The Compatibility Studing between Reservoir Physical Property and Acidification Technology

The oil production draw on from improved reservoir was determined by whether the acid formulation used for acidification improvement of reservoir is reasonable.Triturating this kind of acid formulation by identifying reservoir physical property have breaken general oil technological model and increasing heavily the successful rate of acidification.This method have been proved by application in several well and have obtained huge benifits.Basic condition of triturate science acid formulation includes:maintenance of the reservoir construction,coordination of the porosity with permeability,control of the formation differential of presure,prevention of reservoir sensitivity and the compatibility between formation water mineralize rate and the fluid outside the well.
