De term ination of g as w e ll ra tiona l produc tiv ity is one o f

developm ent decision among the dev elopment pro ject
p lann ing. Guantao gas cap rese rvo ir o fKD34 block is located
in neritic a rea of Sheng li petro life rous prov ince, and its gas
form ations can t’ perform system atic we ll testing on production
p la tform. Several research m ethods, such as initial econom ic
- lim it productiv ity, c ritica l liquid - carry ing capac ity,
abso lute open- flow capac ity and num er ica l simu lation, w ere
applied to optim ize and determ ine the rational productiv ity o f
gas we l.l The research indicated that the gas w e ll had
obta ined long - term and stable production period w ithout
sand flow, and the deve lopm en t results o f gas cap reservo ir
had been enhanced on the condition that the rationa productiv ity w as contro lled to fifteen thousand cub ic m eters
per day. The produc tiv ity o f gas we lls w ere idea l afte r putting
into production. The research resu lts prov ided a se t of
operational research m ethods fo r de term ining the productiv ity
