Abstract
This thesis presents new productivity and well testing formulae of

horizontal wells. Taking a horizontal well as a uniform line source,

this thesis finds velocity potential formula and the productivity

formulae for a horizontal well in an ellipsoid of revolution drainage

volume by solving analytically the involved three-dimensional

partial differential equations. These formulae can account for the

advantages of horizontal wells, and they are more accurate than other

formulae which are based on two-dimensional hypotheses. This thesis also

presents new well testing formulae of horizontal wells in a single porosity

system and a double porosity system. Compared with the formulae published in

the literatures, our formulae, which do not use the sum of infinite

series, are more reasonable and easy to be used in well testing analysis.
