印度尼西亚Jabung区块是南苏门答腊盆地油气勘探的主力区块,该区块油、气、水关系复杂,低阻油气层较难识别。研究中以多井地层对比为基础,抓住标准层和井震结合2个关键问题,准确认识油气藏。在油气藏特性认识的指导下,结合岩屑录井、气测录井中油气显示情况,利用多参数交会图版加强对测井资料的综合解释分析,准确识别低阻气层,有效提高了印尼Jabung地区测井资料解释符合率,增强了低阻油气层识别精度。试油与生产结果证明测井解释结论真实可靠。解释结果在该地区天然气勘探、生产中发挥了重要的作用。
The Jabung block in Indonesia is the main block for oil and gas exploration in the South Sumatra basin. The relationship between oil, gas and water in this block is complex and the low-resistivity oil and gas reservoirs are more difficult to identify. Based on the comparison of multi-well strata, the study grasped two key problems of combining standard layer with well-shaking, and accurately recognized the reservoirs. Under the guidance of the understanding of reservoir characteristics, combined with the oil and gas showings in cuttings logging and gas logging, the multi-parameter rendezvous plate is used to strengthen the comprehensive interpretation and analysis of well logging data and accurately identify the low-resistivity gas reservoirs, which effectively improves the performance of Jabung Regional logging data to explain the coincidence rate, enhanced low-resistivity reservoir identification accuracy. Test oil and production results prove that logging interpretation is true and reliable. Interpretation of the results in the area of natural gas exploration and production has played an important role.
