Problems solved by technology

[0007] Due to the resistance of the metal cable itself, it will cause a certain signal loss to its analog signal. It is difficult to separate the analog signal from the superimposed noise during transmission. The noise will be transmitted and amplified along with the signal, seriously affecting the communication quality. As the transmission distance increases, more and more noise accumulates, which seriously distorts the signal quality and affects the accuracy of the final judgment

Embodiment Construction

[0044] The present invention will be further described below in conjunction with embodiment.

[0045] From figure 2 It can be seen from the work flow chart of a single-point single-channel high-density seismic exploration data acquisition method that the digital geophone directly converts the vibration dynamic quantity signal into a digital signal and transmits it; it includes the following steps:

[0046] Step 1, micro-logging data input;

[0047] Step 2, calculate optimal explosive quantity and well depth;

[0048] Step 3. Comparing with the experimental well depth and obtaining the correction coefficient

[0049] Step 4. Calibrate the simulated optimal well depth at the micro-logging place, and input the obtained data into the precise shot point design module;

[0050] Step 5, calculating the optimal well depth of each excitation point;

[0051] Step 6, the explosion of underground explosives produces seismic waves;

[0052] Step 7, using a digital detector to receive...

Abstract

Single track, single digital signal detector is adopted in the method to receive signal. The received analog signal is converted to digital signal directly. The converted digital signal is output to signal acquisition station. Arranging and storing the transferred digital signal, the signal acquisition station processes, analyzes and forms geological data. One digital detector is placed at each track, and distance between tracks is 5-10 meter. The invention solves issue that transferring signal through cable, the cascaded type analog signal detector causes signal disturb and signal distortion, and further influencing accuracy of final judgment. The method can carry out transferring signal for long distance in high fidelity. The method raises 20%-50% bandwidth of detection frequency of vibrative dynamic signal for target stratum of coalfield, and 20%-50% bandwidth for target stratum of oil field exploration.

Description

technical field [0001] The present invention relates to an exploration data acquisition method, in particular to a single-point single-channel high-density seismic exploration data acquisition method which utilizes a single-channel, single digital signal detector to receive signals and adopts networked signal transmission. Background technique [0002] The geophysical exploration method is based on the principles of geology and physics, using geophysical prospecting instruments to receive reflection waves from various underground formations on the ground, and obtaining underground geological imaging after computer processing, so as to infer and understand the characteristics of underground geological structures, and to find the required Various mineral deposits provide important reference materials. Among the many geophysical prospecting methods, the most effective and most widely used is the seismic prospecting. [0003] Seismic exploration refers to the process of putting...
