The invention discloses irrigation equipment capable of preventing injected water from backflow for petroleum drilling. The irrigation equipment comprises a water distribution pipe, a water injectionmeter, a pump pressure meter, an impeller, magnetic steel, a down-flow valve, a water pump, a main valve and a separator, the right end of the water distribution pipe is provided with the water injection meter, the left side of the water injection meter is provided with the pump pressure meter, the interior of the water injection meter is rotationally connected with the impeller, the magnetic steel is installed on the lower side of the impeller, a pointer is installed at the upper end of the impeller, a connecting frame is welded to the lower side of a fixing rod, and an inner connecting wheelis integrally arranged on the inner side of the connecting frame. According to the irrigation equipment capable of preventing injected water from backflow for petroleum drilling, the backflow phenomenon caused by pressure difference in the water injection stopping or water injection process can be avoided, ordered water injection is guaranteed, the water pipe can be prevented from being frozen when the temperature is too low by circulating a certain amount of water in the water pipe, the trend of water flow in the water pipe can be rapidly adjusted, fixing is convenient, structure is stable,and operation is easy and convenient.
Description
technical field [0001] The invention relates to the technical field of petroleum drilling, in particular to a water irrigation device for petroleum drilling which can prevent water injection backflow. Background technique [0002] With the development of economy and technology and the advancement of science, oil has become a strategic resource. Oil extraction is of great significance in various countries. Oil extraction requires drilling in the formation. In order to maintain the pressure of the oil layer, it is necessary to inject qualified water into the oil layer. , to replenish energy for the formation and avoid subsidence. There are various irrigation equipment for oil drilling on the market, but there are still some shortcomings; [0003] For example, the current water irrigation equipment for oil drilling is prone to backflow caused by pressure difference when the water injection is stopped or during the water injection process, which easily affects the orderly water ...
