摘要(Abstract):
松辽盆地北部深层天然气绝大部分为干气,气源对比很困难。本文采用间接对比法,将源岩与天然气储层沥青中的生物标记物进行对比,认为深层天然气主要来自侏罗系和登娄库组地层。
Gas source correlation in north part of Songliao basin is very difficult because most deep natural gas is dry. This paper correlates the source rocks with biology marks in natural gas formation asphalt by adopting indirect correlation method, recognizing that deep natural gas mainly comes from Jurassic and Denglouku Formations.
