The long - term solution might instead lie in deep tubewells , which extract water from aquifers 200 meters or farther underground 长远的解决之道可能是深管式井泵，从地下200公尺或更深的含水层抽水。
Abstract : when drilling cluster wells on offshore drilling platform , thefollowing up problem of all kinds of cables and bop controlling cables must be solved 文摘:在海上钻井平台上钻丛式井时，必须解决各种电缆束和防喷器控制管缆的随动问题。
Geologists agree that the risk of arsenic in deep aquifers is low , but before a few million such tubewells are dug , they need to be absolutely sure 地质学家认同较深那一层含砷的风险低，不过，在开凿几百万个深管式井泵之前，这件事必须绝对确认。
Today around 30 percent of bangladesh ' s tubewells are known to yield more than 50 micrograms of arsenic per liter of water , with 5 to 10 percent providing more than six times this amount 目前在孟加拉，已知大约30 %的管式井泵中，每公升水含有超过50微克的砷； 5 ~ 10 %管式井泵的砷含量更是这数字的六倍以上。
Controversy continues to rage , however : chakraborti asserts that some tubewells he measured to be arsenic - free a decade ago are now poisoned , suggesting that complex geochemical processes are even now under way 不过争论仍在持续，加卡波狄声称，某些管式井泵在他10年前测试时是无砷的，现在却有毒，暗示著复杂的地球化学过程直至今日还在继续。
Aim at high pressure high temperature well practice engineering question in field development engineering , especially cnpc southwest oil gas branch gas recovery academy project ' s concretion demand , based upon in existence measuring and testing techniques foundation , the dissertation produce a sort of new optical fiber downhole high pressure high temperature test system , and finish downhole fibre optic pressure sensor ' s design 本文针对油气田开发工程中高温高压井的实际工程问题，特别是cnpc西南油气田分公司采气工程研究院科研项目的具体要求，在分析研究现代测试技术基础上，提出一种新型的光纤式井下高温高压测试系统，并主要完成了井下光纤压力传感器的设计。
