Shale oil reservoir evaluation method and device

Abstract

The invention belongs to the technical field of shale oil exploitation and particularly relates to a shale oil reservoir evaluation method and device. The method comprises the following steps: firstly, determining paleoclimate of a to-be-detected rock core sample of a to-be-evaluated shale oil reservoir, and then acquiring a favorable development and preservation index, a shale oil enrichment degree index and a brittleness index of the to-be-detected rock core sample so as to determine that the shale oil enrichment degree of the to-be-evaluated shale oil reservoir is an enriched reservoir which is beneficial to shale oil exploitation. According to the method, the shale oil reservoir is evaluated from multiple aspects so as to effectively and accurately determine whether the to-be-evaluatedreservoir is the favorable area for shale oil enrichment and whether the area is favorable for shale oil exploitation, and the selection of the dessert area of the shale oil and the effective exploitation of the shale oil can be effectively guided.

Description

technical field [0001] The invention belongs to the technical field of shale oil exploitation, and in particular relates to a shale oil reservoir evaluation method and device. Background technique [0002] With the continuous consumption of conventional oil and gas resources and the increasing demand for energy from economic development, the position of unconventional oil and gas in the energy structure is becoming increasingly important. One of them is shale oil, which refers to the organic-rich nano oil in the underlying pore-throat shale. [0003] Benefiting from breakthroughs in key development technologies such as horizontal well fracturing, North American shale oil resources have entered the stage of large-scale development, proving that they have huge resource potential. Chinese scholars have done a lot of research on the exploration and development of continental shale oil in recent years. However, in recent years, the exploration specifically targeting shale oil h...

Problems solved by technology

[0005] The present invention provides a method and device for evaluating shale oil reservoirs, which are used to solve the problem of inability to effectively and accurately determine whether the reservoir to be evaluated is a favorable area for shale oil enrichment due to insufficient comprehensive research on the target area in the prior art. Is the area favorable for shale oil exploration?
