Reservoir Automatic Recognition Using Logging Evaluation in Deep Red Bed of Dongying Sag
-
摘要: 东营凹陷深部储层是干燥沉积环境下的一套红层，其中的沙四下和孔一中储层厚度较大，有较大的勘探潜力。本文根据研究区大量的测井数据整理和统计，绘制了有利储层、储层、非储层的交会图和雷达图，分析和优选出描述该区域储层最主要的5种测井曲线（AC、SP、GR、R4、CNL）。然后统计区域所有井的地质分层、试油和测井数据，制作出沙四下和孔一中有利储层、储层、非储层的定量评价模板。最后根据评价模板，研发出自动评价软件。用该软件，无需再做复杂的测井综合解释，可直接判识储层物性特征，具有一定的应用价值。Abstract: The deep reservoir of Dongying sag is a set of red bed under dry sedimentary environment. The reservoir of Es4x and Ek1z has large thickness and great exploration potential possess. This paper draws the cross plots and radar maps of favorable reservoirs, reservoirs and non-reservoirs by a large number of logging data collation and statistics in the study area. Five main logging curves(AC, SP, GR, R4, CNL) describing reservoirs in this area are analyzed and optimized. Then, the geological stratification, oil testing and logging data of wells in this area can be used to obtain quantitative evaluation templates for favorable reservoirs, reservoirs and non-reservoirs of Es4x and Ek1z layer. Finally, automatic evaluation software is developed based on the evaluation template. With this software, the physical properties of reservoir can be directly identified without complex logging interpretation, and it has certain application value.
