Problems solved by technology
[0002] When detecting underground pipelines in oil fields, first set up the transmitter, fix the positive pole of the clamp of the transmitter to the pipeline, and the negative pole of the clamp is grounded through the ground braze, turn on the power of the transmitter, adjust the frequency, receive the signal with the receiver, and judge the direction of the pipeline , this conventional method can detect the pipeline at a distance of about 500 meters at a time. If the distance exceeds a certain distance, the current signal will attenuate, so that the receiver cannot receive the signal, and the transmitter can only be re-set up, which brings great inconvenience to long-distance pipeline detection.

Embodiment Construction
[0016] refer to figure 1 , a device for effectively increasing the detection distance of underground pipelines in oil fields, including a transmitter and a receiver, and also includes a signal generator, the transmitting frequency of the signal generator is the same as that of the transmitter and the receiver, and its output power is 2 times the output power.
[0017] When conducting underground pipeline detection, first set up the transmitter, fix the positive pole of the clamp of the transmitter to the pipeline, the negative pole of the clamp is grounded through the copper-clad steel grounding device, and the grounding point of the transmitter is set at an interval of about 50 meters from the underground pipeline. Power the transmitter, adjust the frequency, turn on the receiver to select the same frequency as the transmitter, use the receiver to receive the signal, and judge the direction of the pipeline. The pipeline can be detected at a distance of 500 meters to 800 meter...

The invention discloses a device for effectively increasing a detection range of an underground pipeline of an oil field. The device comprises a transmitter and a receiver, and further comprises a signal generator, wherein the transmitting frequency of the signal generator is the same as the frequency of the transmitter and the frequency of the receiver, and the output power of the signal generator is double of the output power of the transmitter. A method for effectively increasing the detection range of the underground pipeline of the oil field comprises the following steps of connecting the transmitter; opening the receiver for detecting; connecting the signal generator; continuing detecting. In comparison with the prior art, the device and the method have the following advantages that after the transmitter is erected, one signal generator device is applied to a detected pipeline, so that a transmission range of a current signal on the pipeline is effectively enlarged and the length for pipeline detection is increased; after the method is applied, the detection range can be effectively lengthened by about 1000 meters, the detection range of the pipeline is greatly improved, the frequency for replacing the transmitter is effectively reduced and the detection efficiency is improved.
Description
technical field [0001] The invention relates to the technical field of underground pipeline detection, in particular to a device and method for effectively increasing the detection distance of underground pipelines in oil fields. Background technique [0002] When detecting underground pipelines in oil fields, first set up the transmitter, fix the positive pole of the clamp of the transmitter to the pipeline, and the negative pole of the clamp is grounded through the ground braze, turn on the power of the transmitter, adjust the frequency, receive the signal with the receiver, and judge the direction of the pipeline , This conventional method can detect the pipeline at a distance of about 500 meters at a time. If it exceeds a certain distance, the current signal will attenuate, so that the receiver cannot receive the signal, and the transmitter can only be re-erected, which brings great inconvenience to long-distance pipeline detection.
