Abstract

本实用新型公开了一种新型液压吊卡,包括吊卡主体,吊卡主体的通孔内镶嵌有套筒。本实用新型结构合理,操作方便,工作性能好;不需要将吊卡从吊环上摘下就能进行吊卡规格、品种的更换,以减少钻井作业时所需吊卡的规格、品种,减低钻井成本,方便油田工人操作,便于管理。

Description

新型液压吊卡
技术领域:
本实用新型涉及一种石油天然气钻修井作业中用于卡持、提升管柱的吊卡。
背景技术:
现有提升管柱的吊卡均为根据管柱的规格而加工相对应的孔径,由于在石油天然气钻修井作业中管柱的种类多,有钻杆、钻铤、套管、油管等,各类管柱的规格也特别多,所以钻井作业时,需要配备的各类、各种规格的吊卡十分多,并且钻井作业时,更换管柱规格、品种时,就得将吊卡从吊环上摘下进行更换,既增加了钻井作业的难度、浪费了时间,又增加了钻井成本和管理难度。
发明内容:
本实用新型的目的在于提供一种结构合理,操作方便,工作性能好的新型液压吊卡。
本实用新型的技术解决方案是:
一种新型液压吊卡,其特征是:包括吊卡主体,吊卡主体的通孔内镶嵌有套筒。
套筒为剖分式或多片式。
本实用新型结构合理,操作方便,工作性能好;不需要将吊卡从吊环上摘下就能进行吊卡规格、品种的更换,以减少钻井作业时所需吊卡的规格、品种,减低钻井成本,方便油田工人操作,便于管理。
附图说明:
下面结合附图和实施例对本实用新型作进一步说明。
图1是本实用新型一个实施例的结构示图。
具体实施方式:
一种新型液压吊卡,包括吊卡主体1,吊卡主体的通孔内镶嵌有套筒2,套筒为剖分式或多片式,可以通过更换套筒,使一个吊卡可以适用所有规型号的管柱。

Claims (2)
