通过分析天然气及其伴生原油的地球化学特征,结合区域的地质构造形态,认为克拉美丽气田的油气在滴水泉西断裂两侧来源不同。断裂北部的油气来自滴水泉凹陷的石炭系腐殖型的烃源岩;断裂南部的油气主要来自石炭系烃源岩,混有部分来自东道海子凹陷二叠系腐泥型源岩供给的油。
By analyzing the geochemical characteristics of natural gas and its associated crude oil and combining with the geological structure of the region, it is considered that the sources of oil and gas in Kelameili gas field are different on both sides of the Quanxi fault. The oil and gas in the northern part of the fault came from the Carboniferous humic hydrocarbon source rocks in the Shuiquanquan depression. The hydrocarbons in the southern part of the fault mainly came from the Carboniferous hydrocarbon source rocks, partly mixed with the oil from the Permian sapropelic source rocks in the Dongdao Haizi Sag.
