| jetting methods drążenie hydrauliczne Explanation: Nie mogę znaleźć zastosowania tego terminu ale wydaje mi się, że jego logika jest niepodważalna. Jeśli chodzi o sam "water jet", to mamy w Polsce nawet portal poświęcony tej technologii, ale zajmuje się on przecinaniem przez strumień wody materiałów bardzo twardych, wraz z metalami, więc nie jestem pewien, czy miałoby to zastosowanie, bo tam stosowane są zupełnie inne ciśnienia - godne uwagi jest, że używa się tam tego terminu bez tłumaczenia. W górnictwie węgla znane jest natomiast "urabianie hydrauliczne". Reference: http://www.waterjet.org.pl/ |

| Reference: opis Reference information: Jetted Wells. In the jetting method, you dig a borehole using a high velocity stream of water. The stream loosens the soil and washes the fine particles up and out of the borehole. The jetting method is particularly successful in sandy soils when the water table is close to the surface. Jetting is simple and dependable, and you use hand tools rather than bulky drilling equipment. Two jetting procedures are available washing in a casing or sinking a self-jetting well point. With the jetting method, you can sample the general character of a formation by examining the cuttings brought to the surface in the return flow. - http://tinyurl.com/7as7t ----------------- Jetting Method. With this method, you use a jetting tool that you lower inside the screen. Use the following procedures for this method: Step 1. Attach the jetting tool (in the well-completion kit) to the bottom of the drill string (Figure 7-l). Step 2. Use the string to lower this tool into the screen. Step 3. Connect the upper end of the pipe to the kelly or the discharge side of the mud pump. Step 4. Pump water into the screen and rotate the jetting tool slowly so that the horizontal jets of water wash out through the screen openings. Step 5. Raise the string of pipe gradually and continue rotating to backwash the entire surface of the screen. If possible, use a pump pressure of 100 psi. - http://tinyurl.com/ygosshl |
