Description
Technical field
The present invention relates to a kind of liquid crude drag reducer and preparation method thereof.
Background technology
With the development of world economy, energy demand is growing day by day, and Oil ＆ Gas Storage is the weight for forming energy utilization technology
Want part.In many means of transportation, pipeline transportation have construction speed fast, reduced investment, take up an area less, energy consumption is low, no
Pollute environment, limited the advantages that few by geographical and meteorological condition, and be rapidly developed.At present, what is produced all over the world is exhausted big
Most oil and natural gas pipeline transportations.But pipeline transportation there is also it is serious the shortcomings that, i.e., elastic throughput rate far beyond
Other means of transportation are low.Since during oil exploration, accurate prediction reserves is a very difficult thing, and
Always also there are some uncertain factors for the development prospect in oil field.Even if the reserves in Accurate Determining oil field of having the ability in the future, oil field
Also development period, the phase of abounding with and decline period, and various regions to the demand of oil product also because of expanding economy and the renewal of itself
Regenerate and be varied from, these require that pipeline throughput rate has certain elasticity.In addition, such as pipeline aging causes pressure-resistant performance
Reduce, one of pipeline in parallel occurs that accident needs to overhaul and throughput rate is required for pipeline to have certain tune to throughput rate when also needing to ensure
Energy saving power.The best method to solve the above problems is to use drag reducer.So-called drag reducer, refer to reduce liquid flowing frictional resistance,
Increase the chemical addition agent of throughput rate.It is different using object according to it, the gentle phase drag reduction of water phase drag reducer, oil phase dra can be divided into
Agent.It is known as oil phase dra for the drag reducer in crude oil and its Related product.
Oil phase dra mainly has the function of following several respects：
(1) pipe operations pressure is reduced, improves the safety coefficient of pipeline performance, this is related to national warp in a sense
Ji safety.
(2) if newly-built pipeline considers to use drag reducer in the design process, pipe diameter can be reduced, reduces pump
Scale, so as to greatly save construction investment.
(3) oil product throughput rate can be increased under the conditions of original pipe operations, that is, improves pipe operations efficiency, increase is economical
Benefit.
(4) the more station conveying of oil product can be achieved, close intermediate pump station, save pipe operations cost.
(5) when developing sea, desert, marsh, severe cold areas when the oil field in the severe area of natural conditions, addition can be subtracted
Resist conveying technique is used as conventional, can so increase pumping plant spacing, reduces pumping plant, so that manpower and material resources input are saved,
Increase economic benefit.
(6) quantity for reducing operation pump can be realized in the case where maintaining former throughput rate, not only meets the requirement that pump is safeguarded, but also can
Ensure continuous production.
The drag reducer of traditional poly alpha olefin class is added in oil stream, by distinctive viscoplasticity itself, big point
Subchain is orientated along flow direction natural drawing, this to be orientated the movement for influencing whether fluid particle.The radial effect of fluid particle
Drag reduction agent molecule is set to be distorted, rotational deformation, and drag reduction agent molecule is by the work of intermolecular attractive interaction resistance fluid particle
Firmly, change the action direction and size of fluid particle, make the radial load that flogs a dead horse of a part be converted into following current to axial direction
Power, so as to reduce the consumption of idle work, macroscopically shows the friction loss for reducing fluid, that is, plays the role of drag reduction.
But the drag reducer of this poly alpha olefin class, manufacture craft is considerably complicated, severe reaction conditions, since finished product is
Solid, it is also very cumbersome that scene, which adds technique, and cost is excessively high.
In view of the above circumstances, this problem mainly studies a kind of new liquid crude drag reducer, mainly with deposition theory,
Thin electrolyte film is formed between crude oil macromolecular, on the tube wall of conveyance conduit, flowing crude oil frictional resistance is reduced to reach, mentions conveying capacity
Purpose.Meanwhile the product has good dissolving and cleaning performance to the oil base deposit being deposited on feed-line, so that
Solve the oil flow channel that pipeline deposition produces to reduce, oil pressure rise problem.
