评价储层含油性的热解参数校正方法及其应用

评价储层含油性时，热解参数Ｓ１＋Ｓ２是一项有效参数。其中Ｓ２相对稳定，Ｓ１则随样品类别或露置时间的不同而发生变化。岩心样品的随钻解分析值比较接近真实，岩屑和井壁取心样品的Ｓ１会明显损失。而目前多数探井心进尺少，大多为岩屑录井。

The Correlation Method of Pyrolysis Parameters to Evaluate Hydrocarbon-Bearing Samples from Reservoirs

The pyrolysis parameter of S_1+S_2 is an effective one for evaluating the hydrocarbon-bearing property of reservoir beds. Among which the S,is a relatively stable factor,and the Si could change along with different type of sample and the time with the samples laid in the open.The pyrolysis value along with drilling of a core sample is relatively authentic,and the S_1 of debris or sidewall-sampling sample_s could be lost obviously. At present most exploratory well are less in core boring and more in debris logging.In the condition of a given stratum of a given block,there is a definite linear equation between S_1 and S_2. Such an equation could be set up by the pyrolysis of core sample along with drilling.The S_1 of debris or sidewall-sampling samples is corrected by the equation of the given stratum.The corrected pyrolysis parameter of S_1+S_2 could describe hydrocarbon-besring property of the reservoir bed more objectivdy.
