油砂饱和烃色谱分析表明,天X90块阜三段高密度、高粘度原油早期具有无水洗氧化及生物降解特征,烃源岩长期处于低熟-成熟生烃阶段是其主要成因,油气勘探应围绕次凹生烃中心展开。天X90井阜三段原油成因特殊,低熟不是其唯一成因,应有气洗及二氧化碳洗脱作用的参与,因此该区第三系油气勘探同时,应关注古生界油气及无机二氧化碳气成藏的可能。 相似文献

本文简要介绍了苏北盆地成藏动力学研究方法及成果:(1)提出苏北盆地主要成藏期为始新统三垛组(E2s)沉积期;(2)圈定了三套源岩的成熟排烃范围并追踪了油气运移边界;(3)据初次运移研究,指出苏北盆地有6大油气系统具良好的纵向疏导条件;(4)开展油源、成熟度判别和二次运移研究,划分运聚单元,建立油气运移一成藏模式;(5)分单元、分油气系统清查剩余资源,指出今后勘探的重点领域;(6)应用流体势分析提出今后勘探靶区。 相似文献

A wire-mesh reactor capable of heating samples at a given heating-rate (1—1000 K8226;s-1) was used to investigate the effect of heating-rate on Ca-based absorbent performance of CO2 capture.BET method was used to analyze the morphology of the produced CaO, and the capabilities of the absorbent were compared.It was found that CaO calcined at a higher heating-rate had more appropriate pore distribution for CO2 capture, and the capability of CaO calcined at 1000 K8226;s-1 was 15% higher than that calcined at 1 K8226;s-1 determined by TGA. 相似文献
