水平井在江汉油区开发中的应用

On Application of Horizontal Wells in the Exploitation of Jianghan Oilfield

水平井在开采过程中具有泄油面积大、单井产量高等特点,已成我国陆相油田开发过程中的主要增产方式。随着江汉油区逐渐进入开发后期,面临剩余油挖潜和储量动用难度不断加大的困境,通过对江汉油区水平井的生产现状以及在低渗薄层油藏、稠油油藏、致密油藏的应用效果进行分析,表明大力推广应用水平井是提高油田开发效果的有效方式。针对水平井措施效果进行分析总结,提出了今后的研究方向。

Due to their advantages of larger oil drainage area and higher single--well producing rate, horizon- tal wells are mainly used to increase oil production in the exploitation of continental oilfield in China. As Jianghan oilfield is entering later stage of development, it has more difficulties in residual oil development and reserve utilization. This paper has discussed the production status about horizontal wells in Jianghan oil- field and analyzed their application effect in thin oil reservoir with low permeability, thick oil reservoir as well as dense oil reservoir. The analysis shows that their more application can effectively help enhance oil- field development. On the other hand, this paper puts forward further research direction on the basis of the analysis of the effect of horizontal well measures.
