摘要
复杂断块大平房油田东营组储层为陆上曲流河相沉积类型,其中曲流河点坝相储集层为主要产油层,而该油田此相带储集层规模较小,表现为储层物性较差,连通性差,开采过程中生产动态复杂,造成注采体系不完善,水驱效果差,水驱采收率较低,通过以岩心分析资料和大量的测井、生产动态资料为基础,对各种沉积相标志的分析,研究了曲流河储集层微相组成及主要沉积微相特征,综合评价出Ⅱ、Ⅲ类储层,找出影响注水开发效果的各类因素,有针对性地对注采系统进行调整研究,提高水驱控制程度。
Complicated fault block reservoirs of Dongying Formation in Dapingfang Oilfield in Liaohe Oilfield is continental meandering channel deposits,of which,point bar reservoirs of meandering channels are the main oil producing zones and point bar reservoirs are characterized by small scale,poor physical properties and poor-communication.In the course of the development of the zones,the production performances showed complicated with imperfect injection-production system,poor water flooding effect and low recovery factor.The meandering channel microfacies and the main sedimentation microfacies are studied based on core analysis and a great deal of logging and production data as well as the sedimentation marker,as a result,type Ⅰ and type Ⅱ reservoirs are classified and evaluated and the factors affecting the effect of water flooding are found out,so pertinent adjustment on injection-production system has been done to improve the controlling degree of the water flooding.
