Seismic geology horizon calibrating of Bincan well 1 in Subin depression and its geological significance

CHEN Xiu-yan~(1),LIU Zhao-jun~(1),CHEN Yong-cheng~(1),WANG Shi-hui~(2),YANG Jian-guo~(2)1.College of Earth Sciences,Jilin University,Changchun 130061,Jilin,China; 2.Exploration & Development Research Institute of Daqing Oilfield,Daqing 163472,Heilongjiang,China  
In order to solve efficiently the problem of tracking and closing horizons,the authors calibrated the seismic geological horizon in Bincan well 1 again by analyzing drilling core,logging data,velocity data,attributive profile,synthetic record,etc.Compared with the results calibrated previously,the reflection T_5 of the basement top is changed from 2 100 ms to 1 843 ms;reflection T_(4-2) of Chengzihe Formation top is declined for one seismic phase.According to the new calibration results,the distributions of Suibin Formation and Dongrong Formation are reconsidered as local in nature,but regional;and their thickness probably increased northward.The buried depth of the Chengzihe Formation top is changed in account from 1 692 m to 2 246 m,and correspondingly,the thickness of Chengzihe Formation is also changed in account.
