高压水清洗深井新工艺及装备的研究开发

阐述了利用高压水清洗深井筛管上的锈垢的旋转喷头及打捞深井井底沉积物的装置，并采用新工艺，既可解决深井清洗的难题，又可使沉淀在深井井底的沉积物被打捞到地面上来．对于超过１００ｍ以上的深井的清洗具有特别重要的意义．

Study on a novel technology and equipment for cleaning the deep well with high pressure water jet

A novel rotating nozzle for cleaning the rusted dirties on the sieve tube in the deep well with high pressure water jet and the equipment for getting out the scale deposition on the ground of deep well are explained.With this novel technology and equipment,not only the difficult problem of cleaning the dirties in deep well can be solved,but also the scale depositions on the ground of deep well upward can be retrieved.This novel technology is possessed of most important significance for cleaning the deep well above 100m.
