Embodiment 1

[0030] Embodiment 1, the pressure supplement medium is the water in the reservoir;

[0031]The underground oil depot is located in the reservoir. When the oil is imported, the oil pump on the oil input pipe is turned on, and the oil is filled into the flexible oil storage bag continuously and at constant pressure through the oil input pipe. At the same time, the oil inlet check valve prevents the oil from flowing back. The inner wall of the outer protective bag is under constant pressure. As the volume of the flexible oil storage bag continues to increase and the flexible liquid storage bag is squeezed, the stop valve on the liquid outlet line is opened, and the pressure replenishing medium in the flexible liquid storage bag is released along the liquid outlet line. Squeeze out and discharge into the liquid storage tank, the liquid outlet check valve prevents the discharged water from flowing back into the reservoir, or the liquid discharge check valve prevents the discharged s...

Embodiment 2

[0033] Embodiment 2, based on the first embodiment, the pressure supplement medium can also be seawater in the sea;

[0034] When the oil is input, the oil delivery pump on the oil input pipe is turned on, and the oil is filled into the flexible oil storage bag continuously and at constant pressure through the oil input pipe, and at the same time, the oil inlet check valve prevents the oil from flowing backward. The inner wall of the outer protective bag is under constant pressure. As the volume of the flexible oil storage bag continues to increase and the flexible liquid storage bag is squeezed, the stop valve on the liquid outlet line is opened, and the pressure replenishing medium in the flexible liquid storage bag is released along the liquid outlet line. Squeeze out and discharge into the liquid storage, and the liquid discharge check valve prevents the discharged seawater from flowing back into the sea; the oil product input is completed.

[0035] When the oil product is...

Abstract

The invention discloses an underground oil depot based on a composite material bag body. An outer protection bag with the anti-cutting function is arranged in an underground oil storage cavity, and a flexible oil storage bag and a flexible liquid storage bag which are adjacently arranged in an up-down mode are arranged in the outer protection bag. The underground oil depot utilizes natural caves or manually excavated caves, so that the construction period and labor are greatly saved; the underground oil depot is close to a reservoir or an ocean, so that water supply is sufficient, and drainage is not limited by containing space; natural resources and existing resources are fully utilized, the cost is greatly reduced, and the construction time is shortened; the overground space is saved, the hidden developable space is great, and great significance is achieved for national defense construction; the outer protection bag with the anti-cutting function protects the flexible oil storage bag and the flexible liquid storage bag in a stable internal storage space, and the inner wall of the outer protection bag always keeps uniform pressure, so that the collapse of an underground cave under alternating internal pressure is avoided; and the oil depot is high in utilization value and long in service life and is not affected by the underground water level in use and installation.

Description

technical field [0001] The invention relates to the technical field of underground oil depots, in particular to an underground oil depot based on a composite material capsule. Background technique [0002] At present, there are mainly several ways to store oil in the world, such as underground water-sealed stone cave oil depots and underground salt cavern oil depots. As a way of storing oil, underground water-sealed stone cave oil depots are already very mature in technology. The underground water pressure around the reservoir is always greater than the pressure of the stored oil, and there is a pressure difference so that the oil and gas cannot overflow. The purpose of oil storage has been achieved. In order to generate this pressure difference, the cavern must be kept below the groundwater level forever. And it must slowly flow into the reservoir through the groundwater level, relying on the specific gravity of oil and water to drain the infiltrated water out of the reserv...
