Analysis of the effectiveness of the technological system for the development of the XXIII layer of the Goyt-court

The analysis, development of the XXIII reservoir of the Goyt-Kort field, the choice of the field as a priority object for high-pressure gas injection to enhance oil recovery is well substantiated by the geological and production characteristics of the reservoir, technological features of the developed process and economic needs. The relevance of additional development, restoration and arrangement of the field, study of the current state of the reservoir, conducting research of wells, designing technology and techniques for the process of stimulating the reservoir. The reservoir of the XXIII layer of the Goyt-Kort field is characterized by low permeability, significant heterogeneity and clay content. The process of displacement by water in such conditions is very difficult, and therefore attempts to master the injection of water into the XXIII reservoir were unsuccessful. The active mode of injection of compressed hydrocarbon gas into the reservoir has been carried out for more than twelve years and during this time about one and a half billion cubic meters of gas have been injected into the reservoir. The main oil production at the field is currently carried out from the XXIII layer. The field tested and implemented the technology of continuous injection of the inhibitor into the annulus of the well. 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.
