Abstract

Jet injector dosing (mix gas or annotate ash) device mixes a kind of device of different material when being a kind of petroleum drilling and mining refining.

In this device, utilize Jet injector as the mixer that mixes different material (liquid and liquid, liquid and solid, liquid and gas), can simplify the working procedure of preparing a job such as mud, well-killing liquid, injuction increasing liquid in the present job site, reduce utensil, construction site required in the job site, alleviate working strength of workers, improve the mixing quality of mixture.

Description

Jet injector dosing (mix gas or annotate ash) device

The invention belongs to the refining of oil drilling, oil well operation or crude oil and a kind of device that mixes different material such as put.When the operation field of oil drilling, crude oil extraction or refining crude oil, there are many situations several different liquid need be mixed, perhaps liquid is mixed with gas, perhaps liquid is mixed with solid, need prepare mud as drilling well, workover eration need be prepared well-killing liquid, need prepare the low-gravity tubing flow displacement liquid that is mixed with gas during formation testing, need prepare injuction increasing liquid or the like during water filling.This preparation work often needs a large amount of liquid is mixed, at least tens sides, hundreds of side at most.Just need several big jars, pump, mixer, stirrer, mud pit, slurry pump or the like for this reason at the construction field (site), be mixed several liquid or liquid and solid even with the method for circulation spurt.This method is exactly at first with pump several liquid that need to mix to be squeezed in one jar, and then will be extracted into (or returning former jar) in another jar through the preliminary liquid that mixes in this jar, so repeatedly several times after, just can reach the purpose that mixes.

In petroleum drilling engineering, need a large amount of mud.Preparing these mud often all is to need to prepare with Special Equipment in mud plant earlier, comprise pressure fan, solid material jar, pump, mixer, mud pit and have the equipment such as slurry tank that motor drives stirrer, mud will be prepared the back to be drawn toward the job site with special-purpose vehicle, often add various additives again at the scene, could use for wellbore construction after stirring with stirrer according to different requirements.In drilling process, all adopt such process for many years, need large number quipments, manpower, electric power etc.

When oil well carries out well cementing operation, need a large amount of cement slurrys.The job site is with a cover system device at present, after comprising big jar, cementing truck, adding grey device etc. and connect, squeeze into the water of a cementing truck in will big jar and to add grey device, with inflow cement stock tank after the cement mixing with pipeline, squeeze in the well with another cementing truck again, cement the well.

When preparing such as above-mentioned these mixing materials or fluid, devices needed is many, and the site operation handling workload is big, takies very big place, and often all needs the formality of several roads.

Purpose of the present invention is exactly in order to simplify the program of these work, to reduce needed utensil in the oil field operation site operation, reducing the workload of job execution and alleviate working strength of workers design.

Technological scheme of the present invention is: a kind of dosing of oil drilling, oil recovery, crude refining, mixed gas or notes apparatus for ash of being used for, be made up of big jar, pump, mixer, loading hopper, exhaust port etc., its special way is that mixer is by comprising that the Jet injector that shell 2, nozzle 3, trunnion 6, diffusing tube 7, feed cavity 5, power fluid inlet 1, material inlet 4, exhaust port 8 are formed constitutes.The power inlet opening of Jet injector is connected with kinetic pump, and material or additive add from the material feeding mouth of Jet injector, and power fluid is discharged from exhaust port with after material or additive mix in Jet injector.In Jet injector, cooperatively interacting of the nozzle by different-diameter, trunnion, length of throat realizes the mixing of various cooperation ratio.

Figure 2 shows that the basic procedure of this device.By the power fluid of kinetic pump 14 supply jet pumps 15, by loading hopper 12 material is added in the Jet injector 15, after mixing during by trunnion in the Jet injector and diffusing tube, be discharged in the big jar or in the oil well by jet delivery side of pump 16.

Figure 3 shows that mixer is made of two Jet injectors 18,23.Their power fluid inlet is by pipeline 20 parallel connections, and kinetic pump 17 is supplied with their power fluids, and the exhaust port 22 of Jet injector 23 is connected with the material inlet 21 of another Jet injector 18.It is less to be suitable for compound concentration with this mixing arrangement, requires the higher mixed solution of outlet pressure.

Figure 4 shows that mixer is made of three Jet injectors 24,27,31.Their power fluid inlet opening is supplied with power fluid by pipeline 32 parallel connections by kinetic pump 33, and wherein the exhaust port of two Jet injectors 24,31 is connected with the material inlet of another Jet injector 28 by

pipeline

26,29, and mixed liquid is discharged by exhaust port 28.It is less that this mixing arrangement is fit to compound concentration, and add two kinds of different materials, large numbers of mixing material.

Utilize this covering device to prepare mixed solution or various fluid, device therefor is few, and occupied ground is few, can significantly reduce working procedure and working strength of workers, and the liquid or the fluid of preparation are very even, can satisfy the requirement of production scene.Prepare mud with it, can be now with the current at the scene, save the vehicle of special mud plant and roping mud.Annotate grey cement slurry with this device preparation, can injection allocation annotate, use cementing truck less in conjunction with the limit cobordant.During with this covering device preparation fluid injection, can once prepare success, not need to carry out tank switching work repeatedly.

Embodiment: as shown in Figure 5, by clear water jar 35, gate valve 36, connecting line 37, kinetic pump 38, intake pipeline 39, loading hopper 40, Jet injector 41, discharge pipe 42, swirl jet device 43, slurry tank 44, pipeline 45, the mud mixing arrangement that valve 46 grades are formed, it is 10～25mm that nozzle in the Jet injector can adopt diameter, it is 15～40mm that trunnion adopts diameter, length of throat adopts 20～300mm, the mud batching is added by loading hopper 40, clear water is squeezed into Jet injector 41 by kinetic pump 38 by intake pipeline 39, nozzle place in Jet injector produces jet, form low pressure area, the mud batching is sucked, after in trunnion, mixing, squeeze in the slurry tank 44 by Jet injector outlet line 42.In order to make mud mix more evenly, a swirl jet device can be installed in outlet line 42 terminations.The swirl jet device is one and has some cutting sth. askew to the pipe end liquid port in hole, garden in the end.Can prepare qualified mud easily at the scene by such covering device.

When cementing the well, the Jet injector discharge pipe 42 among Fig. 5 directly can be connected on the well head, the cement slurry of preparation is directly squeezed in the well and got final product.

When carrying out workover eration and need prepare tubing flow displacement liquid, Jet injector discharge tube 42 among Fig. 5 directly is connected on the well head, the place adds gas by loading hopper, and it is mixed with fluid in Jet injector, forms low-gravity liquid that contains gas, injects into well.
