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,原油为煤系成油。阜康凹陷中、下侏罗统煤系地层为主要烃源岩。阜廉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。
The geochemical analysis and study show that gas from Cainan oilfield is coal-type associated gas.in which gas from Well Cail7(Badaowan Formation)is possibly coalbed 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 oil and gas prospecting.The coal seams in the Middle-Lower Jurassic are advantageous sequences for coal bed gas prospecting.
