Abstract
The utility model belongs to a pitching machine of an oil-drilling device with air-lifting balls used for drilling a deep well, a directional well, a well with a high content of wax and a thick oil well in the oil industry. The shift-fork pitching machine for oil drilling with the air-lifting balls comprises a casing 1, a separation umbrella 2 for separating the air from the oil, an oil tank 3, a filtering net 4, a speed-adjusting motor 5 and a gear reduction mechanism 6. The center of the casing 1 is provided with a vertical shaft 7 which is connected with a driven gear 8, and the driven gear 8 is engaged with a driving gear 9. The vertical shaft 7 is provided with uniformly distributed shift forks 10 which are arranged above the filtering net. With the action of the shift forks, and not affected by the thickness of the crude oil, the air-lifting balls of the utility model can be uniformly pitched, so that the oil production efficiency is increased. The utility model is suitable for thick oil production.
Description
The utility model belongs to and is used to exploit the ball serving device that deep-well, directional well, particularly horizontal well, height close a kind of airlifting ball extracting device of oil of wax well, high temperature well, corrosion well, heavy oil wells in the petroleum industry.
At present both at home and abroad the gas-lift production mode of using has open type or half-closed continuous gas lift, the gaslift of half-closed gap, the gaslift of closed-type double action crank press packer chamber, the gaslift of plug-in type cavate, plunger type gaslift etc., these airlift units are because slippage loss is big, cause gas injection than big, operating pressure and starting pressure height, start gas consumption big, start slow, unit efficiency is low.The particularly former oil reservoir of horizontal wells hyposmosis, heavy oil tested layer, other mechanical oil recovery device can't descend horizontal segment or deep camber section, though and general gas-lift production device can descend horizontal segment because the oil gas Gravity Separation loses and pushes away oil and act on.For this reason, Chinese patent 90209934.5 and 94211885.5 proposes a kind of airlifting ball gas-lift production method and ball control device thereof that utilizes the waterwheel principle, continuous input airlifting ball is arranged in lift tube, eliminate oil recovery slippage loss, gas injection is reduced than at double, the down-hole need not accurate gas lift valve, and the oil recovery degree of depth is big, can be used for ultradeep well, low fluid level well and make device can descend horizontal segment or deep camber section.
But the screw mechanism that the ball serving device in the technical scheme that above-mentioned patent proposes adopts card ball and slimeball easily when viscosity of crude is big, the speed of influence service and at interval can not normally be carried out oil recovery.
The purpose of this utility model provides a kind of shift fork that uses in ball serving device, the airlifting ball oil recovery shift fork ball serving device that airlifting ball can normally be sent when viscosity of crude is big.
Scheme of the present utility model is: airlifting ball gas-lift production shift fork ball serving device comprises housing 1, gas-liquid separation umbrella 2, oil groove 3, filter screen 4, buncher 5, gear reduction 6, there is a vertical axis 7 at the center in the housing 1, vertical axis 7 is connected with driven gear 8, moving gear 8 and driving gear 9 engagements, uniform shift fork 10 is housed on vertical axis 7, and shift fork 10 is positioned at the top of filter screen.
Other scheme of the present utility model is: an end of shift fork 10 is connected with shift fork head 11.Filter screen 4 is circular, and is fixed on the inwall of housing 1, and the bottom opening of filter screen 4 links to each other with excessive cone ports 12, and cone ports 12 is communicated with passage 13, and passage 13 corners are rounding off.Shift fork head 11 is spheroidal or elongated cylindrical, and facing two shift fork heads, 11 gaps mutually is 1.2-1.5 airlifting ball diameter doubly.
Advantage of the present utility model is: because the effect of shifting fork mechanism, airlifting ball can evenly not sent by the influence of viscosity of crude, has improved oil recovery efficiency, is applicable to thickened oil recovery.
The utility model description of drawings is as follows:
Fig. 1 is an airlifting ball gas-lift production shift fork ball serving device schematic diagram;
Fig. 2 is another embodiment schematic diagram of airlifting ball gas-lift production shift fork ball serving device;
Fig. 3 is the schematic diagram of the utility model shift fork;
Fig. 4 is another embodiment schematic diagram of the utility model shift fork.
Below in conjunction with accompanying drawing the utility model is described further:
Airlifting ball gas-lift production shift fork ball serving device comprises housing 1, gas-liquid separation umbrella 2, oil groove 3, filter screen 4, buncher 5, gear reduction 6, there is a vertical axis 7 at the center in housing 1, vertical axis 7 is connected with driven gear 8, driven gear 8 and driving gear 9 engagements can rotate under the drive of buncher 5, gear reduction 6.Be equipped with on the vertical axis 7 to put and establish the uniform shift fork of shape 10, shift fork 10 can be around circular motion above filter screen 4.
One end of shift fork 10 is connected with shift fork head 11, and shift fork head 11 can be placed in the outside or the inboard of shift fork 10 as required, and shift fork head 11 is spheroidal or elongated cylindrical, and facing two shift fork heads, 11 gaps mutually is 1.2-1.5 airlifting ball diameter doubly.Filter screen 4 is circular taper, and is fixed on the inwall of housing 1, and the bottom opening of filter screen 4 links to each other with excessive cone ports 12, and cone ports 12 is communicated with passage 13, and passage 13 corners are rounding off.When shift fork 10 above the filter screen 4 during around circular motion, the airlifting ball that drops on the filter screen also moves in a circle thereupon, the airlifting ball of the bottom opening top of filter screen 4 can enter excessive cone ports 12, sends from passage 13 under pressure, and passage 13 corners are that rounding off is in order not block ball.
