Zusammenfassung:	The inventions are for methods of forming and delivering a treatment fluid into a wellbore. Methods are provided of pumping a first fluid having a relatively high concentration of a particulate suspended therein and pumping a second fluid having either none of the particulate or a relatively low concentration of the particulate suspended therein, and then merging at least the first and second fluids to form a treatment fluid having a merged concentration of the particulate. In one aspect, the first and second fluids are pumped at different average bulk fluid velocities through different pumping chambers of fluid pumps. In another aspect, the first fluid has a relatively high concentration of a hydratable additive and the second fluid has either none or a relatively low concentration of the hydratable additive. This helps reduce wear on the pumps. Procédés pour la formation et la distribution d'un fluide de traitement dans un puits de forage. Selon l'invention, des procédés permettent de pomper un premier fluide possédant une concentration relativement élevée d'une matière particulaire en suspension et de pomper un deuxième fluide ne contenant pas de matière particulaire ou possédant une concentration relativement faible de la matière particulaire en suspension et de mélanger au moins le premier et le deuxième fluide pour former un fluide de traitement possédant une concentration mélangée de la matière particulaire. Selon un aspect, le premier et le deuxième fluide sont pompés à différentes vitesses moyennes de fluides en vrac à travers différentes chambres de pompage des pompes de fluides. Selon un autre aspect, le premier fluide présente une concentration relativement élevée d'un additif hydratable et le second fluide ne contient pas de matière particulaire ou possède une concentration relativement faible de l'additif hydratable. Ceci permet de diminuer l'usure des pompes.
