Description
Technical field
The present invention relates to oilfield chemistry and use the agent field, particularly relate to a kind of middle low-temperature reservoir sand control with precoated sand and preparation method thereof.
Background technology
At present, along with Gudao oilfield exploitation gradually deeply, deeply taping the latent power in the oil field and expands the limit because the increasing gradually of mining intensity, the situation of shaking out is on the rise.
Anti-sand process technology is one of foundation works of oil-field development, the exploitation that can the oil field maintain a long-term stability, and crucial effects is being brought into play in the development of anti-sand process technology.
Chemical sand control be a kind of be the sand control technique of guiding theory with " Gu sand ", from the essence on stratum, fundamentally control shaking out of stratum.It is to utilize some chemical agents the sand gluing in the stratum, prevent sand movement or form a kind of can only water or the hydro carbons filtration barrier with certain intensity and higher permeability that can pass through, reach the purpose that control is shaked out.
This anti-sand method mainly contains two types: first kind is that sand-fixing agent is injected in the stratum that shakes out, and gets up the loose granule gluing through curing reaction; Second kind is that precoated sand is filled in the stratum that shakes out, and in the stratum, solidifies the back and forms the filter sand system.Because second method is simple and control easily than first method, second kind of anti-sand method mainly adopted in each oil field.
The chemical classes sand-preventing process has the following advantages:
1. be suitable for fine silt oil reservoir sand control;
2. need not overlap and wash and operation such as salvaging, post-processed is easy;
3. construction back noresidue instrument in pit shaft helps series of strata adjustment and multi-level well-completion practice;
4. it is simple and safe to construct, and success ratio is high, and it is high that rate of permeation is recovered.
At present, the coated sand of China's field use, not easy to store, compare cost with mechanical sand control higher relatively.Therefore, mining inetesity is high, and the chemical sand control agent that price is low is significant to the exploitation of understressed sand.
Summary of the invention
Problem to be solved by this invention be to provide a kind of in the low-temperature reservoir sand control use precoated sand, but its long-term storage can use under water, intensity is higher, dosing is few, cost is low, scour resistance is good, temperature tolerance is good.
Another object of the present invention provides the preparation method of the simple middle low-temperature reservoir sand control of a kind of preparation technology with precoated sand.
The present invention solves the problems of the technologies described above the scheme of being taked to be: middle low-temperature reservoir sand control is used precoated sand, it is characterized in that including following component and forms through being mixed with, wherein
