| Abstract: | Ram-type blowout preventer is important equipment used in oil drilling operation. Variable bore ram-type blowout preventer, the improved type, is capable of sealing drill tools whose sizes are within a certain range, and has advantages of low cost and convenience. Based on the expatiation of well sealing mechanism, the structural characteristics of several types of variable bore ram are discussed, the operation of variable bore ram is simulated by establishing finite element model, and stress distribution and variation are analyzed, thus providing foundation for design optimization of variable bore ram-type blowout preventer. |
