| 摘 要： | 气体沿井眼体积的变化规律对于溢流检测技术、压井方法和井控措施的及时采取至关重要,为了正确认识气体沿井眼上升体积变化规律,本文在接近钻井实际工况下对气侵进行了模拟,包括单个气泡沿井眼膨胀规律及连续进气时井底压力的变化规律,并取得了初步认识,对今后的安全钻井具有一定的指导意义.

| Abstract: | The variation characteristics of the gas volume along the borehole to kick detection technique,well killing method,and well control method taking are significant.In order to illustrate the gas volume variation characteristics correctly,the gas kick process is simulated under the condition, and is almost the onsite drilling process.The illustration includes the volume expanding of a single bubble and the bottom hole pressure variation during gas invade the borehole continuously.The obtained observation helps... |
