Description

Introduction

Heavy weight drill pipe is the transition drilling string section between common drill pipe and drill collar, it can effectively alleviate the stress concentration of the transition section in the combination of the drill pipe and the drill collar, provide drilling pressure and also can effectively reduce the connection area between the drill string and the wall of the well and decrease the outside diameter wear rate. The central part of the heavy weight drill pipe is thickened, and the surface of the joint and the thickening part is welded with cemented carbide to form hard band, so that wear and tear of the drill pipe can be effectively protected. AISI 4145H structural alloy steel is selected as the material for heavy weight drill pipe.
