Description
Technical field
The present invention relates to the heavy crude thinner that a kind of oil-field development is used, relate in particular to a kind of steam of accompanying with viscosity-depression agent and the preparation method of the super viscous crude of high temperature resistant spy.
Background technology
At present, the general waterflooding in common heavy oil oil field, the general exploitation via steam injection of special super viscous crude field.To annotate the vapour quality in order improving, to reduce viscosity of crude, be aided with usually with viscosity-depression agent and exploit.In some oil-field thick-oil block, general viscosity of crude is at 2000～70000mPa.s, and is mobile poor because viscosity of crude is big, brings difficulty for defeated the adopting of exploitation and collection.The viscosity-depression agent of oil field use at present has oil-soluble viscosity reducer and water-soluble viscosity-depression agent, and oil-soluble viscosity reducer is generally inflammable substance, flash-point lower (more than 30 ℃).Consider the on-the-spot security of using, adopt water-soluble viscosity-depression agent usually.Water-soluble viscosity-depression agent is generally basic cpd or tensio-active agent, or with the compound of other medicaments.Because the difference of oil property does not have a kind of water-soluble viscosity-depression agent that is fit to all viscous oil recoveries.Therefore in the triturating of viscosity-depression agent, should according to the viscous crude character of specific oil field, particular block to institute's with medicament estimate, screening, composite, thereby select best medicament and consumption.Commercially available water-soluble viscosity-depression agent model has GDH-02, XJN-1 at present, and at the Lean viscous crude, both viscosity break ratios are about 71.0～90.0%.GDH-02, XJN-1 viscosity-depression agent are behind 300 ℃ of following thermal treatment 24h, and viscosity break ratio drops to about 70% by about 90%.This is that the part material easily decomposes when high temperature, poor heat stability because this type of water-soluble viscosity-depression agent contains, and causes the viscosity-depression agent non-refractory.At the special super viscous crude in Lean, present commercially available viscosity-depression agent exists that viscosity break ratio is low, the problem of temperature tolerance difference.
Summary of the invention
The present invention is intended to overcome the deficiencies in the prior art, and one of purpose provides a kind of viscosity break ratio height, the special viscosity reducer for extremely-viscous oil of resistant to elevated temperatures companion's steam; Two of purpose provides the preparation method who realizes one of purpose.
One of purpose of the present invention can realize by following technical measures:
This viscosity-depression agent is made up of following raw materials in weight portion:
Petroleum sodium sulfonate formaldehyde condensation products 40～65
Polyoxyethylene nonylphenol ether sodium sulfonate or polyoxyethylenated alcohol sodium sulfate 10～30
Sodium bicarbonate 1.0～2.0
Water 10.0～30.0
High temperature film spreading agent 2.0～5.0.
One of purpose of the present invention also can realize by following technical measures:
Described petroleum sodium sulfonate formaldehyde condensation products is 48～58 weight parts; Described polyoxyethylene nonylphenol ether sodium sulfonate or polyoxyethylenated alcohol sodium sulfate are 17～23 weight parts.
Two of purpose of the present invention can realize by following technical measures:
This method is carried out as follows:
A. sodium bicarbonate and high temperature film spreading agent are added to the water, are stirred well to dissolving, get lysate;
B. the petroleum sodium sulfonate formaldehyde condensation products is joined in the lysate of a step, be stirred to dissolving, get mixed solution;
C. polyoxyethylene nonylphenol ether sodium sulfonate or polyoxyethylenated alcohol sodium sulfate are joined in the mixed solution of b step, be stirred to dissolving, get product.
General oil field is that 15-18MPa, temperature are under 350 ℃ the reservoir condition at super thick oil filling steam pressure, consider thermosteresis, basically at 300 ℃, it is 55000.0mPa.s(50 ℃ that viscosity-depression agent performance of the present invention can make viscosity of crude) super viscous crude, viscosity break ratio reaches 99.8%, viscosity-depression agent is placed in 350 ℃ the high-temperature airtight container behind the aging 24h, measures the viscosity break ratio of this viscosity-depression agent still more than 99.1%.Therefore can satisfy the on-the-spot use of special super viscous crude, this viscosity-depression agent can inject stratum (the pre-notes) before steam treatment, also viscosity-depression agent can be injected stratum (companion annotates) with steam.Laboratory test results shows that the companion annotates effect and is better than pre-notes at present.
