Sustainable Strategy for Gas Supply in China: Based on Foam Drainage Gas Recovery Technology

With the increasing demand of natural gas in China, its production is extremely important to fulfill requirement society. However, reality, from well field often accompanied by formation water. For with low production, flow rate too carry out water bottom well. The will thus accumulate bore and be greatly diminished. To solve this problem, based on developing status M foaming surfactant Z301 synthesized then agent ZK3012 developed through combination CAT after optimization experiments. After that, compatibility tests are conducted ensure that can work together fluids, carrying concerning optimum concentration ZK3012. Finally, pilot test 2 wells site field, good results obtained accumulated discharged foam drainage increased. Studies demonstrate main steps involved for application technology. In regard high external dependence degree China supply, operators fields should give prominence related studies technology achieve sustainable development.
