Abstract

The invention discloses a three-dimensional physical simulation experimental apparatus of a heterogeneous bottom-water reservoir and a saturation determining method thereof. The apparatus comprises a core holder (1), a confining pressure pump (9), a constant-pressure constant-speed displacement valve A (7), a piston container A (23), an oil-gas-water meter B (4), a back pressure device A (5), an oil-gas-water meter A (3), a back pressure device B (6), a constant-temperature tank (2), a constant-pressure constant-speed displacement valve B (8), a piston container B (24), a pressure meter A (19), a pressure meter B (21), a pressure meter C (20) and a pressure meter D (22). The apparatus is suitable for planar and vertical heterogeneous displacement experimental researches, research on influence of edge-bottom water upon displacement, and real-time analysis on oil (gas) and water saturation distribution.

Description

technical field [0001] The invention relates to a three-dimensional physical simulation experiment device and a saturation determination method of heterogeneous bottom water oil and gas reservoirs. Background technique [0002] In heterogeneous oil (gas) reservoirs, interlayer heterogeneity is the most significant, but plane heterogeneity cannot be ignored. When water flooding is used to exploit this type of reservoir, the effect of water flooding is not ideal, especially when there are edge reservoirs. At bottom water, the situation becomes more complicated. Therefore, for edge-bottom water oil (gas) reservoirs with strong heterogeneity, it is necessary not only to carry out horizontal and vertical heterogeneous displacement experiments, but also to study the influence of edge-bottom water on displacement, and to analyze oil and gas in real time. (Gas) water saturation distribution. At present, there are few well-known flooding experimental studies that comprehensively co...
