摘要
对于松辽盆地中的一些较薄的致密砂岩储层,常规测井曲线,尤其是电阻率测井曲线,因为它们的纵向分辨率较低,往往会降低薄储层含油饱和度的计算精度。为此,探讨了应用“分辨率匹配”方法,将低分辨率的曲线提高为具有较高分辨率的曲线。并利用地层界面处的测井曲线变化率来提取实际的综合响应函数,而不是直接使用测井仪器的响应函数,因此使提高分辨率的处理更符合实际。最后给出了将深浅侧向电阻率测井曲线的分辨率提高到微球形聚焦测井分辨率的应用实例。
Conventional logs, especially resistivity logs of-
ten fail to yield high-precision oil saturation for thin
tight sand reservoirs in Songliao Basin due to the ver-
tical resolution of the logs is relatively low. The pa-
per discusses how to use 'resolution matching'
method to improve the resolution of the logs. In
stead of the response function of logging instrumen-
tation, an integrated response function is derived
from real log curve. An example is given to illustrate
how to enhance the resolution of shallow and deep
laterolog curves to the same level as that of micro-
spherically focused log
