Embodiment Construction

[0029] The present invention will be further described below in conjunction with accompanying drawing.

[0030] figure 1 A natural gas sampler 100 according to the invention is shown. Such as figure 1 As shown, the natural gas sampler 100 includes a container 1, a piston body 2 and a lead-through 3 (which can be determined by image 3 or see in 4). Wherein, the container 1 has an inlet 4 for connecting with the gas source at the wellhead or the gas source in the gas gathering station. And the outlet 5 of the container 1 is used to connect with the sampling bottle. The piston body 2 is arranged in the container 1 and is in sealing contact with the container 1 , dividing the container 1 into a first space 6 and a second space 7 . The piston body 2 can move along the longitudinal direction of the container 1 under the force, so as to change the volume ratio of the first space 6 and the second space 7, so as to pressurize or depressurize the natural gas therein. Such as im...

Abstract

The invention relates to a natural gas sampler, which is characterized in that it comprises a container with an inlet at one end and an outlet at the other end; a piston body arranged in the container and capable of moving axially along the container, the piston body can divide the container into first space and the second space; the conduction piece arranged on the piston body, the conduction piece can move along the piston body under the action of gas pressure to realize the communication and cut-off of the first space and the second space; used to mark the piston body Position ruler. During the use of the natural gas sampler, by adjusting the position of the piston body, the volumes of the first space and the second space can be adjusted to increase or decrease the pressure of the gas therein. Thus, the two-way change of pressure can be realized through the natural gas sampler. In addition, the natural gas sampler has a simple structure and is easy to operate.

Description

technical field [0001] The invention relates to a sampling device, in particular to a natural gas sampler. Background technique [0002] As the share of natural gas in the country's energy consumption continues to increase, the demand for natural gas continues to grow, so finding more natural gas is a major problem facing explorers in the field of oil and gas industrial production. In order to solve this problem, it is necessary to study the origin and accumulation of natural gas. Therefore, it is necessary to sample natural gas to meet the needs of the research. [0003] In the prior art, the sampling of natural gas mainly uses metal or rubber tubes to connect the gas source in the wellhead or gas gathering station with the sampling bottle, and controls the gas flow sampling through the valve. Due to the different pressures at the inlet of the production well of the gas well or after the separator of the gas gathering station, there may be problems when collecting with sam...
