Inventor: TSEPLYAEV YURIJ A
IPC: E21B47/008
Filed: 1993-04-06
Granted: 1997-07-20
Abstract: FIELD: oil production industry. SUBSTANCE: this relates to lifting oil and other liquids from wells which provided with hydraulic actuation equipment. According to method, hydrodynamic investigations are performed. Input and output rates of working liquid are checked. Optimal operation modes are evaluated and, selected are components of jet pump with definite geometrical dimensions. Bottom-hole pressures are determined by calculation at operation of jet pump at transient mode. Working liquid flow rate and well output values are defined. Optimal operation mode is assessed according to maximal values of efficiency at required productivity, recalculation of jet pump component dimensions, replacement of components and final control of buttonhole pressure, working liquid flow rate and well output. For this purpose flow switch is installed between well, gravitational separator and collection system. Gravitational separator mass sensor registers changing of mass in time for preset value within limits of permissible change of liquid level in separator and acts upon flow switch for ensuring periodic evaluation of working liquid flow rate and productive output of jet pump.

Granted: 1997-07-10
Abstract: FIELD: oil and gas industry. SUBSTANCE: device is used to make easier initial drilling of incline or horizontal bore-hole from vertical well. Device has charge of explosive material located in body and also selection of cumulative cones built in explosive charge. Cumulative cones are located along spiral lines of right-hand and left-hand directions. Distance between adjacent cumulative cones is not over three radii of cone base. When device is in operation, cumulative jets created at points of location of cumulative cones break holes in casing string thus making it weaker. Simultaneously blasting products of explosive charge extend pipe. In result of such combined action on pipe wall, cracks appear at weak points and pipe is destructed along cracks. Section of well at preset location is made free for initial drilling of incline or horizontal well. EFFECT: high efficiency. 1 cl, 5 dwg
