Desenvolvimento do simulador para análise do gradiente de pressão na elevação de petróleo

Abstract

It is of utmost importance that increasingly is studied techniques that improve the methods of oil lifting and knowledge that is related to that area. One of the key factors for hydrocarbon production is the control and knowledge of pre ssure throughout the well . The objective of this work was the creation of a computational tool able to simulate the flow in a production column, can be calculated and analyzed the pressure gradient behavior during the flow. The simulat or was developed by Lucas Bruno Russo and Silva Rocha and Igor Belizário Rocha. To determine the pressure drop was us ed the method of Beggs & Brill, t his method can be used to flow in any pit slope angle and direction of flow. In order to get closer to rea lity it introduced a marching algorithm where the parameters are obtained by section in the well and t hrough empirical correlations of the properties of the fluid inserted in the program, one can capture the changes of pressure and temperature conditions i n each subdivision of the production column. The routines and lines of code have been implemented in Microsoft Office Excel®, which allowed the creation of an automated spreadsheet and graphical user interface facilitates user handling. The data in the spr eadsheet can be viewed graphically favoring the reading and understanding of the results. The validation of the sheet was performed by computational experiments, comparing the results obtained in the program with default values in the literature and in com mercial simulator PIPESIM®. The sheet showed a good performance to simulate the two - phase flow and can be applied as a tool to help lift oil projects
