地层伤害有许多描述方法,但其数学关系不明确,没有统一标准。其基本评价方法是不稳定试井,对普通油层Horner和由线拟合法很方便,但对复杂均质油层尤其非均质油层,前法很少凑效,后者唯一性较差。本文提出表皮系数同其它各种地层伤害参数间的关系通式和统一标准;系统介绍了均质、非均质油层求地层伤害的现代试井程序,包括分析基础、目的、关键和可靠性等人工智能的初步模式。
There are many description methods of formation damage, but its mathematical relationship is not clear and there is no uniform standard. The basic evaluation method is unstable well test. It is very convenient for normal reservoir Horner and line fitting method. However, for complex homogeneous reservoir, especially heterogeneous reservoir, the former method seldom works and the latter one is less unique. In this paper, we present the general formulas and uniform standards for the relationship between the skin coefficient and other damage parameters. The modern well testing procedures for formation damage in homogeneous and heterogeneous reservoirs are introduced systematically, including the basis, purpose, key and reliability The first model of artificial intelligence.
