Abstract

The invention discloses a well testing blocking fork and belongs to the technical field of well testing construction tools. The well testing blocking fork comprises a body. The well testing blocking fork is characterized by further comprising a rotating shaft, a first moving block and a second moving block. The body comprises an installing section and a holding section. A first fixing base and a second fixing base are fixed to the installing section. The rotating shaft sequentially comprises a right-hand thread section, a first polish shaft section, a knurling section, a second polish shaft section and a left-hand thread section. The knurling section is located between the first polish shaft section and the second polish shaft section. The rotating shaft penetrates through the first fixingbase and the second fixing base. The right-hand thread section and the first moving block are connected through a thread. The left-hand thread section and the second moving block are connected through a thread. The first moving block is in sliding connection with the installing section through a first sliding block. The second moving block is in sliding connection with the installing section through a second sliding block. The well testing blocking fork is simple in structure, reasonable in design, high in flexibility and capable of greatly reducing labor intensity, and well testing instruments of various sizes can be clamped to a blowout preventing pipe opening in series conveniently and flexibly.

Description

technical field [0001] The invention relates to the technical field of well testing construction tools, in particular to a well testing retaining fork. Background technique [0002] The well testing chock is a well testing tool, which is used in oil and natural gas well testing construction. During the construction of the well test site, the wellhead pressure is high and the gas production rate is high. It is often necessary to lower a long and heavy instrument string into the well. On site, a pulley is hung at an appropriate height directly above the blowout nozzle, and the steel wire is wound into the pulley. Slot, winch post Hand winch, shake the tail cone of the instrument string connected to the end of the winch wire to the mouth of the blowout nozzle, and then slowly lower the instrument string into the blowout prevention pipe to the top of the test valve, this method is directly hoisted into the blowout prevention pipe , the hook of the crane is difficult to align wi...
