A test device and method for simulating the principle of oil storage in underground water-sealed oil depot

Abstract

The invention discloses a test device and method simulating oil storage principles of an underground water-sealed oil depot. The test device comprises a water tank, a transparent rock material, a water curtain tunnel, water curtain holes, an oil storage chamber, an oil inlet, an oil outlet and a water drawing port; the water tank surrounds the whole underground surrounding rock environment model made of the transparent rock material, the water curtain tunnel and the inclined water curtain holes connected to the water curtain tunnel are arranged successively from top to bottom in the underground surrounding rock environment model, the oil storage chamber is arranged under a water curtain formed by the inclined water curtain holes, the oil inlet is connected to the internal of the arc-shapedchamber via a pipeline, and the oil outlet is connected with an immersed pump in the upper portion of a bottom water cushion of the arc-shaped chamber via a pipeline to simulate an oil-out process; and the water drawing port is connected with a water pump in a water collecting tank arranged in the bottom of the chamber via the pipeline to control the thickness of the bottom water cushion.

Description

technical field [0001] The invention relates to the technical field of oil storage in underground water-sealed oil depots; it mainly relates to a test device for simulating the principle of oil storage in underground water-sealed oil depots, specifically a test device and test capable of simulating the principle of water-sealed underground oil depots and the effect of oil-water circulation method. Background technique [0002] With the development of society in recent years, oil reserves play a vital role in the development of national security. Underground water-sealed oil depot, as a new type of underground oil storage method, has the advantages of safety, reliability, large oil storage capacity and low environmental pollution. Therefore, the construction of underground water-sealed oil storage caverns is the key implementation object of my country's strategic oil reserves. During the operation of the entire underground water-sealed oil depot, changes in parameters such ...

AI Technical Summary

Problems solved by technology

Nowadays, although my country has made some progress in the actual construction of underground water-sealed oil depots, the changes in various parameters during the operation of the oil depot cannot be accurately monitored. There are also many blind spots in the influence of caverns

[0003] At present, most of the research on underground water-sealed oil depots relies on the construction projects of underground water-sealed oil depots such as Huangdao. However, large-scale underground oil depot projects cannot meet the requirements of some tests, and there is a lack of small-scale simulation test devices for underground oil depots. Accurately simulate the principle of water sealing of underground oil depots and the influence of various parameters, so it is impossible to conduct in-depth research on the various influencing factors of water sealing oil depots
