摘要： A well cleaning tool includes a surge block, and a jetting tool or nozzle carried by the surge block. The surge block has fluid passageways therein for supplying the jetting nozzle. The surge block is formed of a cylindrical central body with elastomeric disks fixed above and below the central body, the disks being sized to fit relatively snugly within the well casing. The fluid passageway through the central body is threaded at the top for connection of a supply conduit, and may be threaded at the bottom for connection of a jetting nozzle. Thus, the jetting tool can be used for initial cleaning, while the surge block confines the heat and chemical action; then, the surge block can be reciprocated for surging the well. Both surging and jetting can be used simultaneously, and/or alternatively. A plurality of disks can be used as desired, and a jetting nozzle can be outside the disks, or between two disks to confine the chemical action.
摘要翻译：良好的清洁工具包括缓冲块和由缓冲块承载的喷射工具或喷嘴。浪涌块在其中具有用于供应喷射喷嘴的流体通道。缓冲块由圆柱形中心体形成，弹性体盘固定在中心体的上方和下方，盘的尺寸适于相对紧密地配合在井套内。通过中心体的流体通道在顶部被螺纹连接，用于连接供应管道，并且可以在底部处螺纹连接喷嘴。因此，喷射工具可以用于初始清洁，而浪涌块限制了热和化学作用; 那么，浪涌块可以往复运动以使井涌出。和/或喷射也可以同时使用和/或替代地使用。可以根据需要使用多个盘，并且喷射喷嘴可以在盘之外或两个盘之间，以限制化学作用。

摘要： The environment in a porous area, such as in an aquifer in controlled to promote the growth of indigenous microorganisms as well as introduced microorganisms. Nutrients and other growth-promoting chemicals are added to cause the organisms to grow and produce a biofilm that retards fluid movement. Tubes are inserted into the target area, and fluids containing nutrients and other chemical are circulated through the porous area, the paths of circulation defining the areas of growth of microorganisms to produce a barrier, referred to as a biowall. After the biowall has served its purpose, it can be dispersed by injecting chemicals to stop growth and/or to kill the microorganisms.
