool is run within its operational load limits.

Maximum shock absorption is achieved by placing the HYDRA-SHOCKModel B tool as close to the bit as possible. Care should be taken to en-sure that the tool is never run in the neutral zone, in tension, or in over-sized boreholes (hole sizes greater than 2 times the OD of the tool).

The engineering specifications for the HYDRA-SHOCK Model B tool canbe found in Table 1.

Placement

The HYDRA-SHOCK Model B Tool is most effective when placed di-rectly above the bit. Like other vibration dampeners, the HYDRA-SHOCK Model B tool is less stiff than a drill collar of the same OD.

Depending on the placement of the tool, the reduced stiffness can compro-mise the performance of the bottom hole assembly. Also, if improperlyplaced in the bottom hole assembly, high stresses could reduce tool per-formance and life. General guidelines for tool placement are as follows:

In a slick bottom hole assembly, place the tool above the bit, as

shown in FIG. 1.

For a pendulum assembly used in very mild crooked tendencies,

the tool can be placed directly above the bit, as shown in FIG. 2.

For pendulum assemblies used where there are crooked hole ten-

dencies, it is recommended that the tool be placed directly abovethe first (fulcrum) stabilizer, as shown in FIG. 3. In addition, a sec-

ond stabilizer should be placed one drill collar up from the tool.

This will help reduce stresses in the tool due to lateral loads.

In packed bottom hole assemblies, it is recommended that the tool

be placed above the second zone of stabilization, as shown in FIG.

4. Avoid using the tool as a short drill collar since the reduced stiff-

ness will compromise bottom hole assembly performance and in-

crease bending stresses in the tool.

When crooked hole tendencies are severe, it is recommended that

the tool be placed above the third zone of stabilization, as shown inFIG. 5. It is also recommended that an additional stabilizer be

placed one drill collar above tool to reduce lateral loading.

Thread Galling Cautions

Galling can be caused by:

Dirty or damaged threads and/or thread shoulders.

Threads and shoulders that are not completely covered with thread

lubricant before assembly.

Misaligned connections during assembly or disassembly.

Applying a bending load when torquing the connection duringassem-

bly or disassembly.

Leakage which would allow the connection to become dry or filled

with abrasive matter.

Steps to prevent galling:

Clean and dry connection threads and shoulders thoroughly.

Apply thread lubricant evenly over threads and shoulders.

Position the backup device and breakout device as shown in disas-

sembly and assembly sections.

Support and tie down the appropriate parts with a hold down steady

rest as described in Disassembly and Assembly.

Torque connection properly, to the recommended make-up torque.

To Break A Stuck Connection

Tap the outside surface of the connection with a hammer while slowly un-

screwing the part. It may be helpful to work the connection out by alternatelytightening and untightening the part several times, FIG. 7.

If such methods fail, one part of the connection can sometimes be ma-chined away in an attempt to salvage the other.

Ultimately, the connection can be forced apart. This may scrap both parts.

Inspection Procedures

Inspection should occur as soon as possible after tool is used. Replace partswhich do not comply to an acceptable condition. No machining or rework-ing is to be performed without Smith ServicesHE Group's approval.

Incoming Inspection

Visually inspect for damage to the external members and note ab-

normal wear or markings.

Check for Hydrogen Sulfide residue with Lead Acetate Tape.

Place tape strips at all ports and vents were the tape can come in

contact with the well fluids left in the tool. If a positive indication isnoted, special treatment of the part is required.

Cleaning

1. Water soak tool parts to remove dried, caked mud.

2. Use steam and a strong biodegradable cleaner to remove oil and grease.

3. Allow steam cleaned parts to dry and cool before inspecting tool.


Inspect all parts, using the steps below, each time the tool is disassembled.

Inspect all rotary shouldered connections per API. Inspection pro-cedures will meet the applicable contentof API RP 7G, Section 12.

Inspect all make up shoulders and faces for galling and wash. Re-

pair or replace part as needed.

