Dan iud i gas field locates in the east segm ent o f no rthern
slope o f Y ishan in the basin o f Ordos. It is a larg e com pound
gas field fo lding to connect into sheet on a flat surface. The
characteristics o f the reservo ir is low-pressure, lowperm
eab ility and low-production. The geo log ic stra ta w ith
m any com plica ted c ircum stance is rather uneven and difficult
to dr il.l The form er techn iques of drilling and cem enting can􀀁 t
adapt to the demand o f the explo itation of the gas fie ld.
Therefore, w e researched the ex isting techn iques o f drilling
and cementing and excog ita ted a se t o f techn iques o f drilling
and cementing w ith fast speed, high-qua lity and low cost.
Deve lopm en t cost o f the gas fie ld is low ered and econom ic
profit is ra ised.
