摘　　要：在单井反褶积方法的基础上,研究了具有井间干扰效应的多井压力—流量反褶积试井方法,并将井间干扰压力响应从井自身的压力响应中分离出来,分离后的井自身在单位流量下的压力响应可以用于油藏模型诊断及常规试井分析。现采用合成数据和数值模拟数据对此算法进行了验证分析,结果准确可靠。Multiwell deconvolution of pressure and flow rate taking interwell interference effect into account is studied on the basis of single-well deconvolution.The interwell pressure interference is extracted away from the total pressure response and then the pressure response of testing well itself,under the condition of unit flow rate,is obtained.This obtained pressure response can be used for reservoir model diagnosis and other conventional interpretation.Some sets of numerically simulated transient pressure data with interwell pressure interference were studied,which demonstrated that the developed algorithm works well for multi-well deconvolution.
