| 摘 要： | 烃类以微泡、水动力、扩散和渗透方式向地表迁移过程中,其效能、方式与油气藏的盖层、断裂与裂隙系统、储层的流体性质、地层压力等地质因素密切相关.通过对塔里木盆地雅克拉凝析气田上的地表、井中化探资料与地质资料的综合分析,认为该气田的井中垂向地球化学特征、控制烃类垂向微渗漏地质因素、地表化探异常显示之间呈现出很好的内在联系.

| Abstract: | During its migration towards the surface in the forms of microbubble, water power, diffusion and filtration, the effects and styles of hydrocarbon are closely related to such geological factors as the cover of the oil and gas accumulation, fault and fissure system, nature of fluids in the reservoir and pressure of the strata. Based on an integrated analysis of geochemical and geological data from the surface and the boreholes of the Yakela gas condensate field in Tarim basin, the authors hold that there exist fine internal relations between borehole vertical geochemical characteristics of this gas field, geological factors controlling vertical percolation of hydrocarbon and surface geochemical anomalies. |
