Abstract
The landwaste gathering-device being applicable to gas drilling belongs to an oil drill equipment field, its objective is the way adopting machinery to be separated, and is separated the landwaste composition in biased sample and gas componant.The utility model is made up of entrance cabin, entrance, multistage filter plate, outlet cabin, cover plate, outlet, axis of rotation, left-handed blade, dextrorotation blade, landwaste disposable box, cover plate is at the top in outlet cabin, entrance cabin is in the lower end in outlet cabin, landwaste disposable box is in the bottom in entrance cabin, separated by multistage filter plate in the middle of outlet cabin and entrance cabin, axis of rotation is positioned at the axial centre in outlet cabin and entrance cabin.Left-handed blade is that 30 degree of angle of slope are welded on axis of rotation top, and blade increases in cross section from top to bottom gradually.Dextrorotation blade is that 30 degree of angle of slope are welded on axis of rotation bottom, and blade reduces in cross section from top to bottom gradually.The utility model avoids the defect that aqueous medium is separated, and ensure that the authenticity of the gaseous sample after separation.
Description
Technical field
The utility model relates to a kind of device collecting landwaste, and the device of particularly a kind of gas drilling landwaste collection, belongs to oil drill equipment field.
Background technology
Under gas drilling condition, the landwaste being broken into floury in pit shaft, under gas circulatory mediator carries, is mixed into sediment outflow pipeline, brings puzzlement to log data collection.Need a kind of landwaste gathering-device being applicable to gas drilling, the representative good chip sample meeting well logging demand can be collected, the gaseous sample of relatively clean representative formation fluid can be isolated again.
On-the-spot landwaste is collected and is mainly used water as separating medium carries out gas solid separation.If application number is the Chinese patent of CN201410217334.4, disclose a kind of gas drilling landwaste separation method, its main feature is: the water circulation in whole system is flowed and after reaching balance, starts gas and creep into; In creeping into, the gas returned out from well head and solid are mixed to form fluid-mixing with recirculated water before separation, make the dust in solid be dissolved in water, progressively remove solid particle by tertiary treatment.Above-mentioned technology is comparatively complicated, needs water circulation and landwaste drying and dehydrating.Meanwhile, after adding water, the CO in gaseous sample
2, H
2s can be water-soluble thus cause damage, and makes the distortion of compound logging gas detect result, also do not utilize drilling safety.
Summary of the invention
The purpose of this utility model is to provide a kind of landwaste gathering-device being applicable to gas drilling, utilize the physical property difference of gas in biased sample, solid state component, adopt the way that machinery is separated, be separated the landwaste composition in biased sample and gas componant, the reset condition of better maintenance landwaste, ensure the authenticity of the gaseous sample after being separated, meet well logging demand.
The purpose of this utility model is realized by following proposal: a kind of landwaste gathering-device being applicable to gas drilling, be made up of entrance cabin, entrance, multistage filter plate, outlet cabin, cover plate, outlet, axis of rotation, left-handed blade, dextrorotation blade, landwaste disposable box, it is characterized in that: cover plate is at the top in outlet cabin, entrance cabin is in the lower end in outlet cabin, landwaste disposable box is in the bottom in entrance cabin, separated by multistage filter plate in the middle of outlet cabin and entrance cabin, axis of rotation is positioned at the axial centre in outlet cabin and entrance cabin.
Described a kind of landwaste gathering-device being applicable to gas drilling, is characterized in that: left-handed blade is that 30 degree of angle of slope are welded on axis of rotation top, and blade increases in cross section from top to bottom gradually.
Described a kind of landwaste gathering-device being applicable to gas drilling, is characterized in that: dextrorotation blade is that 30 degree of angle of slope are welded on axis of rotation bottom, and blade reduces in cross section from top to bottom gradually.
Described a kind of landwaste gathering-device being applicable to gas drilling, is characterized in that: entrance cabin and outlet cabin are that axial symmetry is cylindric, and adopt the anti-high pressure nonmetals of Anti-erosion to make.
The beneficial effects of the utility model are: adopt mechanical separation principle, avoid the defect that aqueous medium is separated, and gaseous sample composition soluble in water does not does not scatter and disappear, and maintain the reset condition of landwaste and gaseous sample, landwaste process is simple.

In figure: 1. entrance cabin; 2. entrance; 3. multistage filter plate; 4. export cabin; 5. cover plate; 6. export; 7. axis of rotation; 8. left-handed blade; 9. dextrorotation blade; 10. landwaste disposable box.
Detailed description of the invention
Below in conjunction with specific embodiment, be described further with regard to the utility model.Accompanying drawing can be used as the internal construction schematic diagram of the present embodiment.
Whole device is separated to form the outlet cabin (4) on top and the entrance cabin (1) of bottom by multistage filter plate (3), entrance cabin (1) and outlet cabin (4) are axial symmetry cylindrical shape, outlet (6) is positioned at cover plate (5) top, entrance (2) is positioned at the top side in entrance cabin (1), entrance (2) is connected with exterior tubing by gas-tight thread with outlet (6), and landwaste disposable box (10) is threaded connection with bottom, entrance cabin (1).
Turning cylinder (7) is positioned at the center of whole device, freely can rotate under the effect taking bits gas shock blade.It is inner that left-handed blade (8) is positioned at outlet cabin (4), be welded on axis of rotation (7) top, and blade increases in cross section gradually, in inverted cone shape in 30 degree of angle of slope from top to bottom; It is inner that dextrorotation blade (9) is positioned at entrance cabin (1), be welded on axis of rotation (7) bottom, and blade reduces in cross section gradually, in taper in 30 degree of angle of slope from top to bottom.
The journal bearing being lined with shaft seal is installed down in the junction of multistage filter plate (3) and turning cylinder (7), the journal bearing being lined with shaft seal is installed down in the junction of cover plate (5) same to turning cylinder (7), and cover plate (5) is bolted to connection with outlet cabin (4) housing.
When the landwaste that gas drilling carries out sieve residue log collects operation, the gas containing drilling cuttings that shaft bottom is returned out enters in entrance cabin (1) by entrance (2), powerful gas shock is on dextrorotation blade (9), blade turns clockwise under the effect of inclination angle and eddy flow, and drive turning cylinder (7) to rotate by journal bearing, dextrorotation blade (9) is under the transmission of downward force and the acting in conjunction of cutting grain weight, and cutting grain is pushed in the landwaste disposable box (10) of bottom, entrance cabin (1); Mix gas componant in sample after entering entrance cabin (1) by entrance (2), due to the reduction of flow velocity and the effect of blade, gas componant is separated with landwaste, rise through multistage filter plate (3) to filter, enter in outlet cabin (4), under the rotating flow guidance effect of the left-handed blade (8) in outlet cabin (4), pump drainage is also accelerated gas continuation moves, and arrives outlet (6) and discharges.The utility model utilizes blade to guide landwaste and the flow direction containing micronic dust gas, maintains the reset condition of landwaste and gaseous sample, is beneficial to the fidelity of well logging sample data, have the simple feature of structure simultaneously.
