UTILIZATION OF BALLAST WATER PRODUCED ALONG THE WAY USING THE TECHNOLOGY OF WELL SEPARATION OF OIL-WATER EMULSIONS

Abstract

The relevance. One of the main problems of the oil and gas industry in the field of oil and gas production is the production of large volumes of ballast water. The average multiplicity of pumped water to oil can be 4:1 or more. On the territory of the Perm region, this problem is particularly urgent, since many fields are at the 3rd and 4th stages of development and require the introduction of new technologies for more profitable oil production. Due to the pumping of large volumes of liquid, the equipment is worn faster and additional energy costs for its use appear. In this regard, the introduction of technology for well and cluster separation of oil-water emulsion is one of the most effective ways to solve the production problem, by decentralizing the system for collecting and preparing well products. Objects:well bushes with an average water cut of 65–70% or more. Methods: simulation of the cluster separation process in Aspen HYSYS; laboratory studies on the created layout that simulates a well. Results. This paper presents the technology of cluster separation of well products for oil and water with further use of simultaneously produced water in the system of reservoir pressure maintenance. The technological scheme of the installation is presented. Laboratory tests were carried out and the optimal parameters of its operation were identified. The technical and economic assessment of the technology implementation and justified technical solutions are given.
