    摘要： A method of sealing casing or liners in a wellbore is described. The stands of casing or liner receive a jacket bonded to the outer surface. Preferably, the jacket is a rubber compound bonded to the outer wall. The formulation responds to well fluids to swell at a predetermined rate. The casing or liner can also be expanded with a swage preferably prior to the onset of significant jacket swelling. Packers and sealing hangers can be optionally added at the extremes of the casing or liner string to further secure against channeling between adjacent formations.

    摘要： An apparatus to protect the mounting area of casing when subsequently attaching a tubular is disclosed. A sleeve that defines a sealed cavity having a loose incompressible material inside covers the mounting location on the casing. The cementing of the casing takes place through the sleeve. After the cementing, the sleeve is drilled out and the incompressible material is removed to the surface with the drill cuttings. A tubular is inserted in the casing and is preferably expanded into sealing contact with the mounting location on the casing. At the end of expansion, the run in shoe on the tubular is retrieved.

    摘要： An apparatus to protect the mounting area of casing and a locating profile and optionally a sliding sleeve valve and a flow path from the outside of the valve to the annulus when subsequent attachment of an expanded liner is intended and the expanded liner is to be cemented in place. A barrier sleeve, nose, and outer sleeve define a sealed cavity having a loose incompressible material inside that covers the mounting location on the casing. A locating profile and an optional sliding sleeve valve and a flow path from the outside of the valve to the annulus can be provided. The cementing of the casing takes place through the barrier sleeve. After the cementing, the sleeve and nose are drilled out and the incompressible material is removed to the surface with the drill cuttings. A liner is inserted in the casing and is preferably expanded into sealing contact.

    摘要： A variety of approaches to reducing or eliminating “end effect” or the tendency of tubular ends to reduce in diameter after expansion are disclosed. Some involve pre-bending the ends outwardly while others involve removing material internally or/and externally near the ends. Yet other approaches feature weakening the ends in other ways including penetration of the tubular material using openings of various shapes including slots or/and holes where the openings are between the tube ends or where they can extend on one or both ends all the way to the end of the tubular. Inserts that are softer than the tube material can be placed near the ends. If there is an end effect, then the protruding material can be pushed out of the way or broken off.

    摘要： The disclosure relates to an improved flapper type saftey valve and valve housing for use in subterranean wells wherein the flapper valve is actuated from a horizontal closed position to a vertical open position by contact with a downwardly moving actuating sleeve. The top surface of the valve is elevated so that the bottom edge of the actuating sleeve always contacts the flapper valve at a position spaced from the axis of the pivot mounting, thereby assuring that the opening force applied to the flapper valve has a maximum moment arm in order to overcome any fluid pressure differential existing across the flapper valve. The valve is mounted in an eccentic bore on an eccentric mounting base and fully opened flapper valve provides maximum flow area through the valve.

    摘要翻译： 本公开涉及一种用于地下井的改进的挡板式安全阀和阀壳体，其中挡板阀通过与向下移动的致动套筒接触而从水平关闭位置致动到垂直打开位置。 阀的上表面被升高，使得致动套筒的底部边缘在与枢转安装件的轴线间隔开的位置处始终接触挡板阀，从而确保施加到挡板阀的打开力具有最大力矩臂 以克服跨过挡板阀存在的任何流体压力差。 阀安装在偏心安装底座上的偏心孔中，完全打开的挡板阀通过阀门提供最大流动面积。
