平原复杂地表采集区震源研究

摘要
随着油田勘探程度的不断深入,地质任务要求越来越高,由寻找构造油气藏向岩性、断块等隐蔽油气藏转变,而地表条件也越来越复杂,对地震采集造成了很大的困难。针对平原复杂地表采集区减震震源和地下震源进行研究,对比不同结构、不同壳体和不同药型的8种震源(钢壳TNT超速聚能延迟震源、钢壳TNT超速聚能震源、钢壳TG50超速聚能震源、塑壳TNT超速聚能震源、塑壳高能超速聚能震源、常规延迟震源、高能常规震源、常规震源)的激发效果,选取最佳的激发方式,取得了明显效果。
With the deepening of the oilfield exploration,the more higher geological tasks were required.The targets were shifted from structural reservoirs to the lithological and fault block reservoirs while the terrene was more and more complicated,it resulted in great difficulties to seismic survey.The research of the delay stack explosion technique and underground source were studied according to the complex terrene acquisition area in the plain.And by comparing with the shooting effect of eight kind of sources from different structures,different shells and different drug types(shell TNT overspeed shaped delay,shell TNT overspeed shape,shell TG50overspeed and shape,plastic shell TNT overspeed and shape,plastic shell high energy and overspeed shape,conventional delay source,high energy conventional source and conventional source),the optimal shooting methods are chosen,and obvious effects are obtained.
