摘　　要：原油中最主要的成分是饱和烃,而且饱和烃中最主要的成分是正构烷烃。但是,研究表明,正构烷烃的分布受成熟度的影响很大,同源原油成熟度不同,其饱和烃的分布特征可以有很大差别。生物标志物是原油中相对稳定的烃类组分,它们可以比较细微地反映原油的生源构成、成熟度、成因类型及其后生变化,依据生物标志物的分布来划分原油类型并确定各种原油的来源具有实际意义。The strike-slip structural belt of Dingjiawuzi is right slip fault which is formed by controlling of extensional activity and influencing of slip activity of Tancheng-Lujiang fracture zone.The negative flower structures growed in seismic sections,the echelon arrangement of faults combination in the plane.Slip structural activity of Kongdian formation in DJWZ is recongnized as a 2-stage.Middle and lower of Kongdian formation and upper of Kongdian formation depositional stages.Strike slip movement occurred after depositing in the middle and lower of Kongdian depositional stages.Strike slip movement occurred and depositing simultaneous occurred in the upper of Kongdian depositional stages.Strike-slip faults can not only control the tectonic framework and basin depositional systems,but also can improve the physical properties of the reservoir,become an effective hydrocarbon migration channels,provide an effective oil and gas accumulation traps.
