一、石油修井作业的特点环境恶劣,地域辽阔,条件艰苦,工程复杂,流动性大,危险性大,多兵种联合作战,装备、设施类型多。上述特点决定了石油修井作业生产过程中事故的复杂性、多变性、突发性和危险性,易发生井喷、中毒、人身伤亡、火灾及爆炸等事故。二、石油修井作业的主要工程石油修井作业的主要工程包括:试油、中途测试、工程测试、小修、射孔、大修、侧钻、封串、压裂、酸化、防砂、堵水、调剖、解堵等。本书主要介绍试油、小修、大修、压裂、酸化等工程。
First, the characteristics of oil well workover Poor environment, vast territory, difficult conditions, complex projects, large liquidity, dangerous, multi-unit joint operations, equipment and facilities types. The above characteristics determine the complexity, variability, suddenness and danger of accidents during the production of oil well workover, and are prone to blowout, poisoning, personal injury and death, fire and explosion accidents. Second, the main work of the oil well workover The main oil well workover projects include: oil testing, midway testing, engineering testing, minor repair, perforating, overhaul, sidetracking, seal string, fracturing, acidification, sand control, Profile control, plugging and so on. This book mainly introduces the test oil, minor repair, overhaul, fracturing, acidification and other projects.
