恢复勘探区油气成藏史对于加快勘探步伐有着至关重要的意义,现有研究方法种类多样并各有其优势与不足,而基于岩芯洗提手段研究油气成藏史的仪器较少。本文阐述了一种新的思路,基于此思路组装的实验仪器能够以与原油充注相反的顺序逐次洗提出岩芯中充注的原油;然后开展后期的地球化学分析,能够更加真实准确地模拟油气成藏史,从而对油气的勘探与开发提供重要信息和依据。
The recovery of the hydrocarbon accumulation history in the exploration area is of crucial significance for accelerating the exploration pace. The existing research methods are diverse and each has its own advantages and disadvantages. However, there are few instruments for studying the hydrocarbon accumulation history based on the core elution method. In this paper, a new idea is presented, in which experimental instruments assembled based on this idea can sequentially elute the crude oil filled in the core in the reverse order of the filling of crude oil, and then carry out later geochemical analysis to simulate more accurately and accurately History of hydrocarbon accumulation, thus providing important information and basis for oil and gas exploration and development.
