However, it produces the fracturing liquid in fracturing, which has become one of the current oil field water pollution sources.

但油井在压裂过程中产生的压裂返排液已成为当前油田水体污染源之一。

Based on the well repeated fracturing in Sui-Jing oilfield produced by the fracturing liquid, the implementation of sound processing viscosity can pump directly into the back row of gathering process.

本文针对绥靖油田油井重复压裂所生产的返排液，实施了降粘无害处理，可直接将返排液泵入集输流程。
