低压低产气井增压开采技术

摘要

According to the characteristics of gas reservoir,the pressure-boosting stimulation was optimized. The gas wells for pressure-boosting stimulation were selected based on pressure decline and producing reserve of gas-fields,and production,tubing pressure,and working conditions of gas wells;the skid-mounted,gas engine-driven,small-scale compressor was selected for the shallow gas reservoir;the reciprocating compressor was selected for the deep gas reservoir;Analysis shows good result of pressure-boosting stimulation.%针对气井低压低产、油压接近外输压力、气井出现水淹停产、登娄库组气藏部分气井低压的问题,提出气井增压开采措施.优化浅层气藏增压开采工艺和深层气藏增压开采工艺;根据气田压力递减规律、储量动用情况及气井产量、压力、井况等,优选增压开采气井;浅层气藏优选了橇装式、燃气发动机驱动的小型压缩机;深层气藏选择往复式压缩机.分析发现增压开采效果好.
