A comprehensive approach to the analysis of realizing flooding system and its improvement

UDK: УДК 622.276.43

Key words: oil, deposit, flooding system, reservoir pressure maintenance system, flooding system analysis

Authors: A.A. Ankudinov, L.A. Vaganov (KogalymNIPIneft Branch LUKOIL-Engineering LLC in Tyumen, RF, Tyumen), S.K. Sokhoshko (Tyumen Industrial University, RF, Tyumen)

The unified approach to the analysis of the impact of realizing flooding system on the energy state of the reservoir, as well as on the process of development of reserves is suggested on the basis of generalization of existing experience and selection of the most effective tools, used in various departments of KogalymNIPIneft Branch of LUKOIL-Engineering LLC in Tyumen. The proposed approach includes the following steps: 1) the collection and preparation of raw data (technological parameters of wells operation, instrumental measurements of reservoir pressure and dynamic level, the results of hydrodynamic studies, etc.); 2) evaluation of the stimulation intensity; 3) estimation of the dynamics of technological parameters; 4) analysis of the energy state of the formation (voidage replacement, reservoir pressure dynamics). All additional calculations are performed with Microsoft Excel software, without the involvement of geological and hydrodynamic modeling, that significantly reduces labor costs.

Applying the approach is considered by the example of YuV₁ formation. In accordance with the technological parameters of the wells performance, and also with additionally obtained in the analyzing process data, the recommendations for the improvement of the development process and program of geological and technical measures are produced.
