摘要
该文对极高C1、微量重烃与极低C1、高重烃两种极端烃组分油层的录井显示特征进行了分析,并对它们的油藏模式进行了描述,总结气测录井中出极高C1、微量重烃是由生物降解造成的,极低C1、高重烃是由油气在纵、横向上的长距离运移造成的。在气测资料评价油气层遇到困难的情况下,结合分析化验资料综合解释收到了较好效果。
The paper analyzed gas logging showing characteristics in special hydrocarbon composition oil beds of very high C_1 with trace heavy hydrocarbon and very low C_1 with high heavy hydrocarbon, described their reservoir models and summarized that very high C_1 with trace heavy hydrocarbon occurred in gaslogging was caused by biodegradation and very low C_1 with high heavy hydrocarbon was caused by oil-gas long distance longitudinal and horizontal migration. It would get better results by multiple interpretation combining with analysis and laboratory test data when there was trouble during evaluating oil gas beds with gaslogging data.
