断裂密集带在上生下储油运聚成藏中的作用——以松辽盆地三肇凹陷扶杨油层为例
|
摘要
为了认识断裂密集带在三肇凹陷扶杨油层油聚集成藏中的作用,利用地震解释结果对断裂密集带的发育和成因进行了研究,得到三肇凹陷扶杨油层发育有大量T2断裂,这些T2断裂在平面上呈35个密集带分布。它们主要是由基底活动、斜拉调整和火山口分布控制形成的。通过油藏解剖及油成藏条件空间匹配关系研究,得到三肇凹陷扶杨油层油成藏模式:青一段源岩生成的油在其内超压作用下沿着断裂密集带边界断裂向下伏扶杨油层中运移,再在浮力作用下向断裂密集带两侧扶杨油层侧向运移,在地垒构造上的断块或断层-岩性圈闭中聚集成藏。通过断裂密集带与油分布关系研究,得到断裂密集带对扶杨油层运移成藏有4个方面的控制作用:①断裂密集带两侧是油聚集的有利地区;②断裂密集带附近,扶杨油层距青一段源岩底面越近的油层,油越富集;③断裂密集带两侧地垒构造是油聚集的主要场所;④距断裂密集带边界断裂越近,油井产能越高。
To understand the effect of fault condensed belts on oil migration and accumulation of F,Y oil layer in Sanzhao depression,the development and genesis of fault condensed belts were studied by using seismic interpretation results.The development of a number of T2 faults was discovered in F,Y oil layer of Sanzhao depression.These T2 faults were distributed in 35 fault condensed belts in horizontal plane.They were formed by the control action of basement action,regulation with oblique extension and distribution of volcanic mouth.By anatomy of oil reservoirs and study of space match relation between oil reservoirs and accumulation conditions,it was discovered that oil accumulation model of F,Y oil layer in Sanzhao depression was that the oil from K1q1nsource rock migrated down to F,Y oil layer through boundary faults of fault condensed belts under the action of overpressure and migrated laterally to two sides of fault condensed belts under the action of buoyancy,at last,accumulating in fault blocks or fault-lithology traps on horst structure architecture.By the study of space match relation between fault condensed belts and oil distribution,four control actions of fault condensed belts were discovered in oil migration and accumulation of F,Y oil layer:①Two sides of fault condensed belts were favorable areas for oil to accumulate;②The nearer is the F,Y oil layer from bottom of K1q1 n source rock the more abundant is the oil accumulation in vicinity of fault condensed belts;③Horst structures of two sides of fault condensed belts were favorable places for oil to accumulate;④The nearer distance from boundary faults of fault condensed belts,the higher productivity of oil well is.
