Abstract

The utility model discloses a kind of new polymers samplers, state of the fluid in manifold can more really and accurately be shown, including sampler tank body, weaken fluid shearing degree and weakens the big orifice union elbow of fluid viscosity loss, one end of the union elbow is connected to by anchor tip on fluid line, the other end is connected with sampler tank body, and there are two switches for setting on the sampler tank body, and the switch control sample rate of release far from union elbow is simultaneously connected with sample bottle is contained.The utility model is by the basis of original polymer sampler, the larger union elbow of latus rectum being installed at anchor tip to realize.Union elbow has the latus rectum of bigger and certain camber, on the one hand can slow down fluid admission velocity, weakens shear rate, is on the other hand flowed to by changing, and eliminates turbulent flow, weakens fluid viscosity loss.Such sampling result more can really reflect the viscosity situation of fluid in the duct, avoid secondary shearing caused by sampler.

Description

A kind of new polymers sampler

Technical field

The utility model is related to the sampling process of oilfield injection process, more particularly to a kind of new polymers sampler.

Background technology

The quality of polymer viscosity and gelling strength directly affects the effect of construction, is important during field operation Evaluation index.Under normal conditions, scene can use polymer sampler, the spot sampling in construction process to pass through test specimens Product viscosity observes medicament plastic situation and viscosity loss situation at any time.But time-consuming (takes for sampler sampling at this stage 200mL samples need half an hour), and shear polymer solution phenomenon is obvious.Shear action can cause polymer viscosity to lose, and do Final experimental result is disturbed, usual Field Force, which takes, reduces the method for sample rate to reduce slitter loss.This method consumption When effort, it is inefficient.Problem is that sampler is perpendicular to fluid flow direction, and sampler latus rectum is smaller, manifold at all In have very high pressure (several MPa), this is squeezed during resulting in fluid to enter sampler by very strong stress and viscous Degree loss.

Since time-consuming and viscosity loss is larger for the sampling of existing sampler, the injection feelings of live medicament can not be accurately reflected Condition, in addition can misleading techniques personnel, influence construction effect, therefore, it is necessary to design it is a can solve the above problems novel take Sample device.

Utility model content

The purpose of the utility model is to overcome deficiencies in the prior art, provide a kind of new polymers sampler, this takes Sample device at anchor tip by the basis of original polymer sampler, installing the larger union elbow of latus rectum, can subtract Slow down the fluid flowing gradient while slug flow body admission velocity, can greatly weaken the degree that fluid is sheared in this way.So as to Really and accurately to show state of the fluid in manifold.

Technical solution used by the utility model is：A kind of new polymers sampler, including sampler tank body, and Weaken fluid shearing degree and weaken the big orifice union elbow of fluid viscosity loss, one end of the union elbow passes through fixation Connector is connected on fluid line, and the other end is connected with the sampler tank body, on the sampler tank body there are two settings Switch, the switch control sample rate of release far from the union elbow are simultaneously connected with sample bottle is contained.

Further, the latus rectum of the union elbow is 8-12cm.

The utility model has the beneficial effects that：

The utility model is installed the larger bend pipe of latus rectum at anchor tip and is connect on the basis of original polymer sampler Head slows down the method that fluid admission velocity and change fluid flow direction eliminate turbulent flow, integrally to weaken by increasing pipeline drift diameter Influence caused by shear rate fluid viscosity so that the test result of sampling can really reflect the viscosity feelings of fluid in the duct Condition avoids secondary shearing caused by sampler, closer to the note collecting process of Oil Field.

Viscosity loss caused by the utility model weakens shearing and turbulent flow by adding union elbow, to more accurate The viscosity change situation and plastic situation for symbolizing live medicament are eliminated since viscosity loss caused by sampler itself is to skill The misleading of art personnel.

Attached drawing marks：1- fluid lines, 2- anchor tips, 3- union elbows, 4- switches, 5- sampler tank bodies, 6- switches, 7- contains sample bottle.

Specific implementation mode

For that can further appreciate that the invention, features and effects of the utility model, the following examples are hereby given, and coordinates Detailed description are as follows for attached drawing：

As shown in Fig. 1, a kind of new polymers sampler, including anchor tip 2, sampler tank body 5 are contained sample bottle 7, are opened Close 4/6 and big orifice union elbow 3.

One end of the union elbow 3 is connected to by anchor tip 2 on fluid line 1, the other end and the sampler Tank body 5 is connected.The union elbow 3 has the latus rectum of bigger and certain camber, on the one hand can slow down fluid entrance Speed weakens shear rate, is on the other hand flowed to by changing, and eliminates turbulent flow, weakens fluid viscosity loss.In the present embodiment, The latus rectum of the union elbow 3 is 8-12cm.

There are two switches for setting on the sampler tank body 5, respectively close to the switch 4 of the union elbow 3 and separate The switch 6 of the union elbow 3, the switch 6 control sample rate of release and are connected with the Sheng sample bottle 7.

The sampling process of the utility model sampler is as follows：

The first step：6 are turned off the switch, turns on the switch 4.

Second step：4 are slowly turned on the switch, air in sampler tank body 5 is discharged, is turned off the switch when beginning with liquid outflow 4 and switch 6.

Third walks：6 are turned on the switch, realizes that sample pours by gravity and contains in sample bottle 7.

Although the preferred embodiment of the utility model is described above in conjunction with attached drawing, the utility model is not It is confined to above-mentioned specific implementation mode, the above mentioned embodiment is only schematical, is not restrictive, ability The those of ordinary skill in domain is not departing from the utility model aims and claimed under the enlightenment of the utility model Under ambit, many forms can also be made, these are belonged within the scope of protection of the utility model.
