摘　　要：由于盐膏层塑性蠕变,钻进时易发生井下事故或复杂情况,严重影响了钻井地质目标的实现。要顺利钻穿盐膏层,首先在进行设计时就要考虑盐膏层的特点,科学合理地进行单井设计。详细论述了钻进盐膏层时,所采用的承压堵漏、钻井液转换、扩孔技术,并详细介绍了钻进盐膏层所采取的技术措施、钻井液维护与处理措施和固井技术措施。Plastic creep of gypsum formations tend to bring downhole accidents and troubles, which is harm to realize drilling geological objective. Successfully penetrating through gypsums require accounting for characteristics of gypsum formation at initial design phase, and scientifically and reasonably planning individual well. Techniques employed for drilling gypsums are discussed in detail, including coping with circulation loss at high pressure, drilling fluid transformation, reaming, technical measurements taken while drilling such formation, mud maintenance and preparation, cementing measurements, etc.
