针对胡状集油田储层严重非均质的特点,将剩余油研究与储层微相研究紧密结合,总结了剩余油的分布特征及水淹层电测特征,通过地质工艺结合,选择与之相适应的工艺配套技术,以提高水驱波及体积,合理调整注水、产液结构,有效地遏制了油田的两大递减,实现了连续5 a 稳产,对严重非均质油藏的开发具有现实指导意义。

Aimming at serious heterogeneous reservoir in Huzhuangii Oilfield , and combining the reservoir sedimentary microfacies with the origin mechanism of remaining oil , remaining oil distribution and electric logging characteristics of water flooded layers are summarized. To select suitable methed to tap the rernaining oil and to increase output , and various corresponding matching techniques that is fit for geologic condition and technologica statue , reasonable adjusting intake and production profile. So that the reservoir sweep volum of injection is improved , and comprehensive decline and natural decline is controlled effectively. With abeve technologies , stable production of reservoir was accomplished during the last five years.
