油藏储层内有机-无机相互作用信息提取与烃源岩精细对比技术研究进展

指出油藏储层中的自生矿物和流体包裹体及其所含的烃类生物标志物,记录了油气藏流体在空间和时间上的非均质性分布特征,是油气流体充注储层过程时所发生的有机-无机相互作用信息的载体;近年来飞速发展的油藏储层固体-流体微区定量分析技术,已经成为储层地球化学和油藏地球化学研究的有效手段,在该领域所取得的研究成果和进展充分证明,运用该项新技术对油藏储层分析所获得的信息,已经远大于对油藏原油定量分析所获得的信息。认为通过油藏储层内烃类组分与烃源岩地球化学特征的分类对比极有可能成为判明我国陆相盆地多源多期复合油藏中不同充注期次烃类来源最有效的解决方案。

ADVANCES IN EXTRACTION OF ORGANIC-INORGANIC INTERACTION INFORMATION WITHIN OIL RESERVOIR AND PRECISE CORRELATION TECHNIQUE WITH SOURCE ROCK

Authigenic minerals and fluid inclusion as well as hydrocarbon biomarkers preserved in these phases could record the temporal and spatial heterogeneity of fluid flow within the oil and gas pool and be the carrier of the information related to the organic-inorganic interaction during oil& gas fluid infilling the reservoir.In recent years,the rapid development of the solid-fluid microanalysis techniques involved in oil & gas reservoirs has been the efficient tools in the field of reservoir geochemistry and oil pool geochemistry.As a result,the achievements obtained in these fields have fully demonstrated that the information extracted by these novel techniques is far more abundant than that obtained from the crude oil within the oil reservoirs.Thus,through the microanalysis on the solid-fluid area in oil pool and correlation with the possible source rocks will be bound to become the most efficient way to expound the origin of superimposed complex oil and gas pools in terrigeneous basins of China.
