DE2233569C3 - A method of making a lubricant for lubricating the outer surface of a string of drilling tubing - Google Patents

Description

According to this process, the components contained in the mixture are only applied to the

The invention relates to a method for the production of the melting temperature, which is used for the penetration of lubricants to lubricate the outer shear and to achieve a homogeneous mass surface of a drill pipe column. This lubricant is required. At this temperature, when drilling boreholes by means of sealing components, the core and hard metal-tipped drill bits do not undergo any chemical reactions with one another; therefore, the mechani-uses obtained show the use of water as the rinsing liquid. Mixtures do not see sufficient resistance It is well known that at high rotational speeds a strong vibration occurs relatively quickly from the strength of the drill pipe column, the surface of the drill pipe
It is the aim of the present invention to transfer the drilling machine and therefore to eliminate the difficulties mentioned,
faster wear leads to the Bohningsgeschwin- The invention is based on the object

durance and the consumption of diamond 45 Process for the production of a lubricant for and carbide increases. Lubricating the outer surface of a tubular column under vibration conditions It takes the effort to develop power for turning, which leads to a lubricant that the drilling column in the borehole very strongly (sometimes adheres better to the surface of the drill pipe and by 2 to 2.5 times), while the core output is therefore less able to be played out and the opposite is less is reduced. 50 known processes produced lubricants economically

As a result, vibration control is more economical.

It is also included in the method according to the invention. Nigrols are advantageous in the reaction vessel if the components for the mixture intended for the preparation of the lubricant (75 percent by weight), paraffin (10 percent by weight) are introduced with fol and hard pitch (15 percent by weight). The proportions by weight are as follows: Nigrol 55 to the contents of the vessel is heated to 100 ° C. and carefully mixed with 75 V ·, paraffin 5 to 10 · / ·, practically no soda and for 15 to 20 minutes; then the resin pitch, which does not contain any alkali, is rapidly increased to between 15 and 35 ° C and temperature to 260 to 270 ° C. The rest of the bitumen. The listed component ratio is maintained at this temperature of 270 ° C and the mixture is kept at 30 min. Now the finished lubricant is poured onto a material of higher quality, which is cooled from the top of the pipe to 80 to 90 ° C and flattened in packaging while drilling for a long time,
