Description

The inventive utility model relates to the oil industry, relates to devices and methods for the preparation of crude oil and relates to the field of delivery and transportation of oil stored in commodity tanks in the pressure pipeline.

Known pipeline transport of viscous and highly solidified oils with heating. (G.S. Lutoshkin, “Collection and preparation of oil, gas and water”, M., 1979, p. 287, Fig. 100).

With this method, the oil is heated at the head point of the pipeline and pumped to the main line. Oil from the field through the field pipeline enters the tank farm. The tanks are equipped with heating devices, with the help of which the oil temperature is maintained, which allows it to be pumped out by booster pumps, which pump oil through the heaters of the thermal station, where the oil is heated to the temperature required by the technological regime. “Hot” oil enters the main pumping station, from where it is fed into the main line by main pumps. To maintain the specified technological parameters when transporting oil over long distances, intermediate heat and pump stations are used.

The main disadvantages of this method:

- the use of this technological scheme is fraught with difficulties due to the bulkiness of the hardware design and significant metal consumption;

- the need to supply a significant amount of any energy from the outside or the availability of sources of fuel supply for the heating process.

There is a scheme for oil field treatment consisting of separators, sump tanks, commodity tanks, an oil heater, pipelines and a metering pump for supplying a demulsifier. (RF patent No. 2142093, IPC Class F17 D 3/14, “Scheme of field oil treatment”).

Disadvantages of the existing oil field treatment scheme:

- significant material consumption;

- the consumption of a large amount of demulsifier;

- the complexity of technology, control and regulation of the process.

The closest to the utility model in terms of content and achieved effect is the method of pumping a liquid, mainly oil, selected by way of a pipeline, selected as a prototype, including its heating to the calculated temperature and pumping under the influence of a pressure drop, and heating the oil is changed so that the measured value of the outlet temperature from the oil pipeline was equal to the calculated one. (AS USSR No. 1105723, IPC Class F17 D 1/18, “Method for pumping liquid”).

The main disadvantages of this method are:

- the need to supply a significant amount of any energy from the outside or the availability of sources of fuel and oxidizer for the combustion process (heating);

- significant material costs for its implementation;

- the complexity of technology, control and regulation of the process.

The disadvantages of this method also include the need to use heat-resistant or heat-resistant materials in the design of the heater.

The purpose of the utility model is to develop a unit for introducing salable oil into a pressure pipeline from commodity tanks while maintaining technological parameters during the transportation of salable oil, simplifying the method of supplying stored oil, reducing the cost of its implementation, as well as saving heat and energy resources.

This goal is achieved by the proposed unit for introducing salable oil into a pressure pipeline containing commodity tanks, supply and discharge pipelines and a pressure pipeline of salable oil with actuators and parameter measuring devices connected to pipelines for controlling flow and temperature and a unit for metering salable oil.

What is new is that the input unit is equipped with a pipe line connecting the commodity tanks to the pressure pipe, while the pipe line is equipped with a metering pump that controls the flow rate and supply of the oil stored in the cargo tanks that enters the pressure pipe and preserves the technological parameters of the commodity oil.

The proposed utility model is illustrated by an example of its implementation schematically depicted in the attached drawing in figure 1.

The unit for introducing salable oil into the pressure pipeline contains commodity tanks 1 supplying 2 and outlet 3 pipelines, the pressure pipeline of salable oil 4, a unit for metering salable oil (not shown in FIG.). The pipelines are equipped with actuators and parameter measuring devices for controlling flow and temperature (not indicated in FIG.). The unit for introducing commodity oil into the pressure pipe is equipped with a pipe line 5 connecting the product tanks 1 with the pressure pipe of the product oil 4, while the pipe line 5 is equipped with a metering pump 6, which regulates the flow and flow of oil stored in the product tanks 1, which enters the pressure pipe commercial oil 4 while maintaining its technological parameters.

The operation of the unit for introducing marketable oil into the pressure pipeline is as follows:

Prepared hot oil is supplied through supply pipelines 2 to storage tanks 1 for storage. During its stay in the commodity tanks 1 there is a decrease in temperature, resulting in

the viscosity of the stored oil increases. For delivery of commercial oil 4 to the pressure pipeline while maintaining the technological parameters, the stored oil is supplied from the commodity tanks 1 through the discharge pipelines 3 through the pump-dispenser 6 and the pipe line 5. The stored oil is supplied to the pressure oil pipeline 4 by a thin stream in a laminar mode.

The oil stored in the commodity tanks 1, at the inlet to the pressure pipeline of the commodity oil 4, is mixed with the hot transported commodity oil and heated due to its temperature, at which the energy consumption for heating the stored oil and pumping it with the specified capacity is minimal and, therefore, trouble-free conditions are met operation of the pressure pipeline of commercial oil 4.

The use of a unit for introducing commercial oil into a pressure pipeline allows you to obtain the following advantages:

The proposed unit for introducing oil into the pressure pipe is simple to perform and maintain, reliable and efficient in operation.

Using the proposed unit will allow for the transfer of heated marketable oil through a pressure pipeline at the most economical of all accident-free modes.

Due to the optimal supply and preservation of the process temperature, pressure and unproductive pumping, a reduction in the consumption of fuel and energy resources was achieved.

When developing the unit for introducing marketable oil into the pressure pipeline, all modern environmental requirements have been taken into account.
