Abstract


Casing running technology for extended reach well can control drilling fluid density availably, and clean damage solid phases, and is important for drilling activity. besides an experiment was made for the sake of modifying the theoretical disposal formula. Casing running technology for extended reach well touch upon plenty of the key techniques, thereinto fumula tipping in oil well is one of the key technology.Firstly, analyzing the casing running technology for extended reach well both here and abroad ,along with its in face of bottle-neck technique.Sufficiency analyzing of the size of hole、friction resistance as well as drilling fluid have much effect on the casing running technology for extended reach well. Optimization design of the well track convenient for bushing right tripping in the oil hole.Secondly,through foundation the friction model of the extended reach well casing string, applying antifriction tool minish the friction resistance. the technology of downing bushing under float is advanced bushing technique. Compile coupling force calculating program by VB program language.Thirdly,analyzing the work theory of float bushing, and it is important for downing bushing of the extended reach well.the equal installing position of floatage coupling is computed in theory.Lastly,putting forward betterment design of float coupling,moreover putting forward downing bushing technique of the float is made of the downing bushing. Compile floating coupling force calculating program by VB program language.
