【摘要】：井口控制装置是对石油和天然气井实行压力控制的重要设备,可以对突发事故提前进行预防、检测和控制,是钻井安全的可靠保证。防喷器是井控装置的核心组件,其承压性能的可靠与否直接关系生产设备及人员的安全。对防喷器进行水压力密封试验,是检验防喷器承压性能的最可靠方法。所以在防喷器检测或现场安装后,打开油气层前都需要对防喷器进行压力密封试验。目前,防喷器试压主要依靠气动增压泵、电动增压泵进行增压,这几种增压方式只能满足防喷器试压的基本要求,但都存在着一定的缺陷,不能满足现代井控装置试压在快速高效、准确稳定、自动控制和安全环保等方面的要求。本论文提出的70MPa等级防喷器快速增压装置的研制有效解决了上述问题,在实际应用中取得了较好的效果。该装置体积小、增压迅速、安全系数高、可实现自动化打压及试压控制,辅助集成化的液压系统和上位机软件自动控制系统,大大提高了装置的各种工况的现场适应和应用能力。项目实施以来,先后应用于井控装置试验室试压、现场试压,操作简单方便,工况稳定,可视化程度高,试压检测过程安全高效,取得了一定的安全效益和经济效益。
[Abstract]:The wellhead control device is an important equipment for the pressure control of oil and natural gas wells. It can prevent, detect and control unexpected accidents in advance, and is a reliable guarantee of drilling safety.Blowout preventer is the core component of well control device. The reliability of its pressure bearing performance is directly related to the safety of production equipment and personnel.The test of water pressure seal on BOP is the most reliable method to test the pressure performance of BOP.So it is necessary to test the pressure seal of blowout preventer before opening oil and gas reservoir after BOP detection or field installation.At present, the test pressure of BOP mainly depends on the pneumatic booster pump and the electric booster pump. These turbocharging methods can only meet the basic requirements of BOP test, but they all have some defects.It can not meet the requirements of modern well control equipment in fast, efficient, accurate and stable, automatic control, safety and environmental protection.In this paper, the development of 70MPa grade blowout preventer rapid booster has effectively solved the above problems, and achieved good results in practical application.The device has the advantages of small volume, rapid supercharging, high safety factor, automatic pressure control and pressure test control, and auxiliary integrated hydraulic system and host computer software automatic control system.It greatly improves the field adaptability and application ability of the device under various operating conditions.Since the implementation of the project, it has been successively applied to the well control unit laboratory pressure test, on-site pressure test, simple and convenient operation, stable operating conditions, high visualization, safe and efficient pressure test process, and has obtained certain safety benefits and economic benefits.
