江汉油区废弃井治理应在严格执行《江汉油田石油天然气井井控实施细则》基础上,遵循地层流体不进入井筒、各层位之间不相互窜通、地下水不受污染的原则。废弃井治理可分为前期准备、重建井口、井筒准备、挤堵打塞和治理收尾5个阶段。常规井、套漏井、套损井、落物井以及多种问题并存的复杂井的治理,应根据井况特点,结合油田废弃井的处置要求,采取不同的治理技术措施与封井工艺。在治理过程中要继续坚持方案准备充分、设计评审过关、严格遵照设计施工。
The treatment of abandoned wells in Jianghan Oil Region should follow the principle of Well Control of Oil and Gas Wells in Jianghan Oilfield and follow the principle that formation fluids do not enter the wellbore and the layers do not interflow and groundwater is not polluted. Waste well governance can be divided into pre-preparation, rebuild the wellhead, wellbore preparation, plugging plugging and governance ending five stages. Conventional wells, casing leakage wells, casing damage wells, sediment wells and a variety of issues coexist complex wells governance should be based on the characteristics of the well conditions, combined with the disposal requirements of oil field disposal of abandoned wells, to take different control measures and seal technology. In the process of governance should continue to adhere to the full preparation of the program, design review, in strict accordance with the design and construction.
