摘要
随着国内油气藏勘探开发的不断深入,高含硫油气藏的安全钻井问题日益突出。气侵是含硫气井钻进过程中最常发生的现象之一,与钻井安全息息相关。从含硫天然气井钻井过程中气体侵入方式入手,将气侵方式进行分类,分别探讨了各种侵入的机理、发生工况及其相互联系,并提出直接侵入方式下含硫天然气侵从定性研究到定量化研究的思路和方法,指出了该领域研究的重点和难点,为早日实现现场施工中气侵量的预测及采取相应的井控措施提供了依据。
With the advancement of carbonate reservoir exploration and development in China, the issue of safety drilling in highsulfur carbonate reservoir has attracted more and more attention. Gas cut is one of the most common phenomena in drilling sour naturalgas wells, and it is closely related to safety drilling. Beginning from the modes of gas cut during the process of drilling sour natural gaswells, this paper classifies the modes and discusses the principle, the occurrence condition and interrelation of each mode. And then, theresearch thinking and methods of direct gas cut from qualitative study to quantitative study are proposed, the focus and difficulties inthe research in the field are pointed out, so as to provide theoretical basis for forecasting of the amount of gas cut and taking appropriatewell-control measures.
