叠合盆地具有多种赋存状态的气源,除常规干酪根和古油藏外,分散可溶有机质是其重要直接气源,因其具有生气潜力大、分布空间广泛和催化作用参与而易于裂解的特征成为海相层系高演化区域气源的重要类型.通过对海相层系长期演化、多样性生气聚集过程的地质地球化学分析,利用三元地球化学示踪体系,研究塔里木盆地和田河气田天然气的来源和聚集过程,认为和田河气田天然气为深部分散可溶有机质高演化裂解成气沿断裂带长距离运移成藏的产物.这一结论对进一步扩大塔里木盆地台盆区油气勘探领域具有重要意义。
In addition to the conventional kerogen and paleo-oil reservoirs, the superimposed basins have a variety of gas sources. Dispersing soluble organic matter is an important direct source of gas because of its potential to generate gas, the wide distribution of space and the participation of catalysis The characteristics of the pyrolysis are important types of gas source in the high evolution area of the marine strata.Based on the geo-geochemical analysis of the long-term evolution and diversity of the marine strata, the ternary geochemical tracing system is used to study the geo-chemical properties of Wada It is concluded that the natural gas in the Hetianhe gas field is the product of long-distance migration and accumulation of deep disperse soluble organic matter into gas along the faults.This conclusion is of great value to the further expansion of oil and gas exploration in the Tarim Basin, Tarim Basin The area is of great importance.
