正理庄油田樊142沙三下特低渗透油藏储量丰度低,常规开发难度大,经济效益差,针对该油藏特点我们进行了四项关键核心技术研究,分别进行了“仿水平井”开发适应性评价,油藏地应力分布描述技术研究,油藏方面进行井网优化设计,工艺技术方面进行定向控制、逢长控制和缝高控制。从该技术现场方案实施后,沙三下难动储量最终得以高效开发,从压裂监测的缝长、产量等关键指标均达到了方案设计要求。
According to the characteristics of the reservoir, we conducted four key core technologies research, respectively, carried out “imitation horizontal well ”Development of adaptability evaluation, reservoir stress distribution description of technical research, reservoir optimization of well pattern design, process technology for directional control, every long control and seam height control. After the implementation of the technical site program, the reserves in the third three years were finally developed in an efficient manner. The key indicators such as seam length and yield of fracturing met the program design requirements.
