Description

The mud solid phase separation equipment
Technical field
The utility model relates to a kind of mud solid phase separation equipment, belongs to the petroleum drilling engineering technical field.
Background technology
Drilling fluid, be commonly called as mud, to be used for balancing layer pressure in the oil drilling industry, to keep wellbore stability, will to creep into a kind of fluid that the landwaste that produces carries out well head simultaneously, increase along with drilling depth, increasingly various for different stratum and the required drilling fluid kind of operating mode, drilling fluid shared ratio in cost of drilling engineering is increasing, and its expense accounts for about 10% of drilling well total cost, be the most important thing of saving drilling cost so can annular use drilling fluid.
The oil drilling industry adopts the equipment such as vibrosieve, desander, desilter, centrifuge that the useless solid phase in the drilling fluid is separated removing at present.But because its clastotype that adopts is subject to technical limitations, so have to adopt plurality of devices to be used in combination the purpose that realizes that landwaste separates.
Currently used mud solid phase isolation technics, process is loaded down with trivial details, relevant device is more, personnel operation is loaded down with trivial details, maintenance cost is high, and the process processing time is longer, and needs the attached flow process tank of configuration just can operate, simultaneously processing region is because the factor such as the quantity of vibration equipment and pump is more, and noise and pernicious gas etc. causes working environment quite abominable.
The utility model content
The purpose of this utility model provides a kind of rational in infrastructure simple and easy, good separating effect, the mud solid phase separation equipment that cost is low.
For achieving the above object, the technical solution adopted in the utility model is: a kind of mud solid phase separation equipment, comprise pedestal, dashpot, circular screen, screen cloth backing roll, vacuum draw funnel, screen cloth driven roller, bearing support, air knife, Timing Belt and synchronous pulley, it is characterized in that: dashpot is installed on the base by bolt, the screen cloth backing roll is installed to the bottom of pedestal by bearing support, the screen cloth driven roller is installed in the top of screen cloth backing roll by bearing support, and circular screen walks around the screen cloth backing roll and driven roller is installed in the pedestal; Synchronous pulley is installed in an end of screen cloth driven roller and screen cloth backing roll; Timing Belt is installed on the synchronous pulley; The vacuum draw funnel is installed in the inside of circular screen; Air knife passes mounting blocks, is bolted the wire side both sides in circular screen, is used for the cleaning of screen cloth wire side; The axial end sealing of air knife, the other end is provided with snap joint, connects compressed air gas source; Air knife radially have several sections slits that width is less, be used for compressed air spraying to screen cloth;
The upper surface of vacuum draw funnel works to support upper screen with diagonal bar, and the vacuum draw funnel is provided with two openings simultaneously, is respectively the vacuum pump access port, is used for installing the vacuum pump suction inlet; The delivery pump access port is used for installing the delivery pump suction inlet;
Circular screen comprises driving-belt, screen cloth; The screen cloth both sides are connected with driving-belt respectively, become as a whole, and the screen cloth side is imbedded in the middle of the conveyer belt or in the combination of conveyer belt upper surface.Circular screen adopts the global formation pattern, namely is prefabricated into the screen cloth band of closed hoop.
During mud solid phase separation equipment overall operation of the present utility model, drilling fluid flows out from dashpot and falls into circular screen, and circular screen is rotarily driven by driven roller and synchronous pulley; The vacuum draw funnel is owing to linking vacuum pump, to produce at the screen cloth position local decompression, and then with the liquid phase in the drilling fluid, embed gas and can be sucked in the lump by the solid phase of screen cloth the vacuum draw funnel inner, liquid bulk accumulates to the certain altitude to be taken away to be discharged into by delivery pump and formulates zone or process tank in the funnel, but the gas of vacuum pump suction then is discharged into the safety discharge areas by filter; Under the motion of the useless solid phases such as landwaste at screen cloth that circular screen sieves out in the front portion of equipment because deadweight is fallen, the solid phase particles that does not break away from screen cloth is realized under the winding-up effect of air knife and the disengaging of screen cloth; When the drilling fluid treating capacity is in the apparatus settings scope, can carry out according to the size of flow the adjusting of the screen cloth speed of service, to reach optimum separating effect.
Mud solid phase separation equipment beneficial effect of the present utility model is:
1, changed the present situation that traditional plurality of devices is used in combination, so that a tractor serves several purposes; By changing screen cloth, can realize that landwaste screening, useful solid phase collect multiple needs such as (such as barites etc.), reduce equipment investment, reduce cost;
2, equipment life is stable, because adopted the pattern of vacuum draw and circular screen, equipment self has not had the vibrations of vibrosieve, the wearing and tearing of water conservancy cyclone, only need to can realize to the replacing that screen cloth is correlated with the maintenance of equipment, time saving and energy saving, the equipment body structure can be used for many years;
3, the pattern of the fixed screen cloth in blocks of traditional vibrosieve is changed in the innovation of screen cloth Installation Modes, adopts the screen cloth of annular action, separates on the one hand landwaste, transports on the one hand landwaste, good separating effect.
