块状底水油藏二次开发部署研究

Study on the two development of block bottom water reservoir

齐2-7-10块属于块状气顶底水油藏,目前面临高含水的开发后期,面对油井采油量低、开井率低、接近废弃的现状,近几年,在剩余油分布规律研究的基础上,寻找油藏的潜力方向,探索油藏目前开发中存在的矛盾,合理部署挖潜工作,提高油藏最终采收率,改善油藏开发效果。该块经过多年的勘探开发,随着侧钻技术以及水平井技术的应用,大幅提高了区块开发效果,为老油田二次开发奠定了基础。

Block Qi 2-7-10 belongs to the block gas reservoir with top and bottom water.At present,facing the late stage of high water cut development,facing the status of low oil production,low well opening rate and close to abandonment,in recent years,on the basis of the study of remaining oil distribution law,the potential direction of the reservoir is searched,and the contradictions existing in the current development of the reservoir are explored.Deploying and tapping potential work to improve the ultimate recovery and improve the reservoir development effect.After years of exploration and development,along with the application of sidetracking technology and horizontal well technology,the block development effect has been greatly improved,laying the foundation for the second development of old oilfield.
