四川气田气井多为有水气井,针对有水气井地质特征及机抽排水采气的特殊性,机抽工艺在配套设备及优化设计上作了许多重大改进。该工艺在四川气田纳1井经14年的推广应用,在选井、设计、施工和运行管理等方面总结出了一整套可行的经验,使该工艺获得了显著的增产成效,并成为一项行之有效的排水采气后续工艺。
Gas wells in Sichuan are mostly gas wells. Aiming at the geological characteristics of water vapor wells and the particularity of pumping and discharging gas, the pumping technology made many major improvements in equipment and optimization design. The process has been popularized and applied for 14 years in Well Nan 1 of gas field in Sichuan Province, and has put forward a set of feasible experiences in well selection, design, construction and operation management, etc., which has resulted in significant yield increase and become a Effective drainage of gas follow-up process.
