摘要

考虑五号桩油田特低渗油藏的整体开发井网部署,有必要对压裂过程中裂缝大小和方位进行实时检测,为此,结合油藏及现场地面概况,引入并实施了电位法井间检测技术。详细阐述了该技术的测试原理、测试仪器系统、测试工艺及后期数据处理方法;电位法井间检测技术共在五号桩油田应用5井次,其中,桩74-14-12井的裂缝检测认为该井主要存在两条大裂缝,裂缝长度为97m和83m,方位为75°和240°,其中,一条裂缝伸向水井是导致该井压裂后高含水的原因,通过对应水井的停注控水,该井获得日增油3t的效果。电位法井间检测技术的应用为后期压裂效果分析和井网部署提供了重要依据,同时也进一步说明该技术的实用性及今后的推广前景。
Considered the overall developing and well pattern deployment of Wuhaozhuang oilfield ultra low per meability reservoir, it is necessary to carry on the real-time monitoring of the fracture size and orientation in the process. Therefore, combining reservoir and ground situation, monitoring technology based on the electrometric method interwell has been introduced and implemented. In the article,the test principle, measurement and system, testing processand post data processing has been elaborated in detail. The technology has been applied 5 well-time. Among which, itis considered two large fracture existed in 74-14-12 well,the fracture length is 97 m and 83 m, the position is 75° and240°. One fracture extended to the water well and causedhigh watery after the well is fractured. After stopping waterinjection, 3 t oil has been enhanced daily. The application oftechnology has provided important reference to the post fracturing and well pattern deployment, and the article furtherexplained its usability and promoted prospect.
