JZN-1 Natural Gamma-Ray Spectroscopy Probe| Geotech Instrument Co., Ltd.

SXW-3019 Multi-Information Comprehensive Probe

PRODUCT PARAMETERS

The spectrum stabilization is achieved by real-time temperature compensation and monitoring the count rate of the high-energy peak symmetry channel, and the analysis is achieved by the linear matrix least squares method.
The hardware multi-channel buffer solution is used before the high-speed AD to ensure that the instrument is suitable for high-radioactive formations.
It can measure and record continuously or point by point. It greatly improves the work efficiency.

JZN-1 Natural Gamma-Ray Spectroscopy Probe

Abstract

JZN-1 Natural Gamma-Ray Spectroscopy Probe can solve more geological problems by distinguishing the types and enrichment of radionuclides based on natural gamma-ray spectrum logging technology through comprehensive analysis of gamma-ray energy and intensity. The distribution patterns of uranium (U), thorium (Th), and potassium (K) are related to the mineral composition, diagenetic environment, organic matter content, and movement of oil, gas, and water of rocks, and have important geological prospecting significance.

FAQ

In gravity exploration (SI), what is the unit of gravity? How to convert gravity units between SI and CGS?

What are gravitational field and gravitational potential?

What is the normal gravity field of the earth? What are the rules for the change of the normal gravity field with latitude and altitude?

① The normal gravity field of the earth: Assuming that the earth is a rotating ellipsoid (reference plane), the surface is glossy, the internal density is uniform, or it is distributed in concentric layers, the density of each layer is uniform, and the deviation of the shape of the ellipsoid from the geoid is very small, then the gravity field generated by the earth is the normal gravity field.
② The normal gravity value is only related to the latitude, the smallest at the equator and the largest at the poles, with a difference of about 50,000 g.u.; the rate of change of the normal gravity value with latitude is the largest at 45° latitude, and zero at the equator and the poles; the normal gravity value decreases with increasing altitude, and its rate of change is -3.086 g.u.. The main feature of the long-term change is the "westward drift" of the geomagnetic elements, both the dipole field and the non-dipole field drift westward, and have a global nature.
