Abstract

The invention relates to the oil industry, in particular to the collection and preparation of well production. The aim of the invention is to increase the performance of the phase splitter and the separator and improve the quality of processing of well products due to the selection of additional oil and water in addition to gas by autonomous streams at various levels.

Description

The invention relates to the oil industry, in particular to the collection and preparation of well production, and is an improvement of the method according to the author. St. No. 1093874.

The purpose of the invention is to increase the performance of the phase divider and the separator and to improve the quality of the processing of well products by additional extraction of oil and water by autonomous streams at various levels.

The drawing shows the implementation of the proposed method.

Watered gas and water mix

fluid, with gas factor 67, is directed to a KDF model with a diameter of 10.2 cm and a length of 6 m, where it splits into a gas with a density of 1.32 kg / m, oil 5 with a density of 877.6 kg / m and saline water with a density of 1016 kg / m, which, without mixing, move one above the other, under the influence of a pressure differential of 0.25 kgf / cm., are taken by nine autonomous streams using tubes 0 6 mm in diameter, the lower ends of which are uniform, with an interval of 1 cm , are placed along the flow cross section at different heights of KDF. The flow rate of gas, oil and water is 2.5: 1. Under pressure

sent through the collecting pipeline 1 in the 5th separator in the order of 0.5 kgf / cm, the terminal divider of 2 phases (CDF) is reached, where it has a specific capacity of 214 days. stratified into gas, oil and minerals. At the same time, the quality of gas is characterized by lysed water, which, without mixing with the content of droplet oil, no more than move one above the other and under the air of 50 m, the quality of oil is due to the pressure differential LR (Pi-P2 ) water is not more than 5%, water quality is

They are collected in a multitude of (autonomous) 20 oil streams with a content of 22 mg / l and an EHF of 36 mg / l with help of 3 tubes of the calculated diameter, compared to the water content in the oil

with a known method of more than 10%, respectively, of oil in water 60 mg / l and EHF 50 mg / l.

device 4 of separator 5 on different Autonomous inlet of the exfoliated tubes — one above the other — in the same phase (oil-water) into the separator according to

The proposed method eliminates the emulsification of free water with oil, which leads to an increase in the depth of oil dehydration and an increase in the quality of the return ends of which are evenly placed over the cross section of the flow at different CDF heights, and the upper ones are put into the receiving

sequence, as in the selection. The gas from the receiving device through pipe 6 enters the gas zone of the separator, and the multilayer fluid flow, keeping the same

the structure, as in KDF, flows into the lower formation water. At the same time, the capacity of the three-phase separator increases threefold and, accordingly, capital expenditures are reduced during the construction of separation plants, and water purification costs are eliminated.

With fluctuations in gas, oil and water consumption, the phase boundary in CDP rises or falls, thus blocking the input part of certain tubes and thereby automatically increasing or decreasing the flow rate of the corresponding phases and their intermediate layers through or through them. The accumulating oil in the separator is poured over the edge of the box 7 and discharged from it through the pipeline 8. The partition 9 is lifted up to the method of transporting the gas-water and neft mixture according to the author.
