Problems solved by technology

[0002] At present, there are three methods for collecting gas samples in oil fields, gas cylinder method, sample bag method and drainage method. The main disadvantage of gas cylinder or sample bag method is that air pollution to the collected gas cannot be avoided during the sampling process, and the operator must grasp the Appliances, facing the risk of poisoning and high voltage injury
The disadvantage of conventional drainage method sampling is that the operator must hold the gas cylinder and the air pipe, and directly touch the collected gas and liquid with hands, facing the risk of freezing hands and poisoning, and the amount of gas sample collection cannot be effectively controlled

Embodiment

[0019] one. Multifunctional toxic gas drainage method automatic gas sample collector:

[0020] Between the side walls of the sampling pool 1 of the collector, there is a horizontal sliding rod 2 with a horizontal sliding sleeve 3, and the side of the horizontal sliding rod 2 is connected to the horizontal rotating ring 5 through the connector 4 screws, and the other end of the horizontal rotating ring 5 is welded by stainless steel argon arc. Rotate the middle part of the bracket 6, and the rotating bracket 6 is connected with the longitudinal sliding rod 8 of the longitudinal sliding sleeve 7, and the longitudinal sliding sleeve 7 is connected with the clamp 11 for clamping the collection bottle 9. The gas introduction pipe 12 is arranged under the collecting bottle 9 , and the gas introduction pipe 12 communicates with the gas control valve 14 through the pulse electromagnetic valve 13 arranged outside the sampling pool 1 . The outer wall of the sampling pool 1 is connected...

Abstract

The invention discloses a multifunctional drainage automatic gas sample collector for toxic gas and a gas collecting method, which are designed for realizing gas sample collecting standard operation and improving monitoring technology levels. The automatic gas sample collector mainly comprises a bottle plug rack arranged in a sampling pool, sampling and water injection scales, a transverse slide bushing, a transverse slide rod, a horizontal rotating ring connecting the transverse slide bushing with a rotary rack, a longitudinal slide rod connected with the rotary rack and sheathed with a longitudinal slide bushing, a loop clamping a collecting bottle, a pulse magnetic valve connected with an air inducing pipe, an air control valve, and the like. The automatic gas sample collector is a special device, has standard operation, and can obviously improve the sampling success rate; an operator does not contact water directly, thus avoiding the frozen risk completely; the gas collection amount of the collecting bottle can be controlled through the water injection amount of the sampling pool; the collection operation can be controlled automatically, so that the operator avoids the poisoning risk; the sample is got in clear water of the sampling pool, so that the content of the dissolved oxygen in air can be reduced, and the gas sample is prevented from being contaminated.

Description

technical field [0001] The invention relates to a multifunctional toxic gas drainage method automatic gas sample collector and a gas collection method thereof, belonging to the technical field of gas sample collection for oil field production. Background technique [0002] At present, there are three methods for collecting gas samples in oil fields, gas cylinder method, sample bag method and drainage method. The main disadvantage of gas cylinder or sample bag method is that air pollution to the collected gas cannot be avoided during the sampling process, and the operator must grasp the If you don't hold the appliance, you will face risks such as poisoning and high voltage injury. The disadvantage of conventional drainage method sampling is that the operator must hold the gas cylinder and the air pipe, and directly touch the collected gas and liquid with hands, facing the risk of freezing hands and poisoning, and cannot effectively control the amount of gas sample collected. ...
