锦607块剩余油分布规律研究及挖潜应用

Study of the Distribution Rule of Surplus Oil for Jin 607 Block and Its Tapping Potential

锦607块为薄互层状边底水稠油藏,由于受构造和沉积相双重影响,油水关系非常复杂。为了提高区块开发效果,在开发后期有效动用区块剩余油,进行了锦607块剩余油分布研究。以单井为切入点,从平面、纵向立体分析,通过精细地质研究与监测资料有机结合,准确判断剩余油富集区,逐步认识油层的剩余油分布规律,为下步挖潜提供依据。通过近两年的工作,对区块各油层组的剩余油分布规律有了深入认识,并展开综合挖潜治理,取得丰硕成果,同时对水淹稠油油藏开发也具有指导及借鉴意义。

Jin 607 block is the thin and interbedded edge-bottom water oil reservoir and due to the dual influence of construction and deposition,the oil-water relation is very complex.In order to improve the development effect of block,in the later period of development,it has taken advantage of the surplus oil in block effectively and taken the distribution study of surplus oil in Jin 607 block.Taking the single well as the entry point,it has taken stereoscopic analysis comprehensively and through the organic combination of fine geological study and monitoring material to judge accurately the enrichment region of surplus oil and then gradually learn the distribution rule of surplus oil in oil layer so that to provide foundation for the following tapping potential.Through the works in recent two years,we have got a deep recognition of the distribution rule of surplus oil for each oil layer in the block,besides,it has developed comprehensive tapping potential governance and got rich achievement,which meanwhile has guiding and referential significance for the oil development of water logging heavy oil.
