摘要： A subsurface safety valve assembly for controlling fluid flow in a wellbore. In one embodiment, the subsurface safety valve assembly includes a tubular member having a longitudinal bore extending therethrough, a flapper removably connected to the tubular member. The flapper is configured to pivot against the tubular member between an open position and a closed position. The subsurface safety valve assembly further includes a flow tube disposed inside the tubular member and a shear sleeve having an upper end and a lower end. The upper end of the shear sleeve is positioned against a lower end of the flow tube to form a first seal between the upper end of the shear sleeve and the lower end of the flow tube.

摘要： A downhole drilling apparatus for interconnection in a casing or liner string having a drill bit disposed thereon for enabling the drilling of intersecting wellbores without removal of the drill bit is disclosed. In a disclosed embodiment, the apparatus comprises a housing having a window. A whipstock is disposed within the housing. Between the window and the whipstock is a filler. The whipstock and the filler define a central bore providing a fluid path through the apparatus. A back pressure valve may be disposed within the central bore to prevent back flow of fluids through the apparatus. Once the total depth of an initial wellbore is reached, the casing or liner string, including the apparatus, may be cemented in place. Thereafter, an intersecting wellbore may be drilled by laterally deflecting a second drill bit with the whipstock through the window of the housing.

摘要： A cement mixing and pumping simulator comprises actual and virtual equipment. In response to an operator controlling this equipment, signals representing operating characteristics of a cement mixing system realistically represented by the actual and virtual equipment are generated. These signals are communicated for displaying the operating characteristics to the operator so that the operator obtains real-time responses to the operator's control of the actual and virtual equipment. A method of simulating operation of a cement mixing system comprises: operating, at a master control location within actual equipment of the cement mixing system, at least one actual control device of the cement mixing system; operating, at the respective location of each, at least one of the actual equipment located away from the master control location; determining characteristics of material flow through the cement mixing system in response to the operation of the at least one actual control device and the at least one actual equipment without actually flowing material through the cement mixing system; and displaying the determined characteristics in real time with the operating and determining steps. This method preferably further comprises recording data identifying a performance evaluation of an operator in response to a comparison between at least one of the determined material flow characteristics and a corresponding predetermined characteristic.
