FMI成像测井在四川盆地页岩气地层中的应用

Application of FMI imaging logging in shale gas formation of Sichuan basin

由于页岩气在岩性、成藏机制上的独特性,常规油气勘探采用的测井评价方法难以完全适应,因此,针对页岩气地层特点,利用特殊的FMI成像测井技术来识别页岩气储层的岩性,分析地应力状态以及描述储层裂缝。对四川盆地Y页1井进行了FMI成像测井,研究结果验证具有开采价值,为页岩气储层评价、水平井钻进和完井中压裂改造等技术都提供了有力的依据。

Due to the uniqueness of shale gas on the lithology and reservoir forming mechanism,the logging evaluation method used for conventional oil and gas exploration cannot be adapted completely for shale gas.Therefore,according to the characteristics of shale gas formation,special FMI imaging logging technology has been used to identify shale gas reservoir lithology,analyze in-situ stress state and describe reservoir fracture.FMI imaging logging of Shale-1 Y wells in Sichuan basin has carried out and the research results show it is of exploitation value,which provides powerful basis for reservoir evaluation,horizontal well drilling and fracturing technology of shale gas.
