Abstract
The utility model relates to a pipeline polymer sampler, which comprises an exhaust valve, a sampling valve, a ball valve, a cavity body, an inlet end, and outlet end, a sampling pipe and an exhaust pipe, and is characterized in that the inlet end of the cavity body is orderly connected with the sampling valve and the ball valve, the outlet end is connected with the exhaust valve, the other end of the ball valve is connected with a well head pipeline, all parts are in threaded connection, and the threaded connection positions are wrapped with raw materials for sealing; the ball valve, the sampling valve, the inlet end and the outlet end of the cavity body and the exhaust valve are communicated in the cavity body, the sampling valve is connected with the sampling pipe, and the exhaust valve is connected with the exhaust pipe. When in sampling, a connecting port at one end of the ball valve is connected with the well head pipeline, the exhaust valve and the ball valve are closed, the sampling valve is opened, a polymer solution enters the cavity body under the pipeline pressure, and at this time, the exhaust valve is opened to exhaust air and discharge the partial solution; after the discharged solution is stabilized, the exhaust valve and the ball valve are simultaneously closed, the exhaust valve and the sampling valve are opened again, and the acquired solution is discharged through the sampling pipe.
Description
Technical field
The utility model relates to a kind of oil field used sampler in the oil recovery production field, relates in particular to a kind of canal polymerization thing sampler
Background technology
Canal polymerization thing sampler, be widely used in the oil recovery process of oil, in order to improve the recovery ratio of crude oil, need take a sample to polymer solution, the quality of monitoring polymer, obtain accuracy certification of registered capital material, existing canal polymerization thing sampler commonly used, because the defective in the design only by valve control, is extracted well liquid sample from the well head pipeline, but because the sampler of well head polymer, the function that does not have Oil-gas Separation just gets institute's sample thief data and exists unstability, can not prevent solution shear effectively, the viscosity retention ratio of solution can not get guaranteeing, be difficult to get representative well liquid sample, increased difficulty for the sampling work of polymer, influence ordinary production.
Summary of the invention
In order to overcome existing pipeline opening polymer sampler, can not carry out Oil-gas Separation, extraction sample data instability, the not high many shortcomings of solution viscosity retention rate, the utility model provides a kind of can carry out Oil-gas Separation, prevents solution shear, solution viscosity retention rate height, sampling is accurate, canal polymerization thing sampler easy and simple to handle.
A kind of canal polymerization thing of the utility model sampler is achieved through the following technical solutions.
A kind of canal polymerization thing sampler, comprise outlet valve, sample valve, ball valve, cavity, entrance point, the port of export, probe tube, evacuated tube, it is characterized in that: the entrance point of cavity connects sample valve and ball valve successively, the port of export connects outlet valve, the other end of ball valve is connected with the well head pipeline, described connection, be meant all to adopt between each parts and be threaded, described being threaded, be meant at junction parcel raw material band and realize sealing, ball valve, sample valve, the entrance point of cavity and the port of export, outlet valve is by being connected in the cavity, and sample valve links to each other with probe tube, and outlet valve links to each other with evacuated tube.
A kind of canal polymerization thing of the utility model sampler, by its outlet valve, the sampling that polymer is got solution is finished in the keying of sample valve and ball valve, when technological requirement is taken a sample, one end connector of ball valve is linked to each other with the well head pipeline, close outlet valve, ball valve and sample valve are opened, the polymer solution of from the well head pipeline, adopting up, enter cavity by self pressure, at this moment, slowly open outlet valve, the air that makes cavity is by the evacuated tube emptying, and with air discharge section solution, treat that evacuated tube discharges solution-stabilized after, close outlet valve rapidly, and close ball valve simultaneously, open outlet valve and sample valve again, the solution of being got is discharged by probe tube, has promptly finished the sampling of polymer solution.
A kind of canal polymerization thing of the utility model sampler usefulness is: owing to adopted above-mentioned technical scheme, this well head polymer sampler can be accomplished polymer solution and air separation effectively, prevent solution shear, the solution viscosity retention rate reaches 100%, and simple in structure, easy to operate, dependable performance, sampled data is accurate, helps production management greatly.
