Wellhead completion apparatus includes a wellhead member (11) having an upper supporting shoulder (24) and a lower landing shoulder (26). A running tool (30) is releasably connected to a tubing hanger (36) for lowering and landing the tubing hanger (36) on the wellhead member (11). A fluid coupling (66,68,70) is provided between the running tool (30) and the tubing hanger (36). Another fluid coupling (17,60,84) is provided between the tubing hanger (36) and the wellhead member (11). The running tool (30) has a body (31) connected to the tubing hanger (36) and an outer sleeve (46) of the running tool (30) is adapted for initial seating on upper supporting shoulder (24) of the wellhead member (11). After the initial seating of sleeve (46) on upper supporting shoulder (24), running tool (30) and tubing hanger (36) are moved downwardly relative to external sleeve (46) for landing of the tubing hanger (36) onto the lower landing shoulder (26) of the wellhead member (11). Hydraulic fluid is provided from the running tool (30) to the tubing hanger (36) during lowering of the tubing hanger (36) as shown in Figure 5. Upon downward movement of tubing hanger (36) after the seating of running tool sleeve (46) on upper supporting shoulder (24) the supply of fluid is transferred from the tubing hanger (30) to the wellhead member (11) as shown in Figure 6. The auxiliary control fluid passage (62) to the running tool (30) is blocked by the wellhead ring (17) defining the lower landing shoulder (26). An embodiment shown in Figures 7-9 permits a wellhead ring (17A) which is secured to the wellhead member (11A) to be sealed by O-rings (76A, 78A) along planar surfaces (13A, 75A) about the control fluid passage (22A) in the wellhead member (11A).

Appareil de complétion d'une tête de puits comprenant un élément de tête de puits (11) qui a un épaulement d'appui supérieur (24) et un épaulement de pose inférieur (26). Un outil de pose (30) est raccordé de façon amovible à une suspension des tubes de production (36) sur l'élément de tête de puits (11). Un accouplement hydraulique (66,68,70) est placé entre l'outil de pose (30) et la suspension des tubes de production (36). Un autre accouplement hydraulique (17,60,84) est placé entre la suspension des tubes de production (36) et l'élément de tête de puits (11). L'outil de pose (30) a un corps (31) raccordé à la suspension des tubes de production (36), et un manchon extérieur (46) de l'outil de pose (30) est adapté pour l'ajustement initial sur l'épaulement d'appui supérieur (24) de l'élément de tête de puits (11). Après l'ajustement initial du manchon (46) sur l'épaulement d'appui supérieur (24), l'outil de pose (30) et la suspension des tubes de production (36) sont descendus relativement au manchon extérieur (46) en vue de la pose de la suspension des tubes de production (36) sur l'épaulement de pose inférieur (26) de l'élément de tête de puits (11). Un fluide hydraulique est fourni de l'outil de pose (30) à la suspension des tubes de production (36) durant la descente de la suspension (36) selon les indications de la figure 5. Quand la suspension des tubes de production (36) se met à descendre, après l'ajustement du manchon (46) de l'outil de pose sur l'épaulement d'appui supérieur (24), la fourniture du fluide est transférée de la suspension des tubes (36) à l'élément de tête de puits (11) selon les indications de la figure 6. Le passage auxiliaire du fluide de commande (62) à l'outil de pose (30) est bloqué par l'anneau de tête de puits (17) qui définit l'épaulement de pose inférieur (26). Une application montrée dans les figures 7-9 permet un anneau de tête de puits (17A) qui est fixé à l'élément de tête de puits (11A) dont l'étanchéité est assurée par des joints toriques (76A, 78A) le long de surfaces planes (13A, 75A) autour du passage du fluide de commande (22A) dans l'élément de tête de puits (11A).
