用一元回归的方法探寻井中岩屑碳酸盐含量与酸解烃含量的关系，发现二者斜率和相关系数在长期稳产油（气）井、干井或产期短油（气）井中特征迥异。长期稳产油（气）井中泥岩的碳酸盐含量与酸解烃含量的斜率和相关系数大于砂岩，而干井或产期短油（气）井中恰好相反，并从碳酸盐矿物形成和不同岩性吸附性能的角度分析了这种特征的形成机理。据此特征提出一种新探井含油气性预测和老井复查的方法，具有快速、低成本的特点，可有效提高探井和老井复查成功率。

Using unary linear regression, the relationship between carbonate content and acidolysis hydrocarbon in a well was investigated, which was different in wells with long production history, dry wells or wells with short production history. The gradient in the mudstone and related coefficient were greater than that in the sandstone in the wells with long production history, but the reverse was true in the dry wells or the wells with short production history. Then the reasons for the characteristics were analyzed from the carbonate mineral formation and the dif?ferent lithology’ s adsorption property. According to the characteristics, a new method was developed for hydro?carbon prediction in exploration wells and the re?examination of old wells. This method was fast and with low cost, and could effectively improve the success rate of new and old wells re?examination.
