录井综合解释评价技术在尼日尔Agadem区块的应用
|
摘要
尼日尔Agadem区块发育多套白垩系和古近系砂岩储集层,该区块构造相对复杂,断块纵横交错,油质类型众多,油水关系十分复杂,仅靠常规测井手段,难以准确地进行油气水层解释评价。为提高该区油气水层解释符合率,以地化录井为基础,建立了油质类型划分方法、储集层油气水识别图谱图板方法,并结合地质录井、气测录井资料实现了对尼日尔Agadem地区储集层流体的录井综合解释评价,解释符合率达到85%,取得了良好的效果。
Multiple sets of Cretaceous and Paleogene sandstone reservoirs are developed in Agadem block,Niger.The structure of this block is relatively complex,the fault blocks are crisscrossed,oily types are numerous,and the relationship between oil and water is very complex.It is difficult to accurately interpret and evaluate oil,gas and water layers by conventional logging methods.In order to improve the interpretation coincidence rate of oil,gas and water layers in this block,based on geochemical logging,the classification method of oily types and icon chart method of identifying oil,gas and water were established.Combined with geological logging and gas logging,mud logging comprehensive interpretation and evaluation of reservoir fluid in Agadem block of Niger has been realized.The interpretation coincidence rate is up to 85%,and good results are obtained.
