Abstract
To achieve the objective of"higher yields with fewer wells"in efficient exploration and development of shallow-thin-layer reservoirs in Bamianhe Oilfield,the fishbone-like multilateral horizontal well drilling technology has been introduced.A feasibility study was conducted for implementing multilateral horizontal wells technology in these reservoirs.The application of near-bit geosteering tools enabled precise horizontal trajectory control within thin reservoir layers.Wellpath design and optimization ensured accurate well landing and controlled sidetracking,avoiding thin-layer penetration.An optimized drilling model was established,and open-hole sidetracking and horizontal section operations were successfully implemented by adjusting bottom-hole assembly(BHA)configurations and hydraulic parameters.Through multiparameter strata correlation analysis and accumulated technical expertise,real-time layer exit warnings,trajectory deviation prevention during reaming,and inclination control mechanisms were achieved.Since 2024,these innovations have resulted in 100%success rate in first-attempt sidetracking,32.21%reduction in drilling duration compared to design,99%average reservoir penetration rate,and over 80%productivity increase compared to single horizontal wells.This study establishes a standardized workflow for multilateral wells in Bamianhe Oilfield and provides valuable references for efficient development of shallow reservoirs in other oil regions.关键词
