Abstract
A fluid sampling apparatus, adapted for its descent into a well by means of a cable, comprising an elongated support, a first seal in said support cooperating with the wall and surrounding the opening of a sample receiving conduit initially closed, in connection with a sample chamber, a device in said support, actuated by a hydraulic pressure system to move said leakproof closure until it is brought into cooperative contact with the well wall, an explosion perforator through said opening to opening said conduit to the fluid coming from the part of the wall insulated by sealing, a transducer responsive to pressure variations at a point along said conduit to obtain pressure measurements; said apparatus characterized in that a first valve is provided to close said conduit beyond said pressure measurement point for a chosen time after detonation of said perforator.
