At present, oil and gas exploration and development are making significant progress in areas such as ultra deep and unconventional formations. Drilling well control faces a series of safety challenges such as low prediction accuracy of spec...

How to obtain high viscosity slippery water with low dosage of drag reducing agents is currently an important development direction in the research and development of drag reducing agent technology. Aiming at the problems of poor thickening...

Shale oil and gas, tight oil and gas, and other unconventional oil and gas reservoirs generally use smooth hydraulic fracturing fluid for large-scale volume fracturing. Due to the low viscosity (less than 5 mPa·s), high filtration loss, and ...

At present, the continuous breakthroughs in technological bottlenecks such as high temperature and high pressure have driven the transformation of domestic oil and gas exploration and development towards high-quality development. How to eff...

With the development of exploration and development towards deep and ultra deep layers, complex geological environments such as high temperature (190 ℃), high pressure (143 MPa), high sulfur content (up to 450 g/m3), ultra-high pressure sal...
