    摘要: An expander tool for expanding a first tubular into a second surrounding tubular within a wellbore. The expander tool first comprises a body. Within the body is an expansion member capable of being actuated outwardly from the body when expansion of the first tubular is desired. In one aspect, the expander tool is a rotary expander tool, and the expansion members define a plurality of rollers. The expander tool further comprises at least one sensor for sensing a downhole condition during expansion of the tubular. The sensors in one aspect include at least one tool for sensing wall dimensions of the first tubular such as inner diameter or wall thickness. Examples include sonic logs, caliper logs, and electromagnetic wall thickness tools. A depth gauge may also be included. In one aspect, a data transmission device is provided between a surface server and the sensors downhole. In this way, the operator at the surface can monitor progress of the expansion operation downhole.

    摘要: An improved expansion assembly for an expander tool is provided. The expander tool is used to expand a surrounding tubular body within a wellbore. Accordingly, a method for expanding a surrounding tubular is also provided. The expansion assembly first comprises a piston disposed within a recess of the expander tool. The top surface of the piston closely receives a pad. The pad is held in close proximity to the top surface of the piston such that it does not rotate about a shaft. This arrangement reduces the geometric size of the expansion assembly, affording a larger inner diameter for the hollow bore of the expander tool itself. At least one reinforcement member is disposed on or within the pad to strengthen the pad during an expansion operation. The reinforcement member is fabricated from a durable material, and is arranged along the pad in the area of contact with the surrounding tubular during an expansion operation.

    摘要: An apparatus and method for expanding a lower string of casing into frictional contact with an upper string of casing, and thereby hanging the lower string of casing onto the upper string of casing is provided. The apparatus essentially defines a lower string of casing having a separation region formed in the top end thereof. The lower string of casing is run into the wellbore, and positioned so that the top end overlaps with the bottom end of an upper string of casing already cemented into the wellbore. The top end of the lower casing string is expanded below the depth of the separation region into frictional contact with the upper string of casing. At the same time, or shortly thereafter, the top end of the upper string of casing is expanded. As the portion of the lower casing string having the separation region is expanded, the casing severs into upper and lower portions. The upper portion can then be removed from the wellbore, leaving a lower string of casing expanded into physical contact with an upper string of casing. The separation region may be formed by heat treating the tubular at the point of desired severance. In another aspect, the separation region may comprise the connection between two tubulars. This involves connecting two tubulars to form the tubular to be expanded downhole. The tubular formed is then lowered into the wellbore and expanded at the connection to separate the tubular.

    摘要: A connector arrangement used for connecting a first tubular to a second tubular. The first tubular member has at least one circumferential ring profile, and the second tubular member has a corresponding number of matching circumferential ring profiles. When the ring profiles of the two tubulars are mated and interlocked, they form separate and independent fluid seals as well as a mechanical lock able to hold the tubulars together during future expansion of the entire tubular and joint. Further, selecting properties of the tubulars such as yield strength and modulus of elasticity or constraining a diameter of one of the tubulars during expansion or compression forms a tight connection due to elastic recovery of the tubulars.

    摘要: A method and apparatus for applying hydraulic treatment and diversion treatment to a wellbore are described. The method involves isolating a wellbore segment using hydraulic seals; applying fluid treatment and perforation diverters within the isolated segment; and scraping a portion of the wellbore after termination of treatment to remove any lodged perforation diverters from the wellbore. A collection chamber may also be provided for collecting used diverters for return to surface following treatment. In one embodiment, diverters used and collected within a first segment may be reused during treatment of a successive wellbore segment.

    摘要: The present invention generally relates to an apparatus for sealing a wellbore. The sealing apparatus includes an expandable tubular body having one or more sealing elements disposed thereon. In one aspect, the sealing elements include swelling and non-swelling sealing elements. Preferably, the swelling sealing elements are made of a swelling elastomer capable of swelling upon activation by an activating agent. The swelling elements may be covered with a protective layer during the run-in. When the tubular body is expanded, the protective layer breaks, thereby exposing the swelling elements to the activating agent. In turn, the swelling elements swell and contact the wellbore to form a fluid tight seal.
