Abstract
The utility model provides a horizontal well staged fracturing is with ground device of batting, including the storage bulb that is used for the temporary storage bowling, store up bulb lower part fixedly connected with and be arranged in dropping into the first ooff valve in the fracturing pipeline with storing up the bulb bowling, storage bulb upper portion fixedly connected with is used for packing the bowling into and stores up the second switch valve of bulb and pressure release, and the bowling device is still including connecting in the tee bend of first switch lower valve portion's T type. The utility model has the advantages of before the fracturing, the bowling of packing into in advance during the bowling operation, only needs to reduce the construction discharge capacity and to certain numerical value, opens first ooff valve, does not need the termination of pumping can accomplish the bowling operation, has guaranteed the continuity of construction, has improved the efficiency of construction of whole fracturing. In addition, the second switch valve has the pressure release function concurrently, does not need to set up in addition pressure relief device again for the compact structure of bowling device.
Description
Technical field
This utility model relates to a kind of staged fracturing of horizontal well ground ball-throwing apparatus.
Background technology
Open hole packer staged fracturing has become a kind of common staged fracturing of horizontal well technology the most, this technique ties up to enter tail pipe, packer and pitching sliding bush combination under in bore hole horizontal segment, use the mode completion of tail tube hanging, put into external diameter by well head during pressure break and become big bead successively and open pitching sliding sleeve at different levels and realize pressure break piecemeal.
Pitching at present mainly uses personnel in the mode of fracture well head main valve pitching, for ensureing personal security, typically need termination of pumping turn on pump construction again after pitching completes, construction so can be made discontinuous thus increase the activity duration, especially during multistage pressure break, carrying out repeatedly pitching, each pitching has certain time-consuming, thus affects the progress of whole fracturing process.
Utility model content
The purpose of this utility model is to provide a kind of staged fracturing of horizontal well ground ball-throwing apparatus, needs termination of pumping to cause construction discontinuously thus the problem affecting construction speed during to solve staged fracturing pitching in prior art.
In order to solve above-mentioned technical problem, this utility model adopts the following technical scheme that
A kind of staged fracturing of horizontal well ground ball-throwing apparatus, including for the interim storage bulb storing pitching, storage bulb bottom is fixedly connected with for pitching in storage bulb is put into the first switch valve in pressure break pipeline, and storage bulb top is fixedly connected with for pitching is loaded storage bulb and the second switch valve of pressure release.
Described ground ball-throwing apparatus also includes the T-shaped threeway being connected to the first switch valve bottom.
Described T-shaped threeway is positive threeway, and the arm of T-shaped threeway and the first switch valve are connected, and the supervisor of T-shaped threeway is connected in pressure break pipeline, and storage bulb is coaxially set with the arm of T-shaped threeway.
Described first switch valve and second switch valve are plug valve.
A length of 0.3 ~ the 0.5m of described storage bulb.
The beneficial effects of the utility model are: this ball-throwing apparatus includes the storage bulb storing pitching, control pitching put into the first switch valve of pipeline and control the second switch valve of dress ball, before pressing crack construction, it is previously charged into pitching, during pitching operation, only need to reduce operational discharge capacity to certain numerical value, open the first switch valve, need not termination of pumping and can complete pitching operation, it is ensured that the seriality of construction, improve the efficiency of construction of integral hydraulic fracturing.It addition, second switch valve has decompression function concurrently, it is not necessary to still further arrange pressure relief device so that the compact conformation of ball-throwing apparatus.
Accompanying drawing explanation
Fig. 1 is the structural representation of an embodiment of staged fracturing of horizontal well ground ball-throwing apparatus in this utility model.
In figure: 1.T type threeway；2. the first plug valve；3. storage bulb；4. the second plug valve.
Detailed description of the invention
As shown in Figure 1, staged fracturing of horizontal well ground ball-throwing apparatus includes for the interim storage bulb 3 storing pitching, storage bulb 3 bottom is fixedly connected with for pitching in storage bulb 3 is put into the first switch valve in pressure break pipeline, storage bulb 3 top is fixedly connected with for pitching is loaded storage bulb 3 and the second switch valve of pressure release, first switch valve and second switch valve are plug valve in this embodiment, the respectively first plug valve 2 and the second plug valve 4.Ground ball-throwing apparatus also includes the T-shaped threeway 1 being connected to the first plug valve 2 bottom, the most T-shaped threeway 1 is positive threeway, arm and first plug valve 2 of T-shaped threeway 1 are connected, the supervisor of T-shaped threeway 1 is connected in pressure break pipeline (not shown), and storage bulb 3 is coaxially set with the arm of T-shaped threeway 1.
When carrying out staged fracturing construction, before first paragraph pressure break (first paragraph is pressure reduction sliding sleeve, it is not necessary to pitching), in advance the pitching of second segment pressure break is positioned in storage bulb 3, only need to open the second plug valve 4 during dress ball, after dress chou bundle, close the second plug valve 4.Pressure break checks whether two plug valves are in closed mode before starting, by the normal pressure break of infusion program after confirming to close.Terminate in first paragraph pressure break, the when of preparing to put into second segment pressure break pitching, reduction operational discharge capacity to 1-2m3/ min, opens the first plug valve 2, makes pitching rely on gravity to naturally fall in the supervisor of T-shaped threeway 1 thus completes pitching operation.Close the first plug valve 2 afterwards, open the second plug valve 4 and first carry out pressure release, the 3rd section of pressure break pitching is put in storage bulb 3 after pressure releases, close the second plug valve 4, improve discharge capacity to designing discharge capacity, normal pressure break, circulated the most each section of pitching operation according to this.
The advantage using positive threeway is, pitching can rely on self gravitation to naturally fall in the supervisor of threeway, thus smoothly completes pitching operation, and pitching efficiency and success rate are higher.
In other embodiments of staged fracturing of horizontal well ground ball-throwing apparatus: the first switch valve and second switch valve can also be that other have the valve opening and closing function；After putting into second segment pressure break pitching, closing the first plug valve 2, the most i.e. can improve discharge capacity to design discharge capacity and carry out normal pressure break, then pressure break is while putting into the 3rd section of pressure break pitching, realizes the repeatedly pitching operation of staged fracturing by that analogy.
