Influence the formation of acid should also affect the production of oil proppant

In the production process of oil proppants, in sandstone acidizing, the formation fluid and mineral compatibility is very important. Therefore, to determine the potential of acid precipitation mixture of soil minerals and connate water needs careful examination. The product does not have to be dissolved in the acid reaction of residual acid solution or some ionic environment.
The following describes the response to acid formation
Even if the contamination is determined, the situation unworthy team may also occur. A good hsp proppant the fluid system is feasible, the response may determine formation fluids and mineral acid and residual acid. These are not compatible and can lead to cavities solid precipitate, can clog pores, offsetting improvements acid formation. Acidification results may never be completely removed injury impact and there is no harm to the greatest improvement in the formation of acid produced by precipitation or blockage formation.
When can conduct a detailed petrographic analysis of core, geochemical simulation can be used to estimate potential problems. This simulation requires a detailed definition of the chemical characteristics of the construction of the fluid, mineral and matrix formation pollution characteristics. Particle release and finer residual contamination is still possible formation of acid precipitation, which is inconsistent with the core test results.
When we proppant conductivity production of oil, we must pay more attention to the impact on the formation of acid to achieve higher yields.
