Abstract
The invention relates to a heavy oil storage stability test method and heavy oil storage stability test equipment. An oil storage pipe column for simulating storage and transportation conditions of heavy oil transported by an ultralarge tanker is designed; the test oil storage pipe column is 10 to 50 meters in height, is set into one or more sections, and realizes simulation of the oil layer height when various tankers are fully loaded; the test pipe column realizes constant temperature storage of the heavy oil and realizes temperature regulation and control; the temperature range is from 10 to 120 DEG C; the liquid surface of the test pipe column is sealed and stored by inert gas; each section of the test pipe column is provided with a sampling port; sampling analysis is performed at different positions and different time; the stability of the modified oil is judged according to viscosity and spot test data; and the long-term storage stability of the heavy oil is measured by adjusting the storage condition of the heavy oil and testing the stability parameters of the heavy oil with different heights. By the method and the equipment, the storage and transportation conditions of heavy oil transported by the ultralarge tanker are simulated; sampling analysis is performed according to different storage time; the oil storage stability is judged by the viscosity and spot test data; and transportation, storage and processing of the oil product can be guided.
Description
Technical field
The invention belongs to the property testing method of petroleum hydrocarbon, specifically, is the storage stability test method and apparatus of heavy oil, secondary processing oil.
Background technology
At present, in the about 10,000,000,000,000 barrels of residual petroleum resources in the whole world, more than 70% the heavy oil resource.And in China, land heavy oil, pitch resource account for more than 20% of petroleum resources total amount.Oil-sand estimates that the geological resource amount surpasses 6,000,000,000 tons, can adopt stock number above 3,000,000,000 tons.Resinous shale geological resource amount surpasses 47,000,000,000 tons, and technology can be adopted stock number and be surpassed 16,000,000,000 tons, and recyclable amount is above 12,000,000,000 tons.The exploitation ratio of non-conventional oil (as various viscous crude, oil sands bitumen etc.) will increase gradually, and will become China's important strategic and take over one of resource.The huge breach of China's energy will mainly rely on unconventional energy resource such as viscous crude and oil-sand, pitch to remedy.The viscosity height of extra heavy oil and super viscous crude, density is big, do not flow or be difficult under the normal temperature and flow, can not satisfy the requirement of the defeated and ocean shipping of oil pipe, although the heavy oil viscosity behind the upgrading has lowered, but bituminous matter easily precipitates to separate out and causes layering, and heavy oil can cause the security incident of transportation after the layering in transportation.Meanwhile the sulfur content of heavy oil, tenor, acid content and nitrogen content are also higher, can cause the material corrosion of means of transport, also can cause the transportation safety problem, are badly in need of setting up the tubing string storage stability test method and apparatus that can simulate mammoth tanker.Tubing string storage stability test method and apparatus does not appear in the newspapers and patent protection at present.
Summary of the invention
The objective of the invention is to propose a kind of tubing string storage stability test method and apparatus, the oil storage tubing string of design simulation ultra large crude carrier transportation heavy oil accumulating condition.With the oil sample oil storage tubing string of packing into, store greater than test in 90 days, the control storage temperature is measured viscosity, the spot test data of oil sample different time and position at 10-120 ℃, judges the stability of oil in reserve.
A kind of heavy oil of the present invention stores stability testing method, the oil storage tubing string of design simulation ultra large crude carrier transportation heavy oil accumulating condition, and the height 10-50 rice of test string is arranged to one or more snippets, realizes the oil reservoir height of all kinds of oil tanker full loads of simulation; Test string realizes that the constant temperature of heavy oil stores or the realization temperature adjusting, and temperature range is 10～120 ℃; The liquid level of test string is sealed up for safekeeping with inert gas; Every section at test string all is provided with sample tap, adopt diverse location and time sampling analysis,, judge the stability of oil in reserve by viscosity, spot test data, by the different high-rise heavy oil stability parameters of the condition of storage of adjusting oil in reserve, measure the heavy oil extended storage stability with test.
The invention has the advantages that the contrast of the different oil product stability of considering that the employing different process obtains, can establish multitube and store contrast test, consider product carrier arc manipulation spare simultaneously, can set different storage temperatures, the stability of test oil product under physical holding of the stock, traffic condition.
