The invention relates to the separation installations and can be used to p> Known fractionation device (1) including inlet oil and gas separator with depulsators, gasometrical, sump water separator, buffer tanks for oil and water pumps for pumping oil and water.

A disadvantage of the known centrifuges is time consuming reconstructions its technological units, the need for which is due to the stages of development of an oil field, defined by the percentage of water content in crude production. Reconstruction requires the addition, by combination with existing, necessary technological blocks of different functional purpose or to replace them, and this entails a reconstruction of the whole system: automation, electrical, industrial sites, etc. that, in the end, leads to an increase in the cost of production.

The objective of the invention is the reduction of production costs at the expense of the health of a separation unit n and coupled with depulsators input gas separator horizontal pipe jumper located at the same height with horizontal sections of both demolatorul, all integral functional elements Sep the service piping with shutoff elements, with the possibility of their inclusion or exclusion from the process unit depending on the stage of exploitation.

Comparative analysis with the prototype shows that the proposed separation system characterized by the presence of additional depositor and arrangement of its constituent functional elements in the form of modules connected by piping with shutoff elements. These distinctive features not found in the analysis of the prior art and this allows to conclude that the claimed separation system is new and involves an inventive step.

The drawing shows a diagram of a separation unit.

Separation system consists of a stilling pipe 1, the input gas separator 2 with depulsators 3 for separating gas released from the oil collection system, a heater 4, a three-phase separator-the separator 5 with additional depulsators 6 for selection of gas released by heating the oil, a buffer tank 7 for collecting the partially dehydrated oil pump 8 for pumping oil treatment unit, pressure tanks 9 to clean detachable water reservoir, the buffer tank 10, a pump II for QCD is ora 2 horizontal pipe crosspiece 12, located at the same height with horizontal sections of both separators. This arrangement of the pipe jumpers 12 eliminates the occurrence of secondary pulsations and thereby save stratified for oil and gas before entering the three-phase separator-the separator 5.

Separation system operates as follows.

In the first stage, when the water content is less than 30%, the input oil separator 2 and the oil heater 4 is reserved and excluded from the circuit by closing the inlet valves. Production wells, passing them from depositor 3 horizontal pipe crosspiece 12 is fed through additional depositor 6 in three-phase separator-the separator 5, which performs in this case the role of the inlet separator.

With increasing oil water cut up to 30% and above for the destruction of stable oil-water emulsions require heating, which determines the need for the selection and separation of gas from the stream in front of the heater 4 and its incorporation into the work. For this purpose the valve on the pipe crosspiece 12 is closed, and input the oil separator 2 and the heater 4 open. When this separation system works full version.

In delineating its resistance decreases, that leads to the exclusion of its heating, and input the oil separator 2 and the heater 4 can again be excluded from the scheme.

Thus, the proposed construction of a separation unit provides mobility technology and the possibility of its work in all stages of operation of an oil field without substantial reconstruction.

FIELD: oil and gas production.

SUBSTANCE: invention relates to gas-liquid systems coming from oil production wells. Mixture is separated into liquid and gas in separator. Liquid is periodically accumulated in separator container and then displaced with gas. During this operation, differential pressure for liquid reaching its lower and upper recorded levels and time required for filling recorded volumes are measured as well as absolute pressure and temperature of gas in container. Liquid flow value expressed in weight is calculated using special mathematical dependence. At oil field, liquid and gas enter separator from preliminary gas intake installation or from the first separation step.
