摘要: 页岩气田S区块，随着气藏开发深入，气井出现产量和压力双递减，气体携液能力逐渐下降，表现出不同程度井筒积液特征，严重制约气井连续生产。针对井筒积液问题，先后通过采取气举、泡排、柱塞、增压开采等排水采气工艺，均取得了不同程度增产效果。但各工艺措施适用条件及增产效果不一，因此有必要开展应用评价。
Abstract: In S block of the shale gas field, with the deep development of gas reservoirs, both the production and pressure of gas wells have gradually decreased, and the gas-carrying capacity has gradually decreased, showing different degrees of fluid accumulation in wellbore, which severely restricts the continuous production of gas wells. Aiming at the problem of fluid accumulation in the wellbore, drainage gas recovery technologies such as gas lift, bubble exhaust, plunger gas lift, and pressurized mining have been adopted to achieve varying degrees of production increase. However, the application conditions and production effects of various technological measures are different, so it is necessary to carry out application evaluation.
