无线压力传输装置在压裂驱油监测中的应用

Application of Wireless Pressure Transmission Device in Monitoring of Fracturing Flooding

在三类油层压裂驱油试验中,为及时掌握压裂驱油全过程中压力变化,避免压窜风险,采用无线压力传输装置对压裂前、压裂中、压裂后进行了实时压力监测。从监测数据准确性、信号传输稳定性以及油、水井适用性三方面,对该装置在压驱监测中的应用效果进行评价。

In the class III reservoir fracturing flooding test,in order to grasp the pressure change and avoid the risk of fracturing channeling in the whole process of fracturing oil displacement in time,the real-time monitoring is carried out by using the wireless pressure transmission device before,during and after fracturing.The application effect of the device is evaluated in fracturing monitoring from three aspects:the accuracy of monitoring data,the stability of signal transmission and the applicability of oil and water wells.
