考虑不同完井方式的高速非达西效应评价方法
Fast assessment methods for non-Darcy effect of wells completed in different ways
摘要
Abstract
Previous research results show high-speed non-Darcy flow can occur in high-productivity gas wells, high-productivity volatile oil reservoirs and under various other reservoir conditions. Conventional theoretical equations and analytic formulas for high-speed non-Darcy flow are based on open-hole completion without considering the impact of actual completion mode in actual produc-tion. The newly developed productivity equation based on binomial expression takes the impact of perforation completion on drainage area into consideration in deriving high-speed non-Darcy productivity equation. Data from one high-productivity well overseas was used to assess the impact of completion on high-speed non-Darcy effect. The research results show perforation completion may gener-ate higher drainage area when the perforation density is over 25 holes/m. Under such circumstance, high-speed non-Darcy effect is less intensive. In conclusion, the impact of completion mode shall be considered during assessment of high-speed non-Darcy effect in near-well zone of actual producers.关键词
