| 摘 要： | 南羌塘坳陷D2井中侏罗统曲布组海相碳酸盐岩大部分为差—好烃源岩级别,少部分为非烃源岩级别,有机质母质类型以Ⅱ型为主,热演化处于成熟—高成熟阶段。油源对比分析表明,羌D2井曲布组白云岩和含沥青角砾岩中油质沥青来自该组地层灰岩烃源岩,具自生自储性质。同时,中侏罗统雀莫错组灰黑色泥页岩作为烃源层也存在提供油源的可能性。

| Abstract: | The Mid-Jurassic Qubu carbonate core samples were collected from Well Qiang-D2 that lies in the South Qiangtang Depression of Tibetan plateau. The Qubu carbonate rock consists mainly of gray to dark-gray micrite, gray-brown grainy limestone containing grainy dolostone. Geochemical analysis shows that the Qubu rock varies in maturity from mature to high mature. Most of the rock are poor to good source rock with dominating Type-Ⅱorganic matter. The oil-source correlation displays that the asphalt diffused within Qubu dolostone and oily breccia cames from the Qubu limestone source rock. Besides, the Quemocuo dark-gray shale probably is another source rock supplied. |
