摘要:
 

深水测试期间，为防止水合物沉积堵塞井筒，需对水合物生成区域进行准确预测。通过实验和理论模型分析，结合现场数据与模拟比较，提出

深水测试复杂组分条件下井筒油气复杂多组分水合物生成区域预测方法，对气体组分、含水率、矿化度等因素进行敏感性分析。模拟结果表明，不同气体组分，对水合

物生成区域影响不同，碳数较大的烃含量越多，水合物生成区域大，是影响水合物生成区域的核心要素；含水率越大，水合物生成区域先增大后减小；矿化度越小，水

合物生成区域越大。研究成果对于深水气井测试管柱内天然气水合物的防治具有一定指导意义。

Abstract:
 

During well testing in deep water, it is necessary to accurately predict the hydrate formation region in order to

prevent hydrate deposition from blocking wellbore. Based on the comparison of field data and simulation result of the analysis of experimental and

theoretical models, a method for predicting the formation area of complex multicomponent hydrate in wellbore under the condition of complex

component testing in deep water was proposed and the sensitivity of influencing factors such as gas composition, water cut and salinity was

analyzed. The simulation results show that different gas components have different effects on hydrate formation area. The more hydrocarbon

content,the larger hydrate formation area is, which is the key factor affecting the hydrate formation area. When the water content increases, the

hydrate formation area increases first and then decreases, and the smaller the salinity, the larger the hydrate formation area is. The research

results have certain guiding significance for the prevention and control of gas hydrate in the test string of deepwater gas wells.
