The chemical technique of sand control is one of main way which used to control sand and help to extract petroleum in the oil field. In that case, the sand control agent plays a vital role in it. The performance of sand control agent directly relate to the effects of chemical sand control. Along with the development of sand control technology, especially in the advancement of the performance of chemical sand control agent, many new agents have appeared.
In water by adding 4 to 6% mix, fine sand strata directly into the formation per meter well section for the 3-4cm3, and well 24 hours to put into operation, sand control operations well in advance into the m well section 2.5 ~ 3cm3, shut 4 8 hours to work the next step.
