摘要： A method of reducing contact pressure between bearing surfaces of a well tool can include constructing a structure which supports one bearing surface in contact with the other bearing surface, and reducing contact pressure between the bearing surfaces by relieving strain energy in the structure. A well tool can include one bearing surface which contacts another bearing surface. There is a transition between contact and lack of contact between the bearing surfaces. A structure supporting one of the bearing surfaces can have a reduced stiffness, whereby a contact pressure between the bearing surfaces is reduced at the transition. The bearing surfaces can be formed on a thrust bearing, plain bearing, or other type of bearing between components of the well tool.

摘要： A swellable packer can include a material which swells when contacted with a swelling fluid, and a barrier comprising a highly crystalline polymer which is substantially impermeable to the swelling fluid. A method of controlling swelling of a material can include positioning the material and a barrier in a well, the barrier preventing contact between the material and a swelling fluid, the barrier comprising a polymer, and increasing a permeability of the barrier to the swelling fluid in response to the barrier polymer being heated to its crystallization temperature. A well system can include a material which swells in response to contact with a hydrocarbon gas, and a barrier which comprises a crystalline polymer, the polymer being substantially impermeable to the hydrocarbon gas, whereby the polymer initially prevents swelling of the material, but the polymer becomes increasingly permeable to the hydrocarbon gas when heated to its crystallization temperature.

摘要： Selective placement of conformance treatments in multi-zone well completions. A method includes injecting a relative permeability modifier into a zone and optimizing a ratio of desired fluid to undesired fluid produced from the zone, including adjusting at least one flow control device between fully open and fully closed configurations. Another method includes injecting a relative permeability modifier into multiple zones, one at a time, via respective flow control devices, and then producing fluid from each of the zones. Another method includes identifying which of the zones to treat by, for each of the zones: a) closing flow control devices corresponding to the other zones, and b) evaluating fluid produced from the zone; and injecting a conformance treatment into the zones identified as the zones to treat.

摘要： A control system for an annulus balanced subsurface safety valve. A system for operating a safety valve in a well includes a piston of the safety valve being responsive to displace due to a pressure differential between chambers exposed to the piston; and a valve controller which alternately exposes at least one of the chambers to pressure in an annulus surrounding the safety valve, and to pressure greater than that in the annulus. A method of operating a safety valve in a well includes the steps of: opening the safety valve by biasing a piston of the safety valve to displace in response to a pressure differential between a chamber exposed to pressure greater than well pressure, and another chamber exposed to well pressure; and closing the safety valve by exposing both of the chambers to the well pressure.
