Abstract

The invention relates to an oil storage tank liquid level measuring and sampling apparatus for measuring a liquid level of a large oil tank storage tank and acquiring an oil sample in an oil storage tank. The upper part of the oil tank is provided with a sealing cover communicated with an oil tank via an oil tank inlet; a measuring sealing pipe and a sampling sealing pipe are connected with the lower end of the sealing cover; a sampling barrel elevating mechanism and a sampling barrel path-changing operating mechanism are assembled in the measuring sealing pipe; an upper oil measuring cable and an upper suspension rope are bonded to be connected with a sampling barrel and to pass through a spring; one core line of two-phase core lines on the upper end of the cable is connected to an oil surface probe of a floater and the other core line is connected with a water surface probe of the floater; a lower suspension rope works as a positive wire of a universal meter and is bonded with a lower oil measuring cable; the lower end of the lower oil measuring cable is respectively connected with an oil surface measuring insertion hole of a measuring rule mechanism and a water surface measuring insertion hole of the same; the lower end of the lower suspension rope is connected with a measuring intermediate insertion hole of a suspension rope bonding wire of the measuring rule mechanism; and the upper and lower suspension ropes and the upper and lower oil measuring cables are connected to finish measuring and sampling work.

Description

technical field [0001] The invention relates to a tool for measuring and sampling the liquid level in an oil storage tank in the petrochemical industry, in particular to a liquid level measuring and sampling device for an oil storage tank, which is used for measuring the liquid level in a large oil storage tank and extracting the liquid in the oil storage tank. oil sample. Background technique [0002] Petroleum is stored in the stratum in a mixed state of oil and water. At present, water injection is mostly used in oil extraction. During the oil extraction process, a large amount of oil field water must be extracted together with the oil. The oil is extracted from the oil well and stored in the oil storage tank after being separated by the separator. Due to technical limitations, the treatment of the oil by the separator cannot completely separate the oil from water. After the oil is separated by the separator, it will still contain certain water. The oil is deposited in ...
