在对控压钻井技术进行研究的过程中,主要将国内和国外的控压钻井技术进行对比,最终对比得出的结论为:控压钻井技术可以有效的解决窄泥浆密度窗口地层、裂缝发育的压力敏感地层钻井出现的“喷漏同层、喷漏同存”等复杂的问题,而且解决效果较为明显。因此,为了更好的运用控压钻井技术,本文将空压钻机技术的概念,应用方法、工艺流程进行相关的分析,并明确控压钻井关键技术,从而以便于日后对控压钻井技术的应用。
In the process of research on the controlled pressure drilling technology, the comparison between the controlled pressure drilling technology at home and abroad is mainly carried out. The final conclusion is that the controlled pressure drilling technology can effectively solve the problem of narrow mud density window formation and development of fractures Pressure sensitive formation of drilling “Spray leakage with the same layer, the same with the leak, ” and other complex issues, and the solution is more obvious. Therefore, in order to make better use of pressure-controlled drilling technology, this paper analyzes the concept, application method and process of Pneumatic Rig technology, and clearly controls the key technologies of pressure-controlled drilling to facilitate the future application of controlled-pressure drilling technology .
