Ing. Petrleo y Gas Natural PGP 300 PRACTICO 1.- Mediante el mtodo de la presin media y temperatura media, se desea determinar la presin fluyente en cabeza de pozo para los siguientes datos.DatosIng. Petrleo y Gas Natural PGP 300
Ing. Ronald Rodrguez Bolvar Qg= 2,41 MMPCD Pwf=9429 psi Tc= 70 F Prof= 14331 pies Diam= 1,995 pulg Rugosidad= 0,003 SGg=0,65 API= 59 SGm= 0,687 RGC= 71603 pc/Bbl Tr= 270 F Pr= 10477 psiSolucin Para la solucin del siguiente ejercicio, se seguir un algoritmo de clculo, el cual ser el siguiente:1.- Con la ecuacin, calcular Pwh
2.- Calcular Pm y Tm con:
3.- Determinar SGo con:
4.- Determinar SGm
5.- Determinar el %C7+ con:
6.-Determinar Pd: 7.- Determinar la Ppc y Tpc 8.- Calcular Psr y Tsr con:
9.- Calcular las cttes para Z:
10.- Calculo de Z:
11.- Calculo de S:
12.- Clculo de E^s:
13.- Calculo del Numero de Reynolds 14.- Calcular Factor de Fanning
15.- Calcular Grupo 1
16.- Calcular Pwh:
17.- con esta pwf determinar una Pm y asi obtener una nueva zm y volver a repetir todos los pasos
18.- comparar si la Pwh del paso 16 es igual a la Pwh del paso 1.-Si=Fin-No= Volver al paso 2 con la Pwh del paso 16 como dato
