完整的论文概述了数值速率瞬态分析 (RTA) 对干气井的重要性。作者写道,所提出的简单、完全穿透的平面裂缝模型是一种有用的数值对称元素模型,为本文的工作提供了基础。完整的论文使用了合成和现场示​​例来说明数值模拟在执行严格 RTA 中的应用。

介绍

已广泛研究了用于校正叠加和多相流效应的 RTA 方法。通过分析(在此上下文中,“分析”是指偏微分方程的线性化)同时校正叠加和多相流的综合效应是不可能的,因为需要知道饱和度和压力/体积/温度 (PVT) 属性作为所有时间的空间函数。

The complete paper outlines the importance of numerical rate transient analysis (RTA) for dry gas wells. The authors write that the simple, fully penetrating planar fracture model proposed is a useful numerical symmetry element model that provides the basis for the work presented. Synthetic and field examples are used in the complete paper to illustrate the application of numerical simulation to perform rigorous RTA.

Introduction

RTA methods to correct for superposition and multiphase flow effects have been studied extensively. Analytically (In this context, “analytical” refers to linearization of partial differential equations) correcting for the combined effect of both superposition and multiphase flow at the same time is not possible because one needs to know saturations and pressure/volume/temperature (PVT) properties as a function of space for all times.
