Drilling and completion technology for YYP-3-horizontal well
摘要
Abstract
In order to develop the technology for drilling horizontal wells of continental shale gas in Erdos Basin, Yanchang oilifeld drilled the Well YYP-3 in 2013 which has the large offset distance. By optimizing well conifguration, strengthening the well trajectory control, optimizing the drilling bit and BHA and using the whole oil-based lfuid and lfoat casing running technology, no downhole troubles occurred during drilling and the casing was run in place at one time. The drilling time was 7 days shorter than design;average ROP of the whole well was up to 4.91 m/h and the ROP of horizontal section was up to 13.16 m/h, creating a number records in domestic drilling of shale gas horizontal wells. The actual drilling effect of this well shows that the drilling and completion technologies in this paper can be promoted and used in continental shale gas exploitation, and provide a reference for drilling of horizontal shale gas wells with large offset distance in other part of China.关键词
