泥浆对储层有效厚度划分影响的实验机理研究

随着钻井技术发展,泥浆性能和泥浆体系也在变化,其侵入地层并形成的侵入带也在发生变化,而这一变化直接影响电阻率测井的测量值。这样,同一地区不同时期钻井测得的曲线会在相同的地层得到不同的数值。如何定性的了解这一影响,并给出适当的归一化方法,以保证整个区块能够采用统一的参数标准来解释油层有效厚度,成为提高储量计算精度的一个亟待解决的问题。

THE EXPERIMENTAL MECHANISM OF MUD EFFECT ON EFFECTIVE THICKNESS DIVISION OF RESERVOIRS

With development of drilling technology,mud property and system are changing.Invasion into the formation and the invaded zones are changing,which influences resistivity logging directly.So the curves measured at different time in the same area vary in the same stratum.Understanding this influence qualitatively and giving out an appropriate normalization method to ensure effective thickness interpretation of oil layers with unified parameters has become an urgent problem in improving the accuracy of reserves...
