Abstract

The present invention relates to a stabilizing system adapted to be used in a deep drilling system. The stabilizing system comprises a longitudinal housing and a spring, preferably a helical spring, arranged inside the housing. Thereby, the stabilizing system is contracted and the spring is compressed along the longitudinal axis of the stabilizing system when an external load is applied in longitudinal direction onto the stabilizing system. The transversal diameter of the stabilizing system increases when the stabilizing system is contracted. Further, the transversal diameter of the stabilizing system decreases when the stabilizing system expands along the longitudinal axis.

Description

RELATED APPLICATION DATA[0001]This application is a continuation of U.S. patent application Ser. No. 17 / 252,078, filed Dec. 14, 2020, which is a national phase of International Patent Application No. PCT / IB2018 / 054235, filed Jun. 12, 2018, each of which is incorporated herein by reference.FIELD OF THE INVENTION[0002]The present invention relates to a deep drilling system, and in particular to a stabilizing system to be used in such a deep drilling system, and a method for drilling a hole utilizing such a deep drilling system.TECHNICAL BACKGROUND[0003]In a deep drilling system, a drill bit is typically connected via several drill pipes, forming a drill string, to a drilling motor. Such a setup is also generally illustrated in FIG. 1. The drilling motor, provided on the earth's surface, applies drilling forces (the longitudinal and rotational forces as illustrated by arrows in FIG. 1) onto the drill string 1 such that the drill bit 3 advances further into the ground 4, thereby creatin...
