Abstract

The tyumen formation is a low-permeability object with a complex geology. The reaction of production wells to the RPM system in such conditions is less pronounced than in traditional reservoirs. In connection, the question often arises about the efficiency of drilling additional injection wells in an in-line development system (link wells).

As part of the work, a sector of hydrodynamic model was created. Model calculations were made for performed to assess the effect of drilling nodal injection wells. In addition, without those stagnant zones are formed, the reserves of which are not developed.

A method for assessing the feasibility of drilling nodal directional injection wells using a hydrodynamic model is proposed.

Key words:

Jurassic sediments, Tyumen Formation, hard-to-recover oil reserves, low-permeability reservoir, horizontal wells with multi-stage hydraulic fracturing (horizontal wells with multistage hydraulic fracturing), the efficiency of the RPM system, link wells, assessing the effectiveness of drilling link wells, the effectiveness of the development system, Rosneft Oil Company
