垂直裂缝井稳态产能的计算
The calculatoin of stable production capability of vetically fractured well
摘要
Abstract
The seepage flowing pattern of an oil well with vertical fractures is transferred to a simple single direction flowing one by using the method of conformal transformation. After that, a secondary pressure differential equation of seepage flowing with a character of changeable quality in fracture is derived on the basis of seepage flowing analysis of microelement; and of material balance theory as well as Darcy's law. What's more, the theory of pressure coupling (the pressure is equivalent at the joint of the fracture and the matrix) is also used. Therefore, an equation of estimating oil rate of a hydraulic fracturing well is available which has a various fracture length and conductivity (finite and infinite). Compared with some classical charts and the real postfracturing performance, excellent agreements can be abstained. Furthermore, it is not only simple but also feasible, so that it can be put into field application conveniently.关键词
