摘要:
重慶黔江頁巖氣區塊山地特征明顯,地表缺水嚴重,淺表地層傾角大、溶洞裂縫發育,常規鉆井面臨井身質量控制困難、惡性井漏頻發、堵漏效果受水源限制成功率低且成本高等難題。為此,將井身結構進行了優化,將靜水位線及以上易漏地層全部納入一開井段,縮減三開制為二開制井身結構,并在一開?444.5 mm 井眼探索應用空氣錘+ 霧化鉆井技術。現場應用表明: 井漏問題得到了有效解決,井身質量控制良好,鉆井周期大幅縮短,節約?244.5 mm 套管約2 000 m。該研究為黔江地區頁巖氣井低成本高效開發探索出一條新途徑。
Abstract:
The Qianjiang Shale Gas Block in Chongqing has obvious mountainous characteristics, serious surface water shortage, large dip angle of shallow strata and well-developed caverns and fractures. In result, conventional drilling is faced with difficulties in wellbore quality control, frequent occurrence of malignant loss of circulation, low success rate and high costs in plugging due to water source limitation. For this reason, the wellbore profile was optimized, the static water level and the leaky strata above it were all included in the first spud section. Three-spud system well profile was reduced to two-spud system well profile and air hammer plus mist drilling technology was explored and applied in the first spud wellbore of ?444.5 mm. Field application shows that lost circulation has been effectively eliminated, the well bore quality has been controlled very well, the drilling cycle is greatly shortened, and more than 2 000 meters of casing of ?244.5 mm is saved. This research has explored a new way for low cost and efficient development of shale gas wells in Qianjiang area.
