Description
Technical field
The present invention relates to a kind of straight barrel type gas well surface line and catch 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 transformation of the fracturing yield increasing 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.
Summary of the invention
The object of this invention is to provide a kind of straight barrel type gas well surface line and catch ball device, to solve the existing ball device of catching, be vulnerable to clash into the problem of catching ball failure bring because of installation site and the ball that builds the pressure.
For this reason, the invention provides a kind of straight barrel type gas well surface line and catch ball device, comprise a cylindrical shape pipeline section, be arranged on the seal cover of this pipeline section outer end and be arranged on the handle on sealing lid outer face, described pipeline section surface is provided with a plurality of flowing holes.
Above-mentioned flowing hole comprises a plurality of macropores and a plurality of aperture, and the plurality of macropore evenly arranges along the axial and circumferential of described pipeline section, forms axially extended macropore row along 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 axially extended aperture row along 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.
Beneficial effect of the present invention: realize the row of returning smoothly of the ball that builds the pressure, improve operating efficiency, when catching ball, guarantee 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 present invention is described in further details.
