Resistivity sounding data processing interpretation and drawing method

Abstract

The invention belongs to the field of resistivity sounding explanation, and particularly discloses an explanation and drawing method for resistivity sounding, which comprises the following steps of: sorting and preparing data; drawing a resistivity curve; judging the type according to the resistivity curve form; the electrical layer resistivity and thickness are given according to the resistivity curve type; running a program, and calculating a T function fitting error; storing a calculation result in the program; drawing a profile contour section diagram according to a calculation result; and drawing a geological cross-section diagram and the like. When the method is used for explaining resistivity sounding data and drawing a map, the method has the following advantages: 1, the method is simple and convenient to operate; 2, through T function fitting, an interpretation result is closer to reality; and 3, the interpretation software can provide more convenience for data processing and interpretation of grassroots geophysical prospecting technicians. The method is suitable for data interpretation and mapping of the resistivity sounding method, and provides meaningful guidance for field production.

Description

technical field [0001] The invention relates to the field of data interpretation and drawing of resistivity sounding, and specifically discloses an interpretation and drawing method of resistivity sounding. Background technique [0002] The time-domain resistivity sounding method is more and more applied in production, and has achieved good prospecting results. However, how to process and interpret the resistivity sounding data has always been a difficult problem for grassroots geophysical prospecting workers. In fact, this problem has already been solved in our country’s colleges and universities. It’s just that the grass-roots work units have poor information communication or economic problems, and the research results of various universities have not been applied to most grass-roots work units. In addition, with the continuous advancement of science and technology, the frequency domain electromagnetic sounding method is also widely used, especially in recent years, variou...

[0002] The time-domain resistivity sounding method is more and more applied in production, and has achieved good prospecting results. However, how to process and interpret the resistivity sounding data has always been a difficult problem for grassroots geophysical prospecting workers. In fact, this problem has already been solved in our country’s colleges and universities. It’s just that the grass-roots work units have poor information communication or economic problems. The research results of various universities have not been applied to most grass-roots work units.

In addition, with the continuous advancement of science and technology, the frequency domain electromagnetic sounding method is also widely used, especially in recent years, various units have purchased V8, EH4 and other foreign advanced electromagnetic sounding equipment, limited by economic and technical constraints, the frequency Many domain electromagnetic sounding data stay in the data processing stage, but have not reached the level of quantitative interpretation
