With the development of geophysical prospecting, especially to meet the needs of high-precision prospecting, high-density acquisition, broadband acquisition, single-point acquisition and low-cost acquisition. The parameters of seismic geophone data should be added to the parameters of the geophone, including but not limited to. Develop displacement geophones, add new performance indicators, perform some physical inspections on […]

Shallow seismic exploration is an engineering geological and geophysical exploration that uses the characteristics of seismic wave propagation in different rocks and soils to detect shallow geological structures (usually tens to hundreds of meters) and determine the physical and mechanical parameters of rock and soil. As per different tasks, purposes and different geological conditions, different […]

The development direction of seismic geophone of broadening the frequency revolves around how to obtain lower frequency and higher frequency components.

The Schlumberger array is an array where four electrodes are placed in a line around a common midpoint. The two outer electrodes, A and B, are current electrodes, and the two inner electrodes, M and N, are potential electrodes placed close together.   Electrode arrays are different arrangements of electrodes used to perform geophysical resistivity […]

Passive seismic is detection of natural low frequency earth movements, with the purpose of discerning geological structure and locate underground resources.

How are seismic technologies used in finding oil and gas today?What we use in exploring Earth’s energy resources is called reflection seismology.

I. Q: What is Seismic Survey? A: The seismic survey is one form of a geophysical survey that aims at measuring the earth’s (geo-) properties by means of physical (-physics) principles such as magnetic, electric, gravitational, thermal, and elastic theories. It is based on the theory of elasticity and therefore tries to deduce elastic properties […]

P wave is body waves that propagate through the planet. P-waves travel 60% faster than S-waves on average because the interior of the Earth does not react the same way to both of them.   P-waves are compression waves that apply a force in the direction of propagation. As the interior of the Earth is […]

Seismic refraction is a geophysical principle governed by Snell’s Law. Used in the fields of engineering geology, geotechnical engineering and exploration geophysics.

What is a hydrophone?   A piezo hydrophone is a kind of underwater microphone designed to monitor underwater noise. A typical peizo hydrophone works by detecting pressure changes in the surrounding environment and converting sound waves into voltage. The speed and distance of the sound wave propagating in the water is proportional to the pressure […]
