摘要
就中层物源方向和影响范围进行精细的研究,为东方A气田中层进一步勘探开发提供良好的研究基础。研究区中深层由于钻遇井点少,发育有泥底辟作用,浅海相沉积环境,多重物源沉积等因素的影响,给物源的分析精度上带来了许多难点。所以用传统的针对目的层物源分析方法无法较好判断物源方向和影响范围。本文通过多种统计分析在区域上建立判别函数搭建各个物源的重矿物模式格架,在综合各方面资料充分论证判别函数和重矿物模式格架在目的层应用可行性的基础上,利用已知井点资料的控制,推导出研究区中深层的物源方向和影响范围,以此探讨浅海相低井控区物源分析方法,为今后地质建模储层物性预测等研究提供重要数据基础。
In this paper, fine research on the direction and influence range of the middle source is proposed, which provides agood research basis for the further exploration and development of the middle A gas field.In the middle of the study area, there are manydifficulties in the analysis accuracy of the source of the source due to the small amount of drilling wells, the development of mud pond,shallow marine sedimentary environment and multiple source deposition.Therefore, the traditional source-source analysis method cannot be used to judge the source direction and influence range.In this paper, a large number of statistical models are used to construct theheavy mineral model framework of each source in the region.Based on the comprehensive feasibility of the discriminant function andthe heavy mineral model grid, The author analyzes the source direction and influence range of the deep source in the study area, andexplores the provenance analysis method of the shallow marine low well control area, and provides important data base for the futuregeological prediction reservoir physical prediction The.
