Description

The invention relates to a power system and can be used to produce (produce) superheated water directly in oil fields with the aim of pumping a high-pressure hot medium into oil reservoirs.

Known devices, the so-called steam generating units, allowing to generate a coolant in the form of steam [1, 2]. Such devices can be used to implement the method of steam and thermal effects on oil reservoirs, which allows to increase oil recovery wells [3, 4]. In this case, the effect of heat and steam exposure depends on the correct choice of equipment for pumping the coolant into oil reservoirs, on the optimal operating conditions of this equipment. In particular, in the monograph [3] it is noted that it is advisable to use superheated high-pressure steam of 9.0 ... 18.0 MPa and higher for thermal treatment of the formation. In order to obtain steam for such needs at the oil fields, various steam generating units of both domestic and foreign production are used. Therefore, any of these steam generating units can be taken as an analogue.

However, steam generating plants produce wet steam supplied under high pressure to the wells, and the design features of the wells do not allow the use of a coolant with a temperature of more than 280 ° C. So, for example, a steam generator unit of type UPG - 60/160, according to the passport data [5], produces wet steam under a pressure of 16.0 MPa with a temperature of 345 ° C, which does not allow the use of such a high-temperature product for most wells in oil fields, whose metal does not have special thermal protection. But even these protective coatings make it possible to increase the temperature of the steam used only to a temperature of 320 ° C. Therefore, in practice, the operation of the steam generator is transferred to the superheated water mode. This reduces not only the reliability of the steam generator itself, but also its efficiency Moreover, when the steam generator is operating in superheated water mode, the flow rate of the coolant for degassing feed water increases, which reduces the productivity of the installation for the final product.

Thus, the main disadvantage of using steam generating plants to obtain a liquid high-pressure coolant (superheated water) is their low efficiency, which is manifested in a decrease in the productivity of the installation in the final product.

In the patent of the Russian Federation for invention No. 2213293 [6] it is proposed to provide the unit with an additional deaerator in which the water taken from a natural source is degassed to increase the productivity of a superheated water production plant, the main unit of which is a steam boiler. It is proposed to install an additional discharge pump on the deaerated water discharge pipe from the additional deaerator, after which the deaerated and preheated water enters a special mixing device. The main flow of steam produced (by a steam boiler) by a steam generator is simultaneously fed into the mixer. After mixing steam and heated water in the mixing device, superheated water is formed as a result of steam condensation, which is supplied to consumers. It is this device according to the patent of the Russian Federation for the invention No. 2213293 and can be taken as a prototype.

Thus, the prototype installation comprises a steam generator, a degasser for preparing feed water with a heating medium supply pipe having a reduction device through which steam produced by the steam generator, chemically purified water supply pipe and degassed water pipe with a feed pump for feed water and a deaerator passes. The deaerator is equipped with a pipeline for supplying water taken from a natural source for deaeration, for supplying a heating medium from a pressure reducing device, and for discharging deaerated water. The drain pipe for deaerated water from the deaerator is connected to the inlet of the high-pressure discharge pump, the outlet pipe of which is connected to a mixing device, into which steam produced by the steam generator is supplied through steam pipelines, and a superheated water distribution pipe is connected to the outlet of the mixing device. The technical solutions outlined make it possible to increase the installation efficiency, which is confirmed by the corresponding mathematical calculations given in the patent description. An analysis of the effectiveness of such a technical solution was carried out in [7–9]. At the same time, two technical solutions were analyzed for the design and layout of the installation for the production of high-pressure superheated water - using one steam generator and using two steam generators.

However, in this prototype there are a number of disadvantages, the main of which is the complex structural layout of the installation for producing superheated water. In the prototype installation, reduction devices are used, which are actually reduction and cooling devices, two pressure pumps are used, for which it is important to ensure synchronization of their work, and the design features of the steam-water mixer are not considered at all in the materials of the prototype patent.

The use of reduction-cooling devices in the device not only complicates the pipeline network of the installation, but also reduces the overall efficiency installation. The use of two independently operating injection pumps in the installation requires their coordinated work, in particular, in the installation, a pump synchronization system is required. More precisely, a control and synchronization system is needed for the operation of power drives of injection pumps. As a rule, electric motors of high power are used as power drives of the pumps. The use of power drives of a different nature for injection pumps will save energy in the field, which is in short supply. One of the most important problems is the provision of high-quality and effective mixing of steam and water in the water mixer, which is determined by the design features of its individual elements and nodes of the steam-water mixer, which require their study.

