Abstract:

Aimed at the complicated geological characteristics of fluvial reservoir in Bohai Bay and the limited well logging data in the initial stage of the reservoir development, a method of fluvial reservoir modeling is proposed. Well drilling and logging data combiningwith geological modeling techniques are applied to performthe geological modeling of fluvial reservoir under the impedance constrained inversion. Taking the geologic modeling in BZ3-2 Oilfield in Bohai Bay as an example, the result shows that the quantitative geologic modeling of fluvial reservoir established under the guidance of this method provides a reasonable geology criterion for the exploration of fluvial reservoir and decreases the development risk.

Key words: point bar, meandering river, horizontal well, track design, geological modeling
