Research on fractured horizontal well development law of four injection well horizontal-vertical well pattern
摘要
Abstract
In order to recognize the development index calculation and development rule of the fractured horizontal well of horizontal-vertical well pattern, Green function is used to build the fractured horizontal well formation pressure formula of horizontal-vertical well pattern, then, stream-tube is classified with the help of Euler method, and based on stream-tube method, the development index is calculated.The streamline and pressure gradient field for the fractured horizontal well of horizontal-vertical well pattern are put forward, and the characteristics and the seepage law of the fractured horizontal wells are analyzed.Considering an actual peripheral horizontal-vertical well pattern block, taking four injection well pattern as example, the development index of the fractured horizontal well is calculated, and the development law is analyzed.The simulated results show that the production decline of the four injection well pattern is of index type, liquid production is mainly divided into three stages which are decline at low water cut stage, being stable at medium water cut stage, and rise at high water cut stage, and the water cut rise is mainly divided into three stages which are low and high water cut stages with low reserve recover degree, and medium water cut stage with high reserve recover degree.关键词
