前言 迄今为止,对稳定流承压潜水完整井流量计算的理论公式尚无人简化。本文特给出一个足够准确,运算方便,易于普及的简化公式。简化的思路是:将抽水影响半径(R)这个影响井流量(Q)的次要因素作常量处理,抓住抽水降深(S)这个影响井流量的主要因素,把Q=f(S)曲线(一段弧)近似地用Q=F(S)直线(与所论弧相应的一段弦)代替,以简化计算,并使误差不超出计算所要求的精度范围。为叙述方便起见,本文首先介绍理论公式的推导过程,然后通过数学分析给出简化公式及其误差估计,最后说明简化公式的实际应用。
Foreword So far, no one has simplified the theoretical formula for calculating the total well-flow of a submarine under steady-state pressure. In this paper, we give a simplified formula that is accurate enough, easy to operate and easy to popularize. The simplified idea is to treat the secondary factor affecting the well flow (Q) as a factor of the pumping influence radius (R) as a constant factor, and grasp the main factor that affects the well flow through the drawdown (S). Let Q = f (S) The curve (a segment of arc) is approximately replaced by a straight line of Q = F (S) (a segment of the string corresponding to the arc in question) to simplify the calculation so that the error does not exceed the accuracy range required for the calculation. For the convenience of narration, this article first introduces the derivation process of the theoretical formula, and then gives the simplified formula and its error estimation through mathematical analysis. Finally, it shows the practical application of the simplified formula.
