摘　　要：在海上复杂油气藏中,由于关井时间短,录取资料难以准确反应储层信息和边界问题,针对这一难题,提出反褶积试井技术进行解决。介绍反褶积试井解释技术的的基本原理和适用范围,并对油田实例进行分析。研究表明,反褶积试井技术在具有几开几关的探井、有永久式井下压力计的开发井、没有永久式压力计但有过多次压恢的开发井中具有较好的应用效果。应用结果表明:反褶积试井技术有效解决了复杂油气藏关井时间短、测试资料有限、难以准确获取储层信息的难题,尤其在复杂油气藏中准确识别边界的效果极为显著。反褶积试井技术在复杂油气藏中取得了较好的应用效果,成功解决了实际生产问题,在渤海油田具有较好的应用前景。Since the time of shut-in is short in offshore complex reservoir,acquired data is hard to reflect the reservoir characteristics and boundary condition. deconvolution method is proposed to solve this problem. The basic principle and application scope of deconvolution algorithm for well test is illustrated in detail and field cases have been analyzed. It is shown that the deconvolution algorithm is effective for exploratory wells with several well opening and closing tests,the producing wells which are installed permanent down-hole pressure gauge,and the producing wells performed many times of buildup testing without permanent down-hole pressure gauge. The applied results show that it can successfully solve problems such as short shut-in time,limited testing data to be difficult to obtain accurate reservoir parameters,especially the effect of identifying the boundary of complex oil & gas reservoir is obvious. The deconvolution algorithm technique has gained a better applied result for complex reservoir,successfully solves the practical problems,and has a good application prospects in Bohai oilfield.
