准噶尔盆地呼探1井高温高压超深井试油测试技术
High-temperature,high-pressure&ultra-deep well testing technology used in Well Hutan 1 in tha Junggar Basin
摘要
Abstract
Well Hutan 1 is an ultra-deep well with high pressure and high temperature.To address the challenges posed by complex geological conditions,adverse well conditions,and extreme operational conditions during the well testing process,a risk assessment of the construction was conducted.The well testing operation primarily faces three potential risks:pipe sticking in the well,well safety and well control risk.Innovative measures were taken to mitigate these risks.An integrated pipe string,optimized for perforation and testing,was used to avoid the risk of pipe sticking in the well.On the base of well safety check,sand production prediction and casing pressure control calculation,the maximum casing pressure limit was set,and the production pressure difference was controlled on-site,eliminating well safety risk.Through optimization of surface testing processes,real-time tracking and analysis as well 000 emergency measures,well control risk was effectively controlled.The safe and smooth well testing operation in Well Hutan gained a high-yield industrial flow of oil and gas,with daily gas production of 61×104 m3 and daily oil production of 106 m3,the recorded reservoir pressure reached an impressive 146.07 MPa.The research results provide technical reference for oil testing in high-temperature,high-pressure and ultra-deep wells.关键词
