The device consists of a soluble ball 1, a central tube 2, a push ring 3, a split type slip 4, a hoop 5, a cone 6, a protective copper ring 7, a rubber cylinder 8 and a guide joint 9, wherein the central tube 2 is sequentially connected with the push ring 3, the split type slip 4, the cone 6, the protective copper ring 7, the rubber cylinder 8, the protective copper ring 7, the cone 6, the split type slip 4 and the guide joint 9 from top to bottom; the invention has the advantages of simple structure, high bearing capacity, strong adaptability, fast drilling and milling, large drift diameter, light weight and the like.
Description
Technical field
The present invention relates to oil extraction in oil field field of engineering technology, belong to a kind of high pressure resistant high temperature of horizontal well extensive volume fracturing transformation, bore the pressure break big orifice speed brill bridging plug that milling is fast, big orifice, quality are light.
Background technology
Routine can be bored bridging plug and the setting accident in midway is easily occurred, and quality is comparatively large, and milling difficulty, is not suitable for high angle hole, horizontal well.At present, due to its structure of bridging plug, properties of materials restriction, the big orifice speed not also being applied to the transformation of horizontal well multistage massive hydraulic fracture bores bridging plug.
Summary of the invention
After the object of this invention is to provide a kind of construction, directly can to go into operation operation for producing well, and be applicable to the pressure break big orifice speed brill bridging plug of oil gas horizontal well reservoir fracturing improvement construction.
The big orifice speed that the present invention relates to bores bridging plug, it is made up of solvable ball, central tube, throw-out collar, split-type slips, garter spring, cone, protection copper ring, packing element and guide sub, and wherein central tube connects throw-out collar, split-type slips, cone, protection copper ring, packing element, packing element, protection copper ring, cone, split-type slips, guide sub from top to bottom successively; Split-type slips is made up of multiple slip segment, each slip segment has hoop groove, and split-type slips is fixed on multiple slip segment on central tube by garter spring; Central tube bottom is with male thread, and guide sub connects the male thread of central tube bottom by box thread.
Packing element is quality of rubber materials, and garter spring is nylon fiber material, and remaining part is alloy material.
Inner diameter of centerpipe is φ 50mm-φ 60mm.
Solvable ball to have under fracturing fluid and wellbore fluid effect consoluet characteristic in certain hour.
Guide sub has the bridging plug multistage milling docking anti-rotation face of 40 °-65 °.
The present invention compared with the prior art tool has the following advantages:
1) adopt alloy material, bridging plug is had, and bearing capacity is high, strong adaptability, brill milling is fast, latus rectum is large and quality is light feature.
2) for huge discharge producing well, can directly go into operation after pressure break.
accompanying drawing illustrates:fig. 1 is structural representation of the present invention.
Fig. 1: 1-solvable ball, 2-central tube, 3-throw-out collar, 4-split-type slips, 5-garter spring, 6-cone, 7-protects copper ring, 8-packing element, 9-guide sub.
detailed description of the invention:below in conjunction with accompanying drawing, the invention will be further described: it is made up of solvable ball 1, central tube 2, throw-out collar 3, split-type slips 4, garter spring 5, cone 6, protection copper ring 7, packing element 8 and guide sub 9, and wherein central tube 2 connects throw-out collar 3, split-type slips 4, cone 6, protection copper ring 7, packing element 8, packing element 8, protection copper ring 7, cone 6, split-type slips 4, guide sub 9 from top to bottom successively; Split-type slips 4 is made up of multiple slip segment, each slip segment has hoop groove, and split-type slips 4 is fixed on multiple slip segment on central tube 2 by garter spring 5; Central tube 2 bottom is with male thread, and guide sub 9 connects the male thread of central tube 2 bottom by box thread.
Packing element 8 is quality of rubber materials, and garter spring 5 is nylon fiber material, and remaining part is alloy material, and this alloy material has good brill milling performance.
Inner diameter of centerpipe is φ 50mm-φ 60mm.
Solvable ball 1 to have under fracturing fluid and wellbore fluid effect consoluet characteristic in certain hour.
Guide sub 9 has the bridging plug multistage milling docking anti-rotation face of 40 °-65 °.
During onsite application, utilize cable to send the present invention and setting tool, after arriving horizontal segment, surface pump pressurizes, and promotes the present invention and arrives predeterminated level section.Activate cable setting tool; throw-out collar 3 under setting instrument urceolus; throw-out collar 3 promotes split-type slips 4 and moves down along cone 6 and strut; cone 6 moves down and promotes to protect copper ring 7 to compress packing element 8; simultaneously packing element 8 continues to move down and promotes bottom protection copper ring 7 and bottom cone 6 moves down, and bottom cone 5 compresses lower part flap-type slips 4, and split-type slips 4 struts; be subject to compression swelling at the effect lower rubber cylinder 8 of thrust, reach the object of shutoff casing annulus.Split-type slips 4 is strutted by cone 6 further simultaneously, is stuck in internal surface of sleeve pipe.Set Process-centric pipe 2 tension, when stressed acquiring a certain degree, the shear pin in central tube 2 pin hole is pulled off, and completes of the present invention setting and give up, realizes the packing of pressing crack construction reservoir.Take out cable and setting tool, well head drops into solvable ball 1, when ball enters horizontal segment, takes a seat with the solvable ball 1 of small displacement pumping, after playing pressure, carries out relevant fracturing reform construction.
