微地震监测水驱前缘应用效果分析

Analysis on Application Effect of the Microseismic Monitoring Technology in Monitoring the Waterflood Front

微地震测试技术广泛应用于油田注水开发中,通过该测试能够确定水驱前缘、注入水波及面积、优势注水方向等。实例分析表明,微地震测试的结果基本符合实际生产特征,具有一定的合理性,但是在实际施工和计算的过程中存在一定的误差。因此,在应用微地震技术指导油田注水开发的过程中,需要对测试的结果进行合理分析,排除测试产生的误差。

The microseismic technology has been widely applied in monitoring oilfield water-flooding development; it can accurately determine the water-flood front, the swept area of injected water and predominant water injection direction. Case analysis indicates that the result of micro seismic testing coincides with the production performance, and has certain rationality, but there may be errors in actual construction and computational process. Therefore, during application of the microseismic technology in guiding oilfield water-flooding development,reasonable analysis on the test results need be carried out to eliminate the errors.
