Abstract

Abstract:

Beach-bar reservoirs are widely deposited in the second member of Shahejie Formation in Banqiao oilfield, Huanghua depression. The spatial superposition relationship between beach-bar sand bodies is unclear, thereby restricting further development and remaining oil potential tapping in the oilfield. Based on extensive drilling data and the condition of closely spaced wells, beach-bar sand bodies in the study area were divided into three levels, compound bar (fifth-order architectural unit), single bar (fourth-order architectural unit), and accretion body interior of single bar (third-order architectural unit). The identification marks and spatial distribution of the architectural units interior of beach-bar reservoirs were discussed to establish the corresponding sedimentary models. Single bar sand bodies were identified and divided by summarizing six identification marks such as the difference of relative elevation, the pattern of logging curves, and the number of interlayers. Results show that the spatial superimposition relationship of single bar sand bodies varies in different tectonic positions (or fault blocks), mainly showing the distribution models of lateral migration, vertical superposition, and insulation. This paper further analyzed logging identification marks of the third-order architectural unit interior of single bar (interlayers) using coring data and combined with present deposition and outcrop to anatomize the architecture of single bar sand bodies. The single bar can be divided into one or multiple accretions, between which 0.1-1 m thick muddy interlayers are commonly developed. The interlayers adjacent to the lakeshore are nearly horizontal and inclined in a small angle (2°-5°) towards the center of the lake. The distribution of oil/gas in beach-bar reservoirs is affected by the architecture of the sand bodies. The fourth-order interface between single bar and the third-order interface interior of single bar divide the beach-bar reservoir into isolated fluid systems, thereby leading to the differences in oil-bearing properties.

Key words: beach-bar, reservoir architecture, distribution model, Banqiao oilfield, Huanghua depression, Shahejie Formation

摘要：

滩坝是黄骅坳陷板桥油田沙河街组二段广泛发育的沉积类型,滩坝砂体空间叠置关系的认识制约了油田的进一步开发和剩余油挖潜。应用研究区丰富的钻井资料和密井网条件,分复合坝(5级构型单元)、单一坝(4级构型单元)和坝内增生体(3级构型单元)三个级次进行解剖,探讨了滩坝储集层内部构型单元的识别标志及空间展布特征,最终建立相应的沉积构型模式。总结了相对高程差异、曲线形态、夹层个数等6种单一坝识别标志,对单一坝进行识别与划分;不同构造部位(不同区块)的砂体空间叠置关系有所差异,主要有侧向迁移型、垂向叠加型和孤立型3种单一坝分布模式;分析了单一坝砂体内部3级构型界面(夹层)的井上识别特征,并结合现代沉积和露头,对单一坝内部进行构型解剖。单一坝内部可分为一个或多个单一增生体,增生体之间通常发育0.1~ 1 m厚的泥质夹层。夹层靠近岸线近水平分布,向湖中心方向以低角度倾斜,倾角约2°~5°。滩坝储集层油气分布受砂体构型的影响,单一坝之间的4级界面、单一坝内部的3级界面都可以将滩坝分隔成相对独立的流体系统,从而导致含油气性的差异。
