摘要
随着低渗油田压裂工艺的需要,提出了对裂缝监测结果准确性的要求,同时需要拓展监测结果的应用范围,总结了在鄂尔多斯盆地南部红河、渭北等5个油田进行的裂缝监测结果,对主要的几种裂缝监测技术的原理、优缺点以及裂缝监测的结果进行综合全面的分析以及对比,认为不同工艺的监测精度及监测参数的侧重点不同。对这些监测结果进行了验证,明确了每种监测技术所得参数的精度,去伪存真,综合利用裂缝监测所得的结果优化压裂参数,绘制井网,为避免裂缝窜通、下步重复压裂和注水井井位部署提供了参考依据。
This paper summarizes fracture monitoring results in five oil fields in the south of Erdos basin, a comprehensive analysis and comparison has being carried out between the main advantages and disadvantages in the principle of several fracture monitoring methods.The accuracy of different monitoring technology is not in the same level, and the emphasis of obtaining parameters is also different, this paper verified those monitoring results, definited each parameter obtained from different monitoring technology, discard the false and retain the true, the monitoring results have being used to optimize the fracture parameters, well net have being protracted in order to provide reference frame for avoiding fracture channeling,repeated fracturing and deployment of water injection wells.
