TheW ellTuo 17 in Shuang tuozi g as field w as com pleted
on July 10th 1998. So far an unstable w e ll testing and a
m od ified isochrono l testing w ere conduc ted. A great deal o f
inform ation was ob tained by interpretation o f produc tiv ity test
and pressure bu ild-up test data. B ased on doub le- log and
sem -i log analysis, the outer bounda ries of this w e ll are two
paralle l fau lts, wh ich a re co rresponding w ith the geolog ica l
cond itions. It is presented tha t the se lection o f the
interpretation m ode l is ve ry importan t fo r we ll testing
interpretation. A correct judgm ent shou ld be m ade by
comb in ing g eo log ical cond itions and curvem orphology of w ell
testing. The true sk in factor is determ ined to be about 0 by
using mod ified isochrono l testing of this w el,l how eve r, the
interpretation resu lt of pressure build-up test show s tha t the
production quo ta is too high and the turbulent loss is ser ious.
The open flow capac ity of productiv ity test is determ ined to be
108. 582 thousand cubic m eters per day, and the reasonab le
production is dete rm ined to be 21. 7 thousand cub ic m eters
per day by using one fifth of open flow capacity.
