Problems solved by technology

[0003] At present, the saturation probe method has been widely used in homogeneous models, but it is rarely used in large-scale heterogeneous models. The difficulties in using well pattern models to simulate water flooding effects in heterogeneous reservoirs are as follows: 1 1. It is difficult to ensure the similarity between the simulated reservoir and the real heterogeneous reservoir. The contact relationship between the real heterogeneous reservoir should not be a simple superposition, but should be tight and integrated; 2. For the oil-water reservoir inside the model It is difficult to monitor and describe the distribution and water flooding effect; 3. It is difficult to adjust the wellhead pressure of the well pattern model; 4. The reusability of the heterogeneous reservoir model is low

Embodiment Construction

[0031] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0032] The probe method well pattern model water flooding effect measuring device provided by the present invention is as follows: figure 1 As shown, the device includes a liquid supply mechanism, a reservoir model mechanism, a supporting turning mechanism and a measuring mechanism.

[0033] The reservoir model mechanism includes a flat flat box 1, 147 probe sets 2, injection pipeline and discharge pipeline system.

[0034] The flat case 1 is a square case, and the flat case includes a casing and a case cover, and the case cover and the casing are connected by bolts. By setting a detachable box cover, the box cover can be disassembled to facilitate cleaning of the box body. The flat box has good sealing performance, and the whole body of the flat box is covered with insulating paint, so the insulation effect is good. The lid and the bottom of the casing are respec...

Abstract

The invention discloses a probe method well pattern model water flooding effect measurement device, comprising a liquid supply mechanism, a reservoir model mechanism and a measurement mechanism, the reservoir model mechanism is a component for simulating heterogeneous reservoirs, and the liquid supply mechanism In order to provide components for injecting required liquid into the reservoir simulated by the reservoir model mechanism, the measuring mechanism is a component for measuring the oil-water saturation of the reservoir simulated by the reservoir model mechanism. The device has a simple structure, and can study the water flooding effect of heterogeneous reservoirs and the ultimate recovery of reservoirs under different injection-production conditions by simulating five-point well pattern and reverse five-point well pattern system.

Description

technical field [0001] The invention belongs to the technical field of water flooding effect research in heterogeneous reservoir development of oil and gas reservoirs, and specifically relates to a probe method well pattern model water flooding effect measuring device, which is suitable for simulating the water flooding effect experiment of heterogeneous reservoirs, and is suitable for The recovery factor of heterogeneous reservoirs under different injection-production conditions was studied using the five-point method (reverse five-point method) well pattern. Background technique [0002] During the development of oil and gas reservoirs, due to the influence of reservoir heterogeneity (such as permeability), there must be some differences in the water flooding effect of different production layers. At the same time, the pressure control of production wells and injection wells also affects the oil wells. Productivity, only by correctly understanding the laws of oil-water mig...
