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...

In order to meet the development needs of different blocks and resource types, through continuous research and development, we have constructed high-temperature and large temperature difference cement slurry system, Ultra high temperature ...

Deep and ultra deep layers are important replacement areas for increasing oil and gas storage and production. After continuous technological breakthroughs, significant progress has been made in deep and ultra deep well cementing technology,...

In unconventional fields, hydraulic fracturing is a requirement, not an option. Whether the water used in fracking is recycled produced water or freshwater, it must be treated to remove bacteria to minimize equipment damage. One 100-barrel-...

For most of the Age of Oil, groups of producers have tried to control its price. From the 1920s, that strategy was co-ordinated by the Railroad Commission of Texas, supported by other US states and federal authorities. Then from the 1970s i...

Based on the new type of oil and gas reservoir, a new type of continuous differential casing sliding sleeve is used to determine the sliding sleeve and casing, and then implement conventional cementing, and then implement a series of hydrau...
