| 摘 要： | 针对川渝东部地区高陡构造碳酸盐岩地层高压、高产、高含硫天然气井特点，运用井控基本理论，对气井最高允许关井压力、有钻具回压阀情况下如何求取立管压力、气窜速度检测、确定钻井安全作业时间、便捷求取循环压耗和实现正确快速压井作业等几个井控问题，在实践中进行了反复的探索；并对其具体作法作了详细的介绍。

| Abstract: | According to the geological characteristics of carbonate rocks, applying the basic theory of well control, it is explored repeatedly for the 4 issues, i.e. the highest shut-in pressure allowed by gas wells; the standpipe pressure calculation under the conditions of the drilling tool with the check valve; the detection of gas channeling velocity; and the easy calculation of circulating pressure loss. And their concrete operations are introduced in detail. |
