摘要： A screen section is made with variable resistance to flow in the screen material to balance the flow along the screen length. In one variation different discrete zones have screens configured for different percentages of open area while all have the same particle filtration capability. In another variation discrete portions have differing amounts of overlapping screen portions so as to balance flow without affecting the particle size screened. The cross-sectional shape of a wire wrap underlayment for the screen is made closer to trapezoidal to decrease the angle of opening for the incoming flow paths toward the base pipe. In this manner flow resistance is reduced and flow is increased due to reduced turbulence.

摘要： A liner rotates a bit to make more hole. The liner has openings with inserts in them to lend torque resistance to the liner. The inserts have a passage with a send control media in the passage and a seal so that the liner can hold pressure for run in to get proper circulation through the bit. When sufficient hole is made, the liner is hung off an existing cemented tubular and the seal for the passages with the sand control media is removed by a variety of techniques so that the formation can be produced in a single trip.

摘要： A metallic seal for a 90° valve features a generally rectangular shape in section that defines a chamber open to internal pressure that can enlarge the chamber to enhance the sealing effect. Sealing occurs at discrete locations at portions of the seal that are preferably rounded in shape. Overlapping ends that define the entrance to the chamber also are positioned to minimize excessive deflection and resulting plastic deformation that could close off the entrance to the chamber.

摘要： A spacing device is located on a lower end of a debris removal tool. Circulation through the tool extends telescoping members to the top of the debris zone against a bias that retracts the members when there is no flow through the tool. The lowest telescoping member has peripheral slots through which the circulation for the tool takes place. The landing of the tool on top of the debris can be detected by the weight indicator at the surface. The device prevents embedding the lower end of the tool into the debris. Instruments can also determine the scope of the telescoping extension and transmit that value to the surface so that the cleanup tool can be continuously spaced from the moving top of the debris pile by maintaining a target distance for extension of the telescoping assembly.

摘要： A method of centralizing tubulars prior to cementing and subsequent expansion involves using a plurality of telescoping cylinders whose leading or trailing end is closed and which are extended by applied internal pressure in the tubular or some mechanical means. The tubular is expanded from its interior with the cylindrical telescoping members still extended. The cement is pushed all around the tubular due to the centralizers. After the cement is delivered the expansion of the tubular pushes the telescoping members into the borehole wall.

摘要： The annular space around a tubular string has a shape memory material that is in a low profile configuration for run in. After the desired position is obtained and the annulus has cement delivered to fill the annular space, the shape memory device is triggered to revert to an original shape that spans the annulus to seal the tubular and the wellbore sides of the annular space against gas migration through the cement. The structures can have varying run in shapes and can also have original shapes that when the material is triggered will act to displace cement to enhance its compaction on the tubular or the wellbore wall. Combinations of shape memory alloys and polymers are also contemplated to enhance the seal against gas migration.
