    • A triaxial test cell and pressure balanced piston therefor that includes a housing containing a vessel wherein a test specimen is located, immerged in a confining fluid. The housing includes a passage wherein the piston is installed to slide so as to move an end thereof into the vesel, which passage includes an annular area formed intermediate therealong wherein a collar portion of the piston is fitted. The piston collar portion includes a face whose surface area is equal to the area of the piston end face that travels into the vessel, and the annular area above that collar upper face is connected by an open passage to that vessel. The piston and passage include appropriate ring seals for providing a pressure seal above and below the passage annular area and that annular area is separated by a pressure seal arranged around the piston collar, with the annular area below that collar vented to atmosphere.
    • 一种三轴试验电池及其压力平衡的活塞,其包括一个容纳一个测试样品所在的容器的壳体,浸入一个限制流体中。 壳体包括通道,其中活塞被安装成滑动以便将其端部移动到囊泡中,该通道包括形成在其中间的环形区域,其中安装有活塞的套环部分。 活塞套环部分包括表面积等于活塞端面进入容器的区域的表面,并且该套环上表面上方的环形区域通过开口通道连接到该容器。 活塞和通道包括用于在通道环形区域上方和下方提供压力密封的适当的环形密封件,并且该环形区域通过布置在活塞套环周围的压力密封件分隔开,而环形区域在该套环下方通向大气。

    • The present invention embodies an improved method for the in situ mining of low to impermeable minerals to sweep out sections of deposits beneath the surface of the earth. Practicing the method of the invention generally involves: locating, by exploration at depth, a mineral deposit suitable for in situ mining and drilling a well bore into that deposit; hydraulically fracturing that well bore utilizing a disintegrating solution to break up aggregate bonding, fully opening the formation, and, at the time of fracturing, by ground surface stress changes determining the principal fracture direction; from the determined fracture direction, locating at least one production well bore appropriately alongside the first well bore and fracturing that production well bore using a disintegrating solution, which solution, optionally, includes proppants therein; passing a leaching solution flow between the well bore and production well bore to dissolve appropriate minerals from the deposit; and drawing out, preferably through the production well bore, the pregnant leaching solution for further refining above ground.
    • 本发明体现了一种用于将低至不渗透矿物原位开采的改进方法,以扫除地球表面下方的沉积物。 实施本发明的方法通常包括:通过深度勘探来定位适于原位采矿和钻井的矿床; 水力压裂孔井利用分解溶液分解骨料粘结,完全打开地层,并在断裂时,通过确定主断裂方向的地面应力变化; 从所确定的断裂方向上,沿着第一井眼适当地定位至少一个生产井眼,并使用崩解溶液破碎该生产井眼,该溶液任选地包括其中的支撑剂; 在井筒和生产井之间通过浸出溶液流,以从沉积物中溶解适当的矿物质; 并优选通过生产井眼抽出怀孕的浸出溶液,以进一步在地面上精炼。

    • A method for accelerating construction of a load bearing ice island, formed by either sea water spraying or flooding techniques, of higher quality or in a shorter time or both than would otherwise be possible. The method involves forced refreezing of spray ice by application of a vertical stream of cold ambient air, as produced by a fan or other devices described, directly downward on the ice surface or by application of the downwardly directed air stream to an impounded mass of sea water. The specific application for the process is construction of improved load bearing structures as used in Arctic regions in support of offshore hydrocarbon exploration and production activities.
    • 一种通过海水喷洒或淹水技术加速承载冰岛的构造的方法,其质量较高或较短时间或两者都比原来可能的要高。 该方法包括通过将由风扇或所描述的其他装置产生的垂直的冷环境空气流直接向下施加在冰表面上或通过将向下指向的空气流施加到被封锁的大海中来强制重新喷射冰 水。 该过程的具体应用是建立在北极地区使用的改进的承载结构,以支持近海碳氢化合物勘探和生产活动。
