Tool for taking out floating valve element of drilling tool

Abstract

The invention discloses a tool for taking out a floating valve element of a drilling tool. The tool comprises an adjustable support, two hooks, a lead screw, an auxiliary nut and a baffle board, two through holes are formed in the two sides of the adjustable support, the lower parts of the two hooks are hooked on a step of the floating valve element, the upper parts penetrate through the corresponding through holes, extend upwards and are locked by hook nuts, the lower part of the lead screw vertically penetrates through the middle part of the adjustable support and extends downwards, the leadscrew is in transmission connection with the auxiliary nut, the auxiliary nut is arranged at the lower end of the adjustable support and detachably and fixedly connected with the adjustable support through a limiting pin, a baffle is rotatably installed at the lower end of the lead screw and abuts against the step face of a floating valve connector body to serve as a support, and the baffle is limited on the lead screw through a locking nut; and the distance between the baffle and the adjustable support can be adjusted by rotating the lead screw, the adjustable support can drive the two hooksto move upwards, and then the floating valve element is taken out. The tool is simple in structure, convenient to use, safe, reliable and wide in application range.

Description

technical field [0001] The invention relates to the field of oil drilling operations, in particular to a tool for taking out a floating valve core of a drilling tool. Background technique [0002] In the process of drilling, when a kick occurs, in order to prevent the drilling fluid from spraying upward from the water hole of the drilling tool, causing accidents such as blowout or blowout out of control, it is necessary to install a float valve near the drill bit, and the float valve core is installed on the float valve joint. In the body, it is closely matched with it. If it is soaked and eroded by drilling fluid for a long time in the downhole, it is difficult to take out the float valve core in the float valve joint body after use. Contents of the invention [0003] The object of the present invention is to solve the above-mentioned technical problems and provide a drilling tool floating valve core removal tool with reliable structure and convenient use. [0004] In or...
