摘要: 针对地球上普遍存在的走滑构造现象有大型、中型和小型之分,发育部位及石油地质特点存在很大差别的问题。研究了走滑断裂与油气成藏关系,认为:大型走滑断裂带是油气富集地带,沿线一般发育有走滑盆地。走滑盆地具有沉积速度快等沉积特点,利于有机质的保存和优质储层的发育。走滑断裂活动可形成雁列、花状等一系列典型的伴生构造,这些构造往往紧邻生油凹陷,并且经断裂与烃源岩相通,是良好的油气圈闭。走滑断裂不但可以形成利于油气成藏的静态要素,而且走滑活动还利于生油母质向油气转化、可改善储层物性、利于油气的排出和运移。

Abstract:

Strike slip motions are general structural events on the earth,and can be classified into large,middle and small scale.There are great differences among them in

developing position and characteristic of petroleum geology.Along the large scale strikeslip faults,which are rich in hydrocarbon accumulation,many strikeslip

basins develop.The feature of fast depositing in strikeslip basin makes organic matter easily be preserved and good reservoir beds form.Strikeslip fault can also

lead to a series of echelon and flowerlike structures,which are typical associated structure of the faults.Closing up to petroleum generative depression and

interlinked with source rock by the faults,these associated structures can be good traps for hydrocarbon.The strike slip motion can not only form the static state elements

for hydrocarbon accumulation,but also favorable for hydrocarbon generation,improving reservoir physical property and hydrocarbon migration.

Key words: strikeslip structure, basin, deposit, hydrocarbon accumulation, hydrocarbon reservoir formation
