Embodiment Construction
[0019]The specific embodiments of the present invention will be further described below in conjunction with the drawings.
[0020]The Chagan Sag is located in the eastern part of the Yingen-Ejinaqi Basin in Inner Mongolia. The discovered crude oil has a large distribution depth span, ranging from 900m to 3000m. The genetic types are complex, including mature light crude oil, biodegradable heavy oil, and some immature- Low-mature heavy oil; the density difference is also large, distributed between 0.8828 and 0.9849 mg / l. Due to the above characteristics, it is very difficult to accurately predict the density of crude oil in this area. The process of predicting the density of crude oil in the reservoir according to the present invention will be described in detail below in conjunction with an example of crude oil density prediction in the Chagan Sag. Such asfigure 1 Shown in this embodiment is the flow chart of using group components to predict reservoir crude oil density. The specific s...
