The reservoirs of coalbed methane wells have low temperature, low porosity and low permeability geological features, indoor preferred low residue thickening agent, crosslinking agent, to help row agent, breaker, broken plastic activating agent and additives to form a low- damage low temperature and break the plastic fracturing fluid system, and its performance evaluation, found it have excellent temperature resistance to shear performance, thoroughly broken plastic, low fluid loss, low residue characteristics. Through on-site application of the ten wells prove that the fracturing fluid has the effect of sand-carrying, completely broken plastic,made good construction.
