Embodiment Construction

[0073] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be described in further detail below in conjunction with the embodiments and accompanying drawings. Here, the exemplary embodiments and descriptions of the present invention are used to explain the present invention, but not to limit the present invention.

[0074] In this example, a shale oil resource evaluation method is provided, such as figure 1 shown, including the following steps:

[0075] Step 101: Obtain the geological data of each area to be evaluated in the research area, wherein the geological data include: organic carbon weight percentage, hydrocarbon production rate curve of the research area, shale density, organic carbon density, thermal evolution degree of organic matter , shale thickness, shale fracture porosity, shale pores and fractures oil saturation, shale oil density and shale oil volume factor;

[0076] Step 102: Find the h...

Abstract

The invention provides a shale oil resource evaluating method and device. The method comprises the steps that geological data of each region to be evaluated in a research region are obtained; a hydrocarbon production rate curve of the research region is searched for the hydrocarbon production rate corresponding to the organic matter thermal evolution degree of each region to be evaluated; the original organic carbon weight percentage composition of each region to be evaluated is calculated; the maximum organic matter porosity of each region to be evaluated is calculated; the ground organic matter porosity of each region to be evaluated is calculated; the shale oil resource abundance of each region to be evaluated is calculated; according to the area and the shale oil resource abundance of each region to be evaluated in the research region, the shale oil resource quantity of the research region is obtained through calculation. According to the shale oil resource evaluating method and device, the problem that when shale oil is evaluated in the prior art, only organic matter porosity is considered, factors such as non-movable oil are not removed, and therefore the determined shale oil resource quantity is inaccurate is solved, and the evaluating result accuracy is improved.

Description

technical field [0001] The invention relates to the technical field of unconventional oil and gas resource evaluation and unconventional oil and gas exploration, in particular to a shale oil resource evaluation method and device. Background technique [0002] While technological innovation triggered the "shale gas revolution", it also promoted the development of shale oil exploration and research. The evaluation of shale oil resources has also become the focus and difficulty in the process of shale oil exploration and development. Shale oil includes two meanings, broad sense and narrow sense. In the broad sense, shale oil refers to liquid hydrocarbons that occur in mud shale and its interlayers or in nearby tight reservoirs. It is sometimes called tight oil. In the narrow sense Shale oil refers to liquid hydrocarbons that exist in organic-rich mud shale. The shale oil resources mentioned in this article refer to shale oil resources in a narrow sense, that is, specifically r...
