摘要： Sealing devices such as packers comprise a shape-memory material having a compressed run-in position or shape and an original expanded position or shape. The shape- memory material may comprise a polyurethane foam material held in the compressed run-in position by an adhesion material that is dissolvable by a fluid. The fluid may be a wellbore fluid already present in the wellbore or a fluid pumped down the wellbore after the sealing device is disposed within the wellbore. The fluid may also be a production fluid from the well. Upon being contacted by the fluid, the adhesion material dissolves and the shape-memory material expands to its original expanded position or shape, thereby sealing and dividing the annulus of the wellbore.

摘要： Filtration devices may include a shape-memory material having a compressed run-in position or shape and an original expanded position or shape. The shape-memory material may include an open cell porous rigid polyurethane foam material held in the compressed run-in position at the temperature below glass transition temperature (T9). The foam material in its compressed run-in position may be covered with a fluid-dissolvable polymeric film and/or a layer of fluid-degradable plastic. Once filtration devices are in place in downhole and are contacted by the fluid for a given amount of time at temperature, the devices may expand and totally conform to the borehole to prevent the production of undesirable solids from the formation.
摘要翻译：过滤装置可包括具有压缩磨合位置或形状以及原始膨胀位置或形状的形状记忆材料。形状记忆材料可以包括在低于玻璃化转变温度（T9）的温度下保持在压缩磨合位置的开孔多孔硬质聚氨酯泡沫材料。处于压缩磨合位置的泡沫材料可以用可流体溶解的聚合物膜和/或流体可降解塑料层覆盖。一旦过滤装置在井下就位并且在温度下与流体接触给定时间量，装置可膨胀并完全符合井眼以防止从地层中产生不希望的固体。

摘要： A flow conduit may have at least one orifice, which conduit is in the vicinity of a flow source. The source is at least partially covered (and flow blocked by) an optional temporary coating or barrier (e.g. filter cake). The flow pathway between the orifice and the source is temporarily blocked with a degradable material. A delayed degradation material layer is present over or covering the degradable material. The delayed degradation material layer degrades at a rate slower than the degradable barrier. The degradable material and delayed degradation material layer disintegrate (e.g. via time, temperature, a solvent). The degradable material optionally produces a product that removes the temporary coating. The method is useful in one context of recovering hydrocarbons where the flow conduit is the casing or liner of the well and the flow source is a subterranean reservoir where the coating is filter cake.

摘要： A flow conduit (10) has at least one orifice (12) is in the vicinity of a flow source. The source is at least partially covered (and flow blocked by) an optional temporary coating or barrier. The flow pathway between the orifice and the source is temporarily blocked with a degradable material or barrier (18). The material disintegrates (e.g. under the influence of time or temperature) to optionally produce a product that removes the temporary coating in the area adjacent the barrier. The method is useful in one non-limiting context of recovering hydrocarbons where the flow conduit is the casing or liner of the well and the flow source is a subterranean reservoir where the temporary coating is a filter cake.

摘要： A method of preparing a solids-pack for use in oilfield completion operations involves staged pumping using two distinct types of carrier fluid with distinct solids loadings during the solids deposition process. The method can be employed in packing of non-vertical oilfield wellbores for formation stabilization, fracture stabilization and/or sand control, particularly around sand exclusion devices. In preferred embodiments the method results in greater uniformity of packing, and also offers the advantage of much more rapid deposition and therefore of completion of the pack phase, reducing overall rig time.

摘要： Solid, particulate dicarboxylic acids are useful as diverting agents in methods for acidizing subterranean formations to improve the uniformity of the acid treatments (acid displacement) by diverting acid to intervals of relatively less permeability. Particularly suitable solid, particulate dicarboxylic acids include, but are not necessarily limited to, those insoluble in both aqueous and hydrocarbon liquids, but which are soluble in mutual solvents or alcohol blends. These acids may have melting points of about 82° to about 149°C, formula molecular weights of from 146 to 400, and mesh sizes of from about 20 mesh to about 400 mesh (about 841 to about 38 microns). Particular dicarboxylic acids that fit this description include, dodecanedioic acid, undecanedioic acid, decanedioic acid, azelaic acid, suberic acid, and mixtures thereof.
