| 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．

| 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. |
