Stream-tube numerical simulation for the linear horizontal-vertical well pattern

In order to achieve efficient and reasonable development in the situation of horizontal well´s widely application in oil and gas reservoirs, further research of horizontal well should be conducted. Researches about horizontal well mainly aimed at productivity while fewer on the development dynamic. The linear horizontal-vertical well pattern model is built, combined with two-phase flow theory the model is solved, simulation of horizontalvertical well pattern is carried out, horizontal well development dynamic is analyzed. The reservoir development dynamic of the liquid production change, the production decline and water cut increasing are given, results comparisons with commercial software ECLIPSE is made, the stream-tube model and solution method´s rationality and correction is validated. There horizontal models of different horizontal length are established and development law of different horizontal well length is given. It is proved that stream-tube model is an efficient tool for carry out numerical simulation for water flooding reservoirs for productivity and fluid flow research.
