摘要
该文以塔河地区三叠系中油组为例,通过地震相分析,探讨了不同地震相相应的沉积特征,认为中-强振幅连续反射地震相主要是辫状三角洲平原的沉积特征响应,中等振幅断续反射地震相主要是辫状三角洲前缘的沉积特征响应,弱-空白反射地震相多代表以泥岩沉积为主的滨浅湖(或间湾)相,在此基础上确定沉积相带的展布,结合构造背景,指出岩性圈闭可能发育的主要地带.
Abstract
According to seismic phase analysis,the corresponding sedimentary characteristics were studied.The medium-strong amplitude of continuous seismic phase indicates braided deltaic plain deposition,medium amplitude of interrupted seismic phase suggests depositional facies of braided deltaic front,and weak or gap seismic phase means mudstones deposited in shallow lake(or interdistributary bay).On basis of above relationship between seismic phase and depositional facies,distribution of sedimentary facies of the Triassic in Tahe area was discriminated,in accordance with its structural setting the potential lithological traps were indicated.
