    摘要: A method is disclosed for the cementing of casing in a well. The method involves lowering the casing into the wellbore, installing a device on a conduit and thereafter lowering the installed device and conduit to a predetermined position within the casing. The device is then actuated and fluid pressure is applied to the device to interlock the device with either the casing or an adapter previously inserted in the casing. Continued fluid pressure distends a seal member to isolate two regions of the casing. A cementing operation is then performed followed by closure of the device. Preferably, the conduit may then be retrieved for reuse.A device is disclosed for cementing a casing within a wellbore. The device includes a body for occupying a substantial portion of the interior of a region of the casing. The body is connectable to a conduit thereabove and has an external hydraulic seal to pack off the casing. The body also has an interlock system to interlock with the casing to prevent upper movement of the device during subsequent cementing operations. Appropriate valving is also present in the device to enable the proper sequential actuation of the seal, interlock system and cementing accessories.

    摘要: An inflatable packer and method for sealing the annulus between an outer member and a pile driven therethrough. The inflatable packer comprises a packer housing, first and second guide rings secured within the packer housing, and an inflatable packer member having its ends secured from axial movement within the packer housing by the first and second guide rings. The method of sealing an annulus between an outer member and a pile driven therethrough comprises the steps of sealing the annulus at a first location, injecting gas into the annulus to expel any material contained within the annulus, sealing the annulus at a second location which is free of material, venting the annulus between the first location and second location while maintaining the annulus free of any material, and injecting grouting material into the annulus between the first location and second location.
