Abstract

The invention discloses a well testing retaining fork, which belongs to the technical field of well testing construction tools. The first fixed seat and the second fixed seat are fixed on the installation section, and the rotating shaft includes a positive thread section, a first optical axis section, a knurled section, a second optical axis section and a reverse thread section in turn, and the knurled section is located on the first optical axis section. Between the shaft section and the second optical axis section, the rotation shaft runs through the first fixed seat and the second fixed seat, the positive thread section is threaded with the first movable block, and the reverse thread section is threaded with the second movable block, The first movable block is slidably connected to the installation section through the first slider, and the second movable block is slidably connected to the installation section through the second slider. The invention is simple in structure and reasonable in design, can conveniently and flexibly clamp well testing instruments of various sizes on the blowout preventer nozzle, has strong flexibility, and can greatly reduce labor intensity.

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...
