摘要:
松辽盆地齐家和古龙凹陷青山口组一段页岩油资源丰富.以往主要基于不完整的老岩心资料，以校正后的热解S1或氯仿沥青"A"作为含油性参数计算页岩油资源量，校正参数的准确性受样品新鲜程度、测试手段及校正方法等多种因素影响，导致上述参数的应用存在一定的局限性.根据最新页岩油勘探进展，对比分析了页岩油资源量计算的含油性参数（包括热解S1、氯仿沥青"A"和含油饱和度）的应用差异，认为含油饱和度可反映游离油和溶解烃含量，不用考虑吸附油影响，且无需进行轻烃、重烃和NSO化合物校正，在具有新鲜样品测试数据的条件下，更适合作为研究区页岩油资源量计算的含油性参数.基于最新页岩油参数井钻探成果和测试数据，明确了有效泥页岩厚度、有机质丰度（TOC）、有机质成熟度（Ro）和埋深的平面分布.通过多因素叠合法查明了齐家和古龙凹陷青山口组一段页岩油富集区面积分别为1 957.23 km2和4 509.09 km2.结合密闭冷冻样品的含油饱和度、页岩油密度实测数据和有效孔隙度测井解释数据，通过体积法计算出齐家和古龙凹陷青山口组一段页岩油富集区资源量分别为19.79×108 t和27.29×108 t，表明研究区基质型页岩油具有很好的勘探前景.
Abstract:There are abundant shale oil resources in the first member of Qingshankou Formation in Qijia and Gulong sags of Songliao Basin. In the past, the shale oil resources were calculated mainly based on incomplete old core data with corrected pyrolysis S1 or chloroform asphalt "A" as oil-bearing parameters. The accuracy of corrected parameters was affected by multiple factors including sample freshness, testing means and correction method, leading to certain limitations in the application of the above parameters. According to the latest development in shale oil exploration, the paper compares the applications of different oil-bearing parameters (pyrolysis S1, chloroform bitumen "A" and oil saturation) in shale oil resource calculation. The result shows that oil saturation can reflect the content of free oil and dissolved hydrocarbon, without considering the influence of adsorbed oil and correction of light hydrocarbon, heavy hydrocarbon and NSO compound. This parameter is more suitable for the calculation of shale oil resources under the condition of fresh sample test data. The plane distribution of effective shale thickness, TOC, organic maturity(Ro) and burial depth are determined on the basis of latest drilling results and test data of shale oil parameter well. The shale oil enrichment areas in the first member of Qingshankou Formation in Qijiahe and Gulong sags are 1957.23 km2 and 4509.09 km2 respectively by multifactor overlap method. Combined with the measured data of oil saturation, density and effective porosity logging interpretation data of sealed frozen samples, the resources of shale oil enriched areas in Qijia and Gulong sags are calculated as 19.79×108 t and 27.29×108 t respectively, indicating the matrix shale oil in the study area has a good exploration prospect.
