摘要
针对L油田进行早期弱凝胶驱见效规律和效果评价。注采动态分析显示,弱凝胶驱时受效井含水越低,含水漏斗越不明显,且注入端吸水指数降幅、压力上升值和渗流阻力也越大。将整体技术和经济效果分析结果与其他化学驱油田进行类比,可知L油田早期弱凝胶驱开发效果较好。
This research aims to figure out the response performance and effect evaluation of early weak - gel flood-ing in L oilfield. Dynamic data of injection production show ： for early weak - gel flooding, the lower the water cut of response production well is, the less obvious the water cut funnel become, and the bigger reduction of water in-jectivity index, injection pressure and seepage resistance are. Compared with other chemical flooding oilfields, the technical and economical analysis shows that early weak - gel flooding has better development effect in L oilfield.
