Problems solved by technology
This method requires 20-30 square meters of water, which is a large amount of water. After heating the water and injecting it into the oil well, it will not only pollute the oil layer, but also cause well killing, that is, it will take several days to discharge them when the oil well is in production. , affecting output and causing waste
The fuel of this heating furnace is diesel, and the consumption is relatively large.
In addition, when the oil well output fluid is used to reinject the ring sleeve, when the oil well intermittently produces oil, the heating furnace is easy to burn the coil in the heating furnace and cause an explosion, so there is also a large safety hazard

The invention discloses a wellhead oil and gas storage metering device. A heating furnace is connected with an oil-gas separator; a crude oil meter is mounted in the separator and connected with a memory card and a printer; and the oil-gas separator is connected with a gas storage tank. A temperature control instrument and an electromagnetic valve are connected; a spark plug is connected with fuelgas through an electromagnetic valve; a water container and a plunger pump are connected to a heater inlet pipeline; and an air blower is mounted in a furnace mouth of the heating furnace. The wellhead oil and gas storage metering device has the beneficial effects that the oil production rate can be more accurately metered, the gas can be stored to be used as fuel of the heating furnace, so thatthe fuel is saved, self-produced fluid of an oil well can be heated to remove paraffin of the oil well without polluting formation and diminishing production, and the operation of the process is safe.
Description
technical field [0001] The invention relates to an oil well operation device, in particular to a metering device for oil storage and gas storage at the well head. Background technique [0002] The oil well produced fluid contains a large amount of natural gas, and the method of measuring oil with the map has a large error, especially in winter when the fluid temperature is low and the fluidity is poor, so it cannot be measured in real time at the wellhead. In daily production, the crude oil is transported to the metering station through the pipeline, and the meter is used for metering. This method also measures oil and gas at the same time, and the measured figures include the output of oil and gas. In order to know the specific oil production of the oil well, it is necessary to drive the oil tank truck to the oil well, connect the oil outlet pipe of the oil well to the inlet of the oil tank truck, and separately measure the crude oil produced by the well within a certain p...
