摘要:
以取心井岩心、测井及生产动态资料为基础,在储层构型理论指导下,采用“垂向分期”、“侧向划界”的思路,针对渤海海域J油田东二下段Ⅰ、Ⅱ油组三角洲前缘沉积砂体,按复合河口坝(复合水下分流河道)、单一河口坝(单一水下分流河道)2个层次进行了构型单元的逐级解剖。通过小层精细对比,认为研究区存在泥质夹层、含砾砂岩层、钙质夹层3种垂向分期识别标志; 归纳出曲线形态差异、岩性差异、厚度差异、高程差异、水淹特征差异5种侧向划界识别标志,重构了油田范围内以水下分流河道为骨架、河口坝砂体为主体,多个单一河口坝连片分布、水下分流河道交叉叠置的沉积特征。研究成果用于指导油田4个注聚井组调剖,单井日增油量10 m3。
Abstract:
Based on the data of coring well cores,logging,production performance,under the guidance of reservoir architecture theory,the reservoir architecture units of the delta front sandbodies from I and II formation of E3d2L in J oilfield were step by step dissected according to the two levels:composite mouth bar or composite underwater distributary channel and single mouth bar or single underwater distributary channel.According to the fine contrasting stratums,the research area has three kinds of vertical stage identification marks:shale interlayer,pebbly sandstone and calcareous interlayer.And then it was summarized five kinds of lateral delimitation identification marks:curve shape differences,lithology differences,thickness differences,elevation differences and flooding differences.Finally,it was reconstructed the sedimentary characteristics within the oilfield:underwater distributary channels as skeleton and mouth bars as the main body,the contiguous distribution of multiple mouth bars,and the cross superimposition of underwater distributary channels.The research results were effectively used to guide the profile control of four polymer injection well groups
