STATISTICAL INTENSITY OF TRANSFORMATION PROCESSES OF OPEN GEOLOGICAL SYSTEMS BASED ON GEOPHYSICAL DATA

Abstract

The article provides a theoretical justification for the parameter of statistical intensity of transformation processes of open systems consisting of elements and the illustration of empirical confirmation of this parameter validity. Under the influence of external dynamic flow on the elements of open system, the process of their transformation takes place. The correlation between independent characteristics of these elements may be due to the dominant process of influencing the system. The product of approximation coefficient and statistical interval parameter of two samples of measured characteristics corresponds to the statistical intensity of the open system transformation process. The process of secondary kaolinitization is investigated, its intensity is determined by positive correlation relationships of geophysical (petrophysical) indications of the total porosity and clay content of sand rocks at various oil-and-gas fields. The positive regression between samples of petrophysical parameters of porosity and clayiness is interpreted as a secondary kaolinitization of sandy rock, and the product of approximation coefficient with a part of the studied interval of this positive correlation of sample values is defined as the statistical intensity of the secondary kaolinitization process. The validity of the method used is confirmed by comparing the calculated intensity of secondary kaolinitization of the studied interval with the petrographic study of core sections.
