摘要: 经地球化学分析和研究认为彩南油田的天然气为煤型伴生气,其中彩17井八道湾组天然气可能为煤层气.原油为煤系成为油。阜康凹陷中、下侏罗统煤系地层为主要烃源岩。阜康凹陷斜坡带是寻找油气的有利地区,中、下侏罗统煤层是寻找煤层气的有利层系。

Abstract: The geochemical analysis and study show that gas from Cainan oilfield is coal-type associated gas, in which gas from Well Cai17 (Badaowan Formation) is possibly coal bed gas and oil generated from coal. The Middle-Lower Jurassic coal measures in Fukang sag are the main source rock. The slope zone in Fukang sag is advantageous area for 011 and gas prospecting. The coal seams in the Middle-Lower Jurassic are advantageous sequences for coalbed gas prospecting.

Key words: Cainan oilfield, Hydrocarbon origin, Coal-type gas, Coalbed gas, Biomarker
