Description

technical field

[0001] The invention relates to an oil field equipment, in particular to a special underground cable environment detector for an oil field well site. Background technique

[0002] Most oil field well sites are located in the wilderness, and are mainly composed of pumping units, transformers, distribution boxes, underground cables and underground pipelines. According to the production situation, construction operations such as drilling ground anchors and smashing light poles are often required without power failure. Due to the large number of well sites and the complex underground environment, cables or pipelines are often drilled due to construction operations, and the light ones cause equipment losses. Serious ones cause personal injury and death accidents, which have seriously affected the safe operation of production.

[0003] The detection method of the existing underground cable path instrument at present: the transmitter and the receiver are mainly mat...

Embodiment Construction

[0015] Such as figure 1 As shown, the oil field well site includes a pumping unit 1, a transformer 2, a distribution box 3, and an underground cable 4. The transmitter 5 of the underground cable detector is placed on the top of the distribution box 3, and the transmitter 5 is connected to the ground wire 6.

[0016] Such as figure 2 As shown, the signal 7 output by the transmitter 5 is transmitted in the electrical loop formed between the transmitter 5, the distribution box 3, the underground cable 4 and the earth, and the operator can use the receiver to pick up the propagation of the signal 7 on the nearby ground path. Due to the high resistance of the soil, the signal 7 propagating current in the earth is scattered, and once it encounters a cable or metal pipeline during transmission, a concentrated current will be formed in it. Therefore, the present invention can not only find out the path of connecting cables, but also can find out other underground cables and metal p...
