介绍了一种HRD钻开液现场配制维护方法和破胶工艺,及其在新疆油田陆9井区的应用效果。通过室内钻开液及其破胶液配方优化与评价,优选出适合陆9井区不下技术套管水平井HRD钻开液及破胶液配方,并成功应用了4口井,钻开液均表现出强抑制防塌、携带、润滑及油气层保护能力,试油日产量较邻井平均值提高了10%以上。
The preparation and maintenance methods and gel breaking technology of HRD drilling fluid on site were introduced, and their application effects in Lu 9 well area of Xinjiang Oilfield were introduced. Through the optimization and evaluation of indoor drilling fluid and its gel-breaking liquid formulation, the HRD drilling liquid and gel breaking solution suitable for no technical casing horizontal well in Lu 9 well area were optimized and 4 wells were drilled successfully It showed a strong inhibition of anti-collapse, portability, lubrication and protection of oil and gas reservoirs. The daily yield of test oil was increased by more than 10% compared with that of adjacent wells.
