| 摘 要： | 考虑到生产历史、油藏非均质、多井以及油水两相流等特征建立了数值试井解释模型(包括生产阶段和关井阶段),采用快速、稳定的流线方法进行求解,得到关井测试时的压力场、饱和度场和流线分布,沿每条流线建立流线数值试井解释模型,并对由测试井发出的所有流线进行联立求解,得到关井后的压力响应。对压力响应和测压数据进行自动拟合或手动拟合,可得到试井解释参数。理论和应用实例验证了本方法的可靠性及实用性。

| Abstract: | In consideration of the characteristics of producing history,reservoir heterogeneity,multi-well and oil-water two-phase flow,a model for numerical well test interpretation(including producing phase and shut-in phase) was established.The pressure field,saturation field and the distribution of streamlines for shut-in well can be obtained with a quick and stable streamline method to solve the model.The streamline numerical well test interpretation models along all streamlines were established.All the streamline equations were solved together,and the pressure response for the shut-in well was determined.The well test interpretation parameters could be obtained by manually matching or automatically matching the pressure response and the tested pressure.The reliability and practicability of this method were identified by theory and field data analysis. |