Thus, installations for the preparation of superheated water, assembled according to the structural layout schemes proposed in the patent of the Russian Federation for invention No. 22213293 [6], have significant reserves for their improvement, as it has its own reserves for improvement and the very method of preparing superheated water by mixing high-pressure steam with an aqueous medium.

Thus, the aim of the invention is to increase the efficiency of the method and the installation for the production of superheated water.

This goal is achieved by the fact that in the method of producing high-pressure superheated water by mixing high-pressure steam with natural water in a mixing device, turbopump units (TNAs) similar to those used in propulsion systems of liquid rocket engines are used as injection pumps with power drives [ 8]. Moreover, the working fluid for the TNA turbine is the steam produced by the steam generator, and the steam at the outlet of the TNA turbine can be used to heat water in the degasser and in the deaerator, which allows you to abandon the reduction devices (reduction-cooling devices). To increase the efficiency of steam-water mixing in a steam-water mixer, it is advisable to supply the mixed components into its working cavity through centrifugal nozzles, as the most effective spraying devices.

Structurally, the above proposals for improving the method for producing high-pressure superheated water can be quite easily realized through the use of elements, assemblies and units of rockets with LRE removed from armament in the design of a high-pressure water production plant as part of their conversion utilization [8]. So TNA, as a rule, consists of two pumps and a turbine installed on one shaft, which solves the issue of synchronization of the operation of pressure pumps. It remains only to adapt the operation of the TNA to a new working fluid - steam. As a mixing device, it is also possible, within the framework of the conversion utilization of rockets with LRE, to use a combustion chamber with a nozzle head, but without a nozzle block. In this case, water should be supplied to the nozzle head of the combustion chamber along the path (fuel path or oxidizer path) that is used in the design of the rocket engine to cool the walls of the combustion chamber. As a result of this, the water passing through the inter-shell path will heat up and reduce heat loss when steam and water are mixed in the working cavity (in the combustion chamber) of the rocket engine.

However, such a structural and layout scheme is to one degree or another optimal for the marching (working) mode of the installation, but there is a problem of starting the installation to the operating mode: how to start the discharge pumps? The pumps can be started and the TNA turbine properly spun up using an additional power electric drive (electric motor), the rotor output shaft of which can be connected (connected) to the TNA shaft through the start-up clutch. Starting an electric motor through a start-up clutch will allow you to start and spin up the discharge pumps of the installation for the production of high-pressure superheated water. After the unit reaches the calculated mode according to the physical parameters of superheated water (temperature, flow, pressure), the mechanical connection between the electric motor and the TNA shaft, that is, with the discharge pumps, is interrupted with the help of the starting clutch.

Thus, the structural layout of the device for the proposed method for producing superheated water is based on the design features of a liquid propellant rocket engine - its heat pump and combustion chamber. Typically, a turbopump unit of a liquid propellant rocket engine is a device with two pumps for fuel and oxidizer mounted on one shaft and a turbine, with the help of which the working blades of the pumps are rotated. The pumps feed the fuel components to the nozzle head of the combustion chamber, from where they enter the combustion chamber through the nozzles, where the components are mixed and burned. For a system for preparing superheated water in a steam-water mixer, it is necessary to mix high-pressure steam and high-pressure water. Therefore, there is no need to save the nozzle block in the combustion chamber: according to the critical section of the combustion chamber, it can be removed and the inter-sleeve clearance can be damped in this section, for example, by installing a flange there. A dispensing pipe will be connected to this flange to drain the prepared superheated water. Liquid must be supplied to the nozzle head of the steam-water mixer through the nozzle nozzle circuit into which the fuel component entered through the inter-tube path of the combustion chamber and nozzle block. Water supply must be carried out in the vicinity of the critical section of the combustion chamber. Having passed through the inter-shell space, the water before it enters the working cavity of the mixer will have time to significantly warm up due to the high temperature of the steam-water mixture in the working cavity (in the cavity of the combustion chamber) of the steam-water mixer. Both the steam in the nozzle head and the prepared water in the inter-shell space of the combustion chamber must be supplied under the same and very high pressure. In this case, the vapor pressure will be determined by the pressure of the working (nutrient) medium (chemically purified water) supplied to the steam boiler. For liquid rocket engines (LRE), the fuel components are fed into the combustion chamber at the same pressure, which is ensured by throttle washers installed in the paths for supplying the fuel components. Using similar throttle washers installed in the water supply paths to the ТНА pumps, it is possible to equalize both the vapor pressure and the water pressure supplied through the nozzle head to the working cavity of the steam-water mixer, which will ensure the effective operation of the ТНА.

