The detection device for the detonating signal of the perforating magnetoelectric detonator provided by the invention has the advantages of simple structure, reasonable design, low cost and strong popularization and application value.

Description

Technical field [0001] The invention belongs to the technical field of magnetron detonation signal detection, and in particular relates to a device for detecting the detonation signal of a magnetron detonator for perforation. Background technique [0002] In the petroleum industry, it is basically necessary to use perforating operations on specific well sections, that is, to install perforating bullets in the perforating gun and connect with the magnetic positioning. After the magnetic positioner completes the depth calibration in the well, the detonator on the surface generates the detonation signal. , Through the cable and magnetic locator to reach the detonator in the perforating gun and explode the detonating index to detonate the perforating bullet, so that the metal jet contained in the perforating bullet penetrates the casing and penetrates part of the formation so that the oil and gas can flow into the well. The process of later mining. After the depth calibration of the...

Problems solved by technology

The oscilloscope can be used to observe the waveform curves of various signal amplitudes changing with time, and it can also be used to test various electric quantities, such as voltage, current, frequency, phase difference, amplitude modulation, etc., which has the following disadvantages: high cost; Unintuitive, the oscilloscope has no intuitive frequency, only images can be obtained, and manual calculation is required, which is not conducive to on-site operation; the operation is difficult, because the two test leads need to be connected to the magnetic positioning interface, and both hands are required to operate at the same time, and the oscilloscope can no longer be used at this time To operate; the technical difficulty is relatively high. Since the detonation signal is a signal with a duration of only a few milliseconds, it is time-consuming and laborious to use an oscilloscope to capture the detonation signal. Unskilled operation may also lead to no effective signal. Ordinary ground workers generally cannot complete it. It needs to be operated by engineers with certain technical strength
