Close borehole jack, perforate cover internal diameter more than or equal to top connection, lower contact internal diameter.Close the borehole jack outer wall and have groove, be provided with stopping mechanism in the groove.Close and adopt the seal sealing between borehole jack, perforate cover and body, the plug sleeve respectively.
The utility model major advantage is: perforate mechanism design simple in structure, unique, directly hydraulic pressure perforate; Need not after permanent hole, pass and the solid completion to bore sizing collar internal construction and ash plug, saved operation, reduced difficulty of construction.
Description of drawings
Fig. 1 the utility model structural representation
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described in further details.
The non-brill sizing collar of hydraulic pressure perforate as shown in Figure 1 mainly is made up of top connection 1, body 2, stopping mechanism 3, pass borehole jack 4, perforate cover 7, plug sleeve 9, lower contact 11 etc.Top connection 1, lower contact 11 are connected with body 2 upper and lower sides respectively.Pass borehole jack 4, perforate cover 7 are sheared dowel fixes respectively on body 2, and plug sleeve 9 is sheared dowel fixes and is closing on the borehole jack 4.Pass borehole jack 4, perforate cover 7 place body 2 inner chambers; Have cementing hole 6, pressure transmission hole 10 on the body 2.Plug sleeve 9 places and closes borehole jack 4,7 inner chambers are overlapped in perforate, has liquid flow hole 5 on the plug sleeve 9.Close borehole jack 4 and be positioned on the perforate cover 7, the cementing hole 6 on the body 2, the liquid flow hole 5 on the plug sleeve 9 are positioned at and close under the borehole jack 4, and to overlap 7 tops relative with perforate.Closing borehole jack 4 is up and down uniform cross-section.7 bottoms are overlapped in perforate the outer step surface of annular, and perforate is overlapped 7 bottom sections and overlapped cross section, 7 top less than perforate.There is step surface in the annular body 2 inside, and its position is the step surface below outside perforate cover 7 annulars.Perforate is overlapped the outer step surfaces of 7 bottoms, perforate cover, 7 annulars, body 2, the interior step surfaces of body 2 annulars and is surrounded pressure-releasing chamber 8, and the pressure transmission hole 10 on the body 2 is connected with pressure-releasing chamber 8.Upward annular interior step surface, following annular interior step surface are arranged in the plug sleeve 9, and upward annular interior step surface internal diameter size is greater than following annular interior step surface.
Pass borehole jack 4, perforate are overlapped 7 internal diameters more than or equal to top connection 1, lower contact 11 internal diameters.Close borehole jack 4 outer walls and have groove, be provided with stopping mechanism 3 in the groove.The stopping mechanism 3 that closes in borehole jack 4 grooves can adopt retaining steel ball or other forms, and is descending afterwards up again to prevent closing borehole jack 4.Close between borehole jack 4, perforate cover 7 and the body 2, close between borehole jack 4, perforate cover 7 and the plug sleeve 9 and adopt the seal sealing,, prevent that cement paste from missing in the gap of sizing collar instrument with the sealing at assurance cementing hole 6, liquid flow hole 5 two ends, increase descending resistance, avoid heavy corrosion.The seal that closes between borehole jack 4, perforate cover 7 and the body 2 can adopt the O RunddichtringO, and the seal that closes between borehole jack 4, perforate cover 7 and the plug sleeve 9 can adopt the rubber back-up ring.The shear pin of fixing glue plug sleeve 9 should be cut off after the shear pin of fixing pass borehole jack 4, and therefore, its intensity of the shear pin of fixing glue plug sleeve 9 should be greater than the fixing shear pin that closes borehole jack 4.
The utility model principle is: the non-brill sizing collar of hydraulic pressure perforate is inserted G.I.H in the completion tubular string, carry out the one-level well cementation earlier.After bruising finishes, continue to build the pressure to cutting off shear pin, perforate cover 7 moves down, and cementing hole 6 on the connection body and the liquid flow hole 5 on the plug sleeve are realized the hydraulic pressure perforate.Drop into bottom plug then in sleeve pipe, bottom plug walks in 9 times annulars of plug sleeve step surface and stops descendingly, carries out cementing job.Behind the cemented up, replace the slurry operation, when coming downwards on the plug sleeve 9 in the annular step surface for the slurry plug, pressure rises, and cuts off shear pin, closes borehole jack 4 and moves down with plug sleeve 9 and realize the hole, pass, and stopping mechanism 3 prevents to close borehole jack 4 and moves up.Continue to build the pressure, cut off shear pin, plug sleeve 9 falls into the shaft bottom with bottom plug and replacement plug.The non-brill sizing collar of hydraulic pressure perforate this moment minimum diameter is consistent with casing inner diameter, need not to bore sizing collar internal construction and ash plug.
