新疆某地区古地温地质模式与生油期推断
GEOLOGICAL MODEL OF PALEOTEMPERATURE AND CALCULATION OF OIL GENERATION PER旧D!N THE BZ AREA

摘要: 两年前,新疆石油勘探部门在BZ隆起地区约5000米深处钻出了原油。从地质上判断,本区的生油层可能是中、上石炭系。上述事实提出了一个问题,埋藏深度很大的古生界地层产出了原油,本区的古地温状况如何?Abstract: In this paper the paleotemperature in the BZ area of Tarim Basin is studi一ed and its geological model is temperature at lhc end of the made.There was a local thermal alteration at high Paleozoic as a result of a large scale igneous ro-ck intrusion, w hereas the gradients of paleotem peratures of the tum and Cenozoic stratum are lower in this area.Although Mesozoic sira-crude oil from Z一1 well is produced from the lower Carboniferous system, its source rock seems to be middle一upper Carboniferous carbonate distributed in the southern BZ area.The result calculated from TTf value shows that the source roc's Su-tied within 3000-6000 metre deep are still at their main oil一forming stage.
