摘要
印尼G区块地处太平洋板块、欧亚板块与印度-澳大利亚板块3个巨型岩石圈板块交汇处,历经复杂构造-沉积演化。运用测井地质研究手段,根据构造-沉积演化的研究成果,以宏观与微观的统一性认识作为预测依据,成功预测并发现印尼G区块发育3类低电阻率油气层,即构造成因、沉积成因及复合成因的低电阻率油气层。并从构造、沉积等角度,结合测井信息的响应特征,对低电阻率油气层的成因机理进行了分析、阐述。岩心铸体薄片分析资料、试油与生产等表明,该预测成果真实可靠。统计表明,低电阻率油气层占整个研究区油气层的23.1%,数量丰富,具有较大的挖潜空间,为研究区下步的产能接替提供了依据,扩大了研究区的储量规模。
The G block in Indonesia, situated at the intersection of the three huge lithosphere plates（Pacific, Eurasian and India-Australia plates）, has experienced complex structural and sediment evolution. In developing oversea gas-and-oil resources, one of the main problems in production is how to efficiently utilize the resources. In this study, we develop a method to identify the low resistivity gas-and-oil zones by using the achievement in the structural and sediment evolution and macro and micro logging geology methodology. Three types of low resistivity gas-and-oil zones are revealed. They are the structure, sedimentary genesis and complex genesis zones. Our methodology is successfully applied to the Indonesia G block. The data in the practice demonstrate that the ratio of the low resistivity gas and-oil zones to the whole gas-and-oil zones in the study is about 23.1 %. The result provides a guidance for searching the low resistivity gas-and-oil zones and hence is helpful for enlarging the development of gas and oil in the area.
