摘要
电脉冲增注技术是一种物理法增注新技术,它以脉冲冲击压力和点作业方式为最主要特点而有别于传统的增注措施。从电脉冲增注技术原理入手,针对低渗透油藏的特点将电脉冲装置改进成小电容高电压电脉冲装置,结合前期试验总结,初步提出低渗透油藏的选井选层条件,采用电脉冲、电脉冲+酸洗两种不同工艺及作业参数,在长庆油田低渗透油藏长X、长Y油层组开展现场试验;通过试验效果跟踪及分析,形成了低渗透油藏长X、长Y油层组的一种电脉冲增注工艺技术。
Electric pulse augmented injection technique,which was different from traditional measure of augmented injection,was a new technology using physical method,it took the pulse pressure impact and operation mode as the main characteristics.Starting from the principle of the increase of the electric pulse injection technology,the electrical pulse device was improved into a small capacitance and high voltage electrical pulse device according to the characteristics of low permeability reservoirs.Combined with the previous test summary,the condition for well choosing of low permeability reservoirs is initially proposed,different techniques and operation parameters of electric pulse,electric pulse+ acid clean are used for field test in low permeability reservoirs in Chang 4+5and Chang 6Reservoirs of Changqing Oilfield,by tracking and analzing test results,the technique of electric pulse augmented injection is established for low permeability reservoirs,such as Chang 4+5and Chang 6Reservoirs
