Amphiphilic oil polymers containing hydrophobic long-chain alkanes and hydrophilic polyether long-chain monomer structural units

The Bohai Sea has become one of the important bases for offshore oil and gas development in my country. The Bohai Oilfield accounts for about 70% of the total offshore oilfield production and is the largest offshore oilfield in my…

Water-locking agents: a key technological support for solving the water-locking problem in oil and gas extraction.

I. Water Locking: A “Hidden Obstacle” in Oil and Gas Extraction  During oil and gas field development, especially in the exploitation of low-permeability and ultra-low-permeability oil and gas reservoirs, as well as unconventional oil and gas resources such as shale gas…
