Abstract
The utility model relates to a slurry purifying sand removing device, comprising three filtering devices, primary and secondary filtering devices are formed by two hydrocyclonic sand removing devices in series, and fixed at the upper part of a frame, a third filtering device is a vibrating screen and disposed below the primary and secondary filtering devices and at the lower part of the frame. An overflow pipe of a first-stage hydrocyclonic sand removing device is communicated with a slurry inlet pipe of a second-stage hydrocyclonic sand removing device, and sand discharge openings of the two hydrocyclonic sand removing devices are right opposite to the screen mesh middle part of a vibrating screen. Via the above technical scheme, after the slurry is purified by the slurry purifying sand removing device, the sand content of the slurry is reduced by 70%, excellent performance of the slurry is guaranteed, average driller-month efficiency is improved by 21.3%, drilling efficiency is improved, consumption of vulnerable parts (cylinders, pistons, valve bodies) of a slurry pump is reduced; wearing of a drilling rod and a drilling tool is reduced, consumption of pulping material and pulping water is reduced, slurry cost is reduced by 42.6%, waste slurry discharge capacity is reduced, and environment pollution is reduced.
Description
Technical field
The utility model relates to a kind of mud purification desander.
Background technology
Solid phase in the mud can be divided into two classes by its effect: a class is useful solid phase, such as swell soil, chemical treatments, blanc fixe etc.; Another kind of is useless solid phase, such as drilling cuttings, swell soil inferior, sand grains etc.So-called drilling fluid solid control will be eliminated harmful solid phase exactly, preserves and uses solid phase, to satisfy drilling technology to the requirement of property of drilling fluid.At present, the method for solid concentration in four kinds of reduction mud commonly used is arranged: the first is to dilute drilling fluid with clear water, and the method has just unilaterally reduced the solid concentration in the mud, and useless useless solid phase in the mud is got rid of mud system fully; The second is to come mud in the replacement well with clear water and the qualified new mud of performance, and the method had both increased useless slurry discharge value, had increased the weight of environment pollution, had wasted again mud materials, had increased the mud cost; The third is the gravity that utilizes solid, allows the solid separation that oneself sinks in grit chamber, and the method can be destroyed mud property; The 4th kind is to use the mechanical cleaning method, and the above three kinds of method desanding effects of the method are obvious, but because the difference of drilling technology, therefore have that cost is high, an inconvenient operation, defective that popularization degree is low.
Summary of the invention
The purpose of this utility model is to propose a kind of rotational flow separation, screen cloth separates the mud purification desander that combines.
The purpose of this utility model is achieved in that the mud purification desander comprises three filters, the I and II filter is comprised of the hydrocyclone of two series connection, it is fixed on upper rack, three-level filter device is vibrosieve, it is arranged on I and II filter below, frame lower.The bleed off pipe of one-level hydrocyclone is communicated with the inlet pipe of secondary hydrocyclone, and the sand removing hole of two hydrocyclones is over against the screen cloth middle part of vibrosieve.
Owing to implementing technique scheme, mud through the utility model after purifying, make the sand content in the mud reduce by 70%, the premium properties of mud is guaranteed, the average efficiency of rig-month has improved 21.3%, improve drilling efficiency, reduced the consumption of slush pump consumable accessory (cylinder sleeve, piston, valve body); Reduce the wearing and tearing of drilling rod, drilling tool, and reduced the consumption of pulping material, slurrying water, reduced mud cost 42.6%, reduced simultaneously useless slurry discharge value, alleviated environment pollution.
Description of drawings: concrete structure of the present utility model is provided by following drawings and Examples:
Fig. 1 is mud purification desander structural representation.
Legend: 1, hydrocyclone, 2, frame, 3, vibrating shaft, 4, the coarse meshed sieve net, 5, the detailed catalogue screen cloth, 6, guiding gutter, 7, spring, 8, vibrosieve, 9, motor.
The specific embodiment:
The utility model is not subjected to the restriction of following embodiment, can determine concrete embodiment according to the technical solution of the utility model and actual conditions.
Embodiment: as shown in Figure 1, the mud purification desander comprises three filters, and the I and II filter is comprised of the hydrocyclone 1 of two series connection, it is fixed on frame 2 tops, three-level filter device is vibrosieve 8, and it is arranged on I and II filter below, frame 2 bottoms.The bleed off pipe of one-level hydrocyclone is communicated with the inlet pipe of secondary hydrocyclone, and the sand removing hole of two hydrocyclones 1 is over against the screen cloth middle part of vibrosieve 8.
Hydrocyclone is technology, and it is arranged on the bleed off pipe of housing upper end by housing, is the inlet pipe that tangential direction is communicated with the housing circumference, and is arranged on the tumbler composition in the housing.Be divided into the cylindrical cavity on top and the conical cavity of bottom in the housing, the conical cavity lower ending opening is sand removing hole.Any hydrocyclone has certain solid particle separation diameter and cleanliness.For example, 60 microns of the particle separation diameters of a certain hydrocyclone, cleanliness 95% represents that namely this hydrocyclone can be isolating 95% greater than 60 microns solid.In the utility model, can select different hydrocyclones according to concrete instructions for use.
Vibrosieve 8 is by screen frame (unit), and be arranged on the interior screen cloth of screen frame (unit), and be arranged on guiding gutter 6 compositions under the screen cloth, crossed vibrating shaft 3 at the screen frame (unit) internal upper part, vibrating shaft 3 one sides are provided with the belt pulley that is equiped with eccentric block, and this belt pulley is driven by the motor 9 that is fixed on the frame 2.Vibrosieve 8 is seated at the base position on the frame 2, is connected with spring 7 between four jiaos of four jiaos of vibrosieve 8 bottoms and bases.The two-layer at least screen cloth of vibrosieve 8 inner tilings, from top to bottom sieve number increases progressively.When being two-layer screen cloth, the upper strata is coarse meshed sieve net 4, and lower floor is detailed catalogue screen cloth 5.
During mud purification, the hydrocyclone 1 of two series connection is separated into low-density overflow and highdensity underflow with mud, and wherein overflow is returned mud circulating system by the bleed off pipe of secondary hydrocyclone, and underflow drops on the vibrosieve 8.Subsequently, the upper strata coarse meshed sieve net of vibrosieve 84 is separated into two parts again with highdensity underflow, and a part is slurries and sees through coarse meshed sieve net 4 less than the particle of mesh and fall to detailed catalogue screen cloth 5; Another part is that the particle greater than mesh is discharged from from coarse meshed sieve net 4.At last, the slurries that lower floor's detailed catalogue screen cloth 5 of vibrosieve 8 will contain particle separate again, slurries and see through detailed catalogue screen cloth 5 less than the particle of mesh and return mud circulating system through guiding gutter 6; Another part is that the particle greater than mesh is discharged from from detailed catalogue screen cloth 5.
Above technical characterictic has consisted of most preferred embodiment of the present utility model, and it has stronger compliance and best implementation result, can increase and decrease according to actual needs inessential technical characterictic, satisfies the needs of different situations.
