摘要： 1984年塔里木盆地北部沙参2井实现我国古生代海相油气首次重大突破后,在塔里木、华北、扬子及准噶尔地块上发现一批大中型油气田。从烃源岩、储集层(体)、多储盖组合、古隆起、古斜坡控油、多期成藏、多期充注及封盖条件等方面,深入研究了大油气田成藏条件,并指出勘探方向,对在地质构造十分复杂的古生界发现更多大油气田,具有重要意义。

Abstract: The first major breakthrough of marine oil-gas reservoir of Paleozoic discovered from Shacan-2 Well in northern Tarim basin was made since 1984 followed by that a number of large-middle scale fields has been found in Tarim, North China, Yangtze and Junggar blocks. In-depth researches of the conditions for forming large scale oil-gas fields are presented in view of source rocks, reservoir body, multiple reservoir-caprock assemblages, palaeohigh, palaeoslope-controlled oils, multistage hydrocarbon accumulation, multistage charging and sealing condition, etc. and the exploration directions are pointed out. These are of great significance for seeking more domestic large scale oil-gas fields of Paleozoic with very complex geologic structures.

Key words: China, Paleozoic, source rock, hydrocarbon accumulation, condition, large scale oil-gas field, exploration direction
