Abstract
The invention relates to a heavy crude viscosity-reducing agent, expecially relates to a oil- soluble heavy crude viscosity-reducing agent. The comprised component and their weight proportion are as follows: (1) solvent oil 50-90%, (2) benzene 5- 15%, (3) heterocycle 5- 10%, (4) diesel 5- 15%, (5) spans -80, 0.5-1.5%. It is characterized in that it can overcome shortcomings in curent viscosity- reducing agent, reduce production cost and release tight condition for domestic energy resource, and the econimical and social benefit is great.
Description
One, technical field:
The present invention relates to a kind of heavy crude thinner, particularly a kind of oil soluble heavy crude thinner.
Two, background technology:
Along with the development and the domestic energy day of China Petroleum are becoming tight, the increasing product of viscous oil recovery amount.Because viscosity of thickened oil is big, flow difficulties, when being difficult to, uses existing conventional crude production technique, must rely on various viscosity reduction technology such as high-temperature steam, viscosity-depression agent effectively to recover the oil, form the corresponding steam stimulation displacement of reservoir oil, the displacement of reservoir oil of medicament viscosity reduction, the displacement of reservoir oil of elasticity gas viscosity reduction or the like the special oil production technology of novel viscous crude.Wherein, medicament viscosity reduction displacement of reservoir oil technology is because the maturation that possesses skills, excellent characteristics such as construction is simple, cost is low, be easy to the special oil production technology common implementing of viscous crude, synergy be obvious and obtain favor at home.
Yet the viscosity-depression agent that domestic existing medicament viscosity reduction displacement of reservoir oil technology is adopted is water-soluble viscosity-depression agent.The defective of such viscosity-depression agent maximum has two: one, and it can only form emulsion with viscous crude, and directly dissolved bitumen matter, colloid only rely on reducing viscosity by emulsifying; The 2nd, be difficult to be distributed in the oil, need the stirring measure as sufficient condition, brought two hang-ups for thus its practical application: the one, oilbearing stratum can't provide agitation condition, the 2nd, low when moisture viscosity reducing effect run counter to desire, have viscosifying action on the contrary.Because domestic most of oil mining initial stage is not moisture or low aqueous well, causes such viscosity-depression agent effectively to use, thereby bring very big difficulty for the initial stage exploitation of viscous crude, restricted viscous crude production to a certain extent.
Three, summary of the invention:
Purpose of the present invention is exactly the above-mentioned defective that exists at prior art, providing a kind of restudies viscosity-depression agent oil reservoir viscosity-reducing mechanism, at actual new viscous crude medicament viscosity reduction theoretical model, the oil soluble heavy crude thinner of the automatic scattering problem of solution viscosity-depression agent net pay zone set up of heavy crude reservoir.
Its technical scheme is: made by following components in weight percentage:
(1) solvent oil, ratio 50%～90%; (2) benzene class, ratio 5%～15%; (3) heterocyclic, ratio 5%～10%; (4) diesel oil, ratio 5%～15%; (5) Arlacel-80, ratio 0.5%～1.5%.
Preferable technical scheme is to be made by following preferable components in weight percentage:
(1) solvent oil, ratio 75%～80%; (2) benzene class, ratio 8%～12%; (3) heterocyclic, ratio 5%～8%; (4) diesel oil, ratio 6%～10%; (5) Arlacel-80, ratio 0.6%～0.8%.
Described benzene class is benzene, toluene, ethylbenzene, to first hexichol, m-xylene, o-Xylol, n-proplbenzene, a p-methyl-ethylbenzene, o-methylethylbenzene, 1.2.4 trimethylbenzene or 1.2.3 trimethylbenzene.
How or the first naphthalene described heterocyclic is penta 2 rare for ring, dicyclo is penta 2 rare, indenes, first indenes.
Described solvent oil is that usual vehicle oil repeatedly refluxes through distillation tower and obtains.
The invention has the beneficial effects as follows: overcome existing viscosity-depression agent defective, can thoroughly solve the production difficult problem of viscous crude initial stage exploitation, create the good technique condition for viscous crude significantly increases production, reduces production costs, alleviate domestic energy shortage situation, economical, societal benefits are remarkable.
