(54) DEVICE FOR PRODUCT DISTRIBUTION OF OIL WELLS

one

The invention relates to devices for distributing the production of oil wells in the oil industry and can be used in other industries as a distributor of fluid flow into several streams.

The closest in technical essence and the achieved result is a device for distributing the production of oil wells, including a container with nozzles for introducing production and gas, and vertical nozzles for outputting products with sections on coitz.

The production of wells in a known device is supplied to the reservoir, then through calibrated holes in the upper ends of the vertical pipes it enters them and is discharged from them through fittings to output products in the form of several streams 1.

The well production is a gas-liquid mixture in which the gas content reaches large values, from a few to hundreds of normal cubic meters per ton of production. The presence of such a large gas content causes the unstable and pulsating nature of the processes in the process equipment of the systems for the collection and preparation of well production in the fields. Due to the fact that the input of well production in the known device is carried out from the bottom through a nozzle, and the output is through holes in the

In the upper part of the vertical nozzles, located in the zone of the most saturated with free gas liquid, into the vertical nozzles, a considerable amount of gas can be withdrawn by the outflow.

Q This leads to an uneven distribution of well production (liquid mixture) along the vertical pipes and the formation of pulsating production flows leaving the vertical pipes and fittings from the device tank. As known,

15 uneven distribution of well production in the form of pulsating flows reduces the efficiency of the following technological apparatus: separators, demulsifiers, etc.

Claims (1)

The aim of the invention is to increase the efficiency of the device for distributing the production of oil wells by increasing the uniformity of distribution and reducing the pulsation of the flows of production of wells. This goal is achieved by the fact that a device for distributing production of oil wells, containing a container with gas inlets and gas outlets, vertical outlet pipes for production with cuts at the ends, is equipped with a vertical pipe connected to the production inlet pipe, and the vertical pipes are bent downwards and their sections are located below the edge of the vertical pipe. FIG. 1 shows the device section; in fig. 2 is a section A-A in FIG. 1. The device contains a tank 1, provided with a bottom fitting 2 for introducing the production of wells, a fitting 3 on the top for venting gas and nozzles 4 for outputting the production. A gas cut-off 5 and vertical nozzles 6 are installed inside the tank, which are bent downward in the form of depressions 7. The lower ends of depressions 7 have angular sections that form calibrated openings 8. Fitting 2 for introducing production of wells into tank 1 is connected to a vertical pipe 9 located inside the tank 1. The upper cut of the vertical pipe 9 is located above the cuts of the downs 7. The device operates as follows. Production of oil wells is fed through fitting 2 and vertical pipe 9 into tank 1, into its middle part. The gas-liquid mixture stream coming out of the vertical pipe 9 rushes up first, then dissipates along the upper part of the volume of tank 1 filled with liquid as the input energy is lost. In this case, the gas is released from the gas-liquid mixture and floats upwards, from where it accumulates as it accumulates through gas valve 3. Moreover, the gas cut-off 5 prevents liquid from entering the gas supply line. At this time, the production of wells, largely free of dissolved and free gas, is, on the contrary, directed downward to openings 8 on slopes 7 and through them, vertical nozzles 6 and fitting 4 are diverted from tank 1 to subsequent process apparatuses. The proposed design of the device and its use ensures uniform distribution of fluid flows through the discharge pipelines and eliminates pulsation of the withdrawn liquid, since the liquid is taken from the bottom of the device tank, where it is largely degassed, and the pulsating gas passes in the upper part of the liquid volume are compensated gas feeder, constantly maintained at the top of the tank. This is achieved by the fact that the upper cut or the outlet of the vertical pipe through which the production of wells enters the tank is located above the inlets in the lower points of the vertical pipes through which the liquid flows out of the tank 1 in the form of distributed streams. Obtaining uniformly distributed and stable in character (non-pulsating) flows ensures the most equal load and effective work of subsequent technological devices of the system for the collection and production preparation of well products and allows carrying out technological processes in design modes. Apparatus of the Invention A device for distributing production of oil wells, including a tank with nozzles of product input and gas output, and vertical nozzles of product output with sections at the ends, characterized in that it is equipped with a vertical pipe connected to the input nozzle in order to increase efficiency products, and the vertical pipes are bent down and their cuts are located below the crotchet of a vertical pipe.
