Definitions

  • This invention consists of an overvoltage fastening tool.
  • the inventor has considered that a tool that can prevent the sliding away of such components will minimize risks and has considered that this can be achieved by preventing the sliding or slipping away of the cable immediately after the equipment or the tool becomes detached.
  • the inventor has determined that since the cable is the nexus between the equipment or the tool lowered into the well and the reel, reel holder, and surface equipment, a development that permits stopping its movement will prevent damages at the surface.
  • the inventor has considered that the invention must permit the fall of the equipment or BES (ESP-Electric Submersible Pump) for its subsequent recovery.
  • BES ESP-Electric Submersible Pump
  • an overvoltage fastening tool that operates autonomously and automatically for safety purposes during the installation or extraction activities of tools and equipment in wells where piping and cables are present as is the case with oil and water wells, and the like. It is also a purpose of the invention to safeguard the integrity of personnel assigned to such activities. It is also a purpose of the invention to protect the equipment and tools that are being installed or extracted as well as those that may be affected by such operations. Another purpose of the invention is to permit easy recovery of the tools and equipment that have dropped to the bottom of the well as a result of the event.
  • the sensor activates in the event of an abnormal sliding or slipping of the cable when the latter is moving towards the bottom of the well.
  • the overvoltage fastening tool of the present invention includes three components: a first component to hold and fasten the cable of the tool or equipment; a second component having a sensor that activates the operation of the first component when any of the conditions take place for which it has been regulated; and, a third component that consists of a key that permits manual operation of the first component.
  • FIG. 1 is a diagram showing a cutaway view that permits viewing the cable fastening mechanism
  • FIG. 2 contains a diagram showing a view of an oil extraction tower, the reel, the reel holder, and the supply cable of an electric submersible pump;
  • FIG. 3 contains a diagram of the third component of the present invention that includes manual operating means
  • FIG. A 1 is another view of the container
  • FIG. A 2 is a further view of the container
  • FIG. B is a sensor
  • FIG. C is a manual operating means.
  • reference number 1 identifies an opening; 2 a handle; 3 a tube or line; 4 a clamp; 5 a fastening component; 6 a stop; 7 a cable; 8 an outside section; 9 an inside section; 10 an arm; 11 an intermediate piece; 12 a cam; 13 a stem; 14 a piston; 15 a cylinder; 16 a valve; 17 a high pressure hose; 18 an electric connector; 19 a button; and, 20 an elastic means.
  • letter “A” indicates a container; letter “B” indicates a sensor; and, letter “C” indicates a manual operating means or device.
  • the first one is a container A, which is made up of a quadrangular parallelepiped-shaped body; the second one includes a sensor B; and, the third is a manual operating means C.
  • the overvoltage fastening tool to be described has been designed to prevent damage caused by the retrieval or detachment of the electric submersible pumps when the supply cable is detached or cut, one thing is certain: it can be applied to any other equipment or tool that must be introduced or extracted from a well since the risks associated with the detachment or the breaking of the supply cable or the supporting cable are identical.
  • equipment designates a tool that requires a power cable, such as for instance an electric submersible pump.
  • the first of the components included in the overvoltage fastening tool is the container A for which dimensions vary on the basis of the requirements to which it may be subjected.
  • the material of such container A is any suitable material such as for instance corrosion resistant metal and arranged in the mouth or intake of an oil well.
  • an orifice of an appropriate size is provided at the bottom base of the container A to permit the entry and centering of the production line and of the bottom equipment.
  • an opening 1 is provided occluded with a removable blind cover in the event of enabling the outflow of oil such as for instance in the event of moving the well.
  • a handle 2 is provided at each side of the opening 1 so that both components make it possible to secure the container A to the BOP (blow-out preventer) valve.
  • BOP blow-out preventer
  • an orifice is provided in the upper base of the container A with an adequate size to permit access to the production line as well as to an equipment to be installed or removed.
