Data Processing Method of Well Testing
Abstract
The article presents an analysis of technological schemes for the development of the XXIII layer of the Goyt-Kort field, as a result of which the implementation of measures for high pressure gas injection is proposed. The geological and production characteristics of the reservoir, technological features of the developed process and economic needs justified the choice of the Goyt-Кort field as a priority object for high-pressure gas injection to enhance oil recovery. As a result of the proposed measures, an increase in reservoir pressure was noted in the area of the first row of production wells, an improvement in their performance due to gas injection.The characteristic reasons for the frequent well workovers caused by deposits of asphalt-resin-paraffin substances in equipment, in tubing and flow lines have been identified. Measures are provided to eliminate and combat the listed complications. Thus, the field tested and implemented the technology of constant dosing of the inhibitor into the annulus of the well. Comparative testing of the activity of the reagents was carried out. To remove the clay bridging agent of the pore matrix of high-temperature terrigenous objects, the use of reagents based on boronfluorinehydrogen acid is recommended.
