摘要： A submarine well drilling and geological exploration station includes an inner pressure hull specially configured for submerged drilling and exploration and an outer fairing hull of conventional submarine design. The pressure hull is divided by an air lock into an atmospheric pressure chamber and a superatmospheric pressure chamber. Ballast tanks are arranged so that the station may be rotated from a horizontal in-transit orientation to a vertical drilling and exploration orientation. The superatmospheric chamber permits exploration and drilling operations therein in the vertical orientation. A tandem propeller system is used to stabilize the station in position while in the vertical orientation and to propel the station from location to location while submerged in the horizontal orientation.

摘要： A floating, offshore drilling and/or production platform is equipped with a rail-mounted transport system that can be positioned at a plurality of selected positions over the well bay of the vessel. The transport system can move a drilling riser with a drilling riser tensioner system and a blowout preventer from one drilling location to another without removing them from the well bay of the vessel. Using the transport system, the drilling riser is lifted just clear of a first well head and positioned over an adjacent, second well head using guidelines. The transport system may then move the upper end of the drilling riser (together with its attached tensioner and BOP) to a second drilling location. A dummy wellhead may be provided on the seafloor in order to secure the lower end of the drilling riser without removing it from the sea while production risers are being installed.

摘要： Apparatus for drilling and completing hydrocarbon producing wells in waters of a substantial depth and for the redrilling and servicing of such wells. The apparatus includes a surface drilling rig, normally of the semi-submersible type, and a submersible drilling rig. The surface drilling rig sets and cements a conductor pipe into position in the floor of the body of water and may install other pipe stubs therein, such as a surface pipe, to initially begin the drilling operation. The submersible drilling rig, which is more easily transported in sections, is then assembled and lowered into position over the conductor pipe by filling ballast tanks located within the submersible drilling rig. The submersible drilling rig, which is supplied by means of an umbilical cord from the surface drilling rig is coupled to the conductor pipe in a watertight manner. The drilling operation begins from the interior of the submersible drilling rig, which houses well drilling equipment as well as logging and well completion equipment. The main working area of the crew in the submersible drilling rig is below the surface of the body of water but a considerable distance from the floor of the body of water. Therefore, the projection from the working area down to the conductor pipe at the floor of the body of water is a stingray type of design, which allows for connection to the conductor pipe. From the work quarters, a periscoping device can be extended up to the surface drilling rig for changing crews, receiving supplies, etc., and setting and cementing production casting or redrilling operations. If the drilled well becomes a production well, the submersible drilling rig will install production control valves which are left located on the floor of the body of water and thereafter move on to a new location.
摘要翻译：用于在相当深度的水域钻井和完成碳氢化合物生产井并用于重新钻井和维修这种井的装置。该设备包括通常为半潜式的地面钻机和潜水钻机。地面钻机将导管设置并固定在水体底部的适当位置，并且可以在其中安装其它管柱，例如表面管，以便最初开始钻孔操作。然后通过填充位于潜水钻机内的压载舱，将更容易运输的潜水钻机组装并降低到导体管上方的位置。通过来自地面钻机的脐带提供的潜水钻机以水密的方式联接到导管上。钻井作业从潜水钻机的内部开始，该钻机装有钻井设备以及测井和完井设备。潜水钻机中船员的主要工作区域位于水体表面之下，但距离水体地面相当距离。因此，从工作区域到水体底部的导体管的投影是一种黄貂皮设计，允许连接到导体管。从工作区开始，一个潜艇装置可以扩展到地面钻机，以改变船员，接收物资等，以及设置和固井生产铸造或再钻机操作。如果钻井成为生产井，潜水钻机将安装生产控制阀，其位于水体的地板上，然后移动到新的位置。
