Characteristics of SICHUAN Basin

Sichuan Basin is the main operation area of RENZHI, we have provided drilling fluid technical services for

oil-gas fields in Sichuan Basin for many years, and we have been furnishing the technical services to most of

important wells and complex wells of Sinopec in Northeast Sichuan. Due to notoriously complicated and

extreme geographical & geological conditions of Sichuan Basin, most of the same technical problems as ever

occurred in the rest of world have arisen during the site drilling process.

High Salinity Sewage Desalination Technology

Renzhi has contributed great resources in studying and testing several technologies in

oilfield industry and extracted low-temperature multi-effect distillation technology as the

feasible technology of high salinity sewage desalination for further promotion in

petrochemical industry from membrane process and thermal distillation , etc.

In 2011, Southwest branch of Sinopec applied our research achievement and

constructed harmless treatment plant for high chloride sewage at West Sichuan Gas

Field. Up to now, it has worked in good condition and the water discharged can meet the

strict national standard, which wins acceptance from all walks.
