| 摘 要： | 介绍了暂堵压裂工艺在安塞油田坪北区的应用情况，针对塞油田坪北区低孔隙度、低渗透率储层油井压裂后产量下降较快的特点，以降低成本、提高油田开发经济效益为指导思想，进行了老井暂堵压裂改造现场试验。主要措施是运用暂堵剂封堵油井第一次压裂产生的人工裂缝，迫使人工裂缝转向，以便改善老井二次压裂改造的效果，提高油井产量。

| Abstract: | The authors introduce the application situations of temporary plugging and fracturing technology in Pingbei Area of Ansai Oilfield.They conduct site experiments to transform old oil wells by temporary plugging and fracturing,aiming at the characteristic about fracturing oil production quick decrease of the oil wells with low pores and low permeability and the guiding ideology for lowering cost and promoting the economic benefits of oilfield development.The main measures are to use temporary plugging agent to block man-made fracture as a result of the first fracturing so that the man-made fracture is forced to change direction,thus increasing the transforming results of the second fracturing in old oil wells. |
