Layered Modeling Algorithms and Cases for Different Reservoir Development Stages
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.
