Análise da trajetória de poços horizontais em reservatório de óleopesado

摘要

The application of thermal methods, to increase the recovery of heavy oil in maturefields through drainage with multilateral and horizontal wells, has been thoroughly studied,theorically, experimentally, testing new tools and methods. The continuous injection of steam,through a steam injector well and a horizontal producer well in order to improve horizontalsweep of the fluid reservoir, it is an efficient method. Starting from an heterogeneous model,geologically characterized, modeling geostatistics, set history and identification of the bestpath of permeability, with seismic 3D, has been dubbed a studying model. It was studiedhorizontal wells in various directions in relation to the steam and the channel of higherpermeability, in eight different depths. Into in the same area were studied, the sensitivity ofthe trajectories of horizontal wells, according to the depth of navigation. With the purpose ofobtaining the highest output of oil to a particular flow, quality, temperature and time for theinjection of steam. The wells studied showed a significant improvement in the cumulative oilrecovery in one of the paths by promoting an alternative to application in mature fields orunder development fields with heavy oil
