Qısa məlumat

The formula for determination of volumetric factor of well spacing for assessment of final oil recovery in reservoirs developed by horizontal wells is offered. For the purpose of comparison of well spacing calculated using conventional and volumetric techniques, twelve development options of the pilot area of the Yamashinskoye field with variousplacement of vertical and horizontal wells were considered. By results of calculations, marked difference in values of well spacing was observed testifying that the conventional formula used to calculate well spacing does not consider the volume nature of fluid inflow to wells with one or more horizontal laterals. The offered technique of volumetric determination of well spacing through the inclination angle, the radius of well drainage area, and the length of a lateral considers the volumetric nature of inflow to horizontal multilateral wells.
