我国不同赋存状态烃类气体的研究现状与展望

RESEARCH SUMMARY AND PROSPECTSOF HYDROCARBON GASES PRESERVEDIN DIFFERENT STATES IN CHINA

不同赋存状态烃类气体（包括游离的天然气、吸附气、酸解气、水溶气和油溶气）研究对于烃源岩评价、天然气成因判识、油气复合关系研究，油气源对比和油气勘探均具有十分重要的理论和应用价值。我国经过“六五”、“七五”和“八五”期间组织天然气地学攻关，在该领域内取得了较大进展。综述了我国不同赋存状态烃类气体的研究现状，分析了研究中存在的几个问题，并展望了其理论和应用前景。

Study of hydrncarhon gases preserved in different states , including a free natural gas , an absorbed gas , an acid-desolved gas and an oil-desolved gas , is of very important theo- retical and practical values for evaluating source rocks , recognizing natural gas origins , re- searching oil-gas mixtures , oil-gas source correlation and oil-gas exploration. Through natural gas geological research organized in the sixth , seventh and eighth five-year plans in China , great progress have been made in the research of the gases. In this paper research results, problems and prospects of the gases are summarized.
