Sludge settling pound earthquake exploration method

Abstract

The invention provides a sludge settling pound earthquake exploration method. The method includes the following steps: surveying earth surface types of a sludge settling pound, selecting a geophone according to the earth surface types of the sludge settling pound, assuring a set position of the geophone, assuring a arrangement manner of electric cables, arranging the electric cables according to the arrangement manner of the electric cables, settling the geophone in the sludge settling pound according to the set position, manufacturing artificial seismic waves, using the geophone to pick up the artificial seismic waves, and using the electric cables to transmit a detecting result of the geophone. The sludge settling pound earthquake exploration method is low in cost, easy to achieve, obvious in effects, and the problem that a large area of swamp areas, sludge areas and settling pounds can conduct earthquake exploration receiving can be solved effectively, so the sludge settling pound earthquake exploration method is worthy of popularizing and using.

Description

technical field [0001] The invention relates to the technical field of petroleum geophysical exploration, in particular to a method for seismic exploration of a sludge sedimentation tank. Background technique [0002] Seismic exploration is one of the most commonly used oil exploration methods at present. Its basic principle is to use artificial earthquakes to generate vibration signals in the formation, and according to the design requirements, arrange seismometers to receive vibration signals at different distances from the excitation point, and then analyze the received vibration signals. Perform processing and interpretation, and analyze the properties of formations at different depths, the shape of structures, etc. according to the frequency, amplitude, and velocity of the signal, so as to preliminarily judge whether there is oil generation and oil storage conditions, and finally provide drilling well positions. [0003] When carrying out seismic exploration in shallow ...

AI Technical Summary

Problems solved by technology

[0005] Since the geological characteristics of the sludge sedimentation tank are different from those of the conventional surface, if this type of surface is covered in the seismic survey, it will bring many difficult problems to the construction work, such as the reception of seismic wave excitation, etc. are not ideal; but because of this The land-like surface occupies a relatively large area (as few as dozens of square meters, as many as nearly a hundred square meters), and basically cannot be crossed. If it is crossed, it will also affect the overall contiguousness of the large three-dimensional block and the regional exploration process. Therefore, how to deal with Seismic exploration of this type of surface is a technical problem that needs to be solved urgently in the industry
