Description

Technical Field

[0001] The present invention relates to the technical field of oil and gas drilling, and particularly to a top drive elevator inclination angle measuring device. Background Technique

[0002] The full name of the top drive is the top drive drilling device, which is a top drive drilling system. The top drive drilling device can directly rotate the drill pipe from the upper space of the derrick, feed it downward along a special guide rail, and complete various drilling operations such as rotating the drill pipe for drilling, circulating drilling fluid, connecting stands, making and breaking pipe connections, and backreaming.

[0003] At present, the top drive conducts drill pipe handover with other equipment through the top drive elevator. It is necessary to continuously repeat the processes of the elevator tilting forward, tilting backward, and floating (in the middle position), and at the same time, repeat the up and down movement processes of moving above the second floor platform and below to the wellhead. Its movement process is an essential construction procedure. The traditional method is to manually operate the top drive elevator, observe the relative position between the top drive elevator and other equipment with the naked eye, and then try to adjust the relative position between the top drive elevator and other equipment to gradually complete the drill pipe handover. If the operator controls the forward and backward tilting angles of the elevator too large due to misoperation, accidents such as the top drive elevator colliding with the collapse of the second floor platform, the bending deformation of the inclined hydraulic cylinder, and the bending deformation of the elevator are likely to occur, endangering the safety of equipment and personnel and causing serious economic losses.
