反褶积试井在海上短时试井中的应用

Application of Deconvolution Well Testing in Short Time Well Test on Offshore Well

海上油田评价井测试由于受海上气候、钻井船、测试成本高的原因,有效关井测压时间一般比较短,利用常规试井解释方法很难认识油藏边界,限制了在海上油田前期研究中利用有限测试资料对地质条件的认识。现将反褶积试井解释方法成功应用于海上油田评价井短时测试解释中,有效克服因测试时间短而较难认识油藏边界的问题,对海上油田ODP方案研究中的油藏边底水、气顶、断层、储层模式等认识有重要的意义,可指导油藏布井和产能分析。

Due to influenced of well test by the marine climate,drilling ship,high testing costs for interpretation wells,the effective time of shut in pressure survey of offshore oil field evaluation of well test is generally short.So,the reservoir boundary is difficulty to be realized by using conventional well test interpretation method which limits the use of precious test data in the previous study of offshore to understand the geological conditions.The deconvolution interpretation method is successfully used in offshore oil field well test interpretation to overcomes the problem of be more difficult to recognize the reservoir boundary problem for short test time,which has a important sense to study ODP plan of the offshore oil field of edge and bottom water,gas cap reservoir,fault,reservoir model,and guides the oil well deployment and productivity analysis.
