摘　　要：通过地震地质层位标定,明确了沙三中各反射界面的地震反射特征,并在此基础上通过井震结合的方式对全区层位进行闭合追踪。研究表明,沙三中沉积时期,前积地层结构明显,内部地层厚度变化快。其中:沙三中3砂组沉积时期,地层厚度由南东向北西方向逐渐减薄;沙三中2砂组沉积时期,地层厚度分别由南东向北西和由北东向南西方向逐渐减薄;沙三中1砂组沉积时期,地层厚度由北东向南西方向逐渐减薄。Through the seismic geological horizon calibration,the seismic reflection characteristics of each reflection interface in the middle Es3 strata are determined,and on this basis,the whole area is tracked in a closed manner by means of well-seismic combination.The research shows that the progradation structure was obvious and the inner layer thickness changed rapidly during the middle Es3 sedimentation period.Among them,during the sedimentation period of the middle Es3 Sand Formation,the thickness of the formation gradually decreased from SE to NW;during the sedimentation period of the middle Es32 Sand Formation,the thickness of the strata decreased gradually from SE to NW and from NE to SWt.During the sedimentation period of the middle Es31 Sand Formation,the thickness of the formation decreased gradually from NE to SW.
