中文摘要：

针对南海油气田存在的非均质油气藏和多相流问题,引入数值试井技术。基于三相试井渗流力学模型、角点网格和网格离散技术建立数值试井体系。针对南海实例油井和气井,应用数值试井技术进行储层、表皮和原始地层压力等参数解释,并与常规方法进行对比分析。结果表明：该技术能很好地解决多相流和非均质等疑难试井问题,为南海复杂油气田的试井分析提供了依据和方向。

英文摘要：

There were heterogeneous reservoir well testing problems, multiphase well testing problems and other problems in South China Sea oil/gas fields. Aiming at the issures, CNOOC Ltd. ZhanJiang imported well testing technology. Numerical testing system was established by using three-phase porous flow model, comer grid technology, grid discretization technology. Through the development and application of numerical testing technology, and a set of effective work processes and working methods was summarized. Numerical well testing was applied in the South China Sea oil/gas fields, a good solution to the multiphase well testing and other difficult issues was obtained, which provided the basis and direction for complex oil field well test analysis in South China Sea
