A cone-shaped body is arranged on the upper portion of the upper conical head, a cylinder is arranged on the lower portion of the upper conical head, a connector with the connection union is arranged on the top of the conical head at the upper end, a regulating valve seat perpendicular to the axis is arranged on the cylinder of the upper conical head, the regulating valve is arranged on the regulating valve seat, and the piston assembly is arranged in the body. The connection union is connected with a liquid inlet pipe at the inlet of a well mouth production block valve through a valve, the liquid inlet valve is connected with a liquid inlet pipe at the inlet of a polymer injection liquid control valve, and an online sampling bypass capable of reflecting actual viscosity of polymer is formed. Authenticity of samples and availability of testing data are guaranteed.
Description
Technical field
The utility model relates to a kind of tertiary oil production in oil field injection-gathering well head on-line sampler, and concrete effect is exactly by the taking-up with pressure of the polymer solution in polymer injection well head flow process, improves to greatest extent the poly-fluid viscosity retention rate of note, improves the validity of sample.
Background technology
Shengli Oil Field, through constantly exploitation, has entered tertiary phase at present, wherein the most generally polymer flooding exploitation.In polymer flooding, the viscosity of polymer is one of key factor determining oil displacement efficiency.In polymer flooding, the detection of solution viscosity is mainly in order to guarantee oil displacement effect of polymer, understands the situations such as surface technology flow process viscosity loss and the poly-equipment service behaviour of note.Our on-the-spot polymer injection well head sampler used is longer sample time at present, solution shear is large, worker's labour intensity is large, be there is to certain inadaptability in the detection of current injection viscosity, testing result is inaccurate, injecting data accurately can not be provided, give sample examination and instruct note consor to produce and bring difficulty, can not meet current production requirement.
Summary of the invention
The purpose of this utility model is to provide a kind of injection-gathering well head on-line sampler, can take the defect that above-mentioned prior art exists.
The technical solution of the utility model is achieved in the following ways:
The utility model comprises: liquid feed valve, sample valve, control valve, body, piston assembly, sealing ring and connection oil ninth of the ten Heavenly Stems, body is made as cylindrical shape, upper and lower two ends are provided with conical head, at the conical head top of lower end, be provided with one with the feed tube of liquid feed valve, all sides are provided with one with the probe tube of sample valve; The top of upper conical end socket is made as bullet, bottom is made as cylinder, at the conical head top of upper end, be provided with the joint that a band connects union, on the cylinder of upper conical end socket, be provided with the regulating valve seat in a vertical axle center, regulating valve seat is provided with a control valve, is provided with a piston and becomes in body; Connect union and be connected with the feed tube of the import department of well head production gate by valve, liquid feed valve gathers to come the feed tube of hydraulic control valve door import department to be connected with note, forms a sampling bypass.
Piston assembly comprises piston, centralizer, connecting bolt and nut, in piston periphery, is provided with seal groove, is provided with sealing ring in groove, and piston and centralizer center are provided with bolt hole, by bolt and nut, piston and nut is linked together.
Control valve is made as three-way adjustable valve, and three through holes are communicated with street corner, chamber body and left conical head with union respectively.
the beneficial effects of the utility model are:
Polymer solution in the time of can taking out at any time normal injection, has avoided being degraded because shearing, and solution viscosity can reduce, and causes the inaccurate drawback of analysis data of solution; Easy and simple to handle, quick.Sampling operation is equal to oil well sampling, and a people can complete, and has avoided potential safety hazard; During sampling, without emptying, can take out the qualified sample liquid in Well head flow path, without environmental nonpollution.Without Insulation, reduced management difficulty winter.

The specific embodiment
Below in conjunction with 1 pair of enforcement of the present utility model of accompanying drawing, be further elaborated:
The utility model comprises: liquid feed valve 1, sample valve 2, control valve 3, body 7, piston assembly 4, sealing ring 5 and be connected oil the ninth of the ten Heavenly Stems 6, body 7 is made as cylindrical shape, upper and lower two ends are provided with conical head, at the conical head top of lower end, be provided with one with the feed tube of liquid feed valve 1, all sides are provided with one with the probe tube of sample valve 2; The top of upper conical end socket is made as bullet, bottom is made as cylinder, at the conical head top of upper end, be provided with the joint that a band connects union 6, on the cylinder of upper conical end socket, be provided with the regulating valve seat in a vertical axle center, regulating valve seat is provided with a control valve 3, and upper conical end socket is threaded with body; In body, be provided with a piston assembly 4; Connect union and be connected with the feed tube of the import department of well head production gate by valve, liquid feed valve gathers to come the feed tube of hydraulic control valve door import department to be connected with note, forms a sampling bypass.
During the normal injection of polymer liquid of injection well, sampling bypass two ends are closed, and open liquid feed valve during sampling, and polymer liquid enters in body, push piston assembly is up to summit, in body, be full of polymer liquid, open sample valve and start sampling, now open valve and the control valve of union side, piston assembly is descending, pushing away polymer liquid and flowing out from sample valve, with the downstream rate of control valve regulating piston assembly, i.e. sample rate.Take and close sample valve after sample and control valve completes sampling work.While sampling, open control valve next time, be communicated with inferior pyramidal end socket, open liquid feed valve, form low-pressure area at inferior pyramidal public attention place, the polymer liquid that control valve is come is carried into entering body, piston assembly is up, and the dead liquid in its top is discharged, and after dead liquid takes, is obtaining sample as official sample.
