Abstract
The invention belongs to liquid manufacturing of fine chemicals and in particular relates to a quick melting and extraction increasing solution capable of quickly melting solidified oil and super-solidified oil in oil fields of Daqing and increasing the crude oil extraction rate. The quick melting and extraction increasing solution comprises the following components in percentage by weight: 5 to 10 percent of dioctyl azelate, 0.2 to 0.5 percent of sodium tripolyphosphate, 2 to 5 percent of maleic anhydride, 0.9 to 3 percent of octadecyl acrylate, 1 to 3 percent of acrylamide and the balance of water. Compared with the existing viscosity reduction technology, the novel technology has the advantages that the quick melting effect is enhanced effectively, and the crude oil extraction rate is increased; and the quick melting and extraction increasing solution is a brand-new safe environmentally-friendly product which is free from danger, pungent smell and corrosion and cannot damage the stratum.
Description
Technical field:
The invention belongs to fine chemicals liquid processed, particularly for the solidifying oil in oil field, super solidifying oil-instant, a kind of novel instant technology of raising oil recovery factor.
Background technology:
Daqing oil field is in the Development and Production process, and every technological processs such as drilling well, oil-gas mining have all adopted a large amount of chemical, mainly contains mineral substance, natural materials, organism, inorganics, macromolecular material etc.Along with the injection of chemical, due to many factors in oil bearing formation property and performance history, on stratum and the layer that colds and heat succeed each other of pit shaft there will be condensing in various degree.Again because in oil reservoir, the depositions such as a large amount of bacterium generations, superpolymer are arranged, the condensing of bituminous matter, colloid, wax, cause that Produced Liquid is moisture constantly to be increased, and causes the producing well oil offtake obviously to descend.So must effectively remove various unfavorable factors, reduce the super solidifying oily set(ting)value of solidifying oil, make its microemulsion-like that is converted into the micromolecular water oil-in, but thereby unrestricted flow improves the output of oil and gas.
Summary of the invention:
Technical problem to be solved by this invention, for the shortcomings and deficiencies in existing common solidifying oily viscosity reduction technology, a kind of solidifying oil-instant liquid is provided, it can not only effectively improve the pour point depression effect, keeps the pour point depression effect time long, improves oil recovery factor, and be without dangerous, non-stimulated smell, corrosion-free, can not injure the safety environment protective product on stratum.
To achieve these goals, the present invention adopts following technical scheme:
A kind of solidifying oil-instant liquid, it is characterized in that being formed by the component of following weight percent: dioctyl azelate 5%-10%, tripoly phosphate sodium STPP 0.2%-0.5%, maleic anhydride 2%-5%, octadecyl acrylate 0.9%-3%, acrylamide 1%-3%, all the other are water.
A kind of solidifying oil-instant liquid mechanism of the present invention is as follows:
Solidifying oil-instant liquid is by dioctyl azelate 5%-10%, tripoly phosphate sodium STPP 0.2%-0.5%, maleic anhydride 2%-5%, octadecyl acrylate 0.9%-3%, and the Multiple components such as acrylamide 1%-3% form.It produces potent friendliness and the dissemination of conversion to the bituminous matter in solidifying oil, colloid, wax.Surround one by one after the link of cutting off between solidifying oily macromole, abolish solid particulate phase absorption, make between solid particulate mutually exclusive.Bring into play simultaneously the performance that it reduces solid-liquid interfacial tension, shale oil, burnt sand oil, solidifying oil, super solidifying oil are all dissolved be converted into small molecules, oil-in-water microemulsion shape, energy unrestricted flow, can be pumped in the lump with Produced Liquid, thereby realize the purpose of energy-saving and production-increase synergy.
Solidifying oil-instant liquid of the present invention and various solidifying oil, super solidifying oil repetition test proof reducing viscosity by emulsifying rate under the low temperature quiescent conditions reaches 98.6%, to compare effect remarkable with other pour point depression product, not only can the super solidifying oil of solidifying oil that oil reservoir and pit shaft produce be dissolved fully, keep the dissolving power time long, after dissolving to stratum without injury, and be without dangerous, non-stimulated smell, corrosion-free, environmental protection, energy-conservation, safe, easy and simple to handle.
Embodiment
Below the present invention will be further described with specific embodiment:
Embodiment 1: the solidifying oil-instant liquid formula of employing is as follows: the component by following weight percent forms:
Dioctyl azelate 10%, tripoly phosphate sodium STPP 0.5%, maleic anhydride 5%, octadecyl acrylate 3%, acrylamide 3%, water 78.5%.
Stir and get final product after the medicament of above-mentioned each component and water are miscible at normal temperatures.
This example formula result of use in oil well, with reference to following table 1:
The result of use of table 1. embodiment 1:
As seen from Table 1, before and after the pour point depression, its day liquid, day oil, back pressure index fairly obvious difference is arranged, extended manufacture cycle 70 days, the 356-22 well increases oily 405t, the 386-26 well increases oily 196t, proves that this formula has good pour point depression effect.
