海外油田连续自动选井计量研究

Continuously and Automatically Selecting Measurement Research for Overseas Oilfield

摘要: 海外油田单井产量高、气油比大，使得国内已成熟使用的站外计量技术不能满足其大规模快速上产的要求。本文针对中东地区社会局势动荡、工业及人力资源依托差等地缘政治特点，对选井系统、计量系统和控制系统分别进行研究优化，提出一种自动化程度高、无人值守的适用于海外油田的连续自动选井计量装置，其主要由自动选井系统、连续计量系统和RTU控制系统组成，具有单井产能计量范围广、自动化程度高、倒井时间短、计量精度高等优点。本连续自动计量系统已在中东地区某油田计量站成功应用，并取得了良好效果，其广泛推广将有助于全面实现未来油田生产的数字化和自动化目标。

Abstract: To meet the requirements of large-scale and fast production, conventional metering technology will fail in the production well with high production and gas-oil ratio in overseas oilfields. In this paper, we research the well selecting system, the metering system and the control system separately, and propose a high degree of automation, unattended, continuously and automatically selecting measurement system, which consists of automatic selecting system, continuous metering system, and Remote Terminal Unit (RTU) control system. This continuously automatic metering system has many advantages, such as wide measurement range, high automation, short inversion time, and high measurement accuracy. It has been successfully applied in an oil field metering station in the Middle East, and has achieved good performance. We expect that its extensive promotion will benefit the digitization and automation of future oilfield production.
