本文基于脉冲试井的基本原理,对肇70-21超前注水实验区块4口油水井的测试结果进行分析,最终对井间连通情况做出简单的分析。大庆在目前的开发阶段,产量自然递减幅度、含水上升速度加快,针对这种情况,需要搞清剩余油和注采对应关系、连通性判断、以及相应的注水反应,从而制定出行之有效的调整方案。因此脉冲试井技术要求在复杂的地质状况及较多的井间干扰因素影响下,利用高精度测试方法,为油田的开发调整提供准确有效的开发指导资料。
Based on the basic principle of pulse well test, this paper analyzes the test results of 4 oil-water wells in Zhao 70-21 advanced water injection experimental zone, and finally makes a simple analysis of the well connectivity. In the current development stage of Daqing, the rate of natural decline of output and the rate of increase of water cut are faster. In view of this situation, it is necessary to find out the correspondence between the residual oil and injection-production, the judgment of connectivity and the corresponding water injection reaction so as to formulate an effective adjustment of travel Program. Therefore, the pulse well testing technology requires the use of high-precision testing methods to provide accurate and effective development guidance for the development and adjustment of the oilfield under the influence of complex geological conditions and many inter-well interference factors.
