Problems solved by technology
From the context of string construction as a dynamic activity, situations can easily arise that define how the string will be operated because, for example, another type of drill bit than the one assumed in the control program is installed in the drill string Instructions are inconsistent with the control parameters defined by component suppliers for individual components in the string

Embodiment Construction
[0025] In the drawings, reference numeral 1 denotes a drilling rig, in which a derrick 12 protrudes from a drilling platform 11 . Drilling rig 1 is equipped with various drilling operation equipment, here is shown the means for rotating the pipe string 2, typically the rotary table 132 and the drilling machine 131 (which also represents the Axially displaced equipment), a circulation system 133 for drilling fluid, etc., and a manipulator or robot for manipulating tubular components, etc. in association with operations on the drilling platform 11.
[0026] A tubular string 2 extends through the rotary table of the drilling platform 11 and down into a borehole (not shown), the tubular string 2 being made up of various tubular string components, shown here with reference numerals 21, 21a, 21b, 21c, 21d, 21e and 21f. A string part 21 g waiting to be connected to the string 2 is also shown at a position directly above the string 2 . Another column part 21 n is placed in the first...

A system is described for constructing control commands for a tool assembly formed as a pipe string (2) at least partially arranged to be inserted into a borehole, in which pipe string parts (21, 21n) is provided with a unique machine-readable identification carrier (211, 211a, 211b, 211n) capable of being identified by the controller (42) via one or more readers (422, 422', 422") , the controller (42) is connected to a database (41) containing a component data set (411) for each string component (21, 21n), the controller (42) is arranged to After the column components (21, 21n) have been recorded by the readers (422, 422', 422"), the corresponding component data set (411) is included in the control instruction set (421), so that at any time according to the The relevant components of (2) generate control instructions for the associated drilling operation equipment (131, 132, 133, 134, 134'). Also described is a method of constructing control commands for a tool assembly formed as a tubular string (2) at least partially arranged to be inserted into a borehole.
Description
technical field [0001] The present invention relates to a system and method for constructing control commands for a tool assembly formed as a tubular string arranged for insertion into a borehole, wherein the tubular string components are provided with a unique machine-readable identification carrier capable of being read by a controller via One or more readers to identify. Background technique [0002] When tool strings are used in drilling etc., e.g. for hydrocarbon exploration and production, it is necessary to have complete knowledge of which components are present in the tool string, and where important components are located in the borehole, such as which type of drill string is equipped with the drill bit, and how deep the drill bit has moved in the borehole, to ensure correct operation of the tool, such as stopping the drill string before the bit hits the end of the hole, and said drill head is set to rotate at a high speed rotate. In order to know where the drill ...
