流动单元的影响因素

Influential factors of flow unit

为解决油田中后期地层压力低、水驱效率低、含水率高、开发效果不理想的矛盾需要对储层的非均质性分析,而流动单元分析作为研究储层非均质性的一种新方法,通过分析发现沉积、成岩及构造作用对流动单元的形成有较大的影响。

The research on the reservoir heterogeneity were carried out to resolve the problems such as low formation pressure,low efficiency of water flooding,high water cut and unsatisfactory development results in the middle and later stage of oilfield.Flowunit analysis is a new way for reservoir heterogeneity research.It is found that sedimentary,diagenetic and tectonic processes contributeto the formation of flow units.
