Abstract
The invention provides an oil filling and heating method for oil field single-well tank. To address the problem that all the heat exchanger are arranged at the bottom of the oil tank to cause heat waste and low heating efficiency, the invention determines the oil/water interface of the single-well tank according to the water ratio of the crude oil, and the area of the heat exchangers above the oil/water interface is arranged as follows: the ratio of the area of the heat exchangers above the oil/water interface in the total area of the heat exchangers is equal to 100 percent subtracted water ratio of the crude oil added or subtracted 10 percent. According to the weight of the crude oil, the invention reasonably arranges the area of the heat exchangers, thus capable of fully heating the crude oil and avoiding excessive heat loss in the heating process due to that the temperature is much higher than that of the crude oil; thereby the energy-saving effect is very significant.
Description
Technical field
The present invention relates to heating crude oil method in the oil field individual well tank.
Background technology
The lower limit temperature of former oil freezing point is substantially more than 33 ℃, and therefore the former oil freezing point of the block that has causes must heating before the individual well tank oil transportation throughout the year up to 48 ℃, and jar interior crude oil is warmed up to more than the freezing point, guarantees that crude oil is in liquid state, so that output.Advanced at present mode of heating is that the circulatory mediator heat exchanger is set in single tank, than external heat and the heating of in-built electrical hot pin many advantages are arranged, but the setting of heat exchanger in single tank be science not, at the bottom of just according to the heat rising principle heat exchanger being arranged on jar simply, because each oil well crude oil water content difference, generally between 10-80%, most more than 30%, cause most of heat exchanger to be in the water, a large amount of heat is used to add hot water, crude oil only obtains the small part heat, and water reaches could vaporize more than 80 ℃ heat is delivered on the pasta, all being water before the vaporization, therefore this mode of heating thermal efficiency is low scalding, and has wasted a large amount of energy.
Summary of the invention
The object of the present invention is to provide a kind of energy-conservation, oil field individual well tank oil transportation and heating method that the thermal efficiency is high, to solve the problem that prior art exists.Technical scheme of the present invention is as follows: the circulatory mediator heat transfer tube bundle is set in single tank, it is characterized in that determining according to the moisture content of crude oil the oil-water interfaces of single tank, the area of the above heat exchanger of oil-water interfaces is pressed the following setting that concerns:
The above heat exchange area of oil-water interfaces accounts for ratio=100%-crude oil water content ± 10% of total heat exchanger area.
Under normal conditions, the temperature of water-oil separating is about 20 ℃, China oil field most of the time all is lower than this temperature, therefore, in most cases the heating process of single tank is oil in earlier stage, moisture is from process, later stage is a come-up crude oil melting process, the setting of heat exchanger will take into full account this two needed heats of process, perfect condition is to make water temperature remain on about 20 ℃ after the water-oil separating or make its temperature amplification slower, this method is exactly that the two-part heater area of profit rationally is set, heater area in the oil reservoir increases with the minimizing of crude oil water content, make the increasing degree of water temperature in the heating later stage melting process be lower than the warm increasing degree of oil, avoided the temperature of water to cause heat loss too much far above crude oil temperature in the heating process, this is energy-conservation key.The present invention can based on crude weight heat exchange area rationally is set, therefore can make crude oil obtain enough heats, reach the temperature that needs with the shortest time.With a 20m
3Single tank is an example, 38 ℃ at crude oil water content 60%, freezing point, general oil field, northeast in the winter time jar in crude oil crude oil about 0 ℃, reach 45 ℃ of transport temperatures from 0 ℃, the required heat of heating means was 2.167 * 10 in the past
9Joule, amounting to into electric weight is 602kwh (degree); The required heat of this method is 0.9633 * 10
9Joule, amounting to into electric weight is 292.95kwh, energy-conservationly reaches 51.5%.Single tank was heated oil transportation once in average per 3 days, and 1 year about 120 times, can economize on the use of funds about 180,000 yuan in 1 year, the present invention compared with prior art energy-saving effect is very remarkable, the ten minutes considerable economic of bringing for the oil field.
