作者描述了一种自动化工作流程，通过确定最小油管头压力（THP）来帮助缓解因过度压降而导致的出砂。该自动化工作流程旨在自动校准、分析并推荐可行的措施来控制THP，防止出砂。这使得油气作业者能够控制出砂，从而提高产量并减少修井作业。

场地背景

A气田是陆上气田，已投产超过15年。采用底水驱，储层压力未见明显下降。主储层砂体为渐新统至中新统，砂体性质较软，易出砂。

Automated Workflow Mitigates Sand Influx by Determining Minimum Tubinghead Pressure

This paper describes an automated workflow that helps mitigate sanding caused by excessive drawdown by determining the minimum tubinghead pressure.

The authors describe an automated workflow that helps mitigate sanding caused by excessive drawdown by determining the minimum tubinghead pressure (THP). The automated workflow is designed to autocalibrate, analyze, and recommend actionable measures to control THP to prevent sand ingression. This enables oil and gas operators to control sand production, resulting in production enhancement and fewer workover jobs.

Field Background

Field A is an onshore gas field producing for over 15 years. With bottomwater drive, no depletion of reservoir pressure was evident. The main reservoir sand, of Oligocene to Miocene age, is weak in nature and prone to sanding.
