Application of monitoring technology based on the electrometric method inter well in fracturing monitoring

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.
