摘要：

采自塔东北地区英吉苏凹陷华英参1井和维马1井的煤系生油岩模拟实验结果表明:煤在Ro为0.65%之后,液态烃产率急剧增加,1.5%之后,迅速降低,其生油高峰约在Ro为1.0%时,每吨有机碳的最大产烃量约为150kg;碳质泥岩与煤岩具有一定的相似性,但液态烃产率受有机显微组分的影响;灰色泥岩的生排油率很低,以生成天然气为主,当Ro接近2.5%时,产烃量接近200kg.根据煤系烃源岩生排烃模拟实验结果,可以建立演化阶段划分标准,另外,煤岩中显微组分的生烃能力还须进一步研究.

Abstract:

Simulatoin test of coal measure source rock was made with the samples collected from Huaying reference-1 and Weima-1 Wells in Northeast Tarm Basin.The results indicate that when Ro is more than 0.65%,the ratio of liquid hydrocarbon generation increases rapidly;when Ro is greater than 1.5%,the ratio decreased rapidly;when Ro is 1.0% ,the ratio is 150 kg/t.c and this is the peak of oil generation.The carbonaceous mudstone is similar to coal measures.The Hydrocarbon generation and expulsion of grey mudstone is low.When Ro is nearly 2.5%,the ratio is near to 200 kg/t.c.The division criterion of evolution stage could be established according to the simulation results.

Key words: coal measures, hydrocarbon generation and expulsion, hydrocarbon-generating ratio, evolution stage, Tarim Basin
