Background
According to the existing oil field oil well gathering and transporting pipeline, under the conditions of time, road conditions, external coordination and the like, a plurality of pipelines can be crossed and merged for oil transportation. This makes it difficult to determine the specific well group number of the incoming oil at the same location in the event of a line puncture or freeze blockage. Previous methods have been based on experience or suspected wellsite outages, or heated hot-wash suspected pipelines with hot-wash vehicles. The method often has misjudgment to a great extent, causes pollution and production stagnation, and if the method of hot washing the pipeline is adopted, the cost is high, the production interruption time of the oil well is long, and great passivity is brought to the crude oil production. Therefore, a device with strong practicability and convenient operation needs to be invented to quickly discriminate the faulty pipeline.

In order to achieve the purpose, the invention adopts the technical scheme that: the crude oil pipeline discrimination instrument comprises a first transmitting probe arranged at one end of a crude oil pipeline and a first receiving probe arranged at the other end of the crude oil pipeline.
The first transmitting end probe is connected with a 7.4V power supply and is connected in series by adopting two 18650 lithium batteries; the first transmitting end probe adopts an STM32c8t6 singlechip, the first transmitting end probe controls the output of the main control chip by a program, and the amplitude is 12V; the transmitting end probe is connected with the head end of the crude oil pipeline;
the receiving end probe I is connected with a 7.4V power supply and adopts two 18650 lithium batteries which are connected in series; the receiving end probe I adopts an STM32c8t6 singlechip; the first receiving end probe outputs the received voltage square wave signal to an AD detection pin of the single chip microcomputer, the AD value and the frequency are detected, and when the 1KHZ square wave signal is detected, the indicator lamp is turned on; the first receiving end probe is connected with the crude oil pipeline.
The crude oil pipeline discrimination instrument comprises a first transmitting probe and a second transmitting probe, wherein the first transmitting probe and the second transmitting probe are respectively arranged at one end of a crude oil pipeline and one end of a crude oil pipeline; and the receiving end probe I is arranged at the other end of the crude oil pipeline I or the crude oil pipeline II.
The invention has the beneficial effects that:
the safety is ensured because the voltage adopted by the whole instrument is less than the human body safety voltage (36V).
The device mainly comprises a micro-current switcher, an electric signal screener, a current releaser and an electric shock device, and can install the signal screener at the mouths of suspected wells of each well group through electric signals, release current through the electric shock device and react the current on the well group screener of a fault oil pipe. The device can amplify the click effect through the screener, and thoroughly eliminate the influence of the crossed pipelines, which is the pipeline lapping together in common saying by us. The device releases micro-current through the current releaser, and the safe current can not cause accidents. The equipment is simple to operate, high in reliability, easy to operate and suitable for popularization and use in oil fields.
