摘要： A process for drilling and completing multiple subterranean wells from a common well bore (9) and an assembly for guiding a drill string during drilling and casing during completion of such multiple wells.
The assembly comprises a wellhead (6) located at or near the surface of the earth and positioned over the common well bore (9), at least two tubulars (30, 34) positioned within the common well bore, and means positioned at said wellhead (6) for segregating and supporting the tubulars.
In accordance with the process, at least one subterranean well bore is drilled through one of the tubulars (30, 34) 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 (9). Other subterranean well bores can be drilled in a similar manner through other tubulars of the assembly.摘要翻译： 一种用于钻探和完成从一个共同的井孔（9），并在装配用于搜索多个井完成期间引导钻井和套管中的钻柱多口地下井的过程。 该组件包括位于或在地球的表面附近，并定位在共同的井孔（9），至少两个管件（30，34）的共同的井孔内定位的装置，以及在所述井口定位井口（6） （6）用于分拣和支撑管件。 与过程雅舞蹈，至少一个地下井孔穿过管件中的一个（30，34）钻出和到地下地层中和烃可以从经由生产套管和/或生产管道定位在所述地下地层的表面而制造 地下井孔（9）内。 其它地下井孔可以以类似的方式通过所述组件的其它管件钻出。

摘要： Appareil et procédé permettant l'alignement et la connexion sous l'eau de deux tuyaux utilisés dans le forage directionnel et en particulier dans les traversées de plage sans tranchée. Un câble d'alignement (45) est connecté entre les extrémités des deux tuyaux (30, 31) et est tendu pour les amener en alignement axial. Une plate-forme (50) de support rigide est positionnée sur le fond de la mer. Des brides (62, 63, 72, 73) de fixation sont montées sur la plate-forme pour aligner les deux tuyaux. Pour visser les tuyaux, l'un des deux tuyaux tourne autour de l'axe de jonction.

摘要： Procédé pour établir une jonction "intégrale" entre le fond marin (1) et un tunnel (3) ou une partie de celui-ci, situé sous le fond marin. Le tunnel est creusé à l'explosif ou foré depuis la formation de roches et le percement du tunnel s'arrête le plus près possible de la surface du fond marin sans mettre en danger le personnel et le matériel. La jonction entre le fond marin et le tunnel est réalisée en forant depuis le fond marin (1) un certain nombre de trous (8) débouchant dans le tunnel (3) et possédant une section traversante totale qui, dans le domaine hydrodynamique, correspond au moins à la section du tunnel.

摘要： A conductor guide arrangement is provided for conductors or tubular conduits (10) of an offshore well platform having a jacket (20) with an interior pile (4) for extending from a sea bed (1) to above a water level (3) which is over the sea bed. The conductor guide arrangement may include a first guide means (20) which comprises a plurality of vertically spaced supports which hold the conductors (10) within the pile (4) and is assembled in a plurality of sections wherein an upper support of each section is provided with removable bolt-on units for supporting the first guide means (20) as successive sections are joined thereto. The conductor guide arrangement may include a second guide means (30) comprising a pair of circular plates which are positioned to rotate within an opening in a lower deck (6) of the platform and which are connected together and define a plurality of passages for receiving the conductors (10) that extend in the pile (4). The connected plates are temporarily attached to the lower deck (6) for transport so that the second guide means (20) can be detached and rotated to align the passages with the intended positions for the conductors (10), after which the second guide means (20) is permanently attached to the lower deck (6). The conductor guide arrangement may include a third guide means (40) which comprises a plurality of radially extending beams (44) and is supported on an upper deck (8) of the platform. The third guide means (40) also has passages for access to the conductors (10) and it too can be rotated into a position of alignment with the conductors (10) and thereafter permanently fixed to the upper deck (8).

摘要： An apparatus for deflecting a tubular string (3) preferably compπsing at least one side nozzle (3b2) near the lower end of a first tubular string. The nozzle permits passage of a fluid therethrough from the ftrst tubular string bore and deflects the first tubular string in a substantially horizontal direction. A second tubular string (2) may be lowered over the deflected first tubular string The second tubular string and the first tubular string are preferably lowered into the sea floor (B) for maintaining their deflection. A method for deflecting a first tubular string and securing the first tubular string in the deflected state preferably comprises lowering the first tubular string axially so that the lower end of the first tubular string is near the sea floor. Preferably, a fluid, such as seawater, is propelled down through the bore of the first tubular string and through at least one side nozzle near the lower end of the first tubular, wherein the fluid moving through the side nozzle deflects the first tubular string. The first tubular string end is preferably lowered into the sea floor for maintaining the deflection of the first tubular string. A second tubular string may then be slidably lowered over the first tubular string for deflecting the second tubular string.
