水平井在具有气顶的普通稠油油藏开发中的应用——以孤东油田四区为例

Application of Horizontal Well in Ordinary Heavy Oil Reservoir with Gas Cap—Take No.4 Area of East Gudao Oilfield as an Example

目前对具有气顶的普通稠油油藏提高采收率方面的研究甚少,主要矛盾是在合理利用气顶能量的同时,最大限度地提高原油的产量但又不至于发生气窜。通过对实例的研究,采用水平井进行开发,在进行水平井参数优化的基础上,解决了该矛盾。

The study on enhancing oil recovery of ordinary heavy oil reservoir with gas cap is much less.The main conflicts are that the oil production is raised as much as possible and the gas channeling won't occur when the energy of gas cap is utilized rationally.According to the study of a example,the conflicts can be solved by introducing the technology of horizontal wells on the basis of optimization of parameters of horizontal wells.
