摘要
油田钻井作业中排放的废弃钻井液,能在长时间保持液态,对环境保护、油田建设及人畜的安全都不利。本文通过对国内外废弃钻井液处理方法的调研,结合新疆油田情况确定了对废弃钻井液固化处理的方案。针对新疆油田常用的聚磺、钾钙基和聚磺混油三种体系的废弃钻井液,确定了不同固化时间与固化体强度的废弃钻井液固化处理配方。并在新疆油田八区进行了四口井次废弃钻井液的固化处理,达到了预期的效果。
Methods of waste drilling fluid treatment in oilfield and abroad are studied because of the effect of waste drilling fluids on the environment.Waste drilling fluid treatment technology and its future development are discussed in several aspects,such as solidifying technique of abandoned drilling fluids in Xinjiang oilfield.
