| Abstract: | The flows through horizontal-well networks can be treated as a flow in rectangular areas with complicated sources and sinks.Its analytic solution is obtained by multiple conformal transformations including elliptical functions,and the pressure and streamline distributions and the well flow rate are presented for the flow field.The impacts of longitudinal and latitudinal well spaces,horizontal hole length and their combination patterns on the horizontal productivity and the flood conformance are investigated.An example is given to show how a well network is designed using the methods and data from this paper.The methods may provided direct theoretical applying and bases for reservoir engineering design. |
