HIGH PERFORMANCE WATER TREATMENT TECHNOLOGY FOR THE RESERVOIR PRESSURE MAINTENANCE AT OIL FIELDS

Abstract

This article considers the problem of deterioration of permeability of reservoirs in the bottom-hole zone, as well as the problem of decrease of water intake capacity of water injection wells due to colmatation of pores and channels of the productive reservoir by the suspended solid particles that are present in water, which is injected in order to maintain the reservoir pressure. Author of this article has performed monitoring of corrosion, as well as supervision over the composition of injected water and analysis of mechanical impurities in the injected water at "Kumkol" oilfield, as well as at "Aryskum" and "Uzen" oil-fields. In addition, this article presents characteristics of the firm wells and analysis of dynamics of the main parameters from the very beginning of development of these wells. During preparation stage of this investigation, the author of this article has received the process patent on the method of deep cleaning of the reservoir waste waters, which contains suspended solid particles. The main task and technical result of this invention is to increase efficiency of treatment of field wastewater and produced waters, which contains suspended solid particles. The Author has proposed new method of deep treatment of the produced waters, which ensures capture of suspended solid particles.
