辽河油田欢喜岭区块大凌河油层位于辽河断陷西部凹陷西斜坡南端,形成于裂谷深陷期,是深水环境条件下形成的一套浊流沉积物;沉积物表现形式在纵向上有多期性,在横向上有突变性;大致可分为3个砂岩组,自下而上厚度、面积均变小,代表了由强到弱的周期性浊积发育期;油层埋深1150～1540m,含油面积3.2平方公里,石油地质储量654万吨。区内三维地震满覆盖。
The Huanxiling block in the Liaohe Oilfield, located in the southern slope of the western slope of the Liaohe Fault depression, formed in the rift-deep depression and is a set of turbidite sediments formed in the deep-water environment. The sediment manifests itself in the longitudinal direction Multi-period, there is a mutation in the horizontal; roughly divided into three sandstone group, bottom-up thickness, area are smaller, representing the strong to weak periodic turbidimetric development; reservoir depth 1150 ~ 1540m, oil area of 3.2 square kilometers, oil geological reserves of 6540000 tons. Three-dimensional seismic coverage in the area.
