Abstract

A pressure pulse generator for use in MWD operations in a drilling installation having a drillstring, a drilling bit, means for supply drilling fluid via the interior of the drillstring to the drilling bit, and an annulus between the drillstring and the wall of the bore hole being formed. The pressure generator generates a pressure pulse signal in the drilling fluid which transmits such signal to pressure monitoring equipment at the surface. The pressure pulse generator includes an outer housing which can be mounted in a drillstring component, and in which the operating components of the pulse generator are housed; a main valve having a valve operating chamber which allows drilling fluid to pass from the interior of the drillstring to the exterior when the valve is opened, and thereby to generator a pressure pulse signal that travels to the surface. A first pilot valve allows fluid in the operating chamber of the main valve to communicate with the drilling fluid in the annulus, and a second pilot valve controls flow of drilling fluid between the inside of the drillstring and the operating chamber of the main valve.
