Description
Technical field
The utility model relates to a kind of stifled ball throwing device of realizing multistage temporarily stifled multiple crack fracturing technique, belongs to oil reservoir multiple crack fracturing technical field.
Background technology
The ultra-low penetration oil reservoir has Compacted rock, poor properties, well yield is low and the fast characteristic of production decline.Multistage temporarily stifled multiple crack fracturing technique is to study according to the theory of volume fracturing, its principle is according to pressing off the large characteristics of interval liquid absorption, bring a certain amount of stifled ball into to pressing off interval with fracturing fluid, implement temporary transient shutoff, force fracturing fluid enter other do not press off the layer build the pressure, press off another perforated interval.So repeatedly carry out, until press off all intervals in the reservoir, reach the purpose that enlarges the earial drainage volume and improve well yield.
At present, realize that the multistage temporarily stifled ball dosing method of stifled multiple crack fracturing technique mainly adopts the special-purpose ball injector of temporarily stifled pressure break, its operating process is before the construction ball injector to be connected to well head, will block up the ball ball injector of packing into.In pressing crack construction, the constructor operates the ball injector pull bar, and the stifled ball below 100 is dropped in the well one by one.The constructor stands in well head higher-pressure region implementation and operation, and security risk is very large.The stifled ball quantity of packing into is few, adds number of times limited, can not farthest enlarge the earial drainage volume, improves well yield.Manually adding stifled ball can not the accurate-metering input quantity, adds speed discontinuous, inhomogeneous, affects very much the effect of multistage temporarily stifled multiple crack fracturing technique.
Summary of the invention
The purpose of this utility model is to provide a kind of stifled ball throwing device of realizing multistage temporarily stifled multiple crack fracturing technique, and it can realize that the Remote automatic feeding blocks up ball, improves temporarily stifled progression, enlarges the earial drainage volume and improves well yield.
Concrete technical scheme of the present utility model is as follows:
Be provided with helical axis in the fairlead of this stifled ball throwing device, the fairlead inwall is comprised of the axial semi arch barrel of ordered series of numbers, and the helical axis outer peripheral face is formed by semi arch spiral concave surface.The fairlead bottom connects the base threeway, and the upper end connects gland.The gland top is by rotating shaft auxiliary connection travelling gear.Auxiliary driving gear and main drive gear are connected with a joggle.Main drive gear connects planetary reduction gear and the fire-proof motor that is located on the fairlead outer peripheral face.
The beneficial effects of the utility model are as follows:
This device storage ball capacity large (nearly 400) can be realized repeatedly adding, and stifled progression is high temporarily; Can be by automatically, continuously and evenly pitching of setting program, automatically computing and demonstration ball count; Can be in the local implementation remote control away from the well head higher-pressure region, construction safety risk is low; Transmission performance is good, and efficient is up to 98%; Corrosion resistance and sealing performance are good; Device bearing strength high (operating pressure is 105MPa, and delivery test pressure is 120MPa), design safety factor is more than 3 times of operating pressure, and is safe.
Description of drawings
Fig. 1 is for realizing the stifled ball throwing device structural representation of multistage temporarily stifled multiple crack fracturing technique.
Fig. 2 is the guide sleeve structure schematic diagram.
Fig. 3 is the fairlead radial cross-section.
Fig. 4 is for realizing the stifled ball throwing device work schematic diagram of multistage temporarily stifled multiple crack fracturing technique.
The specific embodiment
With reference to Fig. 1 embodiment of the present utility model is further specified:
Embodiment:
This stifled ball throwing device is comprised of fire-proof motor 1, planetary reduction gear 2, main drive gear 3, auxiliary driving gear 4, rotating shaft 5, gland 6, fairlead 7, helical axis 8 and base threeway 9:
Be provided with helical axis 8 in the tubular fairlead 7, fairlead 7 inwalls are comprised of the axial semi arch barrel of ordered series of numbers, and helical axis 8 outer peripheral faces are formed by semi arch spiral concave surface.Fairlead 7 bottoms connect base threeway 8, and the upper end connects gland 6.Gland 6 tops are by rotating shaft 5 auxiliary connection travelling gears 4.Auxiliary driving gear 4 is connected with a joggle with main drive gear 3.Main drive gear 3 connects planetary reduction gear 2 and the fire-proof motor 1 that is located on fairlead 7 outer peripheral faces.
Because every row semi arch barrel of fairlead 7 inwalls and the semi arch spiral concave surface that helical axis 8 whenever revolves floor all can form the bead chamber, so, the Chu Qiuliang of fairlead 7 can significantly be increased.Along with the rotation of helical axis 8, stifled ball is advanced vertically by semi arch spiral concave surface, and the unit distance that stifled ball is advanced is the helical pitch that helical axis 8 rotates a circle.
Installation of the present utility model and the course of work are as follows:
Before the pressing crack construction, this stifled ball throwing device is fixed on well head 11, connects well head 11 and fracturing unit truck 10 by high pressure line.Long-distance control cabinet 12 is located at distance construction higher-pressure region 40m locates in addition, by sensing cable access 220V AC power.
In the fracturing process, fracturing fluid enters the measure oil well through fracturing unit truck 10, base threeway 8 and well head 11.In the time of need adding stifled ball, start long-distance control cabinet 12,1 work of instruction fire-proof motor, planetary reduction gear 2 reductions of speed drive main drive gear 3 and auxiliary driving gear 4 low cruises, drive rotating shaft 5 and fairlead 7 rotations.Along with the low speed rotation of fairlead 7, stifled ball falls into base threeway 8 one by one, enters the measure oil well with fracturing fluid.Meanwhile, long-distance control cabinet 12 can show the quantity that adds of stifled ball.Add finish after, added by long-distance control cabinet 12 instructions and to stop.
