Abstract
A non-ionic clean fracturing fluid taking lecithin as a main agent comprises the following components in percentage by mass: lecithin serving as a main agent, ethyl alcohol and 2-ethyl hexanol. A fracturing fluid system has a good rheological property and high temperature tolerance, contains a small amount of gel breaking liquid residues, and causes little damage to stratum permeability, and the damage rate is below 10%.
Description
Technical field
The invention belongs to technical field of oilfield chemistry, being specifically related to a kind of take Yelkin TTS as the non-ionic type clean fracturing fluid of host.
Background technology
Fracturing liquid is in oil production process, in order to obtain liquid used when high yield utilizes liquid conductive power fracturing fluid layer.Yelkin TTS nonionic agent is that a class can not ionize in water and whole molecule plays the promoting agent of surface-active action, due to their general anti-salt, anticalcium, antiacid, alkali-resistivity is strong, not easily mutually disturb with conventional gravitation free radical again, and little to the permeability injury of reservoir, therefore in fracturing liquid, nonionic agent is used to get more and more.Conventional fracturing fluid system take guar gum as viscosifying agent, and in use often because broken glue is not thorough, breaking glue solution residue content is high; and the permeability injury of formation is larger; usually reach more than 20%, be unfavorable for the protection of hydrocarbon zone, in use more and more limited to.
Summary of the invention
For overcoming above-mentioned the deficiencies in the prior art, the object of this invention is to provide a kind of take Yelkin TTS as the non-ionic type clean fracturing fluid of host, and have and flow change, temperature tolerance preferably, breaking glue solution residue content is low, the feature that the permeability injury of formation is little.
For achieving the above object, technical scheme of the present invention is: a kind of take Yelkin TTS as the non-ionic type clean fracturing fluid of host, by mass percentage, comprises following component:
Host Yelkin TTS 5%-10%;
Acetic acid 0.4%-0.6%;
Ethanol 0.2%-0.4%;
2-Ethylhexyl Alcohol 0.2%-0.4%;
Clear water 89%-94%.
The invention has the beneficial effects as follows:
The present invention can measure with regard to non-ionic type clean fracturing liquid system Progressive symmetric erythrokeratodermia.Connect performance test with non-ionic type clean fracturing fluid to show, when the dosage of Yelkin TTS is 5%, fracturing liquid has and flows change, heat resistance preferably, and leak-off is few, and the injury of formation rate of permeation drops to less than 10%.
This system configurations is easy, and raw material is easy to get, and its fracturing liquid good rheological property, temperature tolerance are strong, and breaking glue solution residue content is low, and the permeability injury of formation is little.There is good application prospect in oil-gas field development.
Clean fracturing fluid is in oil-gas field development, and because the injury of its formation is little, residue content is low, is conducive to the protection of hydrocarbon zone and is subject to widespread use.Non-ionic type clean fracturing fluid nonionic agent is that a class can not ionize in water and whole molecule plays the promoting agent of surface-active action, due to their general anti-salt, anticalcium, antiacid, alkali-resistivity is strong, again not easily with conventional gravitation free radical process and mutually disturb, less to the permeability injury of reservoir, therefore use has more advantage in fracturing liquid.Non-ionic type clean fracturing fluid excellent performance, of many uses, raw material is easy to get and environmental protection, is therefore subject to the common concern of countries in the world.
At the fracturing liquid containing product of the present invention, have and flow change, temperature tolerance preferably, breaking glue solution residue content is low, the feature that the permeability injury of formation is little.
