Problems solved by technology

But the problem is that it only uses the power of the pumping unit to perform the exhaust function, and the discharged natural gas is compressed and input into the oil pipeline.
However, the disadvantage of this patent is that it is not suitable for single well operation in the field, because the single well in the field has no gas pipeline installed due to the long distance between the wells, and only by putting the compressed natural gas into the storage tank, Then it will be pulled away by tank truck at regular intervals
But its existing problems are: high energy consumption, multiple booster pumps consume a lot of energy, high cost, and the benefit is not high compared with the value of the collected natural gas

Abstract

The invention relates to a sulfur-removing, pressurizing and storing device for single-well casing gas. According to the technical scheme, the sulfur-removing, pressurizing and storing device comprises an oil-extraction exhausting device, a chemical reaction device, a natural gas drying device, a multistage labor-saving gas compression device and a compressed gas storage tank; the oil-extraction exhausting device is used for delivering casing gas into the chemical reaction device through a gas outlet pipe after casing gas is extracted; an inner cavity of a gas dryer is filled with a drying agent, and the gas dryer is provided with a compression gas inlet pipe, and is communicated with a reaction tank through a gas-collection connecting pipe; dried natural gas is compressed into a compression storage tank through the multistage labor-saving gas compression device. The sulfur-removing, pressurizing and storing device has the advantages that through reciprocating motion of a beam-pumpingunit, natural gas in a casing pipe can be exhausted and processed in time, and is compressed through the multistage labor-saving gas compression device, and the compressed gas is stored in the gas storage tank, and then is transported away timely through a tank truck; the sulfur-removing, pressurizing and storing device is simple and durable in structure, great reduction of energy consumption canbe achieved, and as the device adopts a mechanical structure, the device is more durable.

Description

technical field [0001] The invention relates to an oil field single well production auxiliary device and method, in particular to a single well casing gas desulfurization pressurized storage device. Background technique [0002] In oil extraction, there are many field single wells, and there are also a large number of high permeability wells in these single wells. Due to the large amount of natural gas associated in the formation, it is not enough to form natural gas development wells. In this way, in the process of oil extraction, due to a large number of The existence of gas will cause the gas pressure in the casing of the oil well to rise, and the dynamic liquid level of the oil well will drop due to the rise of gas pressure, which will lead to insufficient liquid supply of the oil well. The gas is released or drawn out for combustion. After the gas is released, the dynamic liquid level of the casing will be raised to the normal height, and then the oil production operati...
