摘要： A millable bridge plug system includes a mandrel, an upper cap end, a sealing member, ring members, cone assemblies, slip devices and a lower cap end. The sealing member, ring members, cone assemblies and slip devices are positioned on and around the mandrel. Ring members abut against an upper end and a lower end of the sealing member. The other sides of the ring members abut against the cone assemblies, and the cone assemblies engage respective slip devices. The upper cap end attaches to the first slip device, and the lower cap end attaches to the second slip device. The lower cap end holds the mandrel and second slip device together to resist rotation during milling.

摘要： A millable bridge plug system includes a mandrel, a sealing member, ring members, cone assemblies, and slip devices. The sealing member, ring members, cone assemblies and slip devices are positioned on and around the mandrel. Ring members push against an upper end and lower end of the sealing member. The sealing member has a surface interface contacting each of the ring members so that pressure from the ring members is exerted according to contact along the surface interface. The surface interface can have a curvature or be a double radiused surface. The ring members are pushed against the cone assemblies, and the ring members have ring surface interfaces contacting the cone assemblies. The pressure from the cone assemblies is exerted according to contact along the ring surface interface of the ring members. Coordination of the surface interfaces and ring surface interfaces control pressure to insure improved sealing against the wellbore.

摘要： A millable bridge plug system includes a mandrel having an upper portion and a lower portion, a shearing member attached at said upper portion of the mandrel, a sealing member, ring members, cone assemblies, slip devices, and a cap member at a lower portion of the mandrel. The shear member and the cap member are modular so that one bridge plug interchangeably connects to another bridge plug. The shear members are compatible with cap members of other bridge plugs. The shear member and the cap member further include a locking mechanism for rotational engagement by protrusions on the cap member being fit into the shear member and a locking mechanism for triggering a spring loaded lock into a groove on the cap member.

摘要： A frac sleeve system includes an outer sleeve with openings, an inner sleeve with ports, a pressure seat, a bottom locking device and a spring device. In a closed configuration of the inner sleeve, the openings and ports are not aligned for any fluid connection. In an opened configuration, at least one opening is aligned with at least one port for a fluid connection through the system. The inner sleeve shifts back and forth between configurations according to the pressure seat and the spring. The interaction of a guide pin on the outer sleeve and the guide slot on the inner sleeve controls the rotational and longitudinal movement of the inner sleeve along the common axis of the inner sleeve and outer sleeve so that there is unlimited shifting between configurations. The locking devices and spring device are also reuseable for the multiple shifting.

摘要： A millable bridge plug system includes a mandrel having an upper portion and a lower portion with an interlock, a shearing member attached at the upper portion, a sealing member, ring members, cone assemblies, slip devices, and an interlocking drill member at a lower portion of the mandrel. The interlock of the mandrel and the interlocking drill member are modular so that one bridge plug interchangeably connects to another bridge plug. The interlocks are compatible with interlocking drill members of other bridge plugs and vice versa. The interlocking drill member has rotatable cutting blades to drill through sand and other debris between the interlocking drill member and the next bridge plug to be removed. A milling unit can drive rotation of the interlocking drill member to reach the next bridge plug for removal, until the interlocking drill member engages the adjacent interlock of the next bridge plug to be removed.

摘要： The system and method for hydraulic fracturing includes a downhole tool with a sub, a sleeve, a ball seat support, and a ball seat holder. A ball dropped through the wellbore sits on the ball interface of the ball seat holder. Fluid flowing through the system pushes the ball against the ball interface, causing the ball seat holder to slide through the ball seat support and the ball interface to clamp the ball. A ball matches only a particular ball interface. Additional pressure forms a seal of the ball, the ball seat holder, and the ball seat support and moves the sleeve to slide through the sub and expose the throughbore to the annulus for the fracturing. Contact distributed between the ball, ball interface of the ball seat holder, and ball seat support withstands the temperature and pressure of the fracturing without deformation or failure of the ball.
摘要翻译：用于水力压裂的系统和方法包括具有子，套筒，球座支撑件和球座支架的井下工具。通过井筒落下的球坐在球座座的球界面上。流经系统的流体将球推向球界面，导致球座座通过球座支撑和球界面滑动以夹紧球。一个球只匹配一个特定的球界面。附加压力形成球，球座保持器和球座支撑件的密封件，并且移动套筒以滑动穿过子部分，并将通孔暴露于环形空间以进行压裂。分配在球座，球座座之间的球接触点和球座支撑件之间的接触能承受压裂的温度和压力，而不会发生球的失效或失效。
