Improving the efficiency of exploration and development of oil and gas fields in the conditions of frequently interbedding rocks

Abstract

Abstract Exploration and development of mineral deposits largely affects the dynamics of development of the oil and gas industry in the country. An important stage in the field development is the design of technologies for constructing wells, and the drilling process itself. The appropriate modes and drilling tools create conditions for the maximum oil recovery. In this paper, based on the analysis of existing well drilling technologies and features of the mining and geological conditions of the fields, the use of a new technological solution is substantiated and recommendations are given for its implementation in the Yuzhno-Priobskoye field. The feature of the Yuzhno-Priobskoye field is frequent interbedding, that is, alternation of some rock layers by others. These layers exhibit different mechanical properties, such as hardness, elasticity, and abrasiveness, which arise certain difficulties in the field exploration and development. The proposed technological solution significantly increases the efficiency of mining and geological operations.
