印度尼西亚Jabung地区低阻气层综合识别技术

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.

Comprehensive Logging Evaluation of Low Resistivity Oil-gas Reservoirs in Jabung Block, Indonesia

Jabung block is the major oil and gas exploration block of South Sumatra basin in Indonesia. In this block, the relationship of oil, gas and water is very complicated and this makes it very difficult to iden-tify the low resistivity gas reservoirs. Based on the strata correlation, the reservoirs are recognized precise-ly after dealing with the two key points of standard layer and well-seismic combination. Under the guide-line of the characterisucs of reservoir, in combination with the oil and gas shows and cross-plot, compre-hensive logging evaluation was carried out and thus improved the identification precision of low resistivity gas reservoirs. The interpretation results are proved to be reliable by testing and production and thereby played an important role in the exploration and production of this block.
