Abstract

Annular fluid expansion analysis (AFEA) is a vital step when designing an oil/gas well or geothermal well. Traditionally, an AFEA is performed between a drilling operation (initial condition) and a production operation (final condition). However, well design engineers desire to perform an AFEA between any two operations. The objective of this work is to address that challenge. Sequential AFEA refers to the procedure in which output data (e.g., fluid volume change) of one AFEA are used as input data for another AFEA; the underlying operations are “sequential”. As a result, an AFEA can be configured between any two operations, provided that the “initial condition” operation is before the “final condition” operation. This two-pass AFEA model has been implemented in computer programs and has been integrated with a commercial software tool, including a wellbore thermal flow simulator and tubular stress analyzer. Offshore well examples were used to validate the model. Case study results indicate that a sequential AFEA is in good agreement with a traditional one-pass AFEA in terms of both forward and backward operation sequences.
井眼完井设计中的连续环空流体膨胀分析
环空流体膨胀分析(AFEA)是油气井或地热井设计的重要环节。传统上,AFEA是在钻井作业(初始条件)和生产作业(最终条件)之间进行的。然而,井设计工程师希望在任意两个作业之间执行AFEA。这项工作的目标就是应对这一挑战。顺序AFEA是指将一个AFEA的输出数据(例如,流体体积变化)用作另一个AFEA的输入数据的程序;底层操作是“顺序的”。因此,只要“初始条件”操作在“最终条件”操作之前,就可以在任意两个操作之间配置AFEA。该双通道AFEA模型已在计算机程序中实现,并与商业软件工具集成,包括井筒热流模拟器和管状应力分析仪。利用海上油井实例对模型进行了验证。实例分析结果表明,在正向和反向操作顺序方面,顺序AFEA与传统的单次AFEA都有很好的一致性。
