Description

Detector for seismic exploration and detector string embedding quality detection device and method Technical Field The application relates to the technical field of detector embedding, in particular to a geophone and a detector string embedding quality detection device and method. Background In seismic exploration, a geophone is used for receiving seismic waves and transmitting acquired seismic signals to a seismic exploration instrument, and the working state of the geophone directly influences the effectiveness and fidelity of seismic exploration data collection. The abnormal results of the technical index test items such as direct current resistance, impedance, sensitivity, damping and distortion of the detector can influence the receiving quality of the seismic signals, and in addition, the receiving quality factors such as embedding angle, pattern placement quality and the like are included. The technical index test items can be tested by periodically using a detector tester to conduct round inspection, and the detectors or detector strings with unqualified test results are replaced to ensure the data quality. But the aspects of embedding quality factors, including embedding angle and pattern placement quality, have not been able to achieve effective supervision. In terms of embedding angle, most of the current wired instruments adopt inclination tests of the system, namely by sending pulse signals, signals fed back by each detector string are compared with an established detector standard model, and a test report is output in a percentage form to generate corresponding data files. For the node instrument, most of the consideration of power consumption and cost of the node unit is that the node instrument does not have an inclination test function or is imperfect in test function, the embedding angle condition of a detector or a detector string cannot be monitored, a detector with an abnormal embedding angle in the acquisition process cannot be timely found and corrected, in addition, when data are processed, seismic channel data with an abnormal embedding angle test result cannot be marked, and reference is made for later data processing. In the aspect of the placement of the detector string graph, the current correct processing mode in construction is to hang the detector on a placement frame by arranging workers or directly measure the distance between groups by a flexible rule, some international projects even adopt flexible ropes which are used for binding the distance between the arranging workers, the placement quality of the detector string graph is improved by the constraint of the flexible ropes, but in actual operation, the placement is limited by the proficiency of operators, responsibility centers, ground surface topography, tolerance of measuring tools and other reasons, no matter a wired instrument or a node instrument can be objectively evaluated, and the quality problem of the detector graph always influences the construction efficiency and the construction quality of seismic exploration.
