摘要
火山岩储层发育特性不仅与岩性特征、岩相分布有关,而且与喷发间歇面溶蚀作用强度和构造裂缝发育程度有关。通过分析三塘湖盆地牛东地区火山岩储层发育特性,明确了形成优质火山岩储层的主控因素,并总结出不同因素下的测井响应特征。最后,依据储层的分布规律,分别建立了不同构造部位的测井解释标准,使得后期调整井的测井解释符合率明显提高。
The development of volcanic reservoirs was not only related with the lithologic features,rock facies distribution,but also with intensity degree of the chemical erosion in eruptive intermission surface and development degree of the tectonic fissures.By analyzing the characters of volcanic reservoir growth in Santanghu Basin of Niudong Area,the major control factors on volcanic reservoir formation were identified,and the logging response characters were summed up.Based on reservoir distribution rules,logging interpreting criteria for different structural locations are established,by which the logging interpreting coincidence rate is obviously improved in adjustment wells at the late stage.
