Productivity evaluation model for infill horizontal well in horizontal injection and production pattern
摘要
Abstract
Productivity evaluation for horizontal well in horizontal injection and production pattern should take the interference of other oil or water wells into account. On the basis of the mirror-image method and source-sink theory, the positive factor and negative factor of productivity were defined. A semi-analytical model of productivity evaluation for infill horizontal well in random horizontal injection and production pattern was built, in which the interference of other wells and the pressure drop caused by wall friction and fluid acceleration were taken into account. The impacts of other oil or water wells' working system and producer-injector spacing on the productivity of infill producer were quantitatively analyzed. The field application results show that the error calculated by the model is less than 15%. It is an effective method for the productivity evaluation for infill horizontal well in horizontal injection and production pattern. The productivity of the oil well increases linearly with the injection rate of water wells increasing. The optimal producer-injector spacing is 1.0-1.5 times of the horizontal well length in someone reservoir of Shengli Oilfield.关键词
