Establishment and application of recovery prediction model for integrally fractured pattern of horizontal-vertical wells
摘要
Abstract
The coupling flow from matrix to fractures has its particularity in low permeability reservoir fractured integrally with horizontal-vertical well pattern. Infiltration area is divided based on equivalent flow resistance method and superposition principle as well as the principle of flow field division. A recovery predication model is established for integrally fractured pattern of horizontal -vertical wells with multiple transverse fractures which are mutual interference. This paper analyzes the influences of fracture length, number, position and angle on well pattern production, reveals the rule of recovery with such well pattern, and guides the designing of oilfield development program by integral fracturing. The research results indicate that the more the number of fractures is, the stronger the mutual interference of fractures is; there is an optimum number of fractures in horizontal well fracturing; if fractures are aligned at equal spacing along horizontal section, the development response is better when longer fractures arc towards both ends and shorter ones in the middle; if fractures interfere with each other, the closer the fractures are to both ends of the horizontal section, the better the development response is; the target horizontal-vertical well pattern was fractured with a rectangular seven spot pattern, and the optimal angle between fractures and horizontal wellbore is 60°关键词
