| 摘 要： | 在分析现有水平井流入剖面计算方法的基础上,尝试从纯数学、物理的角度建立简捷的方法,以得出无限导流假设条件下最精确的流入剖面。将远场的影响用积分近似代替,从而化简了无穷累和,并通过平衡法得到了无限导流假设条件下无限大均质等厚水平地层中水平井的流入剖面。新提出的方法回避了各种流动参数,只要已知生产段长度、生产段偏心率、地层厚度和总产能便能求得流入剖面,具有很强的理论性和实用性。与以往的数值模拟方法相比较,该方法简捷准确,而且,该方法可以作为管-渗耦合下流入剖面各种计算方法精度的退化评价标准。

| Abstract: | On the basis of analyzing the current methods for calculating horizontal well inflow distribution, mathematical and physical method was used in order to obtain an accurate inflow distribution under the assumption of infinite conductivity.After the approximate replacement of far-field effect by integral and the simplification of the infinite summation,the distribution of inflow along the production segment in infinite acline was calculated through balancing method under the condition of infinite conductivity... |
