在地面γ能谱资料用于勘查油气田的解释中,作者提出了△∑/σ_∑-△IK/σ_(It)参数的解释方法,并指出了该参数的实质及能降低干扰因素的原因。实践表明,用该参数解释油气田上方地面γ能谱资料收到了明显的地质效果。
In the interpretation of terrestrial γ-ray data for the exploration of oil and gas fields, the author proposes a method to interpret the ΔΣ / σ_Σ-ΔIK / σ_ (It) parameter and points out the essence of the parameter and the reason for reducing the interference factor. Practice shows that using this parameter to interpret the gamma ray spectrum data above the surface of oil and gas fields has received obvious geological effects.
