SU36943A1 - Method of detecting oil in the reservoir and increasing production in operating wells - Google Patents

Description

The subject matter of the present invention is neither a detection method nor :. an increase in oil production, in t qoeefe formation of gas in the well, and that penetrates into the oil and seizes oil reservoirs.,. L. V So far, attempts have been made to steal; oil output using electrical heating elements,

which actually led to oil distillation, and to the surrounding ones. the effect of increase in the seam; in terms of temperatures without a significant effect on the viscosity of the oil or on the pressure of the gases on the oil-bearing ones, so

There was no increase in oil recovery.

The proposed invention has 5 steps to find a gas reagent that would be absorbed by the oil, exerted pressure on the sands, and would also be able to block the water channels that lead from the well. For this purpose, it is proposed to inject the electrode in a natural J || H mineralized; water, from the nephritic layer and, by introducing a suitable electrical one, vyzrl; elementalization of water for development; | R

(248) x. ; . .

the gaseous elements of it are absorbed by oil in order to make it more mobile, in order to facilitate the release of its fine sand and rise to the water surface in the well. This occurs in the water at the bottom of the well, where the electrode acts directly for the electrolysis of water. Typically, such a vdd contains salt and the gas obtained by its electrolysis has an alkaline character, which has a washing out effect on the sands, with the removal of oil from them. In the production of this gas, the gases are also released and serve to block the water channels, and the pressure arising from this opens up new channels: in the oil sand, increasing the yield of oil.

. The proposed method can be used at normal processing and during the operation I will pump it out, and the electrically obtained ..: gases are absorbed by the oil and also accumulate in the upper layer and increase the pressure, it is removed from the oil; ,

Essential for the invention in the world is the achievement of electrolysis {oil, not oil, but of natural water in the yokva -., /

for this purpose, an electrical current is introduced at the lowest point with the pacweTOM so that the ascending gases are in oil.

The aim of the invention is a new and improved method for detecting peft, which consists in that the electrode is loaded into its well, which is loaded into its howl, and is supplied with a current of sufficient strength to discharge the gases by electrolysis; the current has an electrolytic effect on the saline water in the oil well to release from it soils, which accumulate and react to the water channels of the well; electrolysis of salt and mineral oil and CHOxix seams gives gases that are absorbed and exert pressure on the oil in the floor (: te, and then locking

-) 1st channels, which leads to the fact that the pressure opens up new channels leading to the well, thus freeing up oil accumulated in cavities and caves or trapped in non-porous areas of the formation. ,, Drawing-illustrates the form of the implementation of the invention. (The pipe 10 Г1rostiraet with to the pocket And, V is closed from above: the lid 2.

  pipe 10 is located pipe 13,

the lower end is connected to the pump 14, from which the perforated pipe 15 hangs. In this pipe,

, on insulators 17, 1 ton, n electrode 16, connected by an insulated conductor 19 to a generator 18. Best results are obtained with electrode "3, uistro iron and with a current of about 50 amceres and a voltage of 2 volts.

Electrical discharge causes. electrolysis at the bottom of the well; the return of the current occurs through the earth or through the neighboring well,

equipped with a second electrode connected to the opposite pole of rtHepaTOpa 18.

-. I

Due to this, electrolysis occurs in the water channels of the reservoir by the scars, and pressure on the oil sands occurs. The water in the well would be poor — these are the salts that are necessary for the development of gases through decomposition of the electrolyte, then the appropriate chemical C9 7

In the case of an extrapolitical decomposition of water, oxygen and iodine develop, and certain mineral salts contained in the water are released. These gases are absorbed by the oil, and act on it, facilitating its flow, and in the sand or oil-bearing layer

The pressure develops, causing its fluid to move toward the scts, n {i.e. ;.

The presence of alkaline substances leads to sands that smelt on the oil, and the accumulation of salt in the water in 1x channels leads to the discovery of novs (x danals through oil-bearing

sandy /

Thus, the proposed method of distillation is located in an oil well to form an aeration / gas for oil; for pressure

on the sands; 1B1p Chemically reacted reactions. and mineral srley.

The subject of the patent.

1. The method of oil leaking in the reservoir and the increase of other & rsi-in e1 float |: boreholes, characterized by the fact that an electrode fed with an electric current of force sufficient to decompose the water into its components, placed under the pump, and the pumping of oil during the action of the electrode does not stop.

2. Modification of the method of pp. 1, characterized in that electrodes are connected to two poles, each connected to one of the poles of a common generator.
