发明名称 SYSTEM FOR CEMENTING TUBULARS COMPRISING A MUD MOTOR
摘要 A method and system for cementing a tubular and mud motor in a wellbore utilizing burst disks above the mud motor. The burst disks rupture to permit the cement to flow through the burst disks and bypass the mud motor. All of the burst disks reliably rupture at a predetermined and known threshold pressure so as to permit cement to be pumped at a desired rate through all of the ruptured burst disks. Each burst disk is provided with a cover for maintaining a chamber of a known pressure between the cap and the burst disk. All of the burst disks predictably and reliably rupture at the rated pressure.
