摘　　要：控压钻井技术由于其类型较多且工作原理、适用范围各不相同,建立一个系统评价标准来衡量控压钻井技术的适用性显得尤为重要。在讨论控压钻井分类及总结各种控压钻井方式优缺点的基础上,给出了微流量控制钻井技术、动态环空压力控制系统、Halliburton控压钻井系统、充气控压钻井技术、加压钻井液帽控压钻井技术、双梯度钻井技术以及连续循环系统等7种控压钻井方式的适用范围,并提出了一套评价方法,为控压钻井适应性研究提供了一种新的思路。There are many types of pressure control drilling technologies and their operating principle and scope of application are different. Therefore, it is very important to establish a system evaluation standard to measure the applicability of pressure control technology. On the basis of discussing the classification of pressure control drilling and the operating principle of several major kinds of pressure control drilling as well as summarizing the strengths and weaknesses of various methods, the scope of application of several major types of pressure control drilling was formulated in this paper. A set of evaluation methods were suggested. A new orientation for research on the suitability of pressure control drilling was provided.
