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 proposes an apparatus for acquiring and analyzing well site noise, and belongs to the field of oil drilling. The apparatus comprises: a coupler for coupling well site noise between an oil derrick and a ground electrode; a preamplifier for receiving the noise from the coupler and pre-processing the noise from the coupler; a band-pass filter for performing filtering processing on a noise signal from the preamplifier; a processor which connects and controls the preamplifier and the band-pass filter; and a computer which is connected with the processor. The processor receives noise signals from the preamplifier and the band-pass filter, stores the noise signals and then transmits the noise signals to the computer. The computer analyzes the received noise signals. The invention further proposes a corresponding method for acquiring and analyzing the well site noise. The apparatus and method for acquiring and analyzing the well site noise have high accuracy, is very suitable for analysis of the well site noise, and fill a 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...
