In order to enhance ESP well management and effectively judge downhole working condition in QHD32 -6 oilfield, a pressure build-up curve model is created for ESP wells based on the working principle, fluid mechanics and hole structure, as well as analysis of the relationship between ESP well pressure build-up value and time. This model can construct and analyze pressure build-up curves of ESP well under different working conditions. Case application shows that this mudel is relatively accurate in a-nalysis of ESP well working condition combining with other production and testing data, thus providing theoretical basis for field operation.%为加强QHD32 -6油田电泵井管理和有效判断电泵井井下工况,根据电泵井工作原理和井下流体力学理论,结合电泵井结构特征,对电泵井憋压值与时间的变化关系进行论证分析,从而建立了电泵井憋压曲线模型.该模型可绘制并分析不同工况下电泵井憋压曲线及其对应规律.实际应用表明,该电泵井憋压曲线模型(结合其他生产及测试资料)可实现对电泵井井下工况的相对准确分析,为现场施工提供理论依据.
