Using method of horizontal type oil production and gas exhaust synchronous production device

Abstract

The invention relates to a using method of a horizontal type oil production and gas exhaust synchronous production device. According to the technical scheme, an gas inlet pipe of a wellhead connectingshort section is connected to the horizontal type gas exhaust device, and a suction piston and a return spring are installed in an inner cavity of a horizontal type sealing cylinder liner; the outerend of the suction piston in the horizontal type sealing cylinder liner is connected to a draw cord position finding block by winding a fixed pulley through a draw cord, and the draw cord position finding block is installed at the rear end of a walking beam; the beam walking is driven by an electric motor to swing up and down, and the oil production is realized while gas exhausting. The using method of the horizontal type oil production and gas exhaust synchronous production device has the beneficial effects that the reciprocating motion of a walking beam type pumping unit is utilized to enable the horizontal type gas exhaust device to discharge natural gas in a casing in time, the weight principle of the walking beam type pumping unit and the conversion of potential energy and kinetic energy are utilized to enable a whole pumping system to be more energy-saving, and a horizontal type structure is more safe and reliable; and in addition, the discharge of the natural gas is realized synchronously, and the natural gas is subjected to preliminary removal of hydrogen sulfide to avoid the occurrence of a poisoning safety accident on field staff.

Description

technical field [0001] The invention relates to an oil production casing gas processing device, in particular to a method for using a horizontal oil production exhaust gas synchronous production device. Background technique [0002] In oil extraction, there are a large number of high-permeability wells, because there is a large amount of natural gas associated in the formation, but it is not enough to form a natural gas development well. In this way, in the process of oil extraction, due to the existence of a large amount of gas, the gas pressure in the casing of the oil well will be caused. However, the dynamic liquid level of the oil well will drop due to the increase of gas pressure, which will lead to insufficient liquid supply of the oil well. Therefore, the well must be stopped at this time, and then a large amount of gas in the casing must be released. After the gas is released, the casing will The dynamic fluid level of the pump can be raised to the normal height, an...

Problems solved by technology

But the problem is whether it only has the exhaust function, or it needs to shut down the well

However, the problem that it exists is that it only uses the power of the pumping unit to perform the exhaust function, and it cannot produce oil and exhaust at the same time.

This patent realizes the extraction of gas while producing oil, but its existing problems are: the air pump is installed vertically, which has certain safety hazards. In addition, the power source comes from the pumping unit, but the counterweight principle of the pumping unit is not used. And the fixed pulley principle, its working process consumes electricity, does not save energy, and is not suitable for the existing energy-saving environment, and the natural gas after pumping does not carry out the work of removing hydrogen sulfide, resulting in hydrogen sulfide poisoning, Potential safety hazards such as death
