松辽盆地双城地区断砂匹配关系与油气优势输导通道
|
摘要
双城地区是松辽盆地一个小型的独立生烃凹陷,油水关系复杂,通过对其生烃能力、砂体和断裂匹配关系研究,建立了双城地区优势输导通道。结果表明,双城烃源岩具备一定的生烃能力,断裂和砂体是双城地区油气成藏的主控要素,断裂是作为控制油气运聚方向的主要因素,自源内北西向排出后,在南北向断裂的转折处进入北东向展布的河道摆动带。当砂体与断裂小角度相交时,油气可以沿砂体与断裂面进行横向和垂向运聚,形成有效的断-砂运聚输导网络;当大角度相交时,以遮挡作用为主,构成有效的成藏圈闭区带。由断砂匹配的油气成藏模式可知王府凹陷北坡是主要勘探方向。
Shuangcheng area is a small independent hydrocarbon-generating sag in Songliao Basin,with complex oil-water relationship. The dominant migration pathways in Shuangcheng area are established based on the matching relationship among the hydrocarbon generation capacity,sand bodies and faults. The results show that the source rocks of Shuangcheng area have certain hydrocarbon generating capacity,and the main controlling factors for hydrocarbon accumulation are the faults and sand body assemblage. The direction of hydrocarbon migration and accumulation is controlled by faults. The hydrocarbon will get into the NE-trending channel zones through NS-trending faults after the NW-trending faults in the source rocks. When the fault and sand body intersect with small angle,transverse and vertical migration and accumulation of oil and gas occur along sand body and fault surface,and an effective sand body-fault migration and accumulation network can be established. On the contrary,when the fault and sand body intersect with big angle,effective reservoir-trap zones are formed. From oil and gas reservoir formation model with matched sand and faults assemblage,it is indicated that the northern slope of Wangfu depression is the main exploration target.
