摘要
针对大庆油田和海拉尔探区斜井资料解释中存在的实际问题,从不稳定渗流力学理论入手,开展了斜井试井解释方法研究,建立了斜井三维渗流问题的压力偏微分方程,采用Newman乘积法求解得到井底压力公式。在此基础上,形成了斜井试井解释双对数曲线理论图版。通过典型曲线拟合分析,计算出储层动态参数。该方法解决了以往采用直井模型分析斜井压力资料误差较大的问题,提高了斜井试井资料的解释精度。经现场应用效果良好,达到了合理评价斜井储层的目的。
To practical problems appeared in data interpretation for inclined well at the exploration area of Daqing oilfield and Hailar,From the stable flow mechanics,the study is carried out to establish a three-dimensional partial differential equations and obtain bottom hole pressure formula by using inclined pressure,and the method by the product method of Newman.On this basis,the theory plot of the double logarithmic curves of well test interpretation for Inclined well is formed,and through the typical curve fitting analysis,the dynamic parameters of the reservoir are calculated.The method solves the problem of the big errors by using vertical well model to analyze pressure data of inclined well and improves the accuracy of inclined well test data interpretation.The field applications show that the results are good,which reaches subjective of evaluating reservoir of inclined well reasonably.
