Key Technology of Drilling for Yuanye HF-1 Shale Gas Horizontal Well
摘要
Abstract
Yuanye HF-1 is the first shale gas pre-exploration horizontal well in Yuanba block of Northeastern Sichuan. Based on the analysis on the difficult points in engineering geology, the third spud section structure was optimized;rational drilling method, drilling fluid system and drilling process measures are selected to form a set of shale gas horizontal well drilling technical scheme suitable for this area.The well is drilled to the objective layer with drilled depth of 4982m, hori-zontal displacement of 1421.73mm, drilling cycle of 168.88d, average penetration rate of 3.07m/h and the three open well diameter enlargement ratio is only 4.82%.关键词
