Fo r the low pressure and leakage zone, bare ho le is
always leak ing wh ile dr illing . A lthough it does no t leak, it
just can bear norm a l dr illing flu id pressure. Bare hole can not
bear supernum erary fluid co lum n pressure. In such s ituation,
it can no t create a good situa tion for cementing. In orde r to
guarantee the ha rmony of the w ell drilling and h igh- qua lity
w e ll cementation qua lity requ irem ent, we m ust improve the
ab ility o f bear ing pressure o f the stratum first. The
im provem ent o f ab ility of bea ring pressure must consu lt and
