Evaluation Of The Effect Of Water Injection Fuchang Oil Area

Evaluation of the effect of water flooding reservoir, always runs through the whole process of oil field water injection development.The purpose of evaluation of water flooding effect, finds out the factors affecting development result,analysis of the existing problems,clear oil potential,study tapping technology, make corresponding measures,carry out comprehensive adjustment, improve development effect. Reservoirwith low permeability, low permeability, long-term since use natural energydevelopment, measures to increase production but also to the reservoir fracturing reformation as the main means, fracturing of oil wells is too frequent, althoughfracturing after the obvious effect of increasing yield, but the formation pressure drops too fast,the yield decreased significantly.Water injection well injection has been voted 5 to8 years,Chang2 oil-bearing formation has been in rapid yield decline, rapidly risingstage of comprehensive water content.This topic research content is Do the water flooding effect evaluation region to find out the changes of oil reservoir production and pressure and water content, Dynamic analysis of single well and well group, stimulation effect analysis and research, to block water cut rising status, the main effect of water drive index evaluation and the water injection well group waterflood development effect evaluation. According to the Wells in well group by effect, is divided into four types: one-way main effect, the fan main effect, the linear main effect and circular main effect. in order to ensure the oil“note good water,Injection enough water, fine water flooding, effective injection”.
