The invention relates to the oil industry and can find application, in particular in technological methods for the separation of fluids on the components the term demolitia), studied in detail and are widely used in practice .It is known that the existing installation demulsification without preheating the emulsion and additives of special reagents (demulsifiers) to delete the booking membranes (natural emulsion stabilizers and impurities at the interface oil - water, preventing the water droplets merge when they collide) are ineffective, so almost all of the produced water-in-oil prepare for thermochemical plants at elevated temperatures with the addition of demulsifiers.These settings have a significant drawback is the large amount of sedimentation equipment (intensity), and the process of preparing oil requires high temperatures and the large consumption of demulsifier.Closest to the technical essence of the present invention is a plant for the preparation of production wells, including interconnected by piping the node pool node destruction booking membranes (urbanized ecosystems) in the form of a Laval nozzle with a narrowing and widening parts and turbulization flow, two-phase separator with branches of oil, gas and water pipe cap is the Torah of oil and water .Disadvantages installation are as follows.1. The difficulty in manufacturing the Laval nozzle (urbanized ecosystems) due to the presence of curved radii of curvature at the inlet and the nozzle outlet, in addition, work on the implementation of curly radii of curvature of the nozzle are costly;
2. Greater intensity due to the presence of two three-phase separators oil and water;
3. Execution turbulizer flow in urbanized ecosystems in the form of very narrow and very short part of the Laval nozzle, which does not ensure the complete destruction of the original emulsion, and as a consequence remove booking shells fully with the phase boundary of the oil-water.The objective of the invention is the reduction of metal structures, its simplification while maintaining the necessary quality requirements of products.The task is achieved by the fact that the Central processing facility production wells, including interconnected by piping the node pool node destruction booking shells with narrowing and widening parts and flow energizers, three phase separator with taps oil, gas, water, according to the invention the narrowing and widening of the node destruction booking shells made in the form of a cone with an angle of view of the cylinder with a length of 5 - 10 diameters.The essential features of the invention.1. The node pool.2. Site destruction booking shells with narrowing and widening parts and turbulization stream.3. Three phase separator with taps oil, gas and water.4. Performing a narrowing and widening parts of your site destruction booking membranes in the form of a cone.5. Performing a narrowing and widening parts of your site destruction booking membranes in the form of a cone with a cone angle of 20 to 70othe narrowing part 2 - 20ofrom expanding.6. Execution turbulizer flow in the form of a cylinder with a length of 5 to 10 diameters.7. The pipelines connecting the node heated urbanized ecosystems and three phase separator.Signs 1-3 are common with the prototype, and the essential features 4-7 are essential hallmarks.The essence of the invention.The known installation preparation (demulsification) production wells for the implementation of the process requires a large consumption of metal due to the presence of two-phase water separators and oil pipe kapleobrazovatelya and end of the divider stages. In addition, we know the x radius of curvature at the entrance and the exit of the nozzle. When passing a stream of the narrowest part of the Laval nozzle does not create high turbulence flow (due to its small length and as a consequence is not the complete destruction of the original emulsion and removal of booking shells fully with the phase boundary of the oil-water.All devoid of these shortcomings, the proposed treatment facility production wells. This became possible due to the proposed implementation of site destruction booking membranes, in which turbulator flow executed in the form of a cylinder with a length of 5 to 10 diameters (more zones establish the flow). This length provides high turbulence flow (minimum Reynolds number of 200,000), which provides almost complete destruction of the original emulsion and removing booking shells with phase boundary oil-water. When the length of the cylinder is less than 5 diameters specified effect is not achieved (achieved or partially), and at length more than 10 diameters of the cylinder unreasonably increases the intensity of the installation.In addition, field tests showed that the implementation of the narrowing and widening parts of your site destruction booking membranes in the form of a cone with a cone angle of 20 to 70othe narrowing part 2 - 20oThis design urbanized ecosystems allows you to direct the treated emulsion immediately in settling apparatus (one three phase separator) without kapleobrazovatelya and end of the divider phase, which usually is the final separation of the feedstock components with the required quality characteristics of products. Moreover, studies of samples of the emulsion at the outlet of urbanized ecosystems proposed design, taken from the top of the stream, showed that its stability (presence of booking the shell) and the water content corresponds to the stability and the water content of the emulsion at the output of the divider phase at the end of kapleobrazovatelya (the prototype). That is why the oil after urbanized ecosystems of the new design, you can send a single stream in a phase separator.In Fig. 1 shows a plant for the preparation of production wells (schematically);

Site preheating 1, urbanized ecosystems 2 and three-phase separator 3 are connected by pipes 7, 8, 9.Urbanized ecosystems 2 is made with a tapering 10 and 11 expanding portions in the shape of a cone with turbulization flow 12 in the form of a cylinder. Tapering part 10 urbanized ecosystems 2 has an angle of taper = 20 - 70oand expanding part 11 has a cone angle = 2 - 20o. The length of the cylinder turbulizer stream 12 is 5 to 10 diameters - d.The device operates as follows. Commercial mixture of water and oil pumped through the pipeline 7 in the node pool 1, where it is heated to the required temperature. Further along the pipe 8 is heated mixture served in urbanized ecosystems 2, where predispersal emulsified water droplets with increasing interfacial surface and removing the natural emulsion stabilizers (leading to reduction of flow of the emulsion). Then through the pipeline 9, the mixture stream is directed to a three-phase separator 3, which is a division of the mixture to phase oil, water and gas and the subsequent recovery of these phases from the separator 3 through the outlets 4, 5, 6.Application of the proposed treatment plant production wells allows CLASS="ptx2">Sources of information:
