River-island-type oil reservoir physical model, manufacturing method thereof and experimental method

Abstract

The invention relates to a river-island-type oil reservoir physical model, a manufacturing method thereof and an experimental method. The river-island-type oil reservoir physical model comprises a model body with a plurality of layers of simulation reservoirs, a sealing layer wrapping the model body, a simulation well formed in the top of the model body, and a bottom port formed in the bottom surface of the model body; the model body further comprises non-permeable interlayers located between the simulation reservoirs, the physical property of the non-permeable interlayers is smaller than thatof the simulation reservoirs, and the non-permeable interlayers and the simulation reservoirs both have vertical non-homogeneity; and the model body communicates with the outside through the simulation well and the bottom port. The model can embody the non-homogeneity and the river-island-type configuration characteristics of oil reservoirs, has high credibility, and provides a guarantee for development of the river-island-type oil reservoirs.

Description

technical field [0001] The invention belongs to the field of oil reservoir development research, and in particular relates to a physical model of a channel-type oil reservoir, a manufacturing method and an experimental method thereof. Background technique [0002] Petroleum resources are an important national strategic resource. At present, most oil fields in eastern my country have entered the middle and late stages of development, and the research on oil reservoirs tends to be refined. Among them, the research on remaining oil plays a key role in the stable production of oil fields. Among the oil reservoirs in eastern my country, fluvial reservoirs account for the largest proportion of oil reserves, and channel-type reservoirs are one of the important components of fluvial reservoirs. Therefore, the study of channel-type reservoirs is of great significance. Channel banks are an important feature of braided river deposits. There are layered interlayers distributed inside th...

Problems solved by technology

[0004] In order to solve the problem that the existing physical model of the reservoir cannot fully reflect the characteristics of the channel-type reservoir, which leads to the low reliability of the experimental results, the present invention produces a physical model of the channel-type reservoir, which can reflect the heterogeneity of the reservoir. Qualitative and structural characteristics of channel-type reservoirs with storage layers, high reliability, providing guarantee for the development of channel-type reservoirs
