Description
Technical field
The utility model relates to a kind of straight barrel type gas well surface line and catches ball device.
Background technology
Separate stratum fracfturing technology is non-conventional gas and oil resource exploitation, a kind of important means of oil-gas reservoir being carried out to fracture acidizing, and it is widely used in straight well, the directional well of shale gas, hyposmosis payzone, oil sheet, the fracturing yield increasing transformation of horizontal well.
What in prior art, commonly use is ball-throwing type separate stratum fracfturing technology, in whole work progress, need repeatedly in well, to throw in the ball that builds the pressure, after pressing crack construction finishes, unobstructed for reaching in well production fluid passage, all need to return and discharge the ball that builds the pressure dropping in well, in order to realize the row of returning smoothly of the ball that builds the pressure, conventionally well head caught to ball device or be positioned in well head, or being laterally connected on well head flank, then well site is returned comb Correspondent and is crossed well head and catch ball device and be connected to well head and adopt on oil/gas tree.
But this row's of returning mode exists because well head is caught ball device and is positioned in well head or is laterally arranged on well head flank, easily because shock falls in well again, causes and catches ball failure problem after the ball that builds the pressure is got rid of.
Utility model content
The purpose of this utility model is to provide a kind of straight barrel type gas well surface line and catches ball device, is vulnerable to clash into the problem of catching ball failure brought to solve the existing ball device of catching because of installation site and the ball that builds the pressure.
For this reason, the utility model provides a kind of straight barrel type gas well surface line to catch ball device, comprises a cylindrical shape pipeline section, is arranged on the seal cover of this pipeline section outer end and is arranged on the handle on sealing lid outer face, and described pipeline section surface is provided with multiple flowing holes.
Above-mentioned flowing hole comprises multiple macropores and multiple aperture, and the plurality of macropore evenly arranges along the axial and circumferential of described pipeline section, forms along the axially extended macropore row of pipeline section, along the circumferential macropore circle of pipeline section;
The plurality of aperture evenly arranges along the axial and circumferential of described pipeline section, forms along the axially extended aperture row of pipeline section, along the circumferential aperture circle of pipeline section;
Macropore row and aperture row are along the circumferential alternate setting of pipeline section; Macropore circle and aperture circle are along the axial alternate setting of pipeline section.
Above-mentioned aperture is placed in the foursquare center of the line formation of four macropores on adjacent macropore row.
The length of above-mentioned pipeline section is 710 millimeters to 810 millimeters, and internal diameter is 69.82 millimeters, and external diameter is 74.02 millimeters.
The diameter of above-mentioned macropore is 24.27 millimeters, and the diameter of aperture is 16.18 millimeters.
The beneficial effects of the utility model: realize the row of returning smoothly of the ball that builds the pressure, improve operating efficiency, in catching ball, ensure passing through smoothly of oil, do not affect the overall progress of the row's of returning operation, convenient and practical.
Below with reference to accompanying drawing, the utility model is described in further details.

Detailed description of the invention
Embodiment 1:
As shown in Figure 1, the present embodiment provides a kind of straight barrel type gas well surface line to catch ball device, comprise a cylindrical shape pipeline section 1, be arranged on the seal cover 2 of this pipeline section 1 outer end and be arranged on the handle 3 on sealing lid 2 outer faces, described pipeline section 1 surface is provided with multiple flowing holes 11, flowing hole 11 comprises multiple macropores 4 and multiple aperture 5, and the plurality of macropore 5 evenly arranges along the axial and circumferential of described pipeline section 1, form along the axially extended macropore row of pipeline section 1, along the circumferential macropore circle of pipeline section; The plurality of aperture 5 evenly arranges along the axial and circumferential of described pipeline section 1, forms along the axially extended aperture row of pipeline section 1, along the circumferential aperture circle of pipeline section 1; Macropore row and aperture row are along the circumferential alternate setting of pipeline section 1; Macropore circle and aperture circle are along the axial alternate setting of pipeline section 1, and aperture 5 is placed in the foursquare center of the line formation of four macropores 4 on adjacent macropore row.Like this in the intensity that ensures to have improved in aperture meets discharge opeing demand connector between hole, realized borehole fluid by time flow velocity unaffected, and catch ball device thickness Anti-erosion intensity and further improving application life fixing in the situation that.
The Main Function of flowing hole 11 be staged fracturing construction finish after when the row of returning borehole fluid, can make fluid pass through and not throttling through catching ball device flowing hole, build the pressure ball under the rolling action of borehole fluid, from tubing string, return out to catching in ball device that surface line is installed, the ball that builds the pressure was subject to after stopping of flowing hole, was caught ball device to catch, in operating process, do not need to close well head, realized the row's of the returning operation continuously of staged fracturing borehole fluid.
The length of pipeline section 1 is 710 millimeters to 810 millimeters, and internal diameter is 69.82 millimeters, and external diameter is 74.02 millimeters, and the diameter of macropore 4 is 24.27 millimeters, and the diameter of aperture 5 is 16.18 millimeters.
