摘要
在桥口油田沉积微相研究和划分的基础上 ,本文对河道砂微相储集层沉积特征包括岩性特征、粒度分布、砂体展布、储层物性和储层非均质性等进行了全面的研究 ,认为河道砂微相储集层在油田开发早期是主力油层 ,在目前油田处于中高含水开发阶段 ,剩余油挖潜的主要对象仍然是此类层 ,并提出剩余油分布的类型 ,以便为油田后期制定调整挖潜方案提供参考。
On the basis of depositional facies study and division in Qiaokou Oilfield, this paper completely researches the reservoir depositional characteristics of channel sandstone microfacies, including lithologic feature, grain size distribution, sand body spread, reservoir properties and heterogeneities etc. It is recognized that the microfacies reservoir is the main oil layers in early oilfield development. The depositional characteristics and interbedded heterogeneity determine that the main object of remaining oil production is also the layers in mid-high water cut period.\;
