[0176] The lubricating substance included three chemical EP additives, sulfur-containing products, overbased sulfonates, and metal dithiophosphates, all of which were oil-soluble components. Waxes are also soluble in oils.
[0185] It should be noted that oxidized petrolatum wax is a very temperature-stable compound that does not deteriorate chemically when the temperature is maintained at 160°C. This chemical stability allows the threaded connection to be lowered to the bottom of a well, where temperatures can reach 160°C, without irreversibly changing the properties of the wax; the threaded connection can then be lifted out of the well, disassembled before reassembly, and Descend again into the same well or another well.

Abstract
The invention relates to the threaded part of a galling-resistant threaded connection, wherein a thin film of a lubricating substance is deposited on at least the surface of the thread of the threaded connection, said surface being treated to absorb said lubricating substance. The lubricating substance is a homogeneous mixture consisting of: a) a thickener; b) a set of extreme pressure additives whose physical and chemical properties are compatible with the thickener and which include at least Functional extreme pressure additive, which can be used under Hertz pressure not lower than 1000MPa; c) Oil. The proportions of the lubricating substance components are chosen such that the consistency of the lubricating substance ensures self-discharging of the lubricating substance and film formation. The invention also relates to methods of forming the film.
Description
technical field [0001] Field of the Invention This invention relates to male or female threaded elements at the ends of pipes which can be joined together to form galling resistant threaded pipe connections. More specifically, it relates to threaded pipe connections that do not require hand grease during assembly. Background technique [0002] Such threaded members and threaded pipe connections are particularly suitable for forming casing or production or drillpipe banks for hydrocarbon wells and the like, such as geothermal wells. [0003] Tubes of this type are generally formed vertically, and the faces of the free ends of the rows of tubes include female threaded members with internal female threads. [0004] In order to lower the pipe row into the well, new pipe is placed on top of the pipe row with a male threaded member comprising an external male thread compatible with the female thread on the corresponding free end of the pipe row, the male thread of the new pipe b...
