The Study On Annular Plug With Hydraulic Energy

Calculations of annular plug with hydraulic energy is very important to check drill equipment capacity,select,upgrade,transform drill equipment,optimal extended reach well's hole orbit designing in extended reach well drilling.Before research solve this subject qualitatively,this subject starting with hydraulic energy,binding hole collapse,sand bridge,sand settling,big slope well cuttings bed and so on.established calculation model of hydraulic energy needs to cleard annular clogs,and proposed concrete measures of treatments of the above complicated situation,thus find out the methods of annular plug rescission,reached eliminated downhole trouble caused by hole collapse,sand bridge,sand settling,big slope well cuttings bed and so on.According to the mathematical model,the block required hydraulic parameters optimization design program.The case processing annulus through software calculation of two wells wellbore annular plug water energy status is analyzed.
