Method and device for determining rock mineral content coefficient and storage medium

Abstract

The invention discloses a method and device for determining a rock mineral content coefficient, a storage medium and computer equipment, and the method for determining the rock mineral content coefficient comprises the following steps: for each mineral forming a rock, constructing a relational expression according to the pre-measured molar mass of the mineral and a pre-determined molecular formula model; solving the relational expression to obtain a distribution coefficient of the main element; judging whether the calculated distribution coefficient of the main element meets a preset condition or not; if so, calculating the content coefficient of each element forming the mineral in the mineral according to a molecular formula corresponding to the distribution coefficient of the main element; and determining a content coefficient of each element in each mineral forming the rock in the mineral and a coefficient matrix of the relationship between the elements in the rock and the mineral. The method can effectively determine the quantitative relationship between the mineral content and the element of the igneous rock, and provides a theoretical basis for identifying the mineral type and the mass content of the igneous rock stratum.

Description

technical field [0001] The invention belongs to the technical field of petroleum exploration, development and application, and particularly relates to a method and device for determining a rock mineral content coefficient, a storage medium and computer equipment. Background technique [0002] Jin Yunzhi, Gao Chuqiao, et al. (2018) established a relationship model between igneous rock formation element logging data and various lithologies on the basis of formation component analysis; Starting from the content of H, Si, S, Ti and other formation elements, quantitatively calculate the content of igneous rock lithological components. CN107194401A is based on the standard grayscale charts of igneous rock QAPF, etc., through the links of igneous rock mineral composition input point, input point position gray value acquisition, and quick acquisition of igneous rock name based on hash table collection, etc., to quickly realize automatic classification and naming of igneous rocks.
