    • A multi-functional apparatus and method for drilling fluid and cementing operations to set casing in a wellbore for use on either top drive or rotary type rigs. The apparatus and method includes a fill-up and circulating tool, a cementing head assembly, a wiper plug assembly, and a push plate assembly. The fill-up and circulating tool comprises a mandrel with a sealing element disposed about the outside diameter of the mandrel. The cementing head, push plate, and wiper plug assemblies are useable on any fill-up and circulating tool capable of being inserted into a casing. To fill the casing, the assembly is lowered from the rig such that a portion of the fill-up tools inserted into the casing, the pumps are then actuated to flow fluid into the casing. To circulate fluid, the tool is lowered further such that the sealing element sealingly engages the inside diameter of the casing to allow fluid to flow through the casing, into the wellbore, and back to the fluid pumps. To utilize the push plate assembly, the push plate is rotated until attachment pins engage into corresponding J-slots and lock the plate in place. The fill-up tool is lowered so that the push plate contacts the top of the casing thus transferring the rig load onto the casing. To cement the casing, the cement pump and hose assembly is connected to the cementing head to allow cement to be pumped through the fill-up and circulating tool and into the casing string. A cement plug assembly comprising a plurality of wiper plugs is connected to the outlet of the fill-up and circulating tool. The wiper plugs are then released at a predetermined time during the cementing process to provide a positive seal at the bottom of the casing string.
    • 一种用于钻井液和固井作业的多功能装置和方法,用于将套管设置在井筒中以用于顶部驱动装置或旋转式钻机上。 该装置和方法包括填充和循环工具,固井头组件,雨刷插头组件和推板组件。 填充和循环工具包括具有围绕心轴的外径设置的密封元件的心轴。 固定头,推板和雨刷插头组件可用于能够插入壳体的任何填充和循环工具。 为了填充壳体,组件从钻机中降低,使得填充工具的一部分插入壳体中,然后泵致动以将流体流入壳体。 为了循环流体,工具进一步降低,使得密封元件密封地接合壳体的内径,以允许流体流过套管进入井筒,并返回流体泵。 为了利用推板组件,推板旋转直到连接销接合到相应的J形槽中并将板锁定在适当的位置。 填充工具下降,使得推板接触壳体的顶部,从而将钻机负载传送到壳体上。 为了胶合套管,水泥泵和软管组件连接到固井头,以允许水泥被泵送通过填充和循环工具并进入套管柱。 包括多个雨刷的水泥塞组件连接到补充和循环工具的出口。 然后在固井过程中在预定时间释放雨刷塞,以在套管柱的底部提供正密封。
