Abstract

A test drill string for testing underground deposits of pumpable media found by boring a deep well comprises a test section (6) in the area of its bottom end, with measuring instruments, packing (4) for sealing the annular space above a perforated area (7) of the test section (6), and a delivery pump, in particular a Moineau pump, consisting of stator (8) and rotor (12). In this arrangement, the rotor (12) of the delivery pump, when delivery is required, can be lowered by means of a separate drive linkage (13) from the head of the bore hole (1) into the test drill string (T) down into an operating position and can be set in rotation in the operating position inside the stator (8) by means of a drive motor (M) on the surface. <IMAGE>
