Crude oil automatic handover metering method, device and equipment and readable storage medium

The invention provides a crude oil automatic handover metering method, device and equipment and a readable storage medium. The method comprises the following steps: constructing a first relational expression between the viscosity of the handover crude oil and the density of pure oil, constructing a second relational expression between the temperature of a main pipeline of the handover crude oil and the density of produced water, and constructing a third relational expression among the density of the pure oil, the density of a mixed oil product, the density of the produced water and the moisture content of the handover crude oil; acquiring parameters acquired in real time in a handover process; according to the first relational expression, the second relational expression, the third relational expression and the parameters, real-time pure oil density is obtained through calculation; and according to the real-time pure oil density, calculating to obtain the real-time pure oil weight of the delivered crude oil.
