海塔盆地饱和烃气相色谱资料解释标准的建立及应用

INTERPRETATION STANDARD FOR GAS CHROMATOGRAPHY DATA OF SATURATED HYDROCARBON AND ITS APPLICATION IN HAILAER-TAMTSAG BASIN

海塔盆地是大庆油田勘探的重点区块，由于饱和烃气相色谱资料的应用还仅局限于色谱图形态特征的直接定性判断，在一定程度上影响了录井综合解释符合率，使得该地区油水层解释的难度较大。通过对原有饱和烃气相色谱资料进行定量化处理，结合试油资料，建立了饱和烃气相色谱定量解释标准，新解释标准在2009年海塔盆地的探井评价井解释中全面推广应用。结果表明：单项资料符合率达到81．8％，录井综合解释符合率由90．0％提升至93．5％，应用效果较好。该解释标准的应用为试油、压裂选层提供了更加详实可靠的数据。

The Hailaer-Tamtsag Basin is the keystone of exploration in Daqing Oilfield, but the interpretation of oil and water layers is still difficult in the area. Because the application of saturated hydrocarbon gas chromatography data is still limited to qualitative morphological judgment, the accordance rate of comprehensive logging interpretation is affected to some extent. A new standard for quantitative interpretation of saturated hydrocarbon gas chromatography data is established through the quantitative processing of existing gas chromatography data of saturated hydrocarbon combined with oil testing data. The new interpretation standard is widely applied to the interpretation of exploratory well and appraisal well in Hailaer-Tamtsag Basin in 2009. The accordance rate of individual data reaches 81.8% , and the accordance rate of comprehensive logging interpretation increases fl＇om 90.0% to 93.5%. The application of the new interpretation standard could provide accurate and reliable data for oil testing and layerselection of fracturing.
