细颗粒地层成井技术在新疆乃至我国北方都一直是钻井工程中的一个难题,要么水进砂亦进,要么阻砂阻水,极大影响了这些地区的地下水开发利用工作。新疆农七师柳沟灌区含水层属细颗料地层,多年钻井始终不能成功,仅1988年至1992年先后钻井24眼,有的井一运行就大量出砂,有的井未受益就报废,给该地区工农业发展造成很大影 Fine-grained formation drilling technology has been a difficult problem in drilling engineering in Xinjiang and even in the north of our country. Either water into the sand or water into the sand or water blocking, greatly affected the development and utilization of groundwater in these areas. Xinjiang Agricultural seven division Liugou irrigated aquifer is a fine grain strata, drilling for many years has always been unsuccessful, only from 1988 to 1992 has drilled 24, and some well run a lot of sand, and some wells did not benefit to scrapped, The development of agriculture and industry in the region caused a great shadow
