Novel trailing drilling platform

Abstract

The invention relates to a novel trailing drilling platform which belongs to the field of oil field drilling-repairing machine corollary equipment and comprises a top assembly, a bottom assembly and a drilling platform main body formed by upright posts sleeved together with circular or rectangular tubes. The novel trailing drilling platform is characterized in that a connecting device is arrangedat one end of the bottom assembly and connected with the top assembly through a sliding plate and forms a triangular rigid frame structure with the upright posts; the connecting device is in sliding connection with a catwalk which can be partly retracted to the drilling platform and connected and fixed with the connecting device and the bottom assembly of the drilling platform through lug plates and pin rolls on the catwalk into a whole to form a frame girder, and a towing pin connected with a towing vehicle is arranged at the other end of the catwalk; the bottom assembly on the other side ofthe drilling platform is provided with a wind support saddle, a pair of raising oil cylinders is arranged on the crossed part of the bottom assembly and the upright posts and connected with the end part of a one-line double-bridge wheel carrier. When the novel trailing drilling platform is moved, an upper drilling room of the drilling platform, a rotating disk, a blowout preventer hoisting device, a hydraulic station, a blowout preventer and the like do not need to be dismounted. The removal time is reduced to 2-3 hours from the prior 4-50 hours, the operating efficiency is improved and the operating cost is reduced.

Description

Technical field: [0001] The invention relates to a new type of towed drilling platform suitable for matching oil and gas field drilling rigs and workover rigs. Background technique: [0002] With the continuous improvement of drilling technology, the transportation performance of drilling and workover rigs has become an important factor affecting the efficiency of drilling and workover operations. Especially in drilling and workover operations in oil-rich areas, it is required that drilling and workover rigs need only a few hours or less to complete the transition between well sites of several kilometers or less. Drilling and workover rig The rig floor is the working platform for drilling and workover operations, and its moving mode affects the transition efficiency of the entire drilling rig. At present, the structure of telescopic drill floor equipped with various trailers and vehicle-mounted drilling and repairing machines in domestic oil fields is mostly: top assembly, ...
