Abstract

The utility model discloses a smart lockable oil well pressure measuring and sampling device, which comprises a main body and a sampler, the main body is a cylindraceous structure, the inner cavity is provided with a valve, the lower part of the valve is connected with a sampling pipe leading to the outside of the main body and a matching sampler, the outer wall of the main body is provided with a mechanical switch lock connected with the valve, the outside of the lock is provided with a protection assembly locked by passwords and the upper and lower end is provided with oil outlet connectors. This utility model adopts a structure that a duplex lock and the main body is separated with the sampler, has a plurality of functions, such as heat preservation, pressure measurement and sampling and theft protection, etc., as well as widely applied to the wellhead facilities for oil exploitation.

Description

Intelligence locking formula oil well pressure measurement sampler

One, technical field

The utility model relates to the oil well sampler, particularly a kind of intelligent locking formula oil well pressure measurement sampler.

Two, background technology

Oil well pressure measurement sampling work is to obtain the important step that number is produced in oil well production operation, and the prior art of finishing this link is to utilize the valve member of exposed flowline to control to finish.But this sampler exists anyone and can open valve and drain the oil, and this provides convenience just for lawless person's stolen, and it is stolen that crude oil often takes place, and valve damages, and causes environment pollution, shortcoming or deficiencies such as economic loss.

Three, summary of the invention

The purpose of this utility model provides a kind of improved intelligent locking formula oil well pressure measurement sampler, shortcoming or deficiency that it can overcome effectively or avoid existing in the above-mentioned prior art prevent lawless person's stolen or destruction, the pollution of environment and the loss of economy effectively.

Intelligent locking formula oil well pressure measurement sampler described in the utility model; comprise main body and sampler; described main body is a cylinder-like structure; inner chamber is equipped with valve; the sampler that this valve bottom is connected with the probe tube outside main body and matches and use; be installed on the mechanical switch lock that is connected with described valve on the main body outer wall, the outer password locking protection assembly that is equipped with of this lock, upper and lower side is equipped with fuel-displaced connector.

Wherein, described sampler comprises the pressure meter of sample cock and top installation thereof and the connector that install at the middle part.

The utility model has following advantage compared with prior art:

1, owing to the double locking structure that has adopted coded lock and the special-purpose phase-locked combination of machinery, so theftproof performance is good.

2, because gas stream is full of the main body inner chamber, sampling process is to the no shear action of liquid stream, so institute's sample thief is accurate, and is representative.

3, because the utility model is the part of oil well flowline, be full of the oil gas aqueous mixtures that comes out in the well in the main body, therefore have insulation effect, avoid frozen winter, have the characteristics of all weather operations.

4, anti-damage performance is strong, and lockhole is not subjected to the restriction of installation direction, therefore installs with easy to operate.

Four, description of drawings

Fig. 1 is the utility model agent structure schematic diagram,

Fig. 2 is the utility model sampler structure schematic diagram.

Five, the specific embodiment

Consult Fig. 1-Fig. 2; a kind of intelligent locking formula oil well pressure measurement sampler; comprise main body and sampler; main body 1 is a cylinder-like structure; inner chamber is equipped with valve 3, and the sampler 7 that this valve bottom is connected with the probe tube 6 outside main body and matches and use is installed on the mechanical switch lock 5 that is connected with described valve on main body 1 outer wall; the outer password locking protection assembly 4 that is equipped with of this lock, upper and lower side is equipped with fuel-displaced connector 2.

Sampler 7 comprises the pressure meter 73 of sample cock 71 and top installation thereof and the connector 72 that install at the middle part.

Claims
