Abstract

Abstract: Based on the analysis of 5 experimrntal areas of advanced water injection, adaptability of well well network in thye study area is numerically simulated with the analysis method of balancing between injection and production and by combining theoretical and dunamic analysis of study area. After analyzing the relationship between pressure and number ratio of oil well and water well, between contra output of liquid and number ratio oil well and water well, formation pressure and production fluid index with water absorption and that water percentage of different well network and output degree. The authors clarify the influence of well network on formation pressure, oil producing rate and increase of water percentage. The analysis reveals that formation pressure monotone decrease with the increasing of ration of oil and water well, and that fluid production can be increased by adjusting well
network and there is no clear relationship between well network and increasing in water percentage.

Key words: water injection, theoretical analysis, well network, formation pressure, low permeability reservoir, adaptability analysis
