水力喷射射孔技术是一种新的油层改造技术,该技术利用高压射流的水力破岩作用,在油层中定向钻出直径30mm-50mm、长度可达50m-100m的定向孔眼,通过增大油层内的泄流面积来提高油井产量。本文以DQ3-P2288井为例对水力喷射水平打孔改造技术的工艺原理、孔眼轨迹设计原则及轨迹确定进行了探讨。试验结果表明该技术可有效提高油井产量,为高含水期油田进一步改造增产提供一定的指导意义。
Hydraulic jet perforation technology is a new oil layer reconstruction technology that utilizes the hydraulic rock breaking of high pressure jet to directional drill directional holes with the diameter of 30mm-50mm and the length of 50m-100m in the oil layer. By increasing the oil layer Discharge area within to improve well production. This paper takes DQ3-P2288 well as an example to discuss the technological principle, the principle of trajectory design and the trajectory determination of hydraulic drilling horizontal drilling technology. The test results show that the technology can effectively improve the production of oil wells and provide some guidance for the further reform and production increase of high-water cut oil fields.
