Research and application of self-suspending proppants based on block copolymer modification in coalbed methane wells

Qixing Zhang, Zhenbin Zhang, Bo Zhang, Tengfei Sun et autres

Conventional proppants exhibit limited sand-carrying capacity and incomplete gel breaking below 60 °C, resulting in inadequate fracture support and reduced stimulated reservoir volume. In this study, a self-suspending, high-salinity-resistant block copolymer was synthesized by precisely controlling the copolymer composition and topology. Based …
