Description

Expanding open hole packer
Technical field
The present invention is the packer of using at the bottom of the permanent plugged well in oil field, is a kind of expanding open hole packer.
Background technology
The inflatable packer that oil-field flooding is used is that packing element expands outwardly when the packing element internal pressure is higher than the packing element external pressure, realization sealing oil casing annular space.Will deblocking when present inflatable packer does not have pressure in inside, be not suitable for the requirement at the bottom of the permanent plugged well in oil field, the inflatable packer that has is provided with unidirectional mechanism in inside, deblocking not in the time of can guaranteeing not have pressure reduction within a certain period of time, but keep the not limited time of deblocking, also be not suitable for the requirement at the bottom of the permanent plugged well in oil field.
Summary of the invention
The purpose of this invention is to provide a kind of expanding open hole packer, be applicable to the requirement at the bottom of the permanent plugged well in oil field.
The object of the present invention is achieved like this: by top connection, last packing element sheath, gluing socket joint head, interior pipe, outer packing element, the rubber that rises of splashing, the lower rubber cylinder sheath, the lower rubber cylinder joint, sealing shroud, inner pipe joint, one way valve, upper piston, lock ring, cylinder body, lower piston, connect pin, lower contact, cutting off pin forms, top connection is connected with interior pipe top, gluing socket joint head, outer packing element, the lower rubber cylinder joint is sulfided into one, last packing element sheath is connected with gluing socket joint head, last packing element sheath covers outer packing element top, the lower rubber cylinder sheath is connected with the lower rubber cylinder joint, the lower rubber cylinder sheath covers outer packing element bottom, the rubber that rises of splashing is packed in the outer packing element, last packing element sheath, gluing socket joint head, outer packing element, the rubber that rises of splashing, the lower rubber cylinder sheath, the lower rubber cylinder joint is sleeved on outside the interior pipe after being assembled into one, inner pipe joint top is connected with interior pipe bottom, the inner pipe joint bottom is connected with lower contact, sealing shroud is sleeved on outside the lower rubber cylinder sheath bottom, the sealing shroud bottom is connected with cylinder body top, cylinder body is sleeved on inner pipe joint, outside the lower contact, cylinder body is fixed in the lower contact by connecting pin, install piston between cylinder body and the inner pipe joint, lower piston, lower piston lower end area is greater than the upper end area, one way valve is installed in the cylinder body upper end, lower piston is fixed on the inner pipe joint by cutting off pin, last linked hole and following linked hole are arranged on the inner pipe joint, lower piston is on the following linked hole, upper piston is under the linked hole, the upper piston outer wall is installed lock ring, the lock ring groove is arranged on the cylinder body, the lock ring groove is on the lock ring, and the lock ring groove can cooperate with lock ring.
The invention has the beneficial effects as follows: the rubber that rises of splashing is met to splash behind the water and is risen, and makes outer packing element expansion seal the shaft bottom of barefoot completion, and one way valve and lock ring make outer packing element forever be in expansion state, and therefore, the present invention is applicable to the requirement at the bottom of the permanent plugged well of oil field open hole well.
Description of drawings
Accompanying drawing 1 is a structure assembling drawing of the present invention.
The specific embodiment
Describe below in conjunction with 1 pair of embodiments of the invention of accompanying drawing.
As shown in the figure, embodiments of the invention are by top connection 1, last packing element sheath 2, gluing socket joint head 3, interior pipe 4, outer packing element 5, the rubber 6 that rises of splashing, lower rubber cylinder sheath 7, lower rubber cylinder joint 8, sealing shroud 9, inner pipe joint 10, one way valve 11, upper piston 12, lock ring 13, cylinder body 14, lower piston 15, connect pin 16, lower contact 17, cutting off pin 18 forms, top connection 1 is connected with interior pipe 4 tops, gluing socket joint head 3, outer packing element 5, lower rubber cylinder joint 8 is sulfided into one, last packing element sheath 2 is connected with gluing socket joint head 3, last packing element sheath 2 covers outer packing element 5 tops, lower rubber cylinder sheath 7 is connected with lower rubber cylinder joint 8, lower rubber cylinder sheath 7 covers outer packing element 5 bottoms, the rubber 6 that rises of splashing is packed in the outer packing element 5, last packing element sheath 2, gluing socket joint head 3, outer packing element 5, the rubber 6 that rises of splashing, lower rubber cylinder sheath 7, lower rubber cylinder joint 8 is sleeved on outside the interior pipe 4 after being assembled into one, inner pipe joint 10 tops are connected with interior pipe 4 bottoms, inner pipe joint 10 bottoms are connected with lower contact 17, sealing shroud 9 is sleeved on outside lower rubber cylinder sheath 7 bottoms, sealing shroud 9 bottoms are connected with cylinder body 14 tops, cylinder body 14 is sleeved on inner pipe joint 10, outside the lower contact 17, cylinder body 14 is fixed in the lower contact 17 by connecting pin 16, install piston 12 between cylinder body 14 and the inner pipe joint 10, lower piston 15, lower piston 15 lower end areas are greater than the upper end area, one way valve 11 is installed in cylinder body 14 upper ends, lower piston 15 is fixed on the inner pipe joint 10 by cutting off pin 18, last linked hole 20 and following linked hole 21 are arranged on the inner pipe joint 10, lower piston 15 is on the following linked hole 21, upper piston 12 is under the linked hole 20, upper piston 12 outer walls are installed lock ring 13, lock ring groove 19 is arranged on the cylinder body 14, lock ring groove 19 is on the lock ring 13, and lock ring groove 19 can cooperate with lock ring 13.
