《世界石油》介绍了以下几条降低井控成本的措施。①不要按预测的最大地面压力来设计井口和防喷器组。因为井筒中始终都有泥浆,泥浆柱的静压将使地面压力降低。对一口按原设计要装10000psi(1Pa=0.145038×10-3psi,下同)井口和防喷器组的井,只须订购一套5000psi的装备就行了。它 World Petroleum introduced the following measures to reduce well control costs. ① Do not design wellhead and BOP stacks according to the predicted maximum surface pressure. Because the mud is always in the wellbore, the static pressure in the mud column will reduce the surface pressure. For a well that is supposed to be equipped with 10,000 psi (1 Pa = 0.145038 × 10 -3 psi) wellhead and BOP stacks as originally designed, just order a 5,000 psi kit. it
