胡尖山油田从1996年10月开始投入开发,开采的初期未进行同步注水,随着开发时间的延长,累计采出程度不断增加,寻找合理的开发技术政策,提高油藏的最终采收率,减缓油藏自然递减,补充地层能量,抑制含水上升,实现油田高效开发,成为油田后期发展的所面临的主要问题。本文主要从胡尖山三叠系开发现状及存在问题入手,通过对A42(长1)、元162(长2)早期开发技术政策分析及评价,结合油藏工程及注采调整方法,总结适应胡尖山三叠系油藏合理的注水开发技术政策。
Hujianshan Oilfield was put into development from October 1996, and no synchronous water injection was carried out in the initial stage of mining. With the extension of development time, the cumulative recovery rate has been constantly increasing. Looking for reasonable development and technical policies and increasing the ultimate oil recovery, It is the main problem facing to slow down the natural decline of reservoirs, supplement the formation energy, restrain the rising of water content and realize the efficient development of oilfields. Based on the analysis and evaluation of the technical policies of early development of A42 (Chang 1) and Yuan 162 (Chang 2), combining with the reservoir engineering and the method of injection and production adjustment, this paper summarizes the current situation and existing problems of Hujian Mountain Triassic development, Jianshan Triassic reservoir reasonable waterflood development technology policy.
