摘要
研究底水油藏油井的临界产量和见水时间等问题时,首先要对水锥的形态有一个正确的认识。从水锥的剖面形态来看,锥体的侧斜面是一条曲线,而不是直线。把锥体的侧斜面描绘成直线,并以此为前提导出的所有公式,都是不尽合理的;以此计算出的相关参数,肯定也不会是很精确的。近年来的许多研究和文献,涉及到了这一基本问题,因此,澄清这一基本问题,是至关重要的。
The study of the critical production and water breakthrough from an oil well in a bottom water reservoir should be based on sound understanding of water coning shape in it first of all.From the shape of water cone sections,the side-inclined planes are curves rather than straight lines.It is unreasonable or inaccurate,if the planes are described to be straight lines and hence all corresponding equations are derived to calculate the related parameters.In recent years,a lot of studies and literatures are involved in this fundamental problem.For this reason,it is of utmost importance to clarify it.
