    摘要： An improved grouting method and arrangement using aqueous solutions of alkali silicate materials confined between a pair of pile seal assemblies in sealing the annular space formed between either a jacket leg or pile sleeve and a pile driven therethrough or similar annular space of an offshore platform to support a column of grout thereon so that the annular space may ultimately be filled with grouting material.

    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.

    摘要翻译： 公开了一种用于在井中固定套管的方法。 该方法包括将壳体降低到井筒中，将装置安装在导管上，然后将安装的装置和导管降低到壳体内的预定位置。 然后启动装置并且将流体压力施加到装置，以将装置与先前插入壳体中的壳体或适配器互锁。 持续的流体压力使密封件膨胀以隔离外壳的两个区域。 然后进行固井操作，然后关闭装置。 优选地，可以检索导管以便重新使用。

    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.

    摘要： A removable plug for the J-tube of an offshore platform or marine structure comprising a plug housing, plug body releasably retained with the plug housing, and shear type threaded fastening means retaining the plug body within the plug housing. The plug body may comprise a buoyant plug body to assist in the retrieval of the plug body after the removal thereof from the plug housing.
