摘要： Devices and methods for setting a packer inside a wellbore with little appreciable reduction of the useable area of the wellbore. The outer casing or liner of the wellbore contains one or more integrated casing coupler joints having an increased diameter chamber portion. A large bore packing element is carried within the increased diameter chamber portion. The packing element may be selectively actuated to form a seal against an interior tubular member. Because the packing element is located within the chamber portion of the casing coupler, the packer may be set while saving useable cross-sectional area within the casing.

摘要翻译： 在井眼内设置封隔器的装置和方法，几乎不会明显减少井筒的可用面积。 井眼的外壳或衬套包含一个或多个具有增加直径的室部分的集成的套管联接器接头。 大口径包装元件被承载在增加直径的腔室部分内。 包装元件可以被选择性地致动以形成抵靠内部管状构件的密封。 因为包装元件位于套管联接器的腔室部分内，所以可以设置封隔器，同时在壳体内节省可用的横截面积。

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 coupler for gravel packing completions comprising an annular member having an upper end, a lower end, at least one flange disposed along an inner wall surface of the annular member intermediate the upper and lower ends, and at least one deformable portion is disclosed. The coupler may be used to connect one or more screens to a base pipe in a gravel packing completion by deforming the deformable portion such as by passing a swage over the outer wall surface of the annular member. In a similar manner, the coupler may also be used to connect a gravel packing completion component, such as an inflow control device to the base pipe of the gravel packing completion, to contemporaneously connect a screen section and a gravel packing completion component to the base pipe.

摘要： A screen assembly has a material that conforms to the borehole shape after insertion. The assembly comprises a compliant layer that takes the borehole shape on expansion. The outer layer is formed having holes to permit production flow. The selected conforming material swells with heat, and in one non-limiting embodiment comprises a shape memory foam that is thermoset or thermoplastic. Heat is provided by supplying a fuel (including an oxidant) to a catalyst in close proximity to the compliant layer so that the product from the catalytic reaction is heated steam which contacts and deploys the conforming material. The base pipe can have a screen over it to act as an underlayment for support of the conforming layer or alternatively for screening.

摘要： A screen that conforms to the borehole shape after expansion is disclosed. The screen comprises a compliant outer layer that takes the borehole shape on expansion. The outer layer is formed having holes to permit production flow. The material that is selected preferably swells with prolonged contact to well fluids to further close off annular gaps after expansion. In an alternative embodiment, the screen is not expanded and the swelling of the material alone closes off annular gaps. The outer sleeve is placed over the screen and the screen is placed on a base pipe and initially expanded from within the base pipe to secure the components of the screen assembly for running downhole, while minimizing or eliminating any welding among the layers. A variety of expansion tools can be used to expand the screen or screens downhole.

摘要： In one embodiment telescoping members are extended to bridge an annular gap either before or after it is cemented. Some of the telescoping members have screens and others have flow passages that can be selectively opened with associated valves to frac an interval in any order desired. The valves are then closed after the frac job and the other telescoping members are made to allow screened flow from the fractured formation. In another embodiment an interval to be gravel packed and fractured has a series of screens and selectively opened valves on a bottom hole assembly such as a liner. One or more external packers are provided. The entire interval is gravel packed at one time followed by packer actuation and then selective opening of ports to conduct a fracture operation in any of the zones defined by the set packers and in any desired order.
