当下,油气资源正在以急剧的速度减少,如何进行高效的油气开采成为人们研究的热点课题。控压钻井技术在油气开采中具有广阔的应用空间,它能够降低泥浆漏失、提高钻井时效以及提高水平段的延伸能力。但是当下我国在这项技术的应用上还处于初级阶段。本文对控制压力钻井技术进行了阐述,对其在现场的应用进行了研究。 At present, the resources of oil and gas are decreasing rapidly, and how to carry out efficient oil and gas exploration has become a hot research topic. Controlled-pressure drilling technology has broad application space in oil and gas exploration, it can reduce mud loss, improve drilling time and improve the horizontal section of the extension capacity. However, our country is still in its infancy in the application of this technology. This paper describes the control of pressure drilling technology, its application in the field were studied.
