Device for efficient bitumen, shale oil, very heavy and light oil extraction using a fully automated control system and method of preparation of the mining equipment

Abstract

A device for the efficient extraction of bitumen, shale oil, very heavy and light oil that uses a fully automated control system, which consists of a mining assembly in the oil layer and a control unit connected to processing unit, which are on the surface. The mining assembly is provided with a casing which is provided with a perforation, where in the casing an inner riser is arranged and around this inner riser, which is also provided with a perforation and has a firm bottom, whereas the inner riser is open at the bottom and its bottom is above the bottom of outer riser, whereas through the inner riser is led a cable which is with its end anchored in the oil layer to the bottom of the outer riser and with the other end is led to the surface of the control unit, whereas in the space between the bottom and the end of the inner riser at least one sensor on the cable is arranged and it is connected by the cable to the control unit and the control unit is connected to processing unit.

1 . A device for the efficient extraction of bitumen, shale oil, very heavy and light oil using a fully automated control system, comprising a mining assembly in the oil layer and a control unit connected to processing unit, which are on the surface, whereas the mining assembly is provided with a casing which is provided with a perforation,
 wherein in the casing an inner riser is arranged and around this inner riser, which is also provided with a perforation and has a firm bottom, whereas the inner riser is open at the bottom and its bottom is above the bottom of outer riser, whereas through the inner riser is led a cable which is with its end anchored in the oil layer to the bottom of the outer riser and with the other end is led to the surface of the control unit, whereas in the space between the bottom and the end of the inner riser at least one sensor on the cable is arranged and it is connected by the cable to the control unit and the control unit is connected to processing unit.   
     
     
         2 . A method of preparing an extraction device for monitoring the well conditions for the following efficient mining when a processing unit and a control unit are arranged on the surface,
 wherein a mining assembly with an internal riser is provided at the oil layer for the supply of one chemical composition, the cable is sunk into the drill assembly to anchor it in the outer riser for supplying a second chemical composition which is arranged around the inner riser, wherein the cable is provided under the exit from the inner riser by at least one sensor connected by a cable to the control unit and according to the signals from the temperature and pressure sensors, the control unit controls the operation of the processing unit in terms of the inputs of the compositions, catalysts and water according to the preselected operating point.   
     
     
         3 . The method according to  claim 2 , wherein metal-based catalysts such as aluminum, zinc, iron, vanadium, molybdenum, tungsten, manganese, preferably in the form of solutions or suspensions are added to the composition either in advance or simultaneously or with delay. 
     
     
         4 . The method according to  claim 2 , wherein the method is applied analogously to wells led into the oil layers obliquely or horizontally. 
     
     
         5 . The method according to  claim 3 , wherein the method is applied analogously to wells led into the oil layers obliquely or horizontally.
