摘要： A spring for use in downhole tools delivers a high force over a long deflection in a relatively uniform fashion. The spring is a tubular shape that is preferably metallic and is preferably plastically deformed into an undulating walled tube either before assembly into a downhole tool or downhole after assembly to the downhole tool. Alternatively the shape can be machined. Spacer rings are used inside and outside the tube as it is compressed to obtain the desired corrugated wall pattern and to prevent localized buckling that can cause wall failure. The spring can conduct pressurized fluids and be rotationally locked to transmit torque and to facilitate milling out. Some machining internally and/or externally can assist in forming the desired corrugated wall shape.

摘要： The removable plug features a solid material that is housed in a porous container that has its shape changed to transition from the run in shape to the set shape. A swage is moved through a passage in the container to enlarge the passage and move the container to a borehole wall. The passage is then closed such as with a flapper valve or by moving in a mandrel into the expanded passage and lodging the mandrel in the expanded passage. Various release techniques are described.

摘要： The removable plug features a solid material that is housed in a porous container that has its shape changed to transition from the run in shape to the set shape. A running string and setting tool that creates relative movement deliver the plug and pull on its lower end while holding the top stationary against a backing plate. The container is pulled into itself as the radial dimension grows for the set. There can be a mandrel that remains in position and can lock to the backing plate or alternatively there can be no mandrel or a removable mandrel. The porous container can be removed in a variety of ways to let the solid material escape to be removed with fluid circulating in the wellbore. Alternatively the mandrel can be undermined to let the solid material escape for recovery.

摘要： A seal is retrofit to an existing seal groove and made whole after being positioned in the groove. It can be an initial coil shape to allow it to slip over a shaft to get to the groove or it can be in a plurality of sections that are joined in place. The sections can be abutting or overlapping and are preferably coated with a brazing material that will ultimately join such ends. The ends can then have a nano-engineered coating that comprises alternating layers of aluminum and nickel that when initiated with applied heat becomes reactive exothermically to join the ends using the brazing material.

摘要： A downhole wet connect uses a bearing relation between materials to take advantage of the piezoelectric effect between them. Voltage is applied from the surface to the uphole pad which induces a voltage to be generated from the downhole pad to a storage device to store power for operating downhole equipment. The generated voltage can also be used as a real time power supply for downhole equipment. Alternatively, the generated voltage can be coded as a signal to downhole equipment to send date acquired downhole to the surface. The transmission of information is two way. Voltage input from the surface is stopped as downhole equipment sends a voltage based signal uphole for conversion by surface processors to capture the data. Alignment or downhole debris issues do not affect the transmission capability of the pads in the wet connect.

摘要： A vibratory tool for use in a tubular string to prevent sticking or to release a stuck string features a fluid operated dart valve working in conjunction with an impact sleeve to deliver continuous axial jarring blows in opposed directions as long as flow is maintained. Movement of one of those components axially in opposed directions opens and closes access to opposed lateral ports so that a lateral vibration is also established as flow cyclically occurs and stops sequentially at opposed lateral outlets.
