Abstract

The invention discloses a well drilling device for double-wellhead operation. The well drilling device comprises a base of a drilling machine, wherein a drilling machine moving device is arranged on each support leg at the lower end of the base; a blowout preventer hoisting and moving system is arranged on the lower surface of the table-board of the base; the blowout preventer hoisting and moving system is used for hoisting a blowout preventer; a derrick is fixedly connected to the table-board of the base; a crown block is arranged on the top end of the derrick; two groups of travelling blocks are arranged on the crown block in a hoisting manner. The well drilling device disclosed by the invention realizes synchronous well drilling, sleeve setting, well cementation, waiting on cement setting, blowout preventer installation and pressure test operation on a plurality of well sites; various operations of well drilling production operation and assisted operations are organized together to be carried out on the well sites by adopting an offline operation manner, so that the well construction period is shortened, the production efficiency is improved and the well drilling cost is reduced.

Description

technical field [0001] The invention belongs to the technical field of drilling equipment, and relates to a drilling device for double wellhead operation. Background technique [0002] When the existing drilling equipment is performing (cluster type) drilling operations, it is limited to connecting the drill pipe stand, tripping, connecting the casing column and running the casing, cementing and waiting for coagulation, BOP installation and installation at a single wellhead. In the pressure test operation, the above five operations are repeated and alternately performed during the entire drilling process. Since the above five operations need to be prepared for the alternation, it will consume a lot of manpower, material resources and time; if the offline operation method is used to organize the above drilling production operations and auxiliary operations to be carried out across multiple wellheads, it will be difficult. Shorten the establishment cycle, improve production e...
