摘要
水力喷砂射孔分段压裂技术是将射孔、分层压裂融为一体的新型增产措施,无需下封隔器,一趟管柱即可完成多层段射孔压裂,提高了措施的有效性和安全性。通过实施该技术,可以避免常规射孔作业对地层的伤害,在一定程度上控制井筒附近裂缝起裂和延伸,与常规压裂技术相比有明显的优势。该技术成功应用于华北地区的水平井中,对提高油井的采收率有重大意义。
Tech of Hydraulic jet perforation and staged fracturing is a new measure to increase production integrated by perforation and separated layer fracturing,without using packer,and one testing string can realize perforating and fracturing operation to multilayer,improving the effectiveness and safety of the measure.Through the implementation of this technology,damage to the formation from the conventional perforating can be avoided,to a certain extent,initiation and extension of the fracture near wellbore are controlled,and the advantage compared with conventional fracturing technology is appeared obviously.It is successfully applied in the horizontal well in North China,has a great significance to improve the recovery rate of the oil well.
