摘要:
杨大城子油层现已成为松辽盆地南部油气勘探的重点层位之一。杨大城子油层油藏围绕T2断裂密集带分布,关于断裂密集带如何控制油气运移,什么样式的断裂密集带有利于油气聚集,断裂密集带什么部位有利于油气富集等问题还没有形成统一的认识。通过地震和构造资料总结断裂密集带平、剖面特征,扶新隆起带杨大城子油层主要发育4种断裂密集带,即反向断阶带、反向断阶 ̄地堑 ̄反向断阶带、反式断阶 ̄地堑 ̄顺向断阶带、反式断阶 ̄地堑 ̄地垒带。当断裂密集带与砂体方向大角度相交时,易形成岩性 ̄断层圈闭,断裂密集带两侧的地垒和反向断阶是油气聚集的有利场所;当断裂密集带与砂体方向近平行时,断裂带主要起油气疏导作用。
Abstract:
Yangdachengzi oil layer has become one of the key exploration horizons in southern Songliao Basin in recent years. However, the reservoirs of Yangdachengzi oil layer distribute around T2 fault-intensive zone. There is no unified understanding on how the fault-intensive zone controls the oil and gas migration, what type of fault-intensive zone is beneficial to oil and gas accumulation, and what part of fault-intensive zone is conducive to hydrocarbon accumulation. Based on seismic and structural data, the horizontal and profile characteristics of the fault-intensive zone are summarized. Four types of fault-intensive zones are mainly developed in the Yangdachengzi oil layer, Fuxin Uplift: antithetic fault terrace belt, antithetic fault terrace-graben-antithetic fault terrace belt, antithetic fault terrace-graben-consequent fault terrace belt, and antithetic fault terrace-graben-horst belt. When fault-intensive zone intersects with sand body direction at a large angle, lithology-fault trap is easily formed; the horsts and antithetic fault terraces on both sides of the fault-intensive zone are favorable places for hydrocarbon accumulation. When fault-intensive zone is nearly parallel to sand body direction, fault zone plays a major role in guiding oil and gas.
