It should be noted that the advantages and the beneficial effects of the utility model are as follows:

1. in view of working efficiency, waiting time in the maintenance process can be reduced, in the traditional maintenance work, operation and maintenance personnel need to restart the integrated load displacement wireless sensor, and the operation and maintenance personnel can restart the integrated load displacement wireless sensor after contacting an oil extractor of an oil extraction factory and waiting for the oil extractor to stop the well before. Illustrating: the working time of operation and maintenance personnel in one day is 10 hours, the working time from a unit to an operation area is 2-3 hours, the midday meal is removed for 1 hour, each pumping well is far away due to the topography of the Qinghai oil field, the time for the way is quite long, and the working time in the operation area is about 4 hours. In the only working time, operation and maintenance personnel judge that the failure cause is that the integrated load displacement wireless sensor needs to be restarted in the oil pumping well, and then the time from half an hour to one hour is needed to wait for the oil extraction plant staff to stop the well before the operation, and then the integrated load displacement wireless sensor is restarted for configuration, so that normal use is restored. The designed auxiliary resetting device for the instrument and the meter of the pumping unit well can easily restart the integrated load displacement wireless sensor under the condition of no well stopping, so that the waiting time of operation and maintenance personnel is greatly saved, and the maintenance efficiency is greatly improved from 3 wells operated and maintained every day to 8 wells operated and maintained at most every day.

2. In view of productivity, in the conventional maintenance work, the integrated load displacement wireless sensor must be restarted after the well stopping operation is performed before the oil production worker. The well stopping time generally needs 10-30 minutes, the calculation is carried out according to the 2016-year financial evaluation parameter 3287 yuan/ton of the group company, the well stopping time of one well is 10-30 minutes, and the calculation result of the direct benefit loss is 100-300 yuan. Under the influence of the severe cold environment of Qinghai oilfield, especially in winter, the well stopping time of 10-30 minutes is likely to cause wax or sand blocking of the pumping unit, so that the pumping unit cannot normally operate, hot car washing and pump checking operations are required, major repair operations are required to be carried out seriously, if the major repair operations are carried out, the calculation result of the direct benefit loss of each day is 6000-8500 yuan, and the productivity and benefit of oil extraction plants are directly influenced. The auxiliary reset device of the instrument and the meter of the pumping unit designed by the user can restart the integrated load displacement wireless sensor under the condition of no well stopping, so that the problem of pumping unit failure is fundamentally avoided, and any loss can not be caused to the productivity and the benefit of an oil extraction plant.

3. In view of economic benefit, in the conventional maintenance work, the time required for stopping the well generally needs 10-30 minutes, which is likely to cause wax or sand blocking of the pumping unit, so that the pumping well cannot normally operate, and it is likely that 250 yuan per hour and 5 yuan per kilometer of the vehicle range are required to be subjected to hot car washing, and the following is exemplified: the recovery time to a near oil extraction plant is 100 km, the working time is 4 hours, and the heat washing cost is 1500 yuan. It is possible that a pump inspection operation is required, and the depth of a well is checked, and when the well depth is more than 1500 meters and less than 2000 meters, 83250 yuan is required for the pump inspection operation; when the well depth is more than 2000 m, 97610 yuan is required for pump detection operation. Major repair work is likely to be required, and 66 ten thousand yuan is required when the well depth is smaller than 2750 meters; when the well depth is greater than 2750 meters, the overhaul operation needs 99 ten thousand yuan. In summary, in the conventional maintenance work, the pumping well is likely to fail to operate normally, the generated cost varies from 1500 yuan to 99 ten thousand yuan, and the auxiliary resetting device for the instrument and meter of the pumping well can restart the integrated load displacement wireless sensor under the condition of no well stopping, so that the maintenance cost of the part can be saved, and the effects of reducing the cost and enhancing the efficiency are achieved.

4. In terms of safety, in the conventional maintenance work, an operator needs to stand on the wellhead to restart the operation of the integrated load displacement wireless sensor, and the auxiliary reset device of the instrument and the meter of the rod-pumped well can avoid the following unsafe factors:

1. in the traditional mode, operation and maintenance personnel stand on the wellhead of the pumping unit to restart the operation of the integrated load displacement wireless sensor, the personnel fall down due to the fact that the personnel skid under the foot, the valve is opened and closed around the wellhead, the secondary collision is likely to be caused after the personnel fall down, the auxiliary reset device of the pumping unit instrument can avoid the operation that the personnel stand on the wellhead, only need stand on the flat ground, the telescopic function of the auxiliary reset device of the pumping unit instrument is utilized, the length of the auxiliary reset device of the pumping unit instrument is adjusted at any time according to actual conditions, and the integrated load displacement wireless sensor is restarted.

2. In the traditional mode, operation and maintenance personnel directly operate by hand on the wellhead through the direct connection station, and although well stopping operation is performed, the failure of a braking system cannot be guaranteed, and if the failure occurs, the risk that the hand is extruded occurs. The auxiliary resetting device of the instrument and the meter of the pumping well can avoid the direct contact of hands of operation and maintenance personnel, but stands on the flat ground to restart the integrated load displacement wireless sensor.

3. From the environmental protection perspective, the generation of dangerous chemical wastes can be reduced. In the traditional mode, operation and maintenance personnel are directly connected with a station to restart the integrated load displacement wireless sensor on a wellhead, and the clothes and the carried gloves are stained with chemicals such as crude oil. The auxiliary resetting device for the instrument and the meter of the pumping well can prevent the clothes and the gloves of operation and maintenance personnel from being stained with chemicals such as crude oil, thereby reducing the generation of dangerous chemical wastes.

In summary, the auxiliary resetting device for the instrument and the meter of the oil pumping well designed by the user not only solves the problems of safety, working efficiency and the like in the maintenance of the daily oil pumping well, but also plays a role in productivity and economic benefit, and becomes one of the indispensable tools in the technical field of oil field information automation tools. Through repeated experiments, the conventional maintenance work is remotely automated in an oil well.
