    摘要:

    井筒完整性治理是保障油气井安全生产的关键问题之一,针对国内尚缺乏自主研发的用于海上油田作业的有效堵漏剂材料,通过对主剂和固化剂体系的优选制备了堵漏剂体系,通过扫描电镜和红外光谱等表征手段结合的方法,研究了堵漏剂的固化机理,通过沉降固化实验测试了体系的模拟环空封堵性能。研究结果表明,所制备的堵漏剂体系兼具低初始黏度(90 mPa·s)和高封堵抗压强度,具有良好的固化性能。通过对堵剂的固化机理分析认为,堵漏剂的高强度固化性能主要是由于强交联反应。封堵模拟测试证实堵漏剂体系具备优异的承压能力(>160 MPa/m),并能够在20 m高度下沉降固化,具有极强的封堵能力。将该堵漏剂体系在南海东部A油田某水平井进行了现场应用,成功完成漏点封堵作业。本研究为井筒完整性治理提供了新型纯液体堵剂,产品具备良好的应用潜力。

    Abstract:

    Wellbore integrity management is one of the key issues to ensure the safe production of oil and gas wells. At present, there is a lack of independent research and development of effective plugging agent materials for offshore oilfield operations. The development of liquid high-strength plugging agent was carried out through the optimization of the main agent and curing agent system. The curing mechanism of the plugging agent was studied by means of scanning electron microscopy and infrared spectroscopy,and the simulated plugging performance was evaluated through the settlement and curing experiments. Th results showed that the developed agent had a low initial viscosity of 90 mPa·s and a high sealing compressive strength,and has good settlement and curing properties,which resulting from the strong cross-linking reaction. it was confirmed that the plugging agent had excellent pressure bearing capacity(>160 MPa/m)and could settle and cure at a height of 20 m,which has a strong plugging ability. The system had been applied to a horizontal well in A oilfield in the east of the South China Sea,and the leak point plugging operation had been successfully completed. This study provides a new pure liquid plugging agent for well integrity management, and the product has good application potential.
