wellbore storage must be considered for a pumping test without an observation well (single-well
test). Based on such characteristics of the time-drawdown curve, we developed a new method to
estimate the aquifer parameters by using the genetic algorithm.

摘 要：Flow to a partially penetrating vertical well is made more complex by intra-
wellbore losses. These are caused not only by
the frictional effect, but also by the kinematic
effect, which consists of the accelerational and
fluid inflow effects inside a wellbore. Existing
models of flow to a partially penetrating vertical
well assume either a uniform-flux boundary
condition (UFBC) or a uniform-head boundary
condition (UHBC) for treating the flow into
the wellbore. Neither approach considers intra-
wellbore losses. In this study a new general
solution, named the mixed-type boundary
condition (MTBC) solution, is introduced to include intra-wellbore losses. It is developed from
the existing solutions using a hybrid analytical-numerical method. The MTBC solution is capable
of modeling various types of aquifer tests (constant-head tests, constant-rate tests, and slug
tests) for partially or fully penetrating vertical wells in confined aquifers. Results show that intra-
wellbore losses (both frictional and kinematic) can be significant in the early pumping stage. At
later pumping times the UHBC solution is adequate because the difference between the MTBC
and UHBC solutions becomes negligible.
