Abstract

This article implements the implementation of regression analysis at one of the operational facilities of the Lower Cretaceous complex. With the help of statistical analyzes implemented in the system of geological and technological measures, the effectiveness of the selected methods of influence on the formation is evaluated. This approach allows minimizing diminishing oil and gas producing enterprises when forecasting geological and technical measures (GTM), by selecting wells to obtain objects, taking into account the satisfaction of the regression model obtained during the calculations. Using statistical modeling, the duration of the effect of geological and technical measures was calculated, as well as the specific technological effect. The object of study is in the Kogalym region, located at the northern end of the Surgut and Nizhnevartovsk vaults. Changes in the geological and geophysical parameters of the reservoir, varying degrees of oil production and the effectiveness of the application of methods of influence on the reservoir. The strata examine the object, the complexity of which consists of sandy-silty differences in detrital rocks. For the object under study, an analysis of geological and technological measures was carried out. The sequence of stages in creating regression models: a composite matrix consisting of geological and technological indicators of operational objects, correlation input data, obtained geological and statistical dependencies after geological and technological measures, the characteristic of the insurance companies that provide the greatest efficiency of the considered geological and technical measures for this object.

Key words:

field; regression analysis; oil recovery; equation; geological and statistical dependencies; influence; geological and technical measures; hydraulic fracturing; bottomhole treatment; filtration-capacitive properties.
