本文推导了用司钻法及工程师法压井时海上及陆上井控最大套压计算式,式中考虑了井内温度及气体压缩系数的影响,给出了BASIC最大套压计算程序,以便于应用。
In this paper, the calculation formula of maximum casing pressure at sea and onshore well when drilling well with engineer drilling and engineer method is deduced. Taking into account the influence of well temperature and gas compression coefficient, the BASIC maximum casing pressure calculation program is given for application .
