电阻率成像法在某油田作业区漏油调查试验

Investigation on Oil Leakage in an Oilfield by Electrical Resistivity Tomography

为了查明某油田漏失点通道情况,为堵漏施工提供依据,首先采用电阻率成像法对该测区的窜漏情况进行调查实验,然后根据电阻率成像推测出该测区内的窜漏通道及与漏点相关的采油井,为采用复合化学凝胶堵漏技术治理窜漏提供依据。本次试验研究结果证明了电阻率成像法在超浅层油区找漏点的可行性,可为以后在石油开采中的油气窜漏调查提供借鉴。

In order to find out the situation of leakage point passage and provide a basis for leakage plugging in an oilfield, this paper adopts the electrical resistivity tomography(ERT) to investigate the leakage in this area at first. Then according to the electrical resistivity tomography, the leakage point passage and the related production wells in the survey area can be inferred, providing a reliable basis for using compound chemical gel plugging technology to control the leakage. The results show that ERT is an effective method to investigate the cause of leakage in very shallow layer reservoir, providing reference for detecting the leakage of oil and gas in oil productionin future.
