地化录井烃类恢复系数模拟实验研究

Simulating Experimental Study for Hydrocarbon Recovering Coefficient of Geochemical Logging

该文分析了地化录井烃类损失的原因和影响因素,用模拟实验方法证明现场录井岩屑烃类恢复系数(K)主要受原油性质和岩屑颗粒大小控制,用实验数据拟合出K值计算公式,为方便现场人员资料解释使用,编制了“不同原油性质和不同岩屑颗粒大小烃类恢复系数K值表”。

The paper analyzed the reasons and affecting factors for the hydrocarbon losses of geochemical logging. With stimulating experimental method, the author proved that the hydrocarbon recovering coefficient (K) of wellsite logging cuttings is mainly controlled by oil properties and grain size and fitted out calculating formulae for K value with experimental data. In order to make it easy for the wellsite operator to do information interpretation with it, the author composed“List of Hydrocarbon Recovering Coefficient K Value for Different Crude Properties and Different Cutting Grain Sizes”
