摘要
低孔、低渗储层深井排液工艺是低孔、低渗试油气工艺技术的重要环节。通过2年多的生产实践,酸化—气举排液一体化管柱工艺技术和水力射流泵排液技术在各类探井中已得到广泛应用。从应用效果分析,该技术有效增加了排液深度,减少了对地层的伤害,缩短了试油周期。
Technology of flowing back in deep well in low porosity and permeability reservoir is the important link during oil and gas production testing in low porosity and permeability reservoir.By field practice for two years,technologies have been widely used in all kinds of exploration wells,which one is unitization string of acidizing,gas lifting and flowing back,another one is flowing back with hydraulic jet pump.Analyzing from application effect,this tech effectively adds depth to flowing back,and reduces harm to formation,and shorts period to oil production test.
