柱塞气举排水采气工艺在苏里格气田的应用研究

Research and using of gas lift plunger drainage gas in the Sulige gas field

柱塞气举排水采气工艺具有能够减少气体"滑脱"效应,增加间歇气举效率、单井增产效果显著等优点。柱塞气举工艺曾经在长庆气田的靖边气田少数单井上得到应用,取得一定效果。该工艺自去年以来在长庆气田的苏里格气田的部分气井上得到应用,使气井实现自动化启停,排水采气效果明显,柱塞气举工艺可进一步在苏里格气田推广使用。

Plunger gas-lifting dewatering gas process has advantages to reduce gas 'slippage' effect,increasing the efficiency of gas-lifting intermittent,yield of single well significant.Plunger gas-lifting technology has been applied on a few wells of Jingbian gas field in Changqing Gas Field,and achieved certain results.Since last year,The process has been applied on a small number of wells of Sulige gas field in Changqing gas field to gas wells automated start and stop,and the obvious effect of drainage gas,Plunger gas-lifting process can further promote the use of Sulige gas field.
