摘要
尽管小而分散的侏罗系油藏具有建产效益高、初期产量高天然能量充足等特点,但在开发过程中容易因采液强度过大导致底水快速锥进,形成地层的水淹,从而影响油藏的最终采收率。针对此问题开展了Y47延10油藏高效开发技术对策的研究。通过对开发矛盾、储层初期改造方式、开发技术政策调整等方面进行总结分析,找出了Y47延10油藏高效开发技术对策。矿场实践表明:2019年油田各主要指标有所好转,自然递减率降至9.5%,含水上升率降至0.9%,预测油藏最终采出程度将超过40%,为同类油藏开发提供参考意见。
Although the small and dispersed Jurassic reservoir has the characteristics of high initial production and sufficient natural energy,it is easy to cause rapid coning of bottom water and formation water flooding due to the excessive liquid production intensity in the development process,thus affecting the final recovery rate of the reservoir.In order to solve this problem,the technical countermeasures for high efficiency development of Y47 Yan 10 reservoir were studied.Through the summary and analysis of the development contradiction,the initial reservoir transformation mode,the adjustment of development technology policy and other aspects,the high-efficiency development technology countermeasures of Y47 Yan 10 reservoir were found out.The field practice showed that,in 2019,the main indexes of the oil field were improved,the natural decline rate was reduced to 9.5%,the water cut rise rate was reduced to 0.9%,and the final recovery degree of the reservoir was more than 40%.
