摘要
本文对比了有效井径模型、表皮效应模型及其压降解、样板曲线。结果表明,有效井径模型及其压降解、样板曲线具有相对的优越性和良好的实用价值。同时可以清楚地看到表皮效应模型、压降解的限制,及个别样板曲线存在的问题。文中附有模型简图对比,压降解对比,理论曲线对比,及实例分析对比。
In this paper, a comparison of effective radius model and skin effect model as well as theirs pressure solutions and type curves are made. By the compari- son, it is clear that there are some limitations in effective radius model and its pressure solutions, and some problems in indiyidual type curves. The co- mparison shows that the effective radius model as well as its pressure solution and type curves are better, and have more satisfactory values in practice. At the end of this paper, model sketches, pressure drawdown solutions, theoretical curves and practical example analysis are presented for comparing.
