摘要
Abstract
Due to high cost of unconventional oil/gas ifelds development like tight gas, it is in urgent need to study optimized fast drilling in order to reduce drilling costs. The development of unconventional oil and gas needs to place long horizontal sectionin in the reservoir. In view of the technical challenges like dififculty in control of wellbore trajectory in long horizontal section and low penetra-tion rate, the mechanical properties of bottomhole assembly was analyzed and optimized through computation, and the compound drill-ing rate in the horizontal section was improved, all of which reduced the number of trips in combination with bit selection. The drillstring oscillator was used to improve wob transferring efifciency;oil-based drilling lfuid was specially prepared for horizontal section, which greatly reduced the friction factor and effectively inhibited wellbore instability. The application of optimized fast drilling technology in Daylight Unconventional Oil/Gas Field (Canada) shows that this technology signiifcantly reduces drilling period and drilling costs, and provides useful reference for high-efifcient development of domestic unconventional oil/gas ifelds.关键词
