A fast assembling and disassembling sleeve blowout preventer was developed,which can satisfy the requirments of sealing mutiple pipes,changing the packers frequently and through-tube and tube clamp.The connection configuration of locking segment and mutiple packers are adopted in the sleeve blowout preventer.Based on finite element analysis method,the sealing properties of packers as well as the effects of oil pressure and packer thickness on contact pressure were analyzed.The results of the test and the application in field show that the developed sleeve blowout preventer has the advantages with small size,fast opening and closing,a little hydraulic flow,fast changing packers,large range of sealing,high security and reliability.
