| 摘 要： | 塔北地区碳酸盐储层地层压力低，钻井中易发生钻井液漏失，对产层造成污染，甚至导致提前完钻，近两年该地区应用了欠平衡压力钻井技术后，较好地解决了上述难题，为增储上产，扩大勘探区域起了积极的作用，本文介绍了欠平衡压力钻井应考虑的问题，钻井参数设计方法以及该技术应用效果。

| Abstract: | The formation pressure is low in Carbonate Reservoir in Tabei Area. It is easy to cause lost circulation when drilling in these areas and damage to pay zone. This problem is solved successfully after the underbalanced drilling (UBD) technique is taken. It is helpful to increase the production rate and expand the exploratory area. This paper introduced the problems which should be considered in UBD, the methods to design the drilling parameter and its application effects. |