On the other hand, the operation of the TNA pumps is ensured by the operation of the turbine, the working fluid for which in the LRE is, as a rule, hot gas produced by a special gas generator. Steam generated by the steam generator may be the working fluid for the ТНА turbine as part of the superheated water treatment system. Moreover, such steam, having passed the turbine, will lose both pressure and temperature, therefore it can be used to heat water in the deaerator and in the degasser. At the same time, there is no need for a reduction device system to lower the steam pressure used to heat the feed water for the boiler (s). On the other hand, the use of a steam turbine as a power drive for TNA injection pumps is possible only for the stationary mode of operation of the superheated water treatment unit. For the unit to enter marching mode of operation, it is necessary to introduce a starting motor (electric motor) for the TNA pumps with a transfer (starting) clutch to transfer torque from the shaft of the starting engine to the shaft of the TNA pumps.

A diagram of such a technical solution, for simplicity considered by the example of one steam boiler, for example, UPG-60 / 160M, is shown in FIG. one.

In accordance with FIG. 1, the installation for producing high-pressure superheated water comprises a steam generator 1, a pressure pump 2 for supplying a working fluid to a steam boiler 1, a degasser 3, with a pipe IV for supplying a heating medium supplied via steam line III from the outlet of the steam turbine 6 ТНА. Pipeline I for supplying deaerated water from its preliminary preparation system (heating and chemical treatment system), not shown in FIG. 1. The installation comprises a pipeline II of the drainage of degassed water with a feed pump 2 for supplying water through the pipe IX to the steam generator 1. The output of the steam generator 1 are two steam pipelines X and XI. The installation is equipped with an additional deaerator 5, in which water for deaeration and preheating comes from a natural reservoir without any chemical treatment through pipeline VI. The water in the deaerator is heated by supplying steam through the steam line V. An additional pressure pump 5 is built into the drain pipe of the VII deaerated water from the additional deaerator 4. The outlet pipe VIII of the pump 5 is connected to the inter-tube path of the LRE 7 combustion chamber in the region of its critical section. Moreover, the section of the inter-neck path in the region of the critical section is drowned out by an annular flange not shown in FIG. 1, and the flange itself is joined with the dispensing pipe, also not indicated by a separate position in FIG. 1, the supply of superheated water to consumers. The installation is equipped with a single power drive of the injection pumps 2 and 5, made in the form of a turbine 6 mounted on the same shaft with centrifugal pumps 5 and 2. In this case, the turbine 6 has a supply pipe for the working fluid - steam line X and steam pipe III for exhaust steam for low-pressure supply and cooled steam in the steam lines IV and V. To spin the centrifugal pumps 2 and 5 and the turbine 6, when the installation for the production of superheated water is turned into the calculated (marching) mode, an electric motor 9 is rotated into it; Currently with the rotor of which by means of the transfer (starting) clutch 8 is transmitted to the axis of the turbopump unit, which are rigidly fixed turbine pumps 2,5 and 6.

A diagram of the mixing device, which is advisable to use the LRE combustion chamber, is shown in FIG. 2.

The working cavity of the mixer, indicated in FIG. 2 by the position of the RP, it is formed by the mixer body formed by two equidistantly located shells 1 and 2 in the form of bodies of revolution, which for the LRE also form the exhaust bell of the LRE. In the mixer for the preparation of superheated water, the annular gap formed by the shells 1 and 2 near the critical section (maximum narrowing of the working cavity path) is hermetically sealed by the annular flange 3. Cover 4 is sealed (welded) to the other end of the outer shell 2 and to the other end of the inner the shell 2 is welded to the intermediate bottom 5, and inside the shell 2 parallel to the intermediate bottom 5 hermetically installed (welded) the main bottom 6 of the mixer. The intermediate bottom 5 and the cover 4 form a cavity (collector) A for one of the working fluid (water), and the bottoms 5 and 6 and the shell 2 form a cavity (collector) B for the other working fluid - steam. On the outer shell 2 near the critical section of the mixer body for supplying water to the path (annular gap) formed by the shells 1 and 2, a pipe 7 is welded to it. Centrifugal nozzles are installed on the main bottom 6, some of which (nozzles 8) supply a working fluid from the cavity (collector) B, and to other nozzles (nozzles 9), the working fluid is supplied from the cavity (collector) A. The superheated water prepared in the working cavity of the mixer (RP) is drawn to consumers through pipeline 10 connected by its flange (not indicated by Fig. 2) to the flange 3. The working fluid (high-pressure steam) is supplied to the cavity (manifold) B through the pipe 11. The pipe 11 is installed (welded) on the intermediate bottom 5, and the steam pipe flange 12 is connected to the pipe flange 11. At the same time, the mixer body and inlet and outlet pipes are thermally insulated: thermal insulation in FIG. 2 is indicated by I.

The operation of the installation for the preparation of superheated high-pressure water has three characteristic modes: start-up mode, operating mode, or marching mode, as well as a stop mode. The efficiency of the installation is mainly affected by the parameters of the marching mode. In this case, the start and stop modes of the installation are mainly characterized by known technological operations for steam boilers, therefore, we will further consider the operation of the installation in marching mode, when the steam generator 1 has started and the transfer (start) clutch 8 has worked, disconnecting the rotor shaft of the engine 9 from the TNA shaft (Fig. . one).

When operating in marching mode of an installation for the production of superheated high-pressure water, chemically purified and preheated to 20-50 ° С water passes through pipeline I to degasser 3, where it is degassed, heated to 70-130 ° С due to the coolant supplied through pipeline IV and having a calculated temperature, the coolant being formed by the steam produced by the steam generator 1 after passing through the turbine 6, in which it was cooled, and then fed through the pipe (s) III to the steam line IV. Degassed in the degasser 3 water through the pipeline IX enters the pump 2, from where, under pressure corresponding to the pressure of the feed water, to the steam generator 1 (Fig. 1).

Part of the steam generated in the steam generator 1 through the pipeline X is supplied to the blades of the turbine 6, ensuring its rotation, and since centrifugal pumps 5 and 2 are installed on this shaft, this will ensure the operation of the pumps 5 and 2. The main part of the steam generated by the steam generator enters the corresponding the manifold of the nozzle head of the mixer 7, which can be used as the combustion chamber of the rocket engine, but without the nozzle block.

In the additional deaerator 4, water for deaeration and preheating comes from a natural reservoir through pipeline VI. In the deaerator 4, the water is degassed and heated by supplying a coolant supplied through a pipeline (steam line) V, and the coolant is formed by the steam produced by the steam generator 1 after passing through the turbine 6, and fed into the pipeline V through the steam line III. Degassed in an additional deaerator 4 to 100-150 μg of residual oxygen per liter and heated to 70-100 ° C, the water flows through pipeline VII to pump 5. Further, this deaerated (degassed) water is pump 5 under pressure commensurate with the pressure of the feed water, coming into the steam generator 1, is fed through the pipeline VIII to the mixing device 7, where the main part of the steam produced by the steam generator 1 is fed through the pipeline XI. Moreover, the pipe for supplying the dehydrated water is installed near the critical section of the combustion chamber LRE for supplying water to the LRE combustion chamber mezhrubashechny tract. 7 steam and water are fed into the working cavity of the steam-water mixer through centrifugal nozzles installed in the nozzle head of the LRE combustion chamber. In this case, steam is supplied through one collector of the nozzle head, and steam is supplied through another collector. The supply of steam and water to the working cavity of the mixer 7 (the cavity of the combustion chamber) through centrifugal nozzles of steam and water allows for a finely dispersed spray of water, which ensures effective condensation of steam and heating of sprayed water in the working cavity of the mixer 7, resulting in superheated water with a temperature 200-300 ° C, which is supplied to consumers through a pipeline not designated in FIG. 1 as a separate position. In this case, the water supplied to the mixing in the mixer 7, in the corresponding manifold of the nozzle head, when it passes through the inter-tube path is heated due to heat in the working cavity of the mixer, which allows to reduce heat losses in the installation and increase its efficiency.

