    • A method for forming a gravel pack in a washed-out interval is provided where a borehole penetrates an unconsolidated or loosely consolidated oil or gas reservoir which is likely to introduce substantial amounts of sand into the borehole. After perforating the borehole's casing at a washed-out interval of the formation, sand is introduced into the interval. Afterwards, an aqueous silicate solution is injected into said interval. Next, a spacer volume of a water-immiscible hydrocarbonaceous liquid is introduced into the interval. Thereafter, a water-miscible organic solvent containing an alkylpolysilicate is injected into the interval. A permeability retaining silica cement is formed in the interval thereby making a gravel pack. Injection of the aqueous silicate and organic solvent containing an alkylpolysilicate is continued until the interval has been consolidated by the silica cement to an extent sufficient to exclude sand and formation fines.
    • 提供了一种在冲洗间隔中形成砾石充填物的方法,其中钻孔穿透可能将大量砂子引入钻孔中的未固结或松散固结的油或储气罐。 在地层的冲洗间隔穿孔钻孔套管后,将沙子引入间隔区。 之后,将硅酸水溶液注入所述间隔。 接下来,将间隔体积的水不混溶的含烃液体引入到间隔区内。 此后,将含有硅烷基硅烷的水混溶性有机溶剂注入间隔区。 在间隔中形成渗透性保持硅胶,从而制成砾石包装。 注入硅酸水溶液和含有烷基聚硅酸的有机溶剂,直到间隔已被二氧化硅胶粘剂固化至足以排除砂和成矿细粒的程度。

    • Systems and methods for providing zonal isolation in a hydrocarbon well include or utilize a tubular assembly having an upstream manifold, a gravel packing conduit, a transport conduit, a leak-off conduit, and a downstream flow path. The tubular assembly is adapted to receive a gravel-laden slurry and to direct at least a portion of the same to the gravel packing conduit. The gravel-laden slurry exiting the gravel packing conduit packs the annulus between the tubular assembly and the wellbore by dehydrating at least in part through the leak-off conduit. The leak-off conduit is further gravel-packed by the gravel-laden slurry received by the tubular assembly. The leak-off conduit is dehydrated through a flow control valve. Together, the gravel packed annulus and the gravel packed leak-off conduit provide a gravel-based zonal isolation system.
    • 用于在烃井中提供区域分离的系统和方法包括或利用具有上游歧管,砾石填充管道,输送管道,泄漏管道和下游流动路径的管状组件。 管状组件适于容纳装有砾石的浆料并将其至少一部分引导至砾石填充导管。 离开砾石充填管道的砾石充满泥浆通过至少部分地通过泄漏管道脱水来包裹管状组件和井眼之间的环状空间。 泄漏管道被由管状组件接收的由砾石充满的浆料进一步砾石填充。 泄漏管道通过流量控制阀脱水。 一起,砾石填充的环带和砾石包装的泄漏管道提供了一个基于砾石的区域隔离系统。

    • Systems and methods for managing pressures present in an annular space defined between casing strings contained within a subterranean well. These systems and methods may include providing a pressure distribution casing that includes a plurality of pressure distribution passages and distributing fluids present within the annular space along a length of the pressure distribution casing and/or between the annular space and the subterranean formation using a portion of the plurality of pressure distribution passages. Pressure distribution passages may be present on an inner surface of the pressure distribution casing, on an outer surface of the pressure distribution casing, and/or within a wall of the pressure distribution casing and may distribute the fluids along the length of the pressure distribution casing without distributing the fluids across and/or through a wall of the pressure distribution casing, such as between the inner surface and the outer surface of the pressure distribution casing.

    • A method associated with the production of hydrocarbons is described. The method includes drilling a wellbore using a drilling fluid, conditioning the drilling fluid, running a production string in the wellbore and gravel packing an interval of the wellbore with a carrier fluid. The production string includes a joint assembly comprising a main body portion having primary and secondary fluid flow paths, wherein the main body portion is attached to a load sleeve assembly at one end and a torque sleeve assembly at the opposite end, the load sleeve assembly having at least one transport conduit and at least one packing conduit disposed therethrough. The main body portion may include a sand control device, a packer, or other well tool for use in a downhole environment. The joint assembly also includes a coupling assembly having a manifold region in fluid flow communication with the second fluid flow path of the main body portion and facilitating the make-up of first and second joint assemblies with a single connection.
