摘　　要：岩石热解色谱分析技术是一种新的物理化学分析方法,它以岩心或岩屑为分析对象,通过对样品中烃类的分离与检测,可得到10项分析参数。对于不同含油气性质的储层、不同的流体性质,这些参数也呈现出不同的特征。建立了利用热解色谱特征谱图、特征参数图版等判断储集层含油气性质、划分流体性质的方法。经过多口井的应用表明,该技术对于及时准确地发现新区块新层位的含油气信息,重新评价老井的含油气情况等方面应用效果良好。Pyrolysis chromatography analyzing technique is a new geochemical method in timely and accurately finding the oil and gas bearing information in new formation of new oil block as well as revaluating the former wells. By separating and examining the hydrocarbons in the core or rock fragment samples, it may acquire 10 kinds of parameters which are changeable in different oil and gas bearing formations or when the fluid property changes. With over two years' research and analysis ZPEB Mud Logging Company has established pyrolysis chromatography characteristic chart and parameter plate, etc. for evaluating the oil-gas bearing information and dividing the fluid properties which has been proved effective by being taken into use in several wells.
