<p>The invention relates to an apparatus and a method for opening and closing an automatic valve installed in the discharge line of an oil well, characterized by the installation and setup of the apparatus which controls an automatic valve, which is installed in the discharge line of the casing pipes of an oil well. In said oil well a progressive cavity pump system (PCP) has been installed, which pumps the hydrocarbon to the storage tank through the production pipe, said system maintaining the level of hydrocarbon inside the well for improved production. The apparatus to be installed in the oil well consists of three pressure transmitters, which are placed in the discharge lines of the production pipes, casing pipes and in the discharge line going into the storage tank near the well. In addition, in the storage tank, a radar-type level transmitter is installed to keep monitoring the production from the oil well. In the progressive cavity pump engine (PCP) an inductive proximity sensor is installed to monitor the functioning of the PCP pump. All of the transmitters and the inductive sensor are connected to a cabinet which contains the equipment which registers and records the operation of the system, with a system of batteries and recharges by means of solar panels. The method consists mainly of initially characterizing the behavior of the pressures of the well and the production of hydrocarbon during a period of time, analyzing the data and being able to determine a higher or lower configuration of the pressure in the casing pipes, in order to obtain a greater oil production reflected in the level of the tank. Once the operating pressures to be maintained in the casing pipes are determined, the equipment for the automatic valve to automatically open and close is set up to maintain said pressure and thus obtain a higher level of production of hydrocarbon in the storage tank.</p> |
