基于聚类差异分析的边底水气藏产水预测新方法
A New Method of Predicting Water Production in Gas Reservoirs with Edge and Bottom Water Based on Clustering Difference Analysis
摘要
Abstract
The production practices of many gas reservoirs with edge and bottom water in China and other countries indicate that the water/gas ratios predicted by conventional numerical modeling method in designing overall development plans are usually lower than the water/gas ratios in actual production of gas fields.In view of this problem, a new method of predicting water production based on clustering difference analysis was advanced.This new method was applied in clustering analysis of the water breakthrough regularity of the study targets, so as to analyze the major differential factors between the study targets and the analogy targets;by displacing the major differential factors in numerical modeling, the water breakthrough regularity of the above two types of targets was quantified.Finally, water production was predicted by numerical modeling fitting.By verifying the new model using the production data of the Yacheng D gas field, the water breakthrough time that was predicted by this new method and the variation relation curve between water/gas ratio and recovery degree have higher coincidence with the actual production situation.The study result can effectively solve the problem that water production is hard to be predicted in Lingshui A deep-water gas field, and this method can be applied in other gas reservoirs with edge and bottom water.关键词
