Problems solved by technology

However, US4042123 does not teach any step of picking up the drill rod by the drill bit, also known as "top drive"
[0007] In the event of an explosion or uncontrolled release of fluid and gas (also known as "blowout"), there is a real risk that the outflow of fluid and gas from the last rod at the top of the well may not be controlled

Embodiment Construction

[0018] refer to figure 1 , 2 , reference numeral 10 generally designates a device for automatically handling drill pipe and tubular wellbore casing elements.

[0019] The automated handling method that will be described below consists of two main sub-methods:

[0020] - a first sub-method: picking up drill pipe from a drill pipe container for placing drill pipe into the main well; and

[0021] - Second sub-method: picking up drill pipe from the main well for placing the drill pipe into the container.

[0022] The method described below is automatically carried out by a drilling rig 10 having a movable drill head 20 (top drive) movable from a main well 100 to a secondary well 200 in which drill pipes 30 are temporarily stored.

[0023] Likewise, the movable drill bit 20 may include a tool capable of removably constraining itself to the tubular wellbore housing element 30a, the tool being driven into and covering the wellbore 300, thereby coupling the drill pipe 30 with the ...

Abstract

A method for automatic handling of drilling rods, comprising a step of handling at least one drilling rod (30) by means of a handler (40) designed for simultaneously clamping and moving the drilling rod (30), and wherein the handler (40) moves the drilling rod (30) from an auxiliary retaining means (200) to a main well (100); said method is characterized in that said handling step takes place automatically and is controlled by a data processing unit, and that the method comprises an automatic handling of a drill head (20) fitted with a chuck susceptible to being screwed to said drilling rod (30); the automatic handling occurring among a plurality of heights (ql-q6) stored in the data processing unit.

Description

technical field [0001] The present invention relates to methods for handling drill pipe and tubular wellbore casing elements; more particularly, the present invention relates to methods for automatically handling drill pipe and tubular wellbore casing elements, excavating equipment therefor and associated computer programs . Background technique [0002] It is known that conventional drilling rigs use drill pipes which are driven in series one after the other into the main well. [0003] It is also known that conventional drilling rigs are fitted with a drill bit above the main well, the side of which meets the service well, this is known in the art as a rat hole, after it has been picked up from the drill pipe container by the rod handler, Drill pipe is temporarily stored waiting to be picked up by the rig's bit, and the rod just picked up from the rat hole is then translated again above the main well. [0004] Traditionally, the process of picking rods from the service h...
