为解决东辛油田永1断块井间干扰及连通性问题.开展了一口观察井与四口激动井的干扰试井设计.测试中四口激动井依次激动,根据观察井测得的井底压力资料判断井间连通性.根据不稳定渗流理论和压降叠加原理建立了干扰试井判断井间连通性的方法.通过分析压力曲线以及压力导数曲线的响应特征,依次分析了测试井组的井间连通性.根据分析结果采取了注采调整措施,取得了较好的开发效果,并验证了所采用方法的正确性.
In order to solve the inter-well interference and connectivity problems of Yong 1 fault block in Dongxin Oilfield, an interference well test design of one observation well and four stimulation wells was carried out. In the test, four wells were excited in sequence. According to the well bottom Pressure data to determine the connectivity between wells.According to the theory of unstable seepage and the principle of pressure drop superposition, a method to determine well connectivity between disturbances is established.Through analyzing the response characteristics of pressure curves and pressure derivative curves, Cross-well connectivity. According to the analysis results, the injection and production adjustment measures have been taken, and good development results have been obtained. The correctness of the method adopted has been verified.
