Detailed description of the invention
Be described in detail below in conjunction with the preferred embodiment of accompanying drawing to mud conditioning device of the present invention.
See accompanying drawing 1, mud conditioning device comprises slurry tank, heat preservation tank and heating system substantially.Slurry tank adopts common thickening tin or stainless cylinder of steel, its volume should meet the needs of shield slurry, and there is certain surplus, as volume is not enough, the cool mode of multiple can ice can be taked to solve, slurry tank is arranged in heat preservation tank, heat preservation tank is made up of concrete or sun-dried mud brick, but at least should possess certain intensity, prevent feedback broken, its wall thickness should not be less than 0.5m, the inside of heat preservation tank arranges oil resistant heat insulating and corrosion layer, as oil resistant resin plate etc., prevent heat to scatter and disappear in air and improve the bulk strength of heat preservation tank, heating system mainly comprises heating tube and heater, heater is used for heat medium and carries in heating tube, heating tube is arranged around slurry tank, preferred employing helical heating pipe, be coiled on tank body, helical heating pipe and tank body keep at a certain distance away and arrange, its first in heating and thermal insulation groove around the liquid oil of slurry tank filling, then gone forward side by side by liquid oil heating tank body and heat mud, avoid the too low various problems brought of mud temperature under psychro-environment.
Heat preservation tank is provided with liquid oil entrance and liquid oil outlet, for injecting respectively in heat preservation tank and drawing the liquid oil for protecting mild heat, slurry tank comprises tank body and end cap, end cap is provided with mud entrance, observation panel, agitator entrance and gas vent, the middle part of tank body is on the lower side is provided with slurry outlet, positive bottom is provided with the outlet of slag stone, wherein mud entrance and slurry outlet are respectively used to pour in tank body and draw mud, slurry outlet is with proportional valve, can determine as required export mud number, the position of slag stone outlet is in the below of slurry outlet, for draw through precipitation a large amount of sandstone and dense thickened drilling fluid, play diluting effect, ensure the quality of mud, reduce the addition of replenisher, observation panel is used for staff to be observed the mud situation in slurry tank and further operates as the case may be, when mud circulation is suspended or flow reduces, mud may excessively precipitate, block slurry outlet, now can insert mixing plant in agitator entrance, carry out artificial or mechanical rotation, mud circulation can be proceeded, mud in mud circulation is inevitably with some gases, once heating or stirring, these gases may will be separated out from mud, gas a large amount of is for a long time deposited in tank body, just may increase the pressure in tank body, bring danger, now, can by simply opening the valve on gas vent, realize quick pressure releasing.
Heating is one of most important function of this device, and mud composition situation is complicated, and mud all can quickly through tank body under normal circumstances, if heating slowly, heating-up temperature after mud passes through is too low, does not have heat effect, if heat too fast, mud heats up too high, wherein each kind of material just may react, and is deposited in tank wall, causes corrosion and blocks, therefore, a rational heating mode must be determined according to flow and temperature.With regard to the present embodiment, it adopts mode to helical heating pipe heated fluid injection by liquid oil indirect heating, therefore the mud rate of heat addition can be controlled easily by the amount controlling heated fluid injection, according to the actual conditions of device in heat-conduction principle and the present embodiment, and the acceptable mud temperature scope of shield structure, following approximate formula can be obtained:
In formula: H
s---the speed (m of heated fluid injection
3/ min);
