Definitions
- TITLE EJECTOR TO IMPROVE DISCHARGE FLOW CONDITIONS IN DRILLING WELLS AND CRUDE TRANSPORTATION FROM STORAGE TANKS.
- the invention relates to a modified JET type pump and specifically, with an ejector that located on the surface acts in the extraction of oils, improving the production of oil and fluids associated with it, acting on the wellhead, as well as well as the invention is oriented to transfer oils from a storage place to another required site through a pipe.
- the invention relates to a jet pump driven by a motive fluid existing at the application site, such as water extracted from the wells and separated from the oil to be reinjected, as a fundamental operating element for the jet pump, improving the environmental conditions because it is not required of other energy sources such as electricity or fuel for its operation, also being highly economical because its operation and maintenance costs are very low.
- a motive fluid existing at the application site such as water extracted from the wells and separated from the oil to be reinjected
- This modified jet pump for the purpose indicated here is called the Ejector, and it has some variables in its structure and composition that make it innovative and inventive.
- Jet Claw pump In the oil industry, equipment that uses the Venturi effect for oil extraction is also used, an example of which is the Jet Claw pump. These devices have also been adequately modified for that use.
- Another example is the jet pump of the US47184S6A patent, in which it is shown that jet pumps have been developed that can be moved in a truck to the oil extraction wells, in which they are installed through the existing cable lines in themselves.
- Other reference patents may be JP2004293509A, W02016084035A1 or application W0200303601 1 A2, of which the latter already have US patents, all of which refer to modified jet pumps for specific uses with characteristics different from that of the present invention. .
- the present invention is developed on the basis of this knowledge and is applied to develop the ejector that allows solving an existing problem, which is the transfer of extracted oils and derivatives, at the lowest possible cost from storage tanks of extracted oils and their derivatives, to pumping substations or to other storage or distribution systems required.
- the ejector of the present invention is aimed at improving the production of oil wells, when they act by decreasing the head pressure of the production well, whether the extracted oil is being pumped by jet pumps of the Jet Claw pump type, or by pumps electric submersibles, improving the operating conditions of the well and, as a consequence, raising the production level because the discharge flow is increased.
- the resulting flow rate is much higher than that achieved by electric or fuel pumps, considerably reducing storage time in the tanks and avoiding contamination by spills occurring therein; it is also possible to save the emptying time of the tanks, whose content needs to be driven towards substations or distribution systems according to the requirement from one location to another.
- the new device designed in accordance with the results obtained by applications of variants in mathematical models, is designed as an ejector that, installed on the surface, serves to support other equipment for oil extraction from the bottom of the well, increasing the production flow.
- the designed ejector can perform several functions, among the most important are the reduction of back pressure in the wellhead, support in the restart of wells by cleaning the preventive or "killed" fluid, the fluid transfer between production stations, application in compressor stages, etc.
- this invention relates to the development of new ejector models, through a better design thereof, which responds to variations in proportion between the essential parts in accordance with the use and application required and with the quality of the fluids, which comprise the oils extracted from the wells together with their extraction components.
- the new ejector model which responds to the characteristics of these processes, which affect the modification of the parts that compose it, such as the relationship that must be established between the diameters of the mouthpiece and throat, and always using the motor fluid and the Venturi effect for suction, these have been shown to be handled within the ranges indicated in the previous table.
- the present invention solves the aforementioned problems and others in which the ejector can operate on condition that a motive fluid is available, thereby reducing, with much advantage, the costs of operation, maintenance and installation, since the use of the motor fluid is optimized, of almost non-existent cost under appropriate conditions for this, as is the case with the liquid fluids or gases of the deposit, where one of the extraction products is the formation water that is extracted together with the oil, and which influences the reduction of operation and maintenance costs for the fluid transfer system using the ejector object of the present invention.
- the maintenance cost of the device object of the invention is almost nil, since it has no moving parts for its operation and is very easy to be transported and coupled anywhere, which makes it versatile for pumping where required, as well as - as explained - also to be used in support of the extraction of oil wells.
- the ejector apparatus of the present invention unlike the prior art pumps, takes advantage of the Venturi effect to suction the fluid stored in storage tanks and drives it through the throat (fig. 1 .7 ) to the mixing tube (Fig. 1.9), where it meets the motive fluid that operates the ejector apparatus; The mixing of these two fluids is driven through the discharge to the pipes that go to the final storage sites.
