Estimates of Fracture and Permeability of Rocks in Well Sections According to the Predicting Method

Abstract

The article is devoted to highlighting the methods of studying the petrophysical characteristics of rocks using the developed theoretical-empirical method for predicting the oil and gas capacity of well sections and their results. As a part of the predictive method, methods for determining a number of important petrophysical characteristics of rocks in well sections were additionally developed. In particular, cracking and permeability of rocks is estimated by the indicator of crack opening – the Qside parameter, the strength of rocks is estimated by volume density and velocities of elastic bulk waves, and the types of rocks in layers are determined by a set of petrophysical parameters, including the density of the solid phase of rocks. The determining results of these parameters in sections for wells 4-North-Zarichnyans'ka and 1-Lishchyns'ka, are given.
