含硫气藏钻采同步交叉作业生产井泄漏风险量化研究
Quantitative Study on the Leakage Risk of Production Wells During Simultaneous Drilling and Production in Sour Gas Reservoirs
摘要
Abstract
Safety issues during the development of sour gas reservoirs remain a critical research priority.Due to geological constraints of mountainous areas,simultaneous drilling and production operations are frequent-ly implemented.However,drilling operations can compromise the integrity of production wells,leading to leak-age and fire accidents.To quantify the leakage risks of production wells during simultaneous drilling and pro-duction operations in sour gas reservoirs,this study investigated a simultaneous drilling and production well pad in the Sichuan-Chongqing region.Numerical simulation methods were used to dynamically simulate the leakage and fire processes of production wells under different influencing factors.The results indicated that the leak ori-fice diameter was a decisive factor for the extent of leakage and fire risks,with risk boundaries undergoing quali-tative shifted as the diameter increases.Furthermore,release pressure served as a critical driving factor for the hazard zone.An increase in this variable exerted a nearly proportional expansion effect on the toxic gas disper-sion range,whereas it leaded to a core intensification of fire thermal radiation.Additionally,reducing the H2 S concentration effectively diminished the risk area associated with H2 S poisoning.These findings provide a theo-retical foundation and practical guidance for the safety management of simultaneous drilling and production oper-ations in sour gas fields.关键词
