Description
技术领域technical field
本实用新型涉及煤层气排采领域，尤其涉及一种煤层气井无动力气液自然分离装置。The utility model relates to the field of coal bed gas extraction and production, in particular to a non-powered gas-liquid natural separation device for coal bed gas wells.
背景技术Background technique
煤层气井排水采气时，在泵筒的抽吸作用下，气液混合物中的部分煤层气未能从排采的液体中有效脱附，致使其通过油管从地面排水口排出、形成窜气，这一问题在“L”形水平井中尤为突出。煤层气和排采的液体不能有效分离，既降低了煤层气的生产，同时造成了一定的环境污染及安全隐患，严重时可导致爆炸等安全事故、无法正常生产。When coalbed methane wells are drained to produce gas, under the suction of the pump barrel, part of the coalbed methane in the gas-liquid mixture cannot be effectively desorbed from the drained liquid, causing it to be discharged from the surface drain through the oil pipe to form blow-by gas. This problem is particularly prominent in "L" shaped horizontal wells. Coalbed methane and drained liquid cannot be effectively separated, which not only reduces the production of coalbed methane, but also causes certain environmental pollution and safety hazards. In severe cases, it may lead to safety accidents such as explosions and failure of normal production.
