Abstract:By seismic exploration, a Lens was discovered in the south Damintun depression in Liaohe oil field.The maximum thickness of the lens is 2,800 meters,its flanks thinning, The reflection legs from its overburden is domelike,and its velocity is 2,430-2,700 m/s.There is almost no reflection inside the lens.The velocity in the lens is about 2,500m/s,lower than the velocity of country rocks.Its density is 2.22-2.27g/crn3.All these characterize a shale diapire,The Shenyang No, 55 well which is nearby the Lens flank,reveals that its interval corresponding to the shale diapire consists of melanocratic we can infer shale beds with some good intermediate oil sands.Thus that the shale diapire also has oil resource.
