吉林油田大情字井探区射孔与压裂匹配技术可行性研究

Re-search on feasibility of perforating and fracturing matching technology in Daqingzi well exploration area of Jilin oilfield.

针对吉林油田大情字井探区压裂成功率低、压后产能低,压裂规模小等问题,进行了射孔与压裂匹配技术研究,分析了射孔孔密、孔径、射孔深度、方位等对压裂的影响,并通过室内论证和理论计算,给出了适合大情字井探区的射孔参数。

Aiming at the low successful ratio of fracturing, low productivity after fracturing and low fracture scale in Daqingzi well exploration area,the matching technology between perforating and fracturing is studied. The influence of perforating density, bore diameter, perforating depth and orientation on fracturing is analyzed. Through the demonstration indoor and theoretic calculation , the perforating parameters suitable to Daqingzi well exploration area are given.
