摘要
如今利用测井资料进行储层评价已经形成了一套有效的储层识别评价技术。但是利用这套技术对复杂岩 性裂缝型油气藏的流体性质判别仍感力不从心,例如由于岩性和裂缝的影响,地层流体在电性上的反映难以区 分。尤其是青西油田储集层测井响应复杂,利用测井资料判断油水层没有取得很好的效果。为此,本文利用正态 分布法在青西油田较为准确地判断出了相应储层段的流体性质,较好地识别出油水层,在油田应用中取得了较 好的应用效果。
It has been formed a set of effective reservoir-identified techniques to carry out reservoir appreciation by using logging data now, but it still has some difficulty to identify the fluid nature of fractured reservoir in complex lithology by using the set of techniques,for example,it is difficult to identify the reflection of electric property for fluid in stratum because of the influence of lithology and fracture. Especially,the response of logging data is complex in the reservoir of Qingxi oilfield, and it can't achieve good results by using logging data to identify the oil layer and water layer. For that reason, the paper used normal distribution to correctly judge the fluid property in corresponding reservoirs of Qingxi oilfield,better identified oil layer and water layer, which achieved better applied results in oilfield application.
