【摘要】 若参1井见到了良好的油气显示,显示了若羌地区特别是南缘山前带具有较好的油气勘探前景。为了进一步推动该区油气勘探,根据前人研究成果、若羌地区地震资料以及若参1井钻井资料,对该地区石油地质条件进行了综合分析。研究认为:若羌地区侏罗系杨叶组砂砾岩和塔尔尕组泥岩组成良好的储盖组合;杨叶组暗色泥岩是较好的烃源岩;南缘山前带发育4排北东向构造,圈闭发育,是若羌地区有利的勘探区域。更多还原

【Abstract】 A fine hydrocarbon show has been indicated in the well Ruocan-1,showing a relatively favorable exploration prospect in Ruoqiang area,especially in its southern piedmont.To further promote the oil and gas exploration in this area,the petroleum geological condition has been analyzed comprehensively according to previous research results,seismic data in Ruoqiang area and drilling data of the well Ruocan-l.Research showed that the Jurassic glutenite of the Yangye formation and mudstone of the Taergar formation in Ruoqiang area composed a good reservoir-seal assemblage;the dark mudstone of the Yangye formation is a good source rock;and four series of Northeast-trending structural trap have been developed in the southern Piedmont which is a favorable exploration region in Rouqiang area.更多还原
