IMPROVEMENT OF DEVELOPMENT OF UDMURTIAN FIELDS BY THE SYSTEM OF HORIZONTAL WELLS WITH MULTISTAGE HYDRAULIC FRACTURING

 

Annotation. In view of the deterioration of the structure of reserves at the fields of Udmurtia the tendency of oil production decrease is observed. In the article, the problems of development of carbonate reservoirs of Udmurtia are considered on the example of Vereya-Bashkirian deposits of one of the fields. Carbonate reservoirs are characterized by uneven development of reserves: zones with high permeability are developed faster and more completely, and zones with low permeability remain uncovered by the development process. As a solution, the introduction of horizontal wells with multistage hydraulic fracturing in areas with low natural productivity is proposed. On the basis of multivariate modeling, optimal parameters of the development system were selected: distance between wells, length of horizontal section, number of hydraulic fractures. The system of horizontal wells with multistage hydraulic fracturing in the areas with low permeability and porosity will allow one to increase the annual oil production of the object.

Keywords: multistage hydraulic fracturing, designing of development system, horizontal wells, Middle Carboniferous sediments, carbonate reservoir.