The operation of the steam-water mixer, the circuit of which is shown in FIG. 2 occurs as follows.

Preheated water under design pressure is supplied through pipe 7 (Fig. 2) to the inter-tube path formed by shells 1 and 2, after which water enters the manifold A of the nozzle head. From collector A, water is sprayed (sprayed) through centrifugal nozzles 9 into the working cavity of the steam-water mixer RP. The second working component of the steam-water mixer, steam, is supplied to the manifold B of the nozzle head through a pipe 11, into which it enters through the steam line 12 from the steam generator of the installation for the preparation of superheated water. In the working cavity of the RP of the steam-water mixer, intensive mixing of the working bodies occurs. During steam condensation, the latent heat of vaporization will be additionally generated, as a result of which superheated high-temperature water will have a temperature of 250-300 ° C at the inlet to the pipeline 10. The high intensity of heat fluxes from the working cavity of the steam-water mixer to the shell 2 makes it possible to heat the water flowing through the inter-shell path (annular gap between the shells 1 and 2) to the collector A of the nozzle head, which avoids losses of coolant and improves the efficiency of the mixer.

Neglecting the evaporation losses in the degasser and deaerator by analogy with [6], we evaluate the technical characteristics of the superheated water treatment system. In accordance with the circuit shown in FIG. 1, we will have the following media flow ratios for pipelines of a high-pressure superheated water treatment plant.

For simplicity, we assume that the working media in some lines of the installation are under pressure P _min , and in other lines of the installation are under pressure P _max . In particular, we assume that the following relations hold

The indices in expressions (2) correspond to the positions of the corresponding installation lines. Also, for simplicity, we assume, with the condition of remarks to expression (2), that in the installation for the preparation of high-pressure superheated water in the mains the following temperature ratios are satisfied:

It is known that the power of the turbine ТНА must be greater than the total power of the pumps due to losses in the paths of the turbine [10]. For simplicity, we will neglect these losses, and we choose the turbine power from the relation

where γ is the specific gravity of water.

It is known that, without taking into account losses in the turbine, the power of a single-stage steam turbine is proportional to the steam consumption and heat transfer on it. [10]. Then, taking into account the notation in the figure in FIG. 1 to calculate the power of the steam turbine of the superheated water production unit, we will have

where X ₆ is the steam flow to the turbine; A = const

R and k are the gas constant and the adiabatic exponent of the steam expansion process in the turbine.

Based on the conditions of the heat balance and flow characteristics in the installation paths, we will have

where ΔΗ is the specific heat of water vaporization;

C is the specific heat of water.

The system of equations (1) - (6) allows us to solve the problem of optimizing the operation of the system for preparing high-pressure superheated water in an oil field from the position of its maximum performance in superheated water. The main input parameters for the calculation are the characteristics of the steam generator used as part of the installation, the performance and physical (consumable) characteristics of which are specified in the steam generator passport: optimal pressure ratios at the inlet and outlet of the steam generator; feed water temperature and steam temperature; steam generator performance.

As can be seen from the circuit shown in FIG. 1, in comparison with the schemes shown in the patent [6], the proposed installation scheme for the preparation of high-pressure superheated water is simpler and, as calculations show, the productivity of such a plant for finished superheated water is 10-15 percent higher than for the installation schemes, given in the patent for the invention of the Russian Federation No. 2213293 [6]. Moreover, as a steam-water mixer for such an installation, you can use the LRE combustion chamber with a nozzle head, but without a nozzle socket: steam from the steam generator directly enters one of the circuits (collectors) of the nozzle head; heated water enters the second circuit (collector) of the nozzle head through the inter-tube path of the combustion chamber. To supply fluid to the inter-tube path in the region of the critical section of the nozzle block after trimming the nozzle block, a collector is installed to which a water supply pipe is connected.

The proposal on the design and layout of the installation for the preparation of superheated water, which includes the use of thermal oil and combustion chambers of rockets with liquid propellant rocket engines, allows us to point out one more advantage of the proposed method and device for producing superheated high-pressure water - an effective way of conversion utilization of liquid rocket engines.
