摘要: 把信息源的分布、信息的录取、信息的再现和信息的再生有机地结合起来,提出并建立了完整的"四维试井"理论体系.运用该理论体系研究了动态监测信息在空间分布上的科学性、合理性,以及试井参数在空间上的分布、延拓及随时间变化的规律.把优化理论应用到信息源的分布上,利用模拟退火算法给出了动态监测系统优化部署的方法,实现了科学布井、经济布井.以黑油模型为基础,建立了考虑层间窜流的多层、多相数值试井理论模型,实现了压力场和含油饱和度的"四维试井理论"分析.把神经网络技术和地质统计学理论应用到"四维试井"理论中,给出了动态监测信息空间分布、空间延拓与时间推移的试井解释方法及动态预测分析方法.

Abstract: Combining the allocation of sources,gathering restructuring and reproducing of information,the "four-dimension well testing" theoretical system was established and used to systematically study allocation of dynamic inspection information in spatial space and analyze the distribution,extrapolation of tested parameters and their change with time.The optimum theory was used to the allocation of information sources.A practical method to obtain optimized dynamic inspection plan was given with the simulated annealing algorithm.A multi-layer and multi-phase four-dimension numerical well testing model was set up on the basis of black oil model.The analysis on pressure and saturation distribution was made with the four-dimension well testing model.The neural network and geo-statistica method were brought into the 4-D well testing theory to realize the extrapolation of dynamic inspection information in the spatial and time space.

Key words: four-dimension well test, pressure inspection, system optimization, numerical well test, time extrapolation well test, space extension well test
