Description

A kind of fracturing fluid positioning and quantitative sampler
Technical field
The utility model is related to a kind of sampler, more particularly to a kind of fracturing fluid positioning and quantitative sampler.
Background technology
Fracturing fluid is the working solution of oil gas field reservoir reconstruction, and type is various, including water-based fracturing liquid system, Oil Base Fracturing Liquid system, alcohol-base fracturing fluid system etc., based on aqueous fracturing fluid, additive includes mainly thickening for mainly application domestic at present Agent, clay stabilizer, fungicide, surfactant, pH adjusting agent etc..
Since fluid volume is huge in reservoir reconstruction work progress, transportation cost is higher in addition, therefore domestic fracturing fluid at present Use mainly use construction site prepare method.Concrete configuration process is:Flow container matches clear water in liquid pump circulating tank for water, It is formed by negative pressure using jet stream, additive is uniformly blended into water, fracturing fluid is completed and prepares.To additive in process for preparation Before addition sequence has strict demand, technical indicator to be not up to, a kind of additive under addition easily causes and fails with liquid, therefore presses The quality-monitoring split in liquid process for preparation is most important, and detection process needs frequently sampling;Simultaneously because surfactant It is added, in fracturing fluid process for preparation, easily generates a large amount of foams and float on liquid surface, thickness is up to 50cm-80cm, seriously Influence the progress of sampling, it is therefore desirable to which a kind of continuous positioning of design, quantitative sampling device take to be pinpointed in frac tank Sample, excludes the influence of foam, and guarantee obtains the authenticity and objectivity of sample.
It is investigated by early period, currently used liquid positioning sampler can make under the inlet of sampler to specified The sample of designated depth, achievees the purpose that sampling in depth extraction storage tank.But currently used liquid positioning sampler exists Obvious shortcoming, first, structure is too simple, and rubber stopper and sampler are split type, plug repeatedly and easily cause poorly sealed, shadow Ring sampling accuracy;Second, sampler can not determine depth selection;Third, sampler can not determine the body of collected sample Product;4th, sampler cleaning inside is more difficult, easily causes continuous sampling pollution.
Invention content
The utility model can not determine depth selection to help to solve existing liquid positioning sampler, can not determine Sample volume plugs and easily causes the problems such as poorly sealed, cleaning is difficult repeatedly, and provides a kind of fracturing fluid positioning and quantitative sampling Device.
The utility model includes sleeve, center-pole, cup lid and sample storage cup, and middle sleeve lower end is connect with cup lid, center-pole Through sleeve and cup lid, lower end is connected with sample storage cup, and cup lid is located at sample storage cup upper end opening.
Sample storage cup lower end is equipped with liquid outlet.
Sleeve upper end is equipped with handle, and center-pole upper end is equipped with handle, and spring is equipped between handle and handle, and spring is set in On center-pole.
Sealing ring is equipped between lower cartridge and center-pole.
Cup lid is equipped with sealing rubber ring with sample storage cup contact position.
Center-pole lower end inside link and sample storage cup by being connected.
Scale is equipped on the outside of sleeve.
The operation principle of the utility model:
The present apparatus under normal conditions, due to the tension force of spring effect between handle and handle, makes the cup lid quilt of sleeve lower end It squeezes, closely covers on sample storage cup.
In sampling process, sampler is inserted vertically into frac tank to be taken, depth selection is read by the scale on the outside of sleeve Take, since sample storage cup upper end opening is everywhere in sealing state, sampler insertion process, due to the effect of pressure, fracturing fluid without Method is flowed into from sample storage bottom of a cup portion fluid hole in sample storage cup, and device to be sampled reaches predetermined depth, and fixed handle firmly pulls up handle Hand, spring are compressed, and sleeve drives cup lid to move upwards, and sample storage cup upper end opening is opened, and fracturing fluid sample is from opening stream Enter in sample storage cup, after a period of time, wait for that sample storage cup is full, unclamp handle, spring is released, under the force of a spring sleeve to Lower promotion cup lid is covered on sample storage cup and is open, and sample storage cup is again at sealing state, due to the effect of pressure, sample storage Fracturing fluid sample can not be flowed out from bottom fluid hole in cup.It extracts sampler out, sample storage bottom of a cup portion fluid hole is directed at sampling container, Pull handle opens cup lid again, and fracturing fluid sample flows into sampling container, completes sampling.
After sampling, sample storage cup need to only be cleared up.Since sample storage cup volume is fixed, take every time The volume of sample is also certain.
The beneficial effects of the utility model:
Sampler structure provided by the utility model is simple, easy to operate, can effectively be controlled by the scale on the outside of sleeve The deep depth of sampler processed, the volume of samples taken is determined by the volume of sample storage cup, is fully achieved fracturing fluid and was prepared Fixed point, quantitative sampling in journey.Greatly ensure that samples taken authenticity and objectivity, at the same the device can also be achieved it is multiple The continuous sampling of flow container, sample rate is fast, and cleaning is easy after sampling.
