摘要：为了刻画三角洲前缘水下分流河道与河口坝的三维形态以及构型界面，提出了一种专门用于分流河道和河口坝等构型要素的三维构型建模方法。采用Fluvsim程序中的参数定义模拟的分流河道目标体，同时提出7个参数定义河口坝目标体，并用河道平均发育距离定义河口坝的发育位置。在模拟中将所定义的基本目标体投放到背景相中，以构型单元的定量知识库和井点数据为依据，通过调节目标体的定义参数，采用模拟退火的方法实现条件化。实际模拟检验表明，应用该模型计算得到的模拟结果可以有效地整合构型单元的定量规模以及相比例信息，刻画河口坝的空间形态以及各构型单元之间的拼接关系，符合地质模式，与实际井数据吻合较好。关键词：随机建模方法；河口坝；储层；基于目标；示性点过程；三角洲

Abstract: In order to characterize the 3D configurations and architectural intersurfaces of the distributary channels and mouth bars of the delta front, the 3D achitecture modeling method is developed espacially for the achitectural elements such as distributary channel, mouth bar and so on. With the help of the parameters in Program Fluvsim, the target bodies in the distributary channels are defined. At the same time, seven parameters are presented for the definition of the the target bodies in the mouth bars, and moreover the well-developed mouth-bar locations are de-termined by the average developed distances of the channels. In the process of the simulation, the basic defined tar get bodies are put into the background facieses, taking the quantitative knowledge base and well-point data as the evidences, by means of adjusting the defined parameters of the target bodies and simulation annealing method, the conditioning is realized. The actual simulation and inspection show that the simulated achievements obtained from the model calculation can effectively integrate the quantitative scales of the architectural units and proporation infor-
