A Method for Matching Unconventional Wells and Reservoirs Based on Semi-Analytic Models

Unconventional well technology is often used as one of the most important means to reduce costs and increase efficiency in oil fields. There are many methods for unconventional type optimization, but there relatively few studies on whether suitable reservoir. In this paper, a method matching wells reservoirs established. our method, we first simplify reservoir choose initial types based experience then use semi-analytical model calculate production rate different producing sections. After that, define some parameters evaluate degree reservoirs. Finally, determine these parameters. At end apply specific case. The result shows that stepped exploiting thin interbed reservoirs, it necessary permeability fluid viscosity layers within certain range, shape also limited. This paper gives value range limitation. proposed helpful guiding selection before drilling.
