摘要
针对油层常规(酸化、压裂等)大型增产措施经济成功率低的实际状况,开展了四种物理法(电脉冲、超声波、液态压裂、无电缆射孔)改造油层新技术,清除油气通道的污染和堵塞,改善油层渗透性能、降低原油粘度,达到油水井增产增注的目的。
In view of the actual situation thai the possibility of increasing oil production of oil layer by using conventional acidifying and compressive fracture is low, four new physical techniques, that is electric pulse, ultrasonic rive, liquid compressive fracture and non -cable perforating were developed. Using these techniques the pollution and blocking of oil/gas channel were eliminated, and penetrability of oil layers improved, and the viscosity of crude oil reduced with the increase of oil production and water injection.
