The utility model discloses the technical scheme who adopts does:

an oil pipe transportation single well measurement system based on pipe pressure balancer operation, be provided with the metering tank in the system, its characterized in that:

the system also comprises a single pipe, a delivery pipe, a metering pipe and a pipe pressure balancer which are connected from the single well;

the single pipe of each single well is divided into two paths, one path is converged into the conveying pipe, the other path is converged into the metering pipe, the conveying pipe and the metering pipe are simultaneously connected into the pipe pressure balancer, and the pipe pressure balancer is connected into the metering tank through a pipeline.

The pipe pressure balancer comprises a pipe barrel, one end of the pipe barrel is an input port, the other end of the pipe barrel is a piston port, one end of the side face, close to the input port, is an output port, and a piston is arranged in the pipe barrel.

The piston has an outer diameter equal to the inner diameter of the barrel, filling the entire cross-section of the barrel.

The metering pipe is connected with the pipe pressure balancer from the input port, the conveying pipe is connected with the pipe pressure balancer through the piston port, and the output port is connected with the metering tank through the pipeline.

And a valve is arranged on the branch node of the single tube.

The crude oil of the metering pipe enters the pipe pressure balancer from the input port, the piston is pushed to move towards the piston port when the pressure overcomes the pressure outside the piston port, the output port is exposed, and the crude oil is output from the output port and enters the metering pipe through the pipeline.

The crude oil of the metering pipe enters the pipe pressure balancer from the input port, and when the pressure is smaller than the pressure outside the piston port, the piston moves towards the input port to block the output port.

The utility model has the advantages of it is following:

the utility model discloses set up the pipe pressure equalizer on measurement system's website, opened the single pipeline back of single-well, only overcome house steward's pressure when single-well pressure and push away the piston after, single-well crude oil can get into the metering equipment, and the flow that has effectively guaranteed that the single-well gets into the metering equipment is the flow that gets into the house steward. The pipe pressure balancer has reasonable and compact structure, is easy to manufacture and produce, can effectively achieve the aim of balancing, can effectively realize single-well production measurement on the premise of not changing the structure of the original metering system and the arrangement of related pipelines, and ensures the accuracy of production measurement.

Detailed Description

The present invention will be described in detail with reference to the following embodiments.

The utility model relates to an oil pipe conveying single well metering system based on pipe pressure balancer operation, the system is provided with a metering tank 7, adopts the existing tank structure at present, and further comprises a single pipe 1, a conveying pipe, a metering pipe 4 and a pipe pressure balancer 6 which are connected from a single well; the single pipe 1 of each single well is divided into two paths, one path is converged into the conveying pipe 3, the other path is converged into the metering pipe 4, the conveying pipe 3 and the metering pipe 4 are simultaneously connected into the pipe pressure balancer 6, and the pipe pressure balancer 6 is connected into the metering tank 7 through a pipeline. And a valve is arranged on a branch node of the single pipe 1.

The tube pressure balancer 6 comprises a tube 61, one end of the tube 61 is an input port 62, the other end of the tube is a piston port 63, the side surface of the tube is close to the input port 62, one end of the tube is an output port 64, and a piston 65 is arranged in the tube 61. The piston 65 has the same outer diameter as the inner diameter of the barrel 61 and fills the entire cross-section of the barrel 61. The metering pipe 4 is connected to the pipe pressure balancer 6 from the input port 62, the conveying pipe 3 is connected to the pipe pressure balancer 6 through the piston port 63, and the output port 64 is connected to the metering tank 7 through a pipeline.

When crude oil in the metering tube 4 enters the tube pressure balancer 6 from the input port 62, the pressure overcomes the pressure outside the piston port 63 and pushes the piston 65 to move towards the piston port 63, exposing the output port 64, and crude oil is output from the output port 64 through the pipeline and enters the metering tube 4.