  • a line 3 is provided that has an upper section where a clamp 4 is located and a lower section where a cutoff component 5 is provided. It is facing a stop 6 against which it makes contact when the sensor B signal is triggered or it activates against the manual operating medium C.
  • the clamp 4 is located on the internal surface of line 3 and the free space of the latter can be arranged to hold or release the cable 7 which links the equipment to a supply source.
  • reference 7 indicates a cable, the term also covers interchangeably a hose so that the reference alludes to any of them.
  • the latter consists of an outside section 8 and an internal section 9 where the external section 8 is fixed while the internal section 9 is attached to an arm 10 for which the lower end has a point of articulation with an intermediate part 11 linked to a cam 12 activated by the stem 13 and a piston 14 .
  • the piston 14 When as a result of the incoming fluid, the piston 14 is displaced inside the cylinder 15 , it pushes the end of the cam 12 to which it is connected downward, and provides an ascending movement to the other end of the cam. As a result of the special shape of the cam 12 , the rise of the end pushes the arm 10 and moves it in the direction of the external section 8 of the tube 3 , thus permitting the clamp 4 to close against the cable 7 and holding it.
  • the stem 13 is pushed to leave the cylinder 15 , thus displacing the cam 12 as a result of the inflow of fluid coming from a valve 16 connected to a high pressure hose 17 linked to a deposit.
  • the sensor B detects a displacement of the cable 7 , it acts through a signal of an electric connector 18 that sends the fluid from the deposit and through the high pressure hose 17 and the valve 16 towards the cylinder 15 pushing the piston 14 .
  • the third component of the invention is a manual operating means C that includes a button 19 that as soon as it is pressed, activates the electric connector 18 which like in the case of an automatic trip, pushes the fluid from the deposit to the cylinder 15 .
  • the electric connector 18 is closed (deactivated), the fluid flow toward the cylinder 15 ceases.
  • the elastic means 20 located between the arm 10 and the internal section 9 expands and pushes the arm 10 towards the at-rest position, pulling with it the securing element 5 and the cam 12 .
  • the fluid to which reference is made can be of any type; with it, one can adapt the invention to the particular conditions of each specific case. As such, it can be hydraulic, electric or gaseous fluid.
  • a removable blind cover is located that permits access to the inside.
  • It includes a quadrangular and parallelepiped-shaped container A; a sensor B, and a manual operating means C.
  • the container A has an access orifice at its lower base that permits the entry and centering of the production tube and bottom equipment; an opening 1 occluded with an extractable blind cover at one of its sides; an access orifice at its upper base that permits the entry to the production tube as well as to an equipment to be installed or to be removed and a removable blind cover that permits access to its inside from the back.
  • a tube 3 is provided that has an upper section where a clamp 4 is located and a lower section that provides a cutoff 5 component that faces a stop 6 against which contact is made when the sensor B signal is tripped or it acts against the manual operating means C.
  • the clamp 4 is located in the internal surface of the tube 3 for which the free space can be arranged to secure or release the cable 7 that links the equipment with a supply source.
  • the tube 3 has a fixed external section 8 and an internal section 9 connected to an arm 10 where, at its lower end, it forms a point of articulation with an intermediate part 11 connected to a cam 12 operated by the stem 13 of a displaceable piston 14 within a cylinder 15 as soon as a fluid is entering that pushes an end of the cam 12 downward and elevates the other that pushes the arm 10 in the direction of the external section 8 of the line 3 that closes the clamp 4 against the cable 7 .
  • the manual operating means C includes a button 19 that activates the electric connector 18 that pushes the fluid from the deposit to the cylinder 15 and once the emergency has ended, the electric connector 18 closes or deactivates and ceases the fluid flow in the direction of the cylinder 15 so that the elastic means 20 arranged between the arm 10 and the internal section 9 expand and pushes the arm 10 towards the at-rest position that displaces the internal section 9 and opens the clamp 4 , releasing the cable 7 and pulling the cutoff component 5 and the cam 12 that drives the stem 13 upward pushing the flow through the valve 16 and the high pressure hose 17 towards the deposit.
