Abstract

The invention discloses a method for calculating the mineral content of a stratum. According to the method, a linear programming mathematical model is obtained, and the mineral content of the stratumis calculated by using a linear programming method. The method of the invention comprises the following steps that: X-ray fluorescence logging / test data are adopted as a constraint condition; a stratum mineral type is adopted as a decision variable; an objective function is constructed for the mineral content of the stratum. According to the method, the X-ray fluorescence logging / test data are utilized; the proper objective function is constructed; the inequality constraint and equality constraint of an element response equation are utilized; the volume content of the stratum is rapidly and accurately is obtained by means of inversion by applying the linear programming method; and therefore, cost and time are saved, and the acceleration of domestic shale stratum exploration and developmentcan be facilitated.

Description

technical field [0001] The invention relates to the field of geological exploration, in particular to a method for calculating the mineral content of formations. Background technique [0002] The types and contents of minerals in strata are of great significance to stratum identification, lithology division, determination of stratum clay content and type, calculation of skeleton parameters and study of depositional environment, etc. [0003] In the prior art, formation mineral content is usually calculated based on well logging data. Well logging, also called geophysical well logging or petroleum well logging, referred to as well logging, is a method of measuring geophysical parameters by using the electrochemical properties, electrical conductivity, acoustic properties, radioactivity and other geophysical properties of rock formations. Generally, well logging is to lower the special logging instrument to the bottom of the well and then pull it up, and collect the logging d...