Use the Part Inspection Guideline for individual parts. Repair or

replace part if condition noted in guideline exist.

Use Magnetic Particle Inspection Guidelines for Magnetic Parti-

cle Inspection of parts.

Check all external parts for wear down. Replace part when the OD

wear is at or below the diameters listed in Table 5.

Heavy grooves or junk cuts that exceed minimum wear down are

not acceptable.

Multiple grooves or cuts are in a small area are not acceptable.

Use Critical Parts Inspection form to record part condition, part

diameters, and results from magnetic particle inspection.



30/68

Use Fishing Dimensions for length, ID, and OD comparison. Re-

cord findings on Critical Length Tolerance form.

Use Chrome Guidelines to inspect chrome.

Magnetic Particle Inspection Guideline

Refer to API RP 7G for guidelines. Subject critical stress areas to Mag-netic Particle Inspection at each service. Replace parts if indication isfound and cannot be removed by acceptable practice.

A characteristic of industrial hard chrome is micro cracking. Micro crack-ing does not pose a problem or threat of failure to the part. Typical microcracking should not constitute criteria for rejecting a part.

Critical Stress Areas

Pin connections plus 1" (25 mm) beyond the shoulder or end of the

thread.

External component box connections (inside and outside) plus1" (25 mm) beyond the connection.

Internal component box connections (inside and outside) and all

grooves up to the end of the last groove or end of the relief or

make-up face.

Fill plug holes, service plug holes, ports, vents, slots, and

2" (51 mm) either side.

Large diameter changes plus 4" (102 mm) either side.

Chrome Guidelines

Record condition of chrome area on Critical Parts Inspection form. Thefollowing guidelines may be tempered based on knowledge and experi-ence for a given area and environment tools will be utilized.

Hydraulic Fluid Seal Area

Pits in chrome

The maximum acceptable pit diameter is 1/8" (3 mm).

The maximum acceptable pit depth is 1/64" (0.5 mm).

Multiple pits must be at least 3/8" (10 mm) apart.

A maximum of 3 pits ina 1" x 1" (25 mmx 25 mm)square area are

acceptable.

Chipped chrome

Missing or chipped chrome is not acceptable.

It is acceptable for chrome outside of the seal area to be pitted, missing, orchipped. Dress and remove sharp edges from these areas.




31/68


32/68

Springs

a. Twenty-five percent of the springs should be subjected to mag-

netic particle inspection (MPI). During the MPI, the coils should be

positioned such that the inspector can check for cracks propagating

circumferentially on the I.D. and O.D. surfaces as well as for cracks

propagating radially from the I.D. of the part towards the O.D. of thepart. If cracks or other improprieties are found in one (1) spring, all

springs in the spring stack shall be subjected to MPI testing.

b. Springs that have cracks or other improprieties should be discarded.

c. Measure 25% of the springs, to determine if there are any changes in

overall height. Height variations greater than those specified in Table

3 found in one (1) spring shall necessitate the measurement of all

springs.

Seal Assembly Procedures

Seal Description

The HE Group SUPER SEAL is a composite type of material with eachseal element performing a specific function.

The SNE Ring is forced down the gland taper to close the shaft to

gland clearance as pressure is applied to the Major Seal. Closure of

the SNE Ring prevents extrusion of the SSRRing and Major Seal.

The SSR, made of glass-filled Teflon, not only acts as a spacer be-

tween the Major Seal and SNE Ring, but polishes and conditions

the chrome and/or colmonoy shaft as it reciprocates under pres-

sure.

The Major Seal, the resilient seal member, must hold both low and

high pressure. The Major Seal is double-acting when a tapered seal

groove is provided as shown in the illustration below.

A Rod Wiper, positioned forward of the SUPER SEALS and PolyPak,prevents grease, mud and debris from entering.

Seal Inspection

Inspect all seals (O-rings, SNEs, SSRs, Major Seals, PolyPaks and RodWipers) after steam cleaning. If any seal appears worn or cracked, replaceit. Seal must be absolutely clean to reuse
