延长油田油井动液面综合检测技术研究

Research on comprehensive testing technology of oil wells moving liquid level in Yanchang Oilfield

为了提高油井的出油率,同时加强油井内持续供液能力,针对延长油田的特性,提出了一种油井内动液面检测方法,并设计出相应的动液面检测系统,能够实现油井下动液面实施检测,介绍了油井内动液面浮筒检测法、压力计法、回声法,分析了动液面的检测原理和声波的选择,针对延长油田的特点,最终确定延长油田油井内动液面交叉偶极子阵列声波检测方法,并设计出相应的硬件系统。

In order to increase the oil production rate of oil wells and at the same time strengthen the continuous fluid supply capacity in the oil wells,in view of the characteristics of the extended oil field,a method for detecting the fluid level in the oil well was proposed,and a corresponding fluid level detection system was designed,which could realize the downhole the testing of the moving fluid level was introduced,the fluid level float inspection method,the pressure gauge method and the echo method in the oil well were introduced.The testing principle of the fluid level and the selection of sound waves were analyzed.In view of the characteristics of Yanchang Oilfield,the sound wave detection method of the cross dipole array of moving liquid level in Yanchang oil well was finally determined,and the corresponding hardware system was designed.
