Abstract

The invention provides a roller, a semitrailer and vehicle-mounted continuous pipe well drilling equipment. The roller comprises a rotating shaft, a hub and a rim. The hub is connected to the outer portion of the rotating shaft in a sleeving manner. A manifold is arranged in the hub. A sliding ring is connected to the rotating shaft and is connected with the manifold through a first cable. The rimis of an annular structure defined by multiple wheel sections and is connected to the outer edge of the hub in a sleeving manner, the edges of the two sides of the hub are sleeved with the rim, and therefore the diameter of the hub is increased. The transport requirements of large-pipe-diameter and large-length continuous pipes can be met, the problems of existing roller transporting over width and over height are solved, and the roller is suitable for implementing side tracking work on areas with limited well site areas.

Description

technical field [0001] The invention relates to the technical field of drilling equipment, in particular to a drum, a semi-trailer equipped with the above-mentioned drum, and vehicle-mounted coiled tubing drilling equipment including the above-mentioned semi-trailer. Background technique [0002] Many oil and gas fields at home and abroad have entered the middle and late stages of exploitation. Due to engineering factors such as casing damage and overhaul or geological factors, the remaining oil near the original wellbore cannot be exploited. Sidetracking of old wells can effectively tap the remaining oil and gas, reduce investment costs, and improve production efficiency. recovery factor. In order to improve the economic benefit of old well sidetracking, it is urgent to find a more economical and efficient old well re-drilling technology. [0003] Coiled tubing drilling technology is one of the popular drilling technologies that have been vigorously researched and develope...
