Análisis de la interacción formación fluido y su impacto en operaciones de perforación en la región Amazónica del Ecuador

Abstract

In this project the fluid formation interaction and the impacts it causes during drilling of section 12 ¼ be discussed, "for it a detail of the physical, chemical and rheological properties of the drilling fluid, the same way it was done is he did to the physical, chemical properties of the formation especially clays and shales. Later described problems caused by the drilling fluid during the drilling misapplied Section 12 ¼ "through Orteguaza formations, Tiyuyacu, Tena and Napo are those that are characterized by clays and shales. Clay formations drilled into contact with a poor base drilling fluid water swell, while shales in contact with the fluid water-based drilling collapse causing problems during drilling, such as lost circulation, stuck pipe and instability well, among others. By analyzing four boreholes events and processes arising during drilling, in the same way the properties that kept the drilling fluid, in order to describe the impacts caused by fluid interaction formation and the solutions given are detailed fluid to solve these problems. In laboratory three formulations drilling fluid with different amounts of inhibitors in them was analyzed, in order to recommend the properties that a drilling fluid must be maintained during the section for better drilling and minimize problems that are caused by evil use of the drilling fluid. 3 drilling fluids were subjected to physical and chemical testing to determine the plastic viscosity, yield point, the strength of the gels, the filtrate, and the pH before and after aging the fluid order to visualize changes to the fluid drilling has with increasing temperature. With special tests such as capillary suction time, linear swelling and dispersion test is chosen to the best formulation of drilling fluid, to recommend its application in drilling maintaining the properties found in the laboratory. Drilling two wells with the application of the formulation of the drilling fluid showing recommended minimizing problems detailed during drilling. An economic analysis of the benefits of applying the recommended properties in the laboratory, obtaining recommendations and conclusions of the project was made.
