摘要
本文以永乐油田为例，提出了一种适合泥质砂岩储层的有效孔隙度参数解释方法。从油田地质特征入手，通过自然伽马标准层校正建立声波时差、自然伽马相对值及岩心孔隙度三参数复相关关系式，用来计算储层有效孔隙度。与以往二参数建立单相关关系式计算结果对比表明，新方法解释精度明显提高，理论依据也更为充分。
Taking Yongle Oilfield as an example, this paper gives an interpretation method of effective porosity parameters suitable for shale sandstone reservoir. Polycorrelation expression of 3 parameters of interval transit time, natural gamma-ray relative value and core porosity is set up according to oil field geological characteristics to calculate effective porosity of the reservoir. Comparison with the former 2-parameter single-correlation expression shows that the new method has higher interpretation accuracy and more sufficient theoretical basis.
