摘要

摘要: 单砂体研究是高含水开发区中后期层内剩余油挖潜、改善开发效果的重要基础工作。笔者通过岩心观察,结合电测曲线特征,总结出研究区等高程、叠置砂体、沉积相变3种砂体对比模式及水下分流河道、河口坝、远沙坝3种砂体成因类型。最后结合动态注采对应关系进行单砂体展布规律分析。研究结果为注采调控提供地质依据,为精细注水示范工程的开展奠定基础,对揭示储层非均质性和预测剩余油分布都具有重要意义。

Abstract: The study of a single sandbody may help establish a basis for the development of residual oil and improvement of exploration success. The present paper gives a detailed description of three models such as contour correlation, superimposed sandbody correlation and sedimentary facies correlation models on the basis of core observation and well logs, and three genetic types of sandstones including the subaqueous distributary channel, channel mouth bar and distal bar sandstones. The single sandbody distribution is also discussed in the light of the dynamic injection-production relationship. The results of research in this study will provide a geological basis for the injection-production adjustment, examination of the heterogeneity of the hydrocarbon reservoirs, and prediction of residual oil distribution in the study area.
