The article discusses the problems associated with metrological support of equipment for geophysical research, issues of ensuring the uniformity of well measurements, the creation of Russian standards for calibrating well equipment when determining the porosity coefficients and oil, gas, water saturation, determining the parameters of defects during well cementing and technical condition of casing strings and the water-oil-gas flow. The problems of creating full-fledged methods for measuring the parameters of oil and gas fields with conventional and hard-to-recover reserves have been investigated. The key directions of development of the Russian metrological support of geophysical well measurements were determined. The tasks that need to be solved to create metrological support for geophysical well logging as an industry that meet international standards are indicated. The expediency of creating a Russian Geophysical Center for Metrology and Certification, the need to develop a new and update the existing regulatory framework, which will allow Russian geophysics to reach the level of world leaders in the field of geophysical research, are substantiated.
The article discusses the method of numerical modeling of a functioning reservoir based on the oil recovery hydromechanics model in the hyperbolic Cauchy problem. Optimization results for reservoir formation channels (RFC) modeling reveal integer values of new models with linear parameters of hydro-resistance, piezo capacitances and piezo inductances in the dimensionless values. The solution result is an effective tool for current prediction of filtration capacity properties (FCP) of the reservoir in the elastic water-pressure mode. The deduced numerical simulation methods based on long-term reactive RFC resistances make it possible to specify the limits of quality of oil displacement with controlled excitations at its coordinate-discontinuous controls.
The article discusses a direction for improvement of the oil recovery stability simulation method. It is shown that the problem of stable productive layer development is solved by setting appropriate goals. To solve the first task, it is necessary to substantiate RFC plugging in the hard mode. The main calculated ratio is the modified Dupuis-Forchheimer and Bernoulli equations based on linear hydraulic resistances of the RFC. To solve the second task, it is necessary to substantiate the choice of resonant frequencies of the oil recovery process in the elastic water-pressure mode. The dependences allow us to distinguish the upper and lower limiting frequencies of the stable oil displacement mode. The solutions make it possible to isolate main conclusions in a complex form.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
