摘要
为解决复杂油气藏油水层识别难的问题 ,在采用多参数判别油水层方面 ,先后出现了灰色理论分析方法、数理统计方法、模糊聚类方法、神经网络方法、微差分析方法 ,这些方法的判别结果大多属于定性和半定量的。采用对应分析的方法 ,能充分地利用测井、录井、试油等方面的信息 ,比其它方法具有较大的实用性。采用该种方法 ,运用DELPHI语言编制的软件 ,对龙西—巴彦查干地区 8口井 2 9层的判别结果 ,经试油证实油水层识别符合率可达到 89 6 %。
In order to solve the problem to discriminate the oil and water formations in the complex reservoir,there have been come into being the method of gray theory analysis,the method of mathematical statistics, the method of fuzzy clustering,the method of neural network,and the method of differential analysis when using multi parameter to discriminate oil and water formation.The discretion result of these methods mostly belong to quality and/or semi quantity.By using the method of correspondent analysis,we can using the information of well logging,borehole log,formation testing and so on fully.In sum,the method of correspondent analysis has more practicability than the others.Using the software about such method programmed in DELPHI,we have gained the discretion result of 8 wells (29 formations)in Longxi and Bayanchagan areas.Compared with the results of testing,the coincident rate can reach to 89 6%.
