A mud motor (100) for use in oil and gas well drilling includes a reciprocating valve and piston arrangement that generates power using drilling fluid media (e.g., drilling mud) pumped through an inlet port (118) to form a differential across a piston seat (46). The differential pressure causes the valve and piston assembly to move down in an elongated body (111). Rollers (138, 142) then force telescoping, reciprocating fingers (56, 57) to rotate while absorbing the reciprocating up and down action of the valve and piston assembly. This clockwise rotation causes a transmission that includes a clutch shaft (134) and sprags (146) to engage a clutch housing (135) causing the drill bit (17) to turn. Thrust bearings (156) allow weight to be applied to the tool (100) to optimize drilling action. The apparatus can be used in well drilling or in the removal of obstructions (14) such as bridge plugs, metal and rubber from the well bore.

Moteur (100) conçu pour creuser des puits de pétrole et de gaz et comprenant un ensemble soupape et piston effectuant un déplacement alternatif et générant de la puissance au moyen des fluides de forage, à savoir, des boues de forage, pompés à travers un orifice d'entrée (118), ce qui crée une différence de pression à travers un siège (46) de piston. Cette différence de pression provoque la descente de l'ensemble soupape et piston dans un corps allongé (111). Des rouleaux (138, 142) provoquent ensuite la rotation forcée de doigts télescopiques (56, 57) effectuant un déplacement alternatif, tout en amortissant le déplacement alternatif de l'ensemble soupape et piston. Cette rotation dans le sens des aiguilles d'une montre provoque l'accouplement d'une transmission comprenant un arbre d'embrayage (134) et des galets excentriques (146) avec un carter d'embrayage (135), ce qui provoque la rotation du trépan (17). Des paliers de butée (156) permettent d'appliquer du poids à l'outil (100) afin d'optimiser l'action de forage. On peut mettre en application ce dispositif pour forer des puits ou pour enlever des éléments (14), tels que des bouchons provisoires, du métal et du caoutchouc, obstruant le puits de forage.
