摘要
RFT (Repeat Formation Tester)是一个非常重要的测试工具.它可以测试不同深度和不同层位的地层压力.在直角坐标纸上绘制的地层压力与深度的关系图,称之为压力梯度图.该图不仅可以用于确定地层流体(气、油或水)的性质和接触面,而且还可以用于识别油气藏的类型.测试层的原始地层压力和有效渗透率,可以利用球形流或柱形流的压力恢复曲线加以计算.
The RFT is a very important testing tool. It may test the reservoir pressures of different depths and layers. The plot of reservoir pressures versus depths on rectangular coordinate paper is known as pressure gradient graph This graph can be not only used to determine the nature and contact of the reservoir fluids but also used to identify reservoir type. The initial reservoir pressure and effective permeability of the layer may be calculated by the pressure buildup curve of spherical flow or cylindrical flow. The solution methods of above-mentioned problems are presented in this paper.
