WAYS OF ADJUSTING THE OPTIMALITY OF THE DEVELOPMENT PROCESS OF THE GALA FIELD (THE CASE OF THE KS3-4 HORIZON)

Abstract

The study object was analyzed in the article. It is KS3-4 horizon. It is located in the southeast part of the Gala field. Thickness is 245 m thick, while thickness of its increases towards the Kohna Gala region and reaches 270 m. The KS is divided into 12 objects in the north-western part of the Gala field. Thickness is 8-12 meters. Was identified that the thickness of Kirmaki suite mainly is constant along the area. Despite its long-term exploitation, the KS3-4 horizon still has high potential. The remaining balance reserves are 1.7 million tons, and the remaining recoverable reserves are 250.5 thousand tons. During development process, the production of liquid from the beginning of the development of the object disturbs the balance and turns it into a dynamic system. Against the background of this change, the natural geological and technological parameters characterizing the object also change. Therefore, it is necessary to optimize the values of the regulated parameters in order to increase the production efficiency. Therefore, for regulation of development process in the developed object the Stewhart charts are plotted. By the analysis of study object identified that in order to keep the development system stable, it is possible to optimize the process by bringing the oil production closer to the middle boundary. For this purpose, drilling of production wells and tighten the well network to 14 units is required. The perform rapid fluid extraction advisable.
