针对S105块馆三下储层非均质性认识不清的问题,综合运用岩心分析资料和测井解释资料,对该区储层宏观非均质性,包括平面非均质、层内非均质和层间非均质性进行了研究。结果表明,S105块馆三下亚段2、3号砂层内非均质性较强,1号、4~6号砂体层内非均质性较弱;3号、5号砂体连续性很好;1号、6号砂体连续性较好;2号砂体连续性不好;商105-x2、商106-2、商106-3等井区层间非均质性较强。
In view of the unclear understanding of the reservoir heterogeneity in the third block of S105 Block, the paper uses the core analysis data and well logging interpretation data to analyze the macro-heterogeneity of the reservoir in this area, including planar heterogeneity, Mass and inter-layer heterogeneities were studied. The results show that the heterogeneity of the sand bodies of No.3 and No.3 sand bodies in S105 Block is strong, and the in-layer heterogeneity of sand bodies Nos. 1 and 4 ~ 6 is weak. The No.3 and No.5 sand bodies are continuous The sand body of No. 1 and No. 6 is better in continuity; the continuity of No. 2 sandbody is not good; and the inter-layer heterogeneity is strong in the well 105-x2, Shang 106-2 and Shang 106-3 .
