摘要： A method of drilling an offshore underwater well comprising the steps of installing a riser conduit so that it is substantially vertically supported at a production deck. The riser conduit deviates progressively further from the vertical with increasing sea depth, so that its end can be anchored at the seabed by a skid either at an oblique angle so that drilling into the seabed can be carried out at the oblique angle, or horizontally, so that the riser conduit can extend some considerable distance across the seabed before drilling is carried out.

摘要： Two or more opposing and outward facing profiles are fabricated and joined to each other along their outer edges, forming a section of a guide string. The sections of the guide string are secured together in an assembly and lowered into a single conductor. The assembly lands on the bottom of the well and may support its own weight. The guide string defines two separate longitudinal cavities or sections of the well. Each separate cavity allows drilling and installation of casing in the conductor.

A second well bore may be drilled from the first well bore and a first tubular of a multiple well drilling template can be positioned within the first well bore while a second tubular of the template can be positioned within both the first and second well bores. Additionally, a third well bore can be drilled from the first well bore and the first tubular can be further positioned therein. The first and second well bores can penetrate subterranean formation(s) or additional well bore(s) can be drilled from the first, second and/or third well bores so as to penetrate subterranean formations. A second multiple well drilling template may be utilized to drill such additional well bore(s) from the second or third well bores. Fluid is produced from subterranean formation(s) to the surface via said first, second, third and/or additional well bores and/or through production casing and/or tubing positioned therein.

摘要： A process for drilling and completing multiple subterranean wells from a common well bore and an assembly for guiding a drill string during drilling and casing during completion of such multiple wells. The assembly comprises a wellhead located at or near the surface of the earth and positioned over the common well bore, at least two tubulars positioned within the common well bore, and means positioned at said wellhead for segregating and supporting the tubulars. In accordance with the process, at least one subterranean well bore is drilled through one of the tubulars and into a subterranean formation and hydrocarbons can be produced from the subterranean formation to the surface via production casing and/or production tubing positioned within the subterranean well bore. Other subterranean well bores can be drilled in a similar manner through other tubulars of the assembly.

摘要： A system for controlling the deviation of the path of oil or gas well conductor casing at a desired angle, curvature and orientation in the sea bottom stratum through which it is driven from an offshore platform involving the use of conductor guide(s) equipped with longitudinally disposed anti-twist bar(s) fixedly mounted thereon to prevent or arrest any twisting motion along the longitudinal axis of the casing sections which have like, anti-twist bar as the conductor sections are being lowered or driven down from the platform. Motion is arrested by means of the bars on the conductor guide(s) contacting the similar bars fixedly attached to the casing sections being driven through the conductor guides on the platform support structure. By arresting any twisting motion at this relatively elevated point, any undesired twist is minimized in the driven casing sections minimizing any undesired horizontal deviation in the enplacement of the conductor casing which would have otherwise been caused by the twisting. Additionally or alternatively, there can be included a system using a cable or chain and winch drive to either counter-act the twist prior to the arresting of that twist or to move the twist in the opposite direction prior to the arresting of the twist or to independently position the conductor casing in a desired radial direction, so as to further control the horizontal angle at which the deviation occurs.

摘要： A conductor guide assembly for conductors of an offshore well platform having a jacket with an interior pile for extending from a sea bed to above a water level which is over the sea bed. In accordance with one inventive feature, a first guide mechanism comprising a plurality of vertically spaced supports which hold the tubular conduits within the interior pile is assembled in a plurality of sections wherein the upper support of each section is provided with removable bolt-on units for supporting the first guide mechanism as successive sections are joined thereto. In accordance with another inventive feature, a second guide mechanism comprises a pair of circular plates positioned to rotate within a lower deck opening and which are connected together and define a plurality of passages for receiving the plurality of conductors that extend in the interior pile. The connected plates are temporarily attached to the lower deck for transport so that the second guide mechanism can be detached and rotated to align the passages with the intended positions for the conductors whereafter the second guide mechanism is permanently attached to the lower deck. In accordance with another inventive feature, a third guide mechanism comprising a plurality of radially extending beams is supported on an upper deck. The second guide mechanism also has passages for access to the conductors and it too can be rotated into a position of alignment with the conductors and thereafter permanently fixed to the upper deck.

摘要： A method and apparatus for installing a curved well conductor (22) from an offshore marine structure (10) utilizes a leading section of precurved pipe (26) along with a plurality of trailing sections of initially straight pipe (24). The precurved pipe (26) is releasably straightened as the conductor (22) is lowered from the marine structure (10). Upon engagement with the sea floor, the precurved pipe (26) is released to resume its original curvature. The trailing initially straight sections of pipe (24) are then forced to follow a curved path defined by the leading section as the well conductor (22) is driven into the sea floor.

摘要： An angular positional sensor comprises a housing in which is mounted a rotary sensing device including a shaft which mounts a pendulum having relatively low inertia and a balanced member having relatively high inertia and rotatably mounted within the housing adjacent the pendulum member. At least the part of the housing containing the pendulum and the balanced member also contains a liquid to provide a viscous coupling between the pendulum and the balanced member. The arrangement is such, that in use, angular movement of the housing about the longitudinal axis of the shaft causes movement of the rotary sensing device relative to the shaft which is retained stationary by the pendulum which in turn is damped by the balanced member, to produce a signal representative of such angular movement from the rotary sensing device.
