三维油藏模型色彩显示

三维油藏模型彩色显示是油藏数值模拟和仿真的一项关键技术．它是在用地质统计方法将原始地质数据转化为网格化的空间数据场后，利用着色、消隐、投射、挖切等可视化手段建立空间几何模型，由此得出能显示物性的立体图、物性区间图、体化栅状图等各种三维油藏地质图件．该技术特征是，对网格内的每一个象素都进行了插值计算和着色，从而避免了锯齿状的物性区间边缘；着色直接利用网格结点的物性值进行，又能够直接反映油藏的真实情况．本法得出的三维油藏图件色彩逼真，描述细致，经胜利测井公司和物探局使用认为技术上有创新，有较高的实用价值．开发环境：在ＳＵＮ工作站上，以Ｘ－Ｗｉｎｄｏｗ和Ｍｏｔｉｆ为平台．

Color Display of 3D Oil Reservoir Model

Color display of 3D oil reservoir model is a key technique to oil reservoir numerial simulation,which is the stereographic map displaying the physical properties of reservoirs,physical property interval map,body fence map,etc. get by transfering original geologic data into mesh spatial geometric model by geologic statistics method. The interpolation calculation and the coloration for every image element point within meshes avoid serrated border of physical property interval. The values of physical parameters at mesh nodal points are used in coloring,which makes the maps directly reflect the true state of reservoirs.The 3D oil reservoir maps get by the method are thought practical after being used by Logging Company of Shengli Oilfield and Geophysical Prospecting Bureau.
