A few days ago, borne by the Southern Institute of petrochemical projects " High performance industrial application of organic bentonite for drilling fluid " Through a research project organized by the China Ministry of science and technology review.
In order to adapt to China's shale gas exploration and development of unconventional oil and gas resources and solve encountered in the deep well drilling in complex strata of underground complex and frequent accidents, Southern Research Institute of China petrochemical oil-field drilling fluid technology and raw materials, laboratory research, test pilot and industrial applications, development NHY-1 Type organic bentonite for drilling fluids, forming a NHY-1 Industrial production of organic bentonite for drilling fluids, shale gas exploration and development of gas fields to Sinopec to provide products and services. Development of NHY-1 -type organic bentonite for drilling fluids, viscosity, dynamic shearing force, filtrate volume reaches 18.0mPa·s, and6.0Pa, and8mL, the performance is superior to domestic similar product, With similar foreign advanced product performance, reached the international advanced level. Completed a 50 ton NHY-1 -organic bentonite production, the product has excellent adhesion and high temperature resistance, high rate of slurry and the filtrate is low.
Through cooperation with the Zhongyuan oil field, completed 35 Wells in the commercial application of organic bentonite, test results show that: NHY-1 Type organic bentonite has good rheology, fluid loss and carrying capacity, for safe drilling, and drilling fluid additive has good compatibility, meets the shale oil and gas development and other non-conventional development of demand.
