摘要/Abstract

摘要： 羌塘盆地位于青藏高原中北部特提斯构造域中段,是晚古生代一中生代特提斯体制下形成的一种复杂的、特殊类型的复合对称型前陆盆地,具有广泛的中生界海相沉积和中国最年轻的海相地层,沉积厚度可达万米。羌塘盆地中生代具有广泛分布且发育良好的烃源岩,烃源岩厚度大,最厚处在3000m以上,其中上三叠统的肖茶卡组、中侏罗统布曲组和夏里组有机质类型好、丰度高,有机质从成熟到过成熟均有分布,埋藏较好,其生油量巨大,是盆地油气的主要来源之一。以含油气系统理论为指导对其进行了全面分析,划分出了肖茶卡组(T₃x)-曲色组(J₂q)含油气系统、雀莫错组(J₂q)-布曲组(J₂b)含油气系统、夏里组(J₂x)-索瓦组(J₃s)含油气系统。

Abstract: Qiangtang basin lies in mid-segment of Tethys domain in north-central Qinghai-Tibet plateau, which is a complex and special type of compound symmetric foreland basin with Tethy an tectonic style from Late Paleozoic to Mesozoic. It has widespread Mesozoic marine depo-sition and the latest marine strata with thickness of over 10,000 meters. W ell-developed and widespread source rocks with the max. thickness of more than 3,000 m are found in Mesozoic Qiangtang basin, where Xiaochaka formation (T₃x) of Upper Trassic and Buqu formation (J₂b) andXili formation (J₂x) of Middle Jurassic are good in organic matter type and abundance as well as buried condition and distribution from matureto overmature in organic matter maturity. And it is one of major source of hydrocarbons in Qiangtang basin. This paper analyzed and classified in detail the petroleum systems such as T₃x-J₁q, J₂q-J₂b and J₂x-J₃s in Qiangtang basin.
