摘要
由于油藏不同开发阶段特征及其研究目的不同,三维地质建模中层面建模采取的模拟方法和模型精度均有所区别.从三维地质建模角度出发,将油藏开发划分为油藏评价、新区建产和老区调整3个阶段,通过港东二区五断块层面模拟过程中各种模拟算法分析及筛选,提出了层面模拟时,油藏评价阶段建模采用Kriging算法,网格精度为100 m×100 m×5.0 m;新区建产阶段建模采用Kriging算法或Global B-spline算法,网格精度为50 m×50 m×1.5 m;老区调整阶段建模采用Local B-spline算法或Converging average算法,网格精度为10 m×10 m×0.5 m,使层面模拟结果更符合地质情况及研究需要.
Abstract
The simulation methods and model precision adopted for layered modeling in 3D geological modeling vary with reservoir charac-teristics and research purposes at different development stages.From the perspective of 3D geological modeling,the reservoir development can be divided into three stages:reservoir evaluation,new block development,and existing block adjustment.The layered modeling algo-rithms were analyzed and selected for the 5th fault block in Gangdong district 2.It is proposed that the Kriging algorithm should be used for modeling at the reservoir evaluation stage,with a grid resolution of 100 m×100 m×5.0 m;the Kriging or Global B-spline algorithm should be used for modeling at the new block development stage,with a grid resolution of 50 m×50 m×1.5 m;and the Local B-spline or Converg-ing average algorithm should be used for modeling at the existing block adjustment stage,with a grid resolution of 10 m×10 m×0.5 m.This modeling approach can provide results in more coincidence with actual geological conditions and can meet requirements for reservoir research at each stage.
