松辽盆地油气田分布规律的认识演进和海拉尔盆地油气分布规律--献给松辽盆地石油勘探50周年

松辽盆地及大庆探区勘探50年来,仅大庆探明石油地质储量就超过57×108t,为国家生产原油超过18.2×108t.该文介绍了松辽盆地50年来有关油气分布规律研究、认识的演进及对海拉尔盆地油气分布规律的基本认识,突出体现了"源控论"观点;肯定陆相生油理论对于大庆油田等一大批油气田的发现和探明所具有的指导意义,特别强调了这是对陆相生油理论的特大贡献;指出了50年勘探经历的背斜构造油藏、向斜岩性油藏、断陷断块油藏等三大阶段以及相应出现的三个油气储量增长高峰期,也是对石油地质理论的三次重大贡献.三大阶段的表现宏观上明确,而具体界限模糊,各阶段有起点,无终点.三大理论对各个阶段的作用呈叠瓦状显现.

Oil and Gas Fields Distribution Rules in Songliao Basin and Oil and Gas Distribution Rules in Hailaer Basin--To 50th Anniversary of Petroleu1 Exploration of Songliao Basin

During 50 years of exploration in Songliao Basin and Daqing area, 5.7 billion of OOIP was proved in Daqing, and 1.82 billion of oil was produced. This paper introduces the study on oil and gas distribution in the past 50 years, progress in recognition and understanding on oil and gas distribution in Hailaer Basin, emphasizing the view of "source controlling theory". It affirms that continental oil generation theory directed the discovery and proof of a lot of oil fields including Daqing, especially stresses that Daqing's discovery is a great contribution to continental oil generation theory. It indicates that 50 years exploration experienced three stages including anticlinal structural reservoir, synclinal lithologic reservoir and rift fault block reservoir, and correspondingly appeared three peaks of oil and gas reserves increase, and also three contributions to petroleum geology theory. The three stages have definite macro-exhibit but faint limit. They have starting point without end point.
