摘要： Methods and apparatus for forming metal or metal alloy casings in well bores are provided. A method of the invention comprises the steps of providing and pumping a fluid suspension of a particulate metal or metal alloy into a pipe string within a well bore having a casing forming tool connected thereto. The casing forming tool includes an internal passageway sealingly communicated with the pipe string and with a plurality of radial openings in the tool positioned around the periphery thereof. An internal heater for heating the fluid suspension and melting the particulate metal or metal alloy and an internal rotating impeller for imparting centrifugal force to the fluid suspension are provided in the casing forming tool. Centrifugal force is imparted to the fluid suspension by the rotating impeller whereby the melted particulate metal or metal alloy forms a casing which solidifies on the walls of the well bore.

摘要： A method and apparatus for foaming and then testing the foamed fluid. The apparatus comprises a cylindrical pressure vessel with upper and lower caps. A circular disk with a plurality of openings, which are preferably circular openings, is placed in the pressure vessel. The apparatus also includes a motor with a shaft extending therefrom. The shaft is attached to the pressure vessel so that when the motor is actuated, the pressure vessel can be rotated in a desired revolutions per minute. The method includes placing a mixture in the pressure vessel and then attaching the caps to the upper and lower ends of the vessel. The upper cap has a pressure gauge and has a pressure inlet and a pressure relief valve. The circular disk is placed in the vessel. The vessel is pressurized to a desired pressure with a gas motor. The motor is then actuated to rotate the vessel. As the vessel rotates, the circular disk is caused to move through the mixture, which will contain at least water, cement and a foaming agent, to disperse the gas through the fluid. The rotation of the vessel will filly foam the fluid. Tests can then be conducted on the filly foamed fluid. A fluid loss test can be conducted by opening the pressure relief valve to relieve pressure in the vessel and by opening a valve in the bottom cap to allow filtrates to pass out of the vessel. Compression tests can be conducted by curing the mixed sample inside the vessel at a desired temperature for a desired time and thereafter removing the cured sample from the pressure vessel to conduct compressive strength tests.
摘要翻译：一种用于发泡并随后测试发泡流体的方法和装置。该装置包括具有上盖和下盖的圆柱形压力容器。具有多个开口的优选圆形开口的圆盘放置在压力容器中。该装置还包括具有从其延伸的轴的马达。轴连接到压力容器，使得当电动机被致动时，压力容器可以以每分钟所需的转数旋转。该方法包括将混合物放置在压力容器中，然后将盖连接到容器的上端和下端。上盖具有压力表，并具有压力入口和减压阀。将圆盘放置在容器中。用气体马达将容器加压至所需的压力。然后电动机被致动以使容器旋转。当容器旋转时，使圆盘移动通过混合物，其至少包含水，水泥和发泡剂，以将气体分散在流体中。容器的旋转会使流体发泡。然后可以对发泡流体进行试验。可以通过打开压力释放阀以减轻容器中的压力并且通过打开底盖中的阀来允许滤液从容器中流出来进行流体损失试验。压缩试验可以通过将容器内的混合样品在期望温度下固化所需时间，然后从压力容器中除去固化的样品以进行抗压强度试验来进行。
