摘    要:将柴达木盆地内第三系沉积岩分布区用10km×10km的网络覆盖,得到703个数据采集网点.每个网点输入地层结构、泥质岩百分比和地表热流作为模拟的初始参数,应用网络式盆地模拟软件,对沉积埋藏史(B)、地层受热史(T)和油气成熟史(M)进行同步模拟(简称B-T-M模拟).B-T-M软件具模块式嵌装结构,可直接给出模拟结果的图形输出,包括:1.单个网点的三史演化图;2.任意走向的二维发展剖面图;3.网点覆盖区内的二维平面分析图件.这些分析图件结合生油岩系的有机质丰度条件,成功地对全盆地的油气资源远景进行了分区预测.

关 键 词:柴达木盆地   网络式盆地模拟   B-T-M软件   油气远景预测

Abstract:The area of distribution of Tertiary sedimentary rocks in Caidam Basin is covered by a 10km×10km network producing 703 mesh points for data read-in.Stratigraphic column,percentage of mudy rocks in the column and surface heat flow are read-in to each mesh point as initial parameters for simulation.A network basin simulation software is developed for synchronously modelling the burial(B),thermal(T)and oil-gas maturation(M)histories,which is abbreviated as B-T-M simulation.And the software is also named as B-T-M.The software has a structure of flexible assemblage and combination being able to output directly the graphic forms of the simulation results including:(1) B-T-M evolution graph of each single mesh point;(2)2D developing cross-sections in any desired direction;and(3)2D analytical planar maps in the network coverage area such as distribution map of oilgas maturation degrees,map of total thickness of oil-and gas-window,distribution map of threshold depth for initial oil maturation etc.These analytical maps combined with the abundance of organic matters of oil-source rocks have been successfully used for district-divided prediction of oil-gas resource prospects of the whole basin.
Keywords:Caidam Basin  Network basin simulation  B-T-M software  Oilgas prospect prediction
