Análisis técnico de variables y parámetros de perforación para garantizar la limpieza del hoyo en el Campo Tiputini

Abstract

The objective was the technical analysis of the properties of the fluid, drilling parameters and drilling conditions that affected the hole cleaning in wells of high inclination angle (Θ> 50 °) on the Tiputini C. platform, to determine the properties of the drilling fluid (density, plastic viscosity, yield point), and to predict the optimum RPM and ROP drilling parameters to guarantee the cleanliness of the hole. The study was developed based on the variables and drilling parameters obtained from the historical analysis of drilling, by using empirical correlations to predict the operational drilling window and the critical flow in the annular space, which were developed in an Excel sheet. The study of the effect on the critical flow due to the variation of the properties of the fluid and parameters of drilling, was compared with simulators from two oil companies, in order to give greater reliability to the results obtained. For the design of the drilling variables and parameters, the analysis of the same was done by formations. Finally, the drilling systems implemented in the BHA were analyzed to design an optimal system in terms of drilling speed and hole cleanup.
