低渗、特低渗油层试油技术

Well Test Technology for Low Permeability and Excessive Low Permeability Reservoir

针对陕北中生界地层地质特点，运用理论研究与数理统计相结合的方法，通过1995、1996两年90多口井、180多层的试油和210余井次的压裂实践检验，摸索出了一套适合陕北中生界延长统低渗透地层试油的选井选层原则、不同油藏类型的射孔方式、打开程度以及压裂改造模式，形成了一套比较适合该地区地层地质特点的试油技术，取得了显著的勘探效果，为低渗透油田试油的选井选层和压裂改造提出了新的途径和方法，具有很强的实用性和借鉴性。同时也为其它低渗透油气田的勘探开发提供了一些可供借鉴的方法和经验。

According to the geological properties of Mesozoic era in Shanbei, using the theory study and mathematical static rnethod, performing well testing more than 90 wells/180 intervals and hydraulic fracturing more than 210 wells,one set of well testing technology is developed to suit the test of this region. This set of technology can solve the problem of principle for choosing wells /intervals,perforating manner in different reservoir and treating pattern of hydraulic fracturing.This kind of technology gave a new way and method to well test in the low perrneability reservoir.
