三维地质建模方法在复杂断块油气藏研究中的应用
|
摘要
断块油气藏断层发育,构造复杂,应用确定性地质建模技术可实现构造模型的三维可视化.通过对油气藏顶底层面断层线的精确编辑,实现油气藏内部断层之间复杂的切割关系,从而形成油气藏精确构造模型,解决了内部被多条断层切割的复杂油气藏构造建模研究过程中回避内部断层的缺陷.该技术可以建立油气藏精确构造模型,并在梨树断陷河山地区地震反演的应用中取得了较好的效果.
The definiteness geological modeling of reservoirs,which are transected by interior faults,is applied to achieve 3D visualization of tectonic model.With precise edition for fault lines at the top and bottom of reservoir,the complicated transecting relation between the interior faults is realized to form the precise structure model of reservoir.The model solves the problems during the complicated reservoir structure modeling,in which the interior faults are avoided.This technology is applied to the seismic inversion in Heshan area of Lishu fault depression and shows a good result.
