A Method for the well placement investigation using Productivity Potential Area Map

摘要

The present invention relates to a productivity potential area map (PPAM) and, more specifically, to a method capable of grasping actual productivity and the optimal well location of a reservoir by considering an influence radius which is a degree influencing a grid block according to the position of the well on a productivity potential map (PPM) which is one of existing methods to optimize the location of a well in a reservoir and determine the productivity of the well. The well location search method using the PPAM according to the present invention comprises: a first step of calculating the PPM based on the grid block of a reservoir; a second step of calculating an influence radius formula considering the productivity effect of the reservoir grid block depending on the well location; and a third step of calculating the PPAM by considering the influence radius formula on the PPM. The well location search method using the PPAM according to the present invention has effects of grasping a grid block influenced by a well location and representing the productivity of a well thereby.
