Description
Technical field
The utility model belongs to the sampler of oil exploitation oil well sample examination, particularly the overflow-type sampler.
Background technology
Old-fashioned sampler is at oil well production gate output, a sampler is installed, be exposed to well head box outside, not antifreeze, find during sampling that sampler freezes, the oil recovery worker with fire roasting logical after sampling (causing very unsafe factor) again, opening the sluices during sampling enters in the bottle a large amount of natural gas of oil well and effluxes, and liquid falls into bottle, reaches the sampling purpose.On average every mouthful of well about 10 minutes sample times (sampler freezes, and the roasting time of fire is disregarded), every mouthful of well on average effluxes about 3 cubic metres of natural gases to the workman, has both wasted the energy, has increased working strength of workers again.
Summary of the invention
The purpose of this utility model is to provide a kind of overflow-type sampler, and it is rational in infrastructure, and is easy and simple to handle, and sampling is convenient, and is time saving and energy saving, and has avoided natural gas to efflux during sampling, and energy conservation can also be antifreeze, still can normally use in the winter time.
The purpose of this utility model is achieved in that a kind of overflow-type sampler, upper flange and lower flange are being set respectively on the end face of sampler cylindrical shell and the bottom surface, the through hole of symmetry is being set on the barrel of cylindrical shell cross central line, the plunger tube of one end sealing is installed on the through hole of symmetry movingly, wherein the blind end of plunger tube be fixed on the cylindrical shell through hole the sealing base movingly, the openend of plunger tube stretches out the barrel wall through hole, and with sealed support on the through hole movingly, in plunger tube, cooperate the plunger conduit with axially extending bore is installed, the plunger of plunger catheter tail and plunger tube are movingly, the retaining cap through hole that conduit that it is anterior and plunger tube opening part are installed movingly, the catheter proximal end of stretching out plunger tube is being provided with the sampling mouth of 90 ° of bendings downwards, be positioned at affixed uncovered oil-collecting bowl on the plunger tube of cylindrical shell, the through hole of oil-collecting bowl by the bottom is communicated with plunger tube, stretching out affixed handle on the plunger tube of tight socket.
Structure design of the present utility model is fit to be installed in the well head box, and the utility model is installed between oil well production gate and the back pressure gate.Lower flange of the present utility model is connected with the wellhead back pressure gate, and upper flange is connected with the output pipe nipple of oil well production gate.This mounting structure makes the utility model be positioned at the well head box.During the oil well ordinary production, liquids and gases in the oil well are simultaneously by producing gate by in the oil-collecting bowl in the import inflow sampler cylindrical shell of upper flange, and this moment, the oil-collecting bowl bottom was shut by the plunger of return with the through hole on the plunger tube, after liquid in the oil-collecting bowl fills, liquids and gases overflow oil-collecting bowl simultaneously, enter gathering line by the back pressure gate.When needs are taken a sample, open the wicket on the well head box, hold the sampling mouth and be pulled outwardly the plunger conduit, through hole is opened, pressure by oil well enters plunger tube with liquid by through hole, is discharged to through the sampling mouth by the plunger conduit with axially extending bore to connect in the oil bottle, reaches the purpose of sampling, inwardly push away the plunger conduit then and make the plunger return, sampling finishes.After each sampling finishes, hold handle and be rotated down 180 degree, the liquid in the oil-collecting bowl is outwelled, rotate up 180 degree playback again.The wicket of shutting the well head box can reach antifreeze purpose.The utility model is easy to operate, and with arriving with sampling, the process of sampling only needed for 6 seconds, had alleviated working strength of workers, did not have natural gas to discharge in the sampling process, had reached the purpose of energy-saving and emission-reduction.The utility model is rational in infrastructure, and is easy and simple to handle, and sampling is convenient, and is time saving and energy saving, and avoided natural gas to efflux during sampling, and energy conservation can also be antifreeze, still can normally use in the winter time.
