Abstract
The utility model belongs to high-temperature samplers for a wellhead of an oil well, in particular to a high-temperature sampler which can prevent oil well liquid from flash vaporization during high-temperature sampling. The high-temperature sampler comprises a rear sealing head, a central tube, an O-ring seal, a piston, retaining screws, a lead screw, a front sealing head, a short circuit, an elbow, a liquid inlet gate, a liquid outlet gate and a handwheel, and is characterized in that the sealing heads are respectively arranged at the rear and the front part of the central tube; the piston is arranged in the central tube and connected with the lead screw; and the liquid inlet gate and the liquid outlet gate are mounted on the front sealing head. When in sampling, the liquid inlet gate is opened, the lead screw is rotated, and the piston is moved backwards; after liquid enters into the central tube, the liquid inlet gate is closed; when the liquid is cooled, the liquid outlet gate can be opened; afterwards, the lead screw is rotated, and the piston is moved forwards, so that qualified sample can be taken out. The utility model has the benefits of simple structure, easy operation, achievement of high-temperature sampling effect, and safety and environmental protection.
Description
Technical field
The utility model belongs to well mouth of oil well high temperature sampler, a kind of high temperature sampler of flash distillation in the time of especially preventing the sampling of well liquid height temperature.
Background technology
At present, what each elephant of China adopted heavy oil wells high temperature sampling is the gate sampling, the take a sample effect of uncontrollable high temperature flash distillation of this gate, and it is inaccurate to take a sample.
Summary of the invention
In order to overcome the problems referred to above, the utility model provides a kind of high temperature sampler, this high temperature sampler has end socket in the front and back of pipe core, and piston is arranged in the pipe core, piston is connected with leading screw, be equipped with feed liquor gate and fluid gate on the front head, move after opening feed liquor gate rotating threaded shaft piston during sampling, liquid enters and closes the feed liquor gate in the pipe core, open the fluid gate after the liquid cooling, the rotating threaded shaft piston taking-up qualified samples that moves ahead.
The technical scheme in the invention for solving the technical problem is: a kind of high temperature sampler is by rear head, pipe core, O-ring seal, piston, fixed screw, leading screw, front head, short circuit, elbow, the feed liquor gate, the fluid gate, handwheel is formed, its special character is: there is end socket the front and back of pipe core, piston is arranged in the pipe core, piston is connected with leading screw, be equipped with feed liquor gate and fluid gate on the front head, move after opening feed liquor gate rotating threaded shaft piston during sampling, liquid enters and closes the feed liquor gate in the pipe core, open the fluid gate after the liquid cooling, the rotating threaded shaft piston taking-up qualified samples that moves ahead.
The beneficial effects of the utility model are: simple in structure, easy to operate, and the effect of the sampling that can reach a high temperature, safety and environmental protection.