- the ejector Being a surface apparatus, the ejector is easily installed by conventional means at the site intended for use, without requiring additional complex external energy sources. It is only necessary to connect the inlet pipes for the motor flow, the suction pipe and the discharge pipe, through the respective valves and conventional connecting elements.
- FIG. 1 DESCRIPTION OF THE JET SURFACE EJECTOR OR PUMP.
- the ejector or surface jet pump is shown in fig. 1, and consists of the following parts: injection nozzle connector (fig. 1 .1), ejector body (fig. 1 .2), outer tube of ejector (fig. 1 .3), seal body of the ejector (fig. 1 .4), Venturi Claw nozzle (fig. 1 .5), nozzle retainer (fig. 1 .6), Venturi Claw throat (fig. 1 .7), throat housing (fig. 1 .8), diffuser (fig.
- the body of this ejector (fig. 1 .2) or surface jet pump has 3 ends (A, B and C) to connect to the pipes of the system in which it will operate.
- the pipe that provides the motor fluid or injection fluid is connected at the end A (fig. 1) by means of a 50.8 mm Hammer joint (fig. 1 .17) and a neplo (fig.
- Figure 2 corresponds to the description of the outer shell or body of the ejector or surface jet pump (fig. 1 .2), seen from a longitudinal cut perspective, where its main characteristics are described, which confirm and guarantee compliance with the functions of the ejector or surface jet pump within the specific ranges indicated above.
- This element therefore, being fully exposed to the environment, provides the ejector or surface jet pump with the necessary strength and resistance against the elements and the environment.
- the ejector or surface jet pump (fig. 1) is used according to the flow chart of (fig. 3) for fluid transfer.
- a motor fluid injection line is connected through a valve (fig. 3.18) and an automatic valve (fig. 3.19) connected in series next to the injection side (fig. 3.A) of the ejector (fig. 3.27).
- the automatic valve (fig. 3.19) for opening or closing receives signals from controllers of maximum level (fig. 3.22) and minimum level (fig. 3.23) through an electric line (fig. 3.21).
- a fluid line to be transferred out of the storage tank (fig. 3.30) is connected through a valve (fig. 3.18) and a check valve (fig. 3.20) connected in series, to the suction side (fig. 3 .B) of the ejector (fig.
- the discharge line of the mixture is connected from the discharge side (fig. 3.C) of the ejector (fig. 3.27) to the main transfer line (fig. 3.25) through a check valve (fig. 3.20 ) and a valve (fig. 3.18) connected in series.
- the sensor sends an opening signal to the automatic valve (fig. 3.19), thus allowing the entry of fluid from injection into the ejector (fig. 3.27), through the respective valve (fig. 3.18) and the injection end (fig. 3.A), and due to the venturi effect, the fluid stored in the tank is caused (fig. 3.26) is suctioned by the suction end (fig. 3.B) into the ejector (fig. 3.27), where it is mixed with the motive fluid to be driven through the discharge side (fig. 3.C ), towards the main transfer line (fig. 3.25).
- this application of the ejector or surface jet pump (fig. 1) is very beneficial in the transport processes of fluids, not requiring for its operation of electrical installations or complex fuels that pollute the environment, as is the case when electric or fuel pumps are applied for this purpose.
- the ejector or surface jet pump (fig. 1) is used according to the flow chart of fig. 4 to lower the pressure in the head of an oil well, thus improving the operating conditions and production flow of an oil well bottom pump,
- a motor fluid injection line is connected through a valve (fig. 4.18) to the injection side (fig. 4.A) of the ejector (fig. 4.27).
- An oil production line leaving the head (fig. 4.30) is connected through 2 valves (fig. 4.18) in series, to the suction side (fig. 4.B) of the ejector (fig. 4.27).
- the discharge line of the mixture is connected from the discharge side of the ejector (fig. 4.27) to the storage tanks through a valve (fig. 4.18).
- this application of the ejector or surface jet pump (fig. 1), is very beneficial in the production processes of the oil wells, since by lowering the pressure in the head thereof, the operating conditions and the production flow of the respective well bottom pump improve.
