Abstract
The study on enhanc ing o il recove ry of ord inary heavy oil reservo ir w ith gas cap is much less. The m a in conflicts are tha t the o il production is raised as much as poss ible and the gas channeling w on t occur when the energy of gas cap is utilized ra tiona lly. A cco rding to the study of a examp le, the conflicts can be so lved by introduc ing the techno logy o f hor izonta lw e lls on the bas is o f optim ization o f param eters o f hor izonta lw e lls.
