Embodiment Construction

[0043] Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

[0044] The invention provides a device for collecting and analyzing well site noise and a related method, which are used for collecting and analyzing statistical characteristics and statistical laws of well site noise.

[0045] figure 1 The device 4 for collecting and analyzing well site noise according to the present invention is schematically shown.

[0046] refer to figure 1 , the device 4 according to the invention comprises an electromagnetic noise coupler 6 . The electromagnetic noise coupler 6 mainly couples the electromagnetic signal of the well site through the ground electrode, mainly the electromagnetic noise between the ground electrode and the derrick, and realizes signal superposition and impedance transformation to effectively collect external electromagnetic signals; at the same time, the grounding resistance can be considered According to the...

Abstract

The invention provides a device for collecting and analyzing well site noise, which belongs to the field of petroleum drilling. The device includes: a coupler, used to couple the well site noise between the derrick and the surface electrode; a preamplifier, used to receive the noise from the coupler and preprocess it; a bandpass filter, used to The noise signal of the pre-amplifier is filtered; the processor is connected to and controls the pre-amplifier and the band-pass filter; the computer connected to the processor, wherein the processor accepts the noise signal from the pre-amplifier and the band-pass filter, After it is stored, it is sent to the computer, and the computer analyzes the received noise signal. The invention also proposes a corresponding method for collecting and analyzing well site noise. The device and method according to the invention have high precision, are very suitable for the analysis of well site noise, and make up for the gap in the prior art.

Description

technical field [0001] The invention relates to a device for collecting and analyzing well site noise, which belongs to the field of petroleum drilling. [0002] The invention also relates to a method for collecting and analyzing well site noise. Background technique [0003] Electromagnetic fields exist in space, the atmosphere, the surface of the earth, and underground. Human life and industrial equipment and instruments are usually in a specific electromagnetic environment. In the process of oil exploration and development, the electromagnetic noise in the well site may cause serious harm to the personal, environment and operation safety. In particular, noise interference will damage the control accuracy and service life of various measuring instruments and equipment, and even affect the quality of drilling engineering. [0004] In the drilling site of oil exploration and development, due to the existence of a large number of power pipe networks, power equipment and ele...
