摘要

延川南煤层气田经过数年的开发后

部分井已进入递减期

大部分井日产液量逐渐减少

面临间抽对产能和生产管理带来的影响

通过对煤层气渗流机理的研究

对于不同井况的低产液井采用无损智能间抽技术

综合考虑井下压力计、市电的峰谷电价、井下口袋的深度、远程启动抽油机安全风险等因素

在不影响气井稳产的情况下实施无人值守的间抽

减轻了排采井管理强度

提高了精细管理的效率

有一定的推广价值。

Abstract

After years of development

some wells in South Yanchuan coalbed methane field have entered the decline period

and the daily liquid production of most wells has gradually decreased. Therefore

it is about to face the impact of intermittent pumping on productivity and production management. By studying the seepage mechanism of CBM

the non-destructive intelligent intermittent pumping technology is adopted for low-yield liquid wells with different well conditions. Considering such factors as downhole pressure gauge

peak and valley electricity price of municipal electricity

depth of downhole pocket

safety risk of remote pumping unit and so on

the implementation of unattended intermittent pumping without affecting the stable production of gas wells reduces the intensity of drainage and production well management

improves the efficiency of fine management

and has higher popularization value.
