摘要

在河道化系统中进行的一些井压测试,无论是由河流沉积还是断层作用造成的,都不能用常规技术完全解释,因为在石油文献中通常还没有认识到相或储层宽度的变化。在这种情况下,传统上用于单一线性流动的相应方程将提供不准确的结果。因此,必须加以纠正。在本研究中,在石油文献中引入了新的方程,用于常规分析在油藏宽度或渗透率异常作用下形成的线性流动(伪线性)区。该方程没有考虑这两个参数的同时变化。通过综合算例和现场算例验证了所提方程的正确性。

STRAIGHT LINE METHODS FOR ESTIMATING PERMEABILITY OR WIDTH FOR A TWO-ZONE COMPOSITE CHANNELIZED RESERVOIR
Some well pressure tests conducted in channelized systems which result from either fluvial deposition or faulting, cannot be completely interpreted by conventional techniques, since variation in facies or reservoir width are not normally recognized yet in the oil literature. In this case, the corresponding equations traditionally used for single linear flow will provide inaccurate results. Therefore, they must be corrected. In this study, new equations to be used in conventional analysis for the linear flow (pseudo linear) regime formed during the acting of the anomaly - reservoir width or permeability - are introduced to the oil literature. The equations do not consider the simultaneous variation of both parameters. The proposed equations were validated by applying them to synthetic and field examples.
