Abstract
The present invention relates to a kind of oil exploitation technology, need to be specially adapted to the exploitation occasion of tool inhibition, breakdown of emulsion and clay stabilization multiple-effect function.
The present invention is formulated under certain temperature, pressure condition with BM-5, alkyl benzyl pyridine, alcohol, hexamethylenetetramine, ammonium chloride, acetic acid and spices.This invention has good acidifying inhibition, breakdown of emulsion and clay stabilization performance, in anti-swollen, the acidizing treatment of oil and water well, can replace expansion-resisting agent, acidification corrosion inhibitor and emulsion splitter simultaneously, has potion multi-purpose characteristics; And low price, production technique is simple, can reduce operating cost greatly.
Description
The present invention relates to a kind of oil exploitation technology, need to be specially adapted to the exploitation occasion of inhibition, breakdown of emulsion and clay stabilization multiple-effect function.
For realizing the normal exploitation of oil gas, anti-swollen, the anti-swollen acidifying technology of water filling is adopted in stable and high yields usually.Owing to a large amount of hydration swelling, dispersion, migrations of using this external working fluid to cause the sensitive clay mineral, the phenomenon of stopping up oil reservoir is of common occurrence, and these external working fluids and formation oil or water effect form the reduction that oil in water emulsion causes zone permeability in addition.Simultaneously, in recovery process, to oil well, when well carries out acidizing treatment, acidizing fluid has serious corrosive nature to the bushing installation of underground oil pipe.Therefore,, often use clay stabilizer,, add emulsion splitter in the working fluid of being everlasting, in acidizing fluid, add inhibiter for preventing oil-water emulsion for suppressing sensitive clay mineral hydration swelling effectively.In the anti-swollen operation of water filling, must add clay stabilizer and emulsion splitter in the treatment solution.In anti-swollen acidizing treatment, must add clay stabilizer simultaneously in the treatment solution, emulsion splitter and inhibiter use simultaneously and bring the compatibleness difference or the problem that is incompatible between medicament owing to various medicaments, fall flat.As No. 4227575, the L55(United States Patent (USP) of the U.S.), the domestic commodity such as PTA, TDC-10, TDC-15 and X12035 that are similar to L55, this class stablizer performance is single, in the anti-swollen and anti-swollen acidizing treatment of water filling, must add emulsion splitter and inhibiter, cause numerous and diverse, the transportation inconvenience of constructing of process operation, improved cost for oil production, generally this class stablizer price is all more expensive.
At the shortcoming that above-mentioned prior art exists, the purpose of this invention is to provide a kind of have simultaneously breakdown of emulsion, corrosion inhibitive function with alkyl
Yl pyridines and BM-5 are the multiple-effect clay stabilizer of main component.
The present invention implements by following technical measures, with alkyl
Yl pyridines
(R, R' are alkyl in the formula, n=1.2) be under 120 ℃ of conditions with BM-5 in normal pressure, temperature, constantly stir, reacted 0.5 hour, adding alcohol then stirred 0.5 hour under normal pressure, 80 ℃ of conditions, adding hexamethylenetetramine then, is to stir 0.5 hour under 40 ℃ of conditions in normal pressure, temperature, adds acetic acid then, under the normal pressure and temperature condition, stir, perfuming stirs under normal pressure, normal temperature condition then, adds chlorination ammonium solution (15% weight concentration) at last and forms this patent product.The part by weight of above-mentioned all raw materials is:
Alkyl
Yl pyridines: BM-5: alcohol: hexamethylenetetramine: NH
4Cl: acetic acid: spices=2: 1: 1: 0.05: 4: 0.12: 0.2.Described BM-5 is tensio-active agent (Binzhou Chemical Plant, Shandong Prov.'s product), and described spices is commercially available hay-scented type spices.
Advantage of the present invention: (one) has good acidifying inhibition, breakdown of emulsion and clay stabilization performance, in anti-swollen, the acidizing treatment of oil and water well, can replace expansion-resisting agent, acidification corrosion inhibitor and emulsion splitter simultaneously, has potion multi-purpose characteristics.(2) the alkyl yl pyridines that is adopted is the cheap material of a class.(3) having good temperature resistance can (＞250 ℃), can be used for steam and annotates to adopt and reduced operating cost.
