完整的论文解决了与井控相关的挑战，并重点介绍了在动态井控模拟平台的帮助下在海上井中成功实施深部瞬态测试 (DTT)。本文旨在提供对作业前模拟过程的见解，从而从良好控制的角度确保更安全的操作。此外，还对 DTT 操作期间的模拟和实际传感器测量结果进行了比较。
DTT 是一种地层测试 (FT) 方法，与传统的层段压力瞬变测试 (IPTT) 相比，该方法允许压力瞬变测试深入地层。DTT 能够测试具有更高渗透率、更大厚度和更低粘度的地层，并实时测量关键参数。在 DTT 期间，地层流体从储层中泵出；泵停止后，地层压力开始恢复，因为远离井眼的流体取代了提取的流体。
The complete paper addresses challenges related to well control and highlights the successful implementation of deep transient tests (DTT) in an offshore well performed with the help of a dynamic well-control simulation platform. The paper aims to provide insights into the prejob simulation process, which ensured a safer operation from a well-control perspective. Additionally, a comparison between simulated and actual sensor measurements during the DTT operation is presented.
DTT is a formation-testing (FT) method that allows pressure transient tests that reach deeper into the formation compared with conventional interval pressure transient tests (IPTT). DTT enables the testing of formations with higher permeability, greater thickness, and lower viscosity and real-time measurement of crucial parameters. During a DTT, formation fluid is pumped from the reservoir; upon stopping the pump, the formation pressure begins to recover as fluid further from the wellbore replaces the extracted fluid.
