摘　　要：根据对潜江凹陷新沟咀组５个含油区２５口井１３０块不同含油级别的砂岩储层样品的分析，并结合录井、电测及试油资料进行综合研究，建立了江汉盆地识别评价油层的热解参数标准。应用该标准评价的油层与录井综合解释、电测解释及试油结果对比，符合率都在８０％以上。在新区新带５口探井中随钻采样分析，应用本标准识别的油层，试油结果大都获得１０ｔ／ｄ以上的工业油流，取得明显经济效益。Combined with geological log, electrical logging and testing data, this paper screened out the pyrolysis parameters for identification and evaluation of oil reservoirs in Jianghan basin through the analysis of 130 sandstone reservoir samples having various oil bearing grade from Xingouzui Formation of 25 wells in 5 oil blocks of Qianjiang depression. The oil reservoirs identified by this criterion has an over 80% consistency with that identified by integrated interpretation of geological log,electrical logging, and testing results. In the past two years, the daily oil outputs from the oil reservoirs identified with this criterion at 5 exploratory wells while drilling in new plays are more than 10t, which indicates a good economic effectiveness has been obtained.
