Description
Technical field
The present invention relates to sand control technologies, specifically a kind of that well is not stayed to be anchored sand proof packing tool.
Background technique
25, the developed loose sand oil field of Shengli Oil Field at present accounts for the 36.76% of oil field sum, yearly rate-oil production 949
Ten thousand tons, account for the 35.7% of the total oil production in oil field.The exploitation for doing loose sand oil accumulation well has oil field long term stable production important
Meaning.One of the foundation engineering that sand-preventing process is developed as loose sand oil accumulation, always through the entire exploitation of Shengli Oil Field
Course.The leading anti-sand process technology of Shengli Oil Field can be divided into mechanical sand control and chemical sand control two major classes up to now, mechanical
Sand control technique can account for 70% or more of whole sand control technique applications.Important composition of the packing tool as mechanical sand control technology
Part, current sand proof packing tool can be divided into two classes, i.e., with anchoring with without anchoring.Packing tool with anchoring is in sand control
It can be anchored sand control pipe when filling construction, prevent tubing string from wriggling above and below, improve the security reliability of construction；Without anchoring
Packing tool is commonly applied in shallow well, and the scope of application is small.Sand proof packing tool is after filling anti-sand is constructed at present, generally all
It is stayed in well with sand control pipe, only can rise with sand control pipe (or independent) until lower subjob, and normal machine
The tool sand control life, therefore, when salvaging, it is difficult that the sand control pipe with anchoring often results in salvaging generally in two-and-a-half years or so.
Summary of the invention
The purpose of the present invention is in view of the above shortcomings, provide one kind well is not stayed to be anchored sand proof packing tool, Neng Gou
Anchoring sand control pipe is realized in work progress, improves construction safety reliability, it can be with Back-off Pipe String from well after construction
Out, it reduces the sand control later period and salvages difficult, saving operating cost.
The purpose of the present invention is what is be achieved through the following technical solutions:
The present invention includes: top connection, sealing ring, central upper portion pipe, floating piston, outer rotation set, lower central pipe, lock ring, lock ring
Set, lock nut, deblocking pin, torsion pass set, upper cone, slip sleeve, leaf spring, slip insert, lower contact；It is characterized by: described
Do not stay well anchoring sand proof packing tool for cylindrical shape, top connection is connected through a screw thread with central upper portion pipe, and central upper portion pipe is under
Portion's central tube is connected by left-hand thread, and spline arranged at central upper portion pipe lower part, and spline arranged at outward turning set top, in torsion pass set and lower part
Heart pipe is assembled together by spline and spline, and outer rotation set is connected through a screw thread with lock nut, and lock nut and torsion pass set pass through screw thread
Connection, lock ring set are linked together by unsealing pin with lower central pipe, the lower part of lower central pipe be successively arranged upper cone,
Lower cone, upper cone, lower cone peripheral hardware slip sleeve, slip sleeve are equipped with 6-8 block slip insert, and the lower thread of lower central pipe connects
Lower contact, lower contact by lower cone, slip sleeve limit.
Above-mentioned one kind is not stayed between the upper end and top connection of the central upper portion pipe in well anchoring sand proof packing tool, in top
Sealing ring together is equipped between the lower end inner wall and lower central pipe of heart pipe.
Above-mentioned one kind do not stay well anchoring sand proof packing tool in floating piston outer wall and top connection between, floating piston
Inner wall and central upper portion pipe between be equipped with two seals.
Above-mentioned one kind is not stayed the lower central pipe in well anchoring sand proof packing tool and is again provided with together between lower contact
Sealing ring is equipped with deblocking pin between the middle and upper part of lower central pipe and lock ring set.
It is annular shape that above-mentioned one kind, which does not stay the lock ring in well anchoring sand proof packing tool, and lower end is outer circle taper.
Above-mentioned one kind does not stay the lock nut in well anchoring sand proof packing tool to be similarly circular, and centre is equipped with a convex annular
Platform, upper end are equipped with " horn mouth ", and the taper of " horn mouth " is that outer cone taper is identical with lock ring lower end.
It is cylindrical shape that above-mentioned one kind, which does not stay the slip sleeve in well anchoring sand proof packing tool, is axially arranged with 6-8 around middle part
A oblong openings, opening size are slightly larger than slip insert size.
It is prismatoid that above-mentioned one kind, which does not stay the slip insert in well anchoring sand proof packing tool, and outside is equipped with serrated teeth.Seat
Card principle: oil pipe liquid feeding pressure, floating piston push outer rotation set, lock nut, torsion pass set, upper cone, slips under the action of hydraulic coupling
Tooth stretches out slip sleeve, is stuck on internal surface of sleeve pipe, meanwhile, lock ring covers uplink with outward turning；After pressure release, lock ring is locked at lock ring and puts on,
Prevent slip insert from bouncing back under the thrust of flat spring.
Unfreezing principle: rotating forward top connection, (top connection and central upper portion pipe are connected through a screw thread) central upper portion pipe and lower part
Central tube separation, above puts on connector certain distance, and the key of central upper portion pipe lower part enters in the keyway on outward turning set top, at this time may be used
Lock nut, torsion pass set and lock ring, lock ring is driven to cover uplink, when upper lifting force is greater than the shear strength of deblocking pin, lock ring set cuts solution
Offset nails on row, and upper cone is released at this time, and slip insert can be sprung back under the action of leaf spring, to realize unfreezing.
Torque transfer principle: after unfreezing, top connection is rotated forward, central upper portion pipe transfers torque to outward turning by key and keyway
Set, outer rotation set transmit torque to lock nut, torsion pass set by screw thread, and torsion pass set transfers torque to lower central by key and keyway
Pipe, lower central pipe transfer torque to lower contact by screw thread, to complete the positive torque transmitting of solid tool.
The beneficial effects of the present invention are: anchoring sand control pipe can be realized in the construction process, it is reliable to improve construction safety
Property, after construction can with Back-off Pipe String from well out, reduce the sand control later period and salvage difficult, reduce production cost, section
About operating cost increases crude output.
