Abstract
The utility model discloses a high efficient cement slurry mixing device. The high efficient cement slurry mixing device is provided with a slurry mixing tank. The slurry mixing tank is provided with a mixing blade driven by a motor. The upper portion of the slurry mixing tank is communicated with a function mixer. A cement inlet and a water inlet are disposed on the upper portion of the function mixer. The water inlet is communicated with a water supply pipeline which is connected with a high-pressure injection type centrifugal pump, and is provided with a clear water flowmeter and a pressure gauge. A slurry outlet is arranged on the lower portion of the slurry mixing tank, and is communicated with the function mixer via a slurry return pipeline connected with a slurry mixing circulating pump. The slurry return pipeline is provided with a communicated branch pipeline. The head of the branch pipeline is provided with a cement slurry densitometer which is disposed inside the slurry mixing tank. The slurry return pipeline is communicated with the slurry mixing tank via the branch pipeline and the cement slurry densitometer. The high efficient cement slurry mixing device of the utility model is suitable for the production of cement slurry for welling cementing, has an improved structure, and exhibits high efficiency and fine quality.
Description
Technical field
The utility model relates to a kind of cement slurry processing unit (plant) that is used to reinforce oil well, by automatic control and rational structure, can produce high-quality cement slurry high-effectly.
Background technology
The oil well in oil field will use cement slurry in reinforcing, and the mixed tensor of cement paste and hybrid mode are most important to the quality of cement paste, directly affect the quality and the safety of oil well.Because the compressive strength of cementing concrete is relevant with density, hybrid mode will guarantee the uniformity and the continuity of cement slurry density, viscosity.Under the cement paste prescription condition identical with density, the input mixed tensor is high more, and the Free water of cement paste is few more, and the compressive strength of cement is high more.In order to improve the quality of cement paste, need a kind of high energy mixers, in recent years, high energy mixers enjoyed people to pay close attention to.But the structure of the cement paste blender that uses and performance need improve at present.
The utility model content
The purpose of this utility model is in order to solve the problems of the technologies described above, a kind of High energy water mud mixing arrangement is proposed, this mixing arrangement realizes that with the first mixing once more that mixes and repeatedly shear cement paste of cement and water the high energy high density of cement paste is mixed, and has improved the quality of cement paste greatly.
The purpose of this utility model is achieved through the following technical solutions:
High energy water mud mixing arrangement, be provided with mixed stock tank, in this mixed stock tank, be provided with the blade of puddling of motor drive, the upper end of mixing stock tank is communicated with a function blender, the upper end of this function blender is provided with cement inlet and water inlet, this water inlet is connected high-pressure injection formula centrifugal pump with one water supply line is communicated with, and is provided with clear water flow meter and pressure meter in the water inlet; Be provided with a grout outlet in the lower end of described mixed stock tank, this grout outlet connects the overfall pipeline that mixes the slurry circulation pump by one and is communicated with the function blender; Be provided with the branch pipe(tube) of a connection on the overfall pipeline, the termination of this branch pipe(tube) is provided with a cement slurry density meter, and this densometer is arranged on and mixes in the stock tank, and the overfall pipeline is communicated with mixed stock tank by branch pipe(tube) and cement slurry density meter.
The operating principle of High energy water mud mixing arrangement: clear water is by high-pressure injection formula centrifugal pump pressurization, through the clear water flow meter being housed and manometric water inlet enters the function blender; The cement entrance on blender top, by compressed air input dry cement, clear water and dry cement are tentatively mixed in the function blender.Mix the blade of slurry circulation pump spiral case and can shear cement paste once more, cement paste is puddled.Mix the slurry circulation pump and suck cement paste from mixing stock tank, the cement paste main flow enters the function blender, makes cement paste secondary or repeatedly circulation, and a part of cement paste flows into by branch pipe(tube) and cement slurry density meter and mixes stock tank.Mix the blade of puddling that the oil motor drive is arranged in the stock tank, cement paste is mixed once more.This design has improved in the mixed process cement paste greatly with the ability of evenly puddling of dry cement.In addition, cut sth. askew to entering mixed stock tank from the mixed slurry that the function blender is discharged, cement paste penetrates from the tangentially mixed paddle sheet mouth in bottom in rotation.In rotary course, the gas in the cement paste is discharged from the central tube of dispersing.
High energy water mud mixer of the present utility model and other blender relatively, it is big to have a mixed tensor, mixes slurry evenly, air content is little in the cement paste, structure is comparatively perfect, and is easy and simple to handle, effective, the efficient height, and convenient management, reaction speed is fast, plurality of advantages such as precision height.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The profile of the utility model product is not subjected to the restriction of this figure, and only the profile change also belongs to protection domain of the present utility model.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is described further: embodiment: referring to accompanying drawing, High energy water mud mixing arrangement, be provided with and mix stock tank 1, in this mixed stock tank, be provided with the blade of puddling of motor 2 drives, the upper end of mixing stock tank is communicated with a function blender 4, the upper end of this function blender is provided with cement inlet 5 and water inlet, and this water inlet is connected high-pressure injection formula centrifugal pump 61 with one water supply line 6 is communicated with, and is provided with clear water flow meter and pressure meter in the water inlet; Be provided with a grout outlet in the lower end of described mixed stock tank, this grout outlet connects the overfall pipeline 7 that mixes slurry circulation pump 71 by one and is communicated with the function blender; Be provided with the branch pipe(tube) 31 of a connection on the overfall pipeline, the termination of this branch pipe(tube) is provided with a cement slurry density meter 3, and this densometer is arranged on and mixes in the stock tank, and the overfall pipeline is communicated with mixed stock tank by branch pipe(tube) and cement slurry density meter.
Should be pointed out that for those skilled in the art under the prerequisite that does not break away from the utility model principle, can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
