摘要

依据物系(如地下烃类体系)存在状态的内、外因条件和原理

结合塔里木盆地地质、物探、地化、测试等有关资料和国内外研究成果

论述了该盆地已知油气田(藏)地下烃类体系主要赋存形式

以及油气运移的可能模式。地下烃类主要以凝析气或者带轻质油环、或底油的凝析气形式赋存在凝析油气田(藏)中。在低地温、油气生成门限和生成高峰埋深大的特定地质条件下

初次运移是以微裂隙作为主要排出途径

二次运移以油溶于气和游离态油相为主。

Abstract

According to the conditions and principles of object occurrence and in association with the data of geology

geophysical exploration

geochemistry and testing

it is pro-posed that hydrocarbons in the Tarim Basin are preserved in condensate oil and gas fields(pools)mainly as condensate gas or condensate gas with light oil-rim or bottom oil.Un-der specific geological conditions of low geothermal temperature and great burial depth in threshold and peak of oil-gas generation

the primary migration was finished through mi-crofractures

and the secondary migration took the form of gas dissolved oil and free state oil.
