Description

Novel tertiary sampler of oil tank

Technical Field

The utility model relates to the technical field of oil product sampling equipment, in particular to a novel oil tank tertiary sampler.

Background

In the gathering and transportation production of oil fields, in order to master the crude oil yield of each oil storage tank, a three-level sampler is used for sampling the upper part, the middle part and the lower part of the oil layer of the oil storage tank in sequence according to the regulations, and the crude oil yield of one day is calculated through testing. The current sampler is a cylindrical barrel made of copper materials, a barrel opening is plugged by a soft plug, the sampler is tied by a rope knotted every other meter, the sampler is placed at a required position, and the rope is lifted to open the plug for sampling.

The main problems with such current samplers are:

1. the uncertainty of the tightness of the plug is that the plug is too loose and does not wait for the liquid level at the required position, and the sampler is filled. When the rope is lifted too tightly, the plug needs too long time to open or cannot be opened, so that the one-time sampling success rate and the sampling time are influenced.

2. The sampling barrel is in an open state in the lifting process, the sampler is lifted up again, and the plug is readjusted, so that the representativeness of the sample is influenced.
