Product Name:

Principle of Gathered Energy Equi-fluidity Oil Displacement

Product introduction:

This technology can increase the viscosity and decrease the permeability of water phase, enlarge the sweep volume of displacement phase, reduce the viscosity of oil phase, and increase the permeability and facilitate the flow of crude oil.

By optimizing viscosity and matching with heterogeneous oil layer to form multi-viscosity slug, the superposition plunger type movable displacement slug is formed by using the principle of local energy accumulation and diversion of viscosity slug, so as to reduce the water suddenly breakthrough of oil displacement agent along the high permeability area and expand the swept volume. In this way, the injection-production pressure difference is more effectively concentrated on the plunger type moving local displacement segment plug, which greatly increases the displacement energy and enhances the residual oil production capacity.

Accord to the heterogeneous characteristics of an oil lay, a plurality of corresponding displacement agent slugs are adopted, multiple round of injection are matched with oil layers with different permeability - multiple agents, multiple slugs, multiple rounds of equal flow and constant speed synchronous driving, so that the principle of replacing conventional washing by flooding is realized, and the purpose of improving the sweep volume and the oil displacement efficiency is achieved.
