  • This development basically consists of an Hydraulic Packer constructed in glass-fiber reinforced epoxy and stainless steel.
  • Hydraulic Packer It is a tool used in production or injection wells, called Hydraulic Packer and it is used to isolate oil, gas or water layers.
  • this tool has a hydraulic piston system that slides down inside a hydraulic chamber.
  • the tool is driven to one of the ends, thus achieving the anchorage and the packing of elements.
  • the hydraulic sleeve and piston have a jack system which makes the tool not to go back when giving pressure and to support its anchorage and packing with a certain strength, which is given by the areas of the piston, the mandrel and the hydraulic sleeve.
  • this tool is a cylindrical hybrid, it is machined with conventional machines, such as industrial lathes and industrial milling cutters. All of the parts of this tool go through a turning and milling process, including the stainless steel and the glass-fiber reinforced epoxy parts.
  • the raw material is in the manner of cylindrical bars, which are machined with machine tools such as lathes and milling cutters.
  • the machining of the glass-fiber reinforced epoxy parts is carried out in a conventional manner, by only changing the turning advancing and the chip removal, since it is a material more brittle than steel.
  • the operative innovation that this tool has is a larger area of packing and seal, due to its system of strong packing elements, specially adapted for this tool. It works with low pressure of operation, which reduces accident risks.
  • Its hydraulic chamber was specially designed to achieve a larger strength of packing at normal pressure, and it enables its use in wells with glass-fiber reinforced epoxy tubing, without the need to do the double fixing stroke with steel tubing of conventional tools.
  • Hydraulic Packer constructed in glass-fiber reinforced epoxy and stainless steel it is hydraulically operated by means of pressure applied from the surface of the well.
  • Such liquid goes through the entrance hole (a) from the mandrel ( 1 ) and moves the piston holder ( 2 ), the element holder sleeve ( 3 ) and the upper cone ( 4 ).
  • This one due to its conical shape in its lower end moves the jaw ( 5 ) outwards until it hits the casing (not represented).
  • the piston holder ( 2 ) and the element holder sleeve ( 3 ) go on advancing, compressing the packing elements ( 6 ) and the lower cone ( 7 ) joined to the mandrel.
  • the mandrel ( 1 ) is wholly made of glass-fiber reinforced epoxy, while the piston holder ( 2 ), the element holder sleeve ( 3 ), the upper cone ( 4 ), the jaw ( 5 ) and the lower cone ( 7 ) are made of steel SAE 4140 N with nickel-plating superficial treatment.
  • the packing elements ( 6 ) are made of acrylonitrile.
  • This model represents a set with pistons ( 8 ) prepared to operate in wells where there are differential pressures; that is to say, this packer is prepared to be anchored to the pipe with the jaws ( 5 ) and the pistons ( 8 ).
  • the pistons ( 8 ) are operated by means of the ground pressure of the fluid that enters through the admission holes (b) of the upper cone ( 4 ), goes along the mandrel ( 1 ), the element holder sleeve ( 3 ) and then gets below the pistons ( 8 ). In this way the fluid pressure moves them outwards and anchors them in the casing (not represented).
  • the pistons ( 8 ) are only activated when we have a well with ground pressure, to help this pressure not to move the packer and so have an effective grip of the tool through the jaws ( 5 ) at the lower part and of the pistons ( 8 ) at the upper part. It can be observed that the pistons ( 6 ) hit in the piston strip ( 19 ).
  • the fixing mandrel ( 9 ) When operating the tool in its upper part, the fixing mandrel ( 9 ) is joined to the mandrel ( 1 ) and the pieces that slide down to the lower end of the packer are the pin holder nut that goes screwed to the hydraulic sleeve ( 11 ) that at the same time is joined with the piston holder ( 2 ) and the rest of the pieces as it has already been explained. They slide through the movement that the restraint ring ( 12 ) does which is inside the pin holder nut ( 10 ) and that works like a jack, at the same time the pressure pushes the hydraulic sleeve ( 1 ) with the piston holder ( 2 ) and the rest of the pieces. The restraint ring ( 12 ) is advancing and restraining at the same time, it is fixing in the saw thread of the fixing mandrel ( 9 ) since the restraint ring ( 12 ) has the same thread but counterclockwise.
  • the restraint ring ( 12 ) supports all the packing and fixing of the jaws in the fixing mandrel ( 9 ) since it remains embedded in the saw tooth threads.
  • the pistons ( 8 ) are made of steel SAE 8620 with nickel-plating surface treatment
  • the fixing mandrel ( 9 ) can be made of steel SAE 4140 N with nickel-plating surface treatment or of stainless steel AISI 316L
  • the pin holder nut ( 10 ) are made of steel SAE 4140 N with nickel-plating surface treatment.
  • the hydraulic sleeve ( 11 ) can be made of glass-fiber reinforced epoxy or stainless steel AISI 316L.
  • These can be obtained either in steel SAE 4140 N with nickel-plating superficial treatment or in glass-fiber reinforced epoxy.
  • jaws ( 5 ) and the lower cone ( 7 ) are placed into the jaw holder ( 16 ) which can be either made of steel SAE 4140N with nickel-plating surface treatment or of glass-fiber reinforced epoxy.
  • the mandrel ( 1 ) is connected to the rest of the components of the oil well by the upper header ( 17 ), placed in the first end of the packer and by the lower header ( 18 ) placed in the opposite end, both made of glass-fiber reinforced epoxy or of stainless steel AISI 316L.
