MODELING AND PROVING OF DESIGN SOLUTIONS FOR THE RECONSTRUCTION OF TREATMENT FACILITY OF OIL AND WATER

Abstract

The problem with preparing high-quality petroleum products is that it produces water for reuse and injection into the reservoir under conditions of limited facility capacity. This is a relevant issue in the oil and gas sector. Thus, the objective of this research was to develop an approach to justify project decisions during the reconstruction of the Preliminary Water Discharge Unit. The article considers the issue of modeling design solutions for the restoration of the preliminary water discharge unit (Perm region) with a mobile unit. The main industrial tasks are to reduce the water cut of the product and the volume of ballast pumping in the Oil Preparation Unit (OPU) to provide the quality of the background water for injection in the formation meeting the requirements of the industrial standard. The mobile installation is an innovative development and has all the necessary equipment to recreate the production process of the preparation of well products on a scale of approximately 1: 100. The results of the simulation of the well production process showed that it could be achieved 1 % with heating at 30°C in the injection of demulsifiers SNPH-4880, STH-9. The complicated method showed a functional and stable dependence on the temperature and quality indicators of the process in the presence of a demulsifier. During bench tests, values of technical indicators were found that reduced the volume of ballast pumping by an average of 5-6%. Studies of water samples from the outlet of the mobile unit showed the best results when testing the STH-9. The results obtained are of great practical importance, and the method and the special mobile equipment proposed in the article can be used in any oil treatment production plant.
