Abstract
The invention relates to a high-effective, low-toxic and safe oil-base paraffin remover for an oil well, which solves the problem that the paraffin deposits on the oil well in the sagiz oil field in Kazakstan. The technical scheme for solving the problem is that the oil-base paraffin remover is formed by preparing the following components according a certain volume ratio: an organic solvent, a penetrant and a weight additive. The final density of the paraffin remover is 0.825g/cm3, the paraffin dissolving rate is 6.74mg/min, and the paraffin remover does not contain corrosive compounds such as chlorine and sulfur. The pre-treatment process before crude processing is simplified, the severe corrosion on the device is eliminated, simultaneously the components of the oil-base paraffin remover are inexpensive and easy to obtain thus the oil-base paraffin remover has a low cost. The oil-base paraffin remover is an ideal paraffin remover with the characteristics of quick paraffin dissolving rate, safety, reliability and convenience in use, storage and transport process.
Description
Technical field
The present invention is chiefly directed to the paraffin remover of optimizing on the performance; More serious to Kazakhstan's Sagiz oil field wax deposition; Under all unconspicuous situation of application machine paraffin cutting and hot-washing wax remover effect, the present invention can solve the oil well paraffinication problem, and has improved well oil output greatly.
Background technology
The oil field on stream, ubiquity oil well paraffinication phenomenon.Wax deposition makes that oil pumper load increases, pump efficiency reduces, oil well output descends, rate reduces when recovering the oil, even directly blocks oil pipe, causes oil well to stop production.Therefore control and remove of well paraffin is the important technique measure that guarantees the waxy crude oil ordinary production.Present dewaxing method has a variety of,, effect lower to the paraffin removal from oil well cost with chemical agent better, instant effect, be use at present more a kind of.What the present invention is directed to is the paraffin remover in Kazakhstan Sagiz oil field.
Summary of the invention
In order to solve the more serious problem of Kazakhstan's Sagiz oil field wax deposition, the present invention has developed the paraffin remover in a kind of Sagiz of being applicable to oil field.Its technical solution scheme is that this paraffin remover is made up of organic solvent, permeate agent and weighting agent, can prepare completion according to certain ratio respectively.This paraffin remover density is about 0.825g/cm
3, dissolving wax speed is 6.74mg/min.
Embodiment
Elaborate below in conjunction with the practical situation specific embodiments of the invention.
Provide by technique scheme, the present invention in the specific implementation, this paraffin remover is made up of organic solvent, permeate agent and weighting agent, wherein; Organic solvent is a paraffin remover primary solvent part, and the weighting agent dosage is limited density, if according to volume ratio; Promptly measure the benzene series 1 of TV about 29%, the benzene series 2 of TV about 19%, the sherwood oil of TV about 32%; The weighting agent of TV about 20%, the tensio-active agent of TV about 0.1%, gained liquid is paraffin remover of the present invention.
With preparation density 0.825 g/cm
3, 1m
3Paraffin remover is an example, specifically is by 290L benzene, 190L YLENE, and the 320L sherwood oil, 1L surfactant B asosol XP40, the 200L heavy benzol is processed.
Above-mentioned each component, said benzene, YLENE, sherwood oil, heavy benzol are commercially available Shanghai Petrochemical Co. Ltd.'s product; Said surfactant B asosol XP40 is commercially available BASF chemical company product.
This system is the oil type paraffin remover, and the effect of organic solvent-benzene, YLENE and sherwood oil is: organic solvent can be used as the good solvent of oil well wax, can be with oil well because temperature and pressure and the wax of coalescence dissolves fast and more completely;
Influence of surfactant is: tensio-active agent has infiltration and promotes the dispersive effect, when organic solvent during dissolving wax appearance, the adding porous of proper amount of surfactant to wax appearance deep, impel the high density solvent to the diffusion of lower concentration direction, promote wax appearance to dissolve;
The effect of weighting agent heavy benzol is: organic solvent often density is lower, needs to increase the weight of to reach expection density with heavy organic solvent.
Final paraffin remover density 0.825 g/cm of the present invention
3, dissolving wax speed accordingly is 6.74 mg/min, and molten wax speed is fast, and simultaneously, the present invention is sulfur-bearing, chlorine element not, environmental protection, low toxicity, open flash point<40 ℃, in a word, be a kind ofly be applicable to that Kazakhstan Sagiz oil field is efficient, the oil base paraffin remover of low toxicity, safety.
