Problems solved by technology
Although this method is simple, it is not unscientific, and it will cause pollution to the environment. It is no longer suitable for the requirements of modern production and environmental protection, and it is not conducive to fine management.
At the same time, it is also easy to cause the occurrence of oil theft incidents.
[0003] At present, there is no associated gas and liquid recovery and reuse technology and application device

Embodiment Construction
[0026] Such as figure 1 , figure 2 As shown, the wellhead valve 1 is connected to the connecting oil 2 through the clamp 59, one end of the filter check valve 5 is connected to the connecting oil 2, and the other end is connected to the gas-liquid separation data collector 10 through the collector inlet pipe 9, The contact end connecting the non-return valve 2 and the filter non-return valve 5 is a spherical body, so that the connection non-resonator 2 can be rotated arbitrarily within the angle range of ±35°, and connected with the non-return valve 5 of the filter through the non-resonance nut 3 Fixed, a sealing ring 4 is placed at the spherical body connecting the oil nonel 2. A filter screen 6 is provided in the filter check valve 5, and the filter screen 6 is used to purify the solid particles and impurities in the liquid, and prevent the impurity particles from entering the pump body and causing damage to the pump body. In order to prevent liquid backflow, a sphere 7 i...

The invention discloses an associated gas and liquid recycling device. The associated gas and liquid recycling device comprises a wellhead valve, a connecting union, a filter one-way valve, a gas-liquid separation data collector, a gas storage tank, a heat exchanger, a heating furnace, a central control cabinet and a computer, and is characterized in that the wellhead valve is connected with the connecting union through a hoop, and one end of the filter one-way valve is connected with the connecting union through a union nut, and the other end of the filter one-way valve is connected with thegas-liquid separation data collector through a collector liquid inlet pipe; the gas-liquid separation data collector is provided with a liquid outlet and a gas outlet, the liquid outlet is divided into two pipelines to be connected with crude oil output pipelines, and the gas outlet is connected with the gas storage tank through pipelines; a gas outlet of the gas storage tank comprises two pipelines, one pipeline is connected with a crude oil output pipeline, the other pipeline is connected with the heating furnace. According to the associated gas and liquid recycling device, a gear pump and anatural gas pump can be automatically started and stopped according to set parameters, automatic recovery and collection of liquid and gas in oil and casing annulus are realized, scientific management is facilitated, and centralized remote control can be achieved.
Description
technical field [0001] The invention relates to the technical field of petroleum and natural gas exploitation, in particular to an automatic device for collecting and reusing oil and waste liquid, and is a novel device for collecting, recovering and reusing associated oil and liquid. Background technique [0002] At present, the oil and liquid in the oil and casing are usually treated by manual regular or irregular inspection of the liquid in the oil and casing, and the recovery of the oil and liquid in the casing is carried out by a recovery tanker. This method usually relies on people to regularly check and manage the recovered liquid, and does not recover according to the pressure or liquid level of the liquid in the well. The following situations often occur: the recovery is late, and the liquid will overflow, causing environmental pollution. If the recovery is too early, the pressure or level of the liquid in the oil and casing is not enough, the recovered liquid is le...
