The Method To Explore The Sandstone Matrix Acidizing And The Application Of The Management System

With China’s continuous investment in low permeability reservoir development,the reservoir acidizing transformation technology increasingly demanding. Based on the needs of the general field acid produced, respectively, from the reservoir lithology, physical characteristics, fluid characteristics and other factors, using a microscope, scanning electron microscopy and X-ray diffraction techniques, in close connection with reality, analyzed and summarized in the reservoir damage and acidification success and failure on the basis of the reasons put forward acidification step to success.Under the above conditions, in order to improve the efficiency of oil production acidification, acidification oil production according to need, the authors make use of the current relatively simple and practical VB language, written in a sandstone matrix acidizing management system. The system chosen by the user function module information and intellectual property protection module, acidizing fluid system, acidizing fluid additive selection function to determine the amount of acidizing fluid module, and acidizing process dynamic supervision module. The system is based on multivariate acidizing process, to meet the needs of daily oil production of acidified, and Dawangzhuang Oilfield in Huabei Oilfield A23 wells have been successfully applied.
