Aspectos técnicos dos poços usuais no semiárido paraibano.

Abstract

In this work, we have attempted to analyze the actual data from the field regarding the shallow wells and Amazonas, with particular reference to the semi-arid region of Paraíba, with the purpose of comparing the socio-technical aspects of the two types of wells. The existing conditions of the field were extended through the use of analytical methods using the computer, duly calibrating them, to ensure the validity of comparison and extension. Due to exorbitant costs and high level technology required in the drilling of tubular wells, aspects of implantation of the Amazonas wells were studied, adopting a variety in the diameters and free area (consisting of brick and mortar) to improve filter efficiency through the factor "f "which was conceived in this dissertation. For academic interest, studies have been done that include effects of barriers, sources of recharge, simultaneous pumping / recharging, with various arrangements. This study focuses on the actual field conditions, existing or future, such as interference between wells with poor use of aquifers by farmers, and artificial recharge. The various conditions treated do not exclude the possibility of existence of anisotropy, extratification and other existing complicated situations, thus treating all possible cases, which probably exists due to the complexity of the geology of the Northeastern region.
