ANALYSIS OF THE EFFICIENCY OF CONDUCTING GEOLOGICAL AND TECHNICAL MEASURES BY MECHANICAL METHODS ON THE KHARYAGINSKOYE FIELD
In the process of oil production, all of the recoverable formation fluid (oil and water) passes through the bottomhole formation zone of the producing wells. These processes occur at temperatures and pressures different from those at which these fluids were originally at the surface or in the formation. As a result, both various hydrocarbon components (resins, asphaltenes, paraffins, etc.) and various salts precipitating from solutions as a result of thermodynamic equilibrium disturbance can be deposited in the bottomhole formation zone, as in a filter. Clogging of the bottomhole formation zone is one of the urgent problems that arise during the operation of wells. Because of this, the inflow of formation fluid into the well is impaired. To stimulate the inflow into the well, various methods are used to influence the bottomhole formation zone, which increase its permeability, and, as a consequence, an increase in the inflow of formation fluid into the well occurs. The article discusses the results of geological and technical measures on the Kharyaginskoye field by mechanical methods, which include hydraulic fracturing and well reperforation. Performance indicators are compared, key issues identified and recommendations made.
