Novel sink type oil storage device

The invention discloses a novel sink type oil storage device. The conventional petroleum storage tanks are generally constructed in intertidal zones and are extremely easy to settle along the longitudinal arrangement direction of tank bodies, and the tank bodies can be distorted by differential settlement. The device comprises a storage tank, strengthening walls and strengthening buffer systems, wherein the strengthening walls are uniformly distributed at the periphery of the barrel-shaped storage tank; traction devices are arranged on the tops of the strengthening walls; and the strengthening buffer systems are arranged on the side walls of the strengthening walls and are arranged between the strengthening walls and the storage tank. The device has a simple structure and is convenient touse; an extremely deep foundation is not required to be specially constructed for the storage tank; and the normal use of the whole storage tank cannot be influenced even the foundation is subjected to the differential settlement.
