喇嘛甸油田南中东一区经过多年的勘探开发,较大幅度的构造油藏已经开发殆尽,进入了特高含水阶段.为达到高效开发的目的,就必须对剩余油进行更精细的预测.分析研究该区的萨Ⅰ反射层微幅度构造的成因、分类和特征,并利用地震、测井等资料,采用趋势面分析、等时切片、相干体及井点数据小网格成图等技术手段对微幅度构造圈闭进行识别和探索,形成了一套具有针对性的技术方法.对剩余油的注采开发具有指导作用,对油气田老区的滚动勘探开发具有重要意义.%The first district of eastern south central block in Lamadian oilfield has been explored for many years, structure reservoirs of big amplitude has been hardly explored completely, which has entered the period of a high water stage. To accomplish the purpose of highly efficient exploration, oil remaining must be anticipated more accurately. The cause, classification and characteristic of tiny amplitude structure of Sa I reflector in this area is analyzed. With seismic and log data, using technologies of analysis of tendency surface, time-slice map, correlation cube and small gridding map of well data, reservoir of tiny amplitude structure is recognized and detected. An aimed technology method is formed, which plays guidance role in the injection and production development of the remaining oil and important significance to rolling exploration in old oil and gas area.
