Abstract
A slurry mixing tank provided with a weir flow plate comprises a tank body and a plurality of stirrers. One end of each stirrer is arranged on the top of the tank body, and the other end of each stirrer extends into the tank body. The slurry mixing tank is characterized in that the weir flow plate is arranged in the tank body, the bottom of the weir flow plate is connected with the tank body and partitions the tank body into a slurry mixing compartment and an equalizing compartment, and the upper edge of the weir flow plate is lower than the top of the tank body. The slurry mixing tank has the unique advantages that slurry obtained through the slurry mixing tank by mixing is more uniform and constant in density.
Description
Technical field
The present invention relates to a kind of oil drilling and extracting equipment, particularly a kind of slurry mixing tank with weir flow plate.
Background technology
Quality of mud fluid requirement needed for Cementing operation mixes, density constant fluctuation is little, and this is directly connected to the effect of well cementing operation.In existing mixed slurry technology, high energy mixers rapid mixing water and ash in mixed slurry system, the agitator through slurry mixing tank is of short duration to be uniformly mixed, and final high pressure infusion is to down-hole.Because mixing velocity fast, the resident slurry mixing tank time is short, the gas mixed in uneven, mud does not fully overflow, and mud density is fluctuated large, causes quality of mud fluid to be difficult to reach the requirement of well cementing operation.
Summary of the invention
The object of the present invention is to provide a kind of slurry mixing tank with weir flow plate, the mud using this slurry mixing tank to blend is more even, density constant.
The technical scheme realizing the object of the invention is: a kind of slurry mixing tank with weir flow plate, comprise tank body and some agitators, described agitator one end is arranged on the tank body top other end and extends in tank body, it is characterized in that: there is in described tank body weir flow plate, the bottom of the weir flow plate be somebody's turn to do connects with tank body and is divided into by tank body mixed starches compartment and balanced compartment, and the upper limb of described weir flow plate is lower than the top of tank body.
And there is between the upper limb of described weir flow plate and tank body top the gap of 10 ~ 30 centimetres.
And the plane of described weir flow plate has flanging or wave channel.
And the angle of described flanging or wave channel is 60 ~ 90 °, the edge of described flanging or wave channel is 5 ~ 15 centimetres to the distance of weir flow board plane.
And described balanced compartment is greater than 2 with the mixed volume ratio ratio starching compartment.
And the bottom surface of described mixed slurry compartment is inclined-plane, have a circulation port and this mixed starch compartment and be communicated with.
And the bottom surface of described balanced compartment is inclined-plane, outlet opening compartment balanced with this is had to be communicated with.
The invention has the advantages that: adopt the balanced compartment of large volume to increase the residence time of mud, the unhurried current with no pressure that weir flow plate is formed can overflow the gas in mud, weir flow plate surface flanging or wave channel are eliminated mud and are turned round and round, form upper and lower axial flow, mud is fully mixed, realizes the equilibrium of mud density.

Detailed description of the invention
see Fig. 1 ~ 4, below with reference to embodiment, the present invention will be further described.
A kind of oil drilling and extracting equipment, particularly a kind of slurry mixing tank with weir flow plate, comprise tank body 1 and some agitators 5, described agitator 5 one end is arranged on the tank body 1 top other end and extends in tank body 1, it is characterized in that: in described tank body 1, there is weir flow plate 2, the bottom of the weir flow plate 2 be somebody's turn to do connects with tank body 1 and is divided into by tank body 1 mixed starch compartment 3 and balanced compartment 4, and the upper limb of described weir flow plate 2 is lower than the top of tank body 1.
Mixed slurry compartment 3 carries out the cement paste just mixed slurry of mixed circulation secondary, and balanced compartment 4 accepts just mixed cement paste and fully stirs (echelon) further, and the cement paste of balanced compartment 4 is not substantially by the influence of fluctuations of mixed slurry compartment 3.
And there is between the upper limb of described weir flow plate 2 and tank body 1 top the gap of 10 ~ 30 centimetres.
Mixed slurry compartment 3 and balanced compartment 4 are separated by weir flow plate 2, force the cement paste of mixed slurry compartment 3 from weir flow plate 2, balanced compartment 4 can only be flowed in edge, upstream is choked water formation unhurried current with no pressure and is entered balanced compartment 4, the flowing of this weir flow slowly, liquid level wide (width of compartment) depth as shallow (along the distance to free surface on weir flow plate) is without pressure (free surface, depth as shallow), the mud scope of freedom fully with extraneous contact, a large amount of gas overflows from mud, realizes mud degasification.
And the plane of described weir flow plate 2 has flanging or wave channel.
The surperficial flanging of weir flow plate 2 or wave channel, can strengthen described weir flow plate 2 on the one hand and make and working strength, can change into radial and axial flowing on the other hand by tangentially flowing, eliminate whirlpool, increase less turbulence, form the Homogeneous phase mixing of full compartment mud, and incrustation easily cleans.
Further technical scheme can be the angle of described flanging or wave channel is 60 ~ 90 °, and the edge of described flanging or wave channel is 5 ~ 15 centimetres to the distance of weir flow board plane.
Under the flanging of weir flow plate 2 or the effect of wave channel, cement paste forms radial and axial flowing, this upper and lower axial flow one levels mud convection current in tank can be mixed, two is in lower floor's mud upwards process, gas contained by cement paste is brought to cement paste free surface, realizes its spilling with no pressure.
And described balanced compartment 4 is greater than 2 with the mixed volume ratio ratio starching compartment 3.
Adopt little mixed slurry compartment 3, increase large balanced compartment 4, the mode that cement paste echelon stirs, achieve slurry mixing tank volume substantially constant, and cement paste residence time, mixing evenly, gas overflowing is more abundant.
And the bottom surface of described mixed slurry compartment 3 is inclined-plane, have a circulation port 6 and this mixed starch compartment 3 and be communicated with.
Part mud reenters high energy mixers through circulation port 6 and mixes, and forms the mixed slurry of secondary, recycling back-mixing slurry compartment 3, can mud be made evenly.
Further technical scheme also can be the bottom surface of described balanced compartment 4 is inclined-plane, has an outlet opening 7 compartment 4 balanced with this to be communicated with.
Mix complete mud and be discharged into high pressure pumping-in equipment through outlet opening, for Cementing operation.
The present invention is in the utility model patent with regard to same subject application on the same day.
