Definitions
- the invention relates to the oil industry and can be used to increase the volume of pumped fluid, increase the oil recovery coefficient, its flow rate, improve the quality and rheological (kinetic) properties, as well as to reduce the loss on the elements of the borehole space (ESP) ) - installation of an electric centrifugal pump (ESP), tubing string (tubing), casing pipe of natural salts (calcium, magnesium, sodium, potassium), hydrated and hydrated left-hydrogen deposits, negatively affecting the operation of the borehole ESP.
- ESP electric centrifugal pump
- tubing string tubing
- casing pipe of natural salts calcium, magnesium, sodium, potassium
- hydrated and hydrated left-hydrogen deposits negatively affecting the operation of the borehole ESP.
- Thermal methods of exposure are used to remove paraffin and resins deposited on the walls of the pore channels, and to intensify chemical methods for treating bottom-hole zones.
- a significant factor affecting production efficiency is the level of protection of equipment and well space from unwanted solid deposits.
- the problem of formation of unwanted solid deposits in oil and gas wells, in production equipment is acute in the oil industry.
- a common process leading to the formation of deposits during hydrocarbon production operations is the precipitation of difficultly soluble salts from the mineralized water of an oil field.
- Some water from oil fields contains a sufficient amount of sulfate ions in the presence of barium, calcium and / or strontium ions, which creates the potential for the formation of barium sulfate (BaS0 4 ) and / or strontium sulfate (SrS0 4 ) in the form of scale.
- the deposits are usually formed from such classes of compounds that include: calcium carbonate (CaCO3), calcium sulfate (CaS0 4 ), calcium sulfide (CaS), barium sulfate (BaS0 4 ), barium sulfide (BaS), barium thiosulfate (BaS 2O3), strontium sulfate ( SrS0 4 ), sodium carbonate (Na 2 C0 3 ), sodium sulfate (a 2SO4), sodium sulfide (Na 2 S), potassium carbonate (K 2 C0 3 ), potassium sulfate (K 2 S0 4 ), magnesium sulfate (MgS0 4 ), magnesium chloride (MgCl 2 ), halite (NaCl), zinc sulfide (ZnS), zinc sulfite (ZnS0 3 ), zinc sulfate (ZnS0 4 ), lead sulfate (PbS), lead s
- Methods for treating chemicals to remove unwanted deposits include acidizing or treating using various other chemicals to remove unwanted deposits.
- the type of chemical treatment process is selected depending on the type of condensate or sediment.
- Chemicals such as polyelectrolytes, phosphonates, polyphosphinocarboxylic acids, organophosphonic acids (such as diethylene triamine penta methylphosphonic acid and hexamethylene diamine tetramethylene phosphonic acid), and polymers such as polyacrylate, polyvinyl sulfonate, sulfonated polymethyl amylates, often use sulfonated polyacrylamates for preventing the growth of unwanted hydrocarbon deposits, such as salt crystals, on the inner surfaces of the production string.
- this solution Upon reaching the maximum volume of a substance that can be dissolved for a given temperature and pressure, this solution must be saturated, and when the conditions under which the saturation concentration of the substance increases, the solution becomes supersaturated. If the necessary seed crystals are present in the solution, the dissolved substances will crystallize out of the solution, and this can lead to sedimentation in the borehole space.
- the positive and negative ions of the substance in the solution must be grouped together. Due to this charge distribution, ions that include more than one atom can be considered as dipoles, and under the influence of an electric field, such ions are oriented with respect to this field. This process significantly increases the chance of collision between charged particles of the opposite charge, since they will move in the opposite direction from each other (especially if the electric field is alternating), and leads to an increase in the growth of clusters of oppositely charged ions of the dissolved substance.
- the electric field reduces the attractive forces that cause the attraction of water molecules to ions, as a result of which the charged particles combine to form a seed crystal.
- Such tiny seed crystals have a surface charge that attracts a large number of ions and their clusters (which can be achieved in a supersaturated solution), and such seed crystals grow rapidly and provoke the growth of other crystals (i.e., precipitation of dissolved substances) in case the solution is no longer oversaturated.
- crystal growth continues until the volume of the dissolved substance decreases again.
- a similar creation of seed crystals in a solution belongs to the field of homogeneous seed crystals; crystals can also form on any foreign substance or on a flat surface with sharp protrusions. Electric charges will be concentrated on any of these protrusions that will attract charged particles to initiate the crystallization process. If there are no available homogeneous seed crystals in this part of the solution, the solute will likewise crystallize on heterogeneous seed crystals, which should likewise be present on the ESP. This is what leads to an increase in sediment on their surfaces.
- a known method of influencing the fluid of oil fields during oil production including the creation of an oscillatory process directly in the processed oil fluid by carrying electromagnetic waves in the frequency range from 3 * 10 "5 to 3 * 10 14 Hz, which modulate information signals resonant hydrocarbons of the processed oil fluid, and form in standing waves (RF patent ⁇ "2281387 C2, E21B 43/16, publ. 04/20/2006).
- the formation of directed standing waves is carried out by a resonant wave device (generator) immersed in kvazhinu and resonance control, standing waves carry field antenna placed on a surface, comprising a movable resonant modules waveguides et al.
- the known method has a significant drawback, which requires a clear interaction of two subsystems - ground and submersible, a complex algorithm for setting up the subsystems and, accordingly, providing an acceptable and reliable communication channel: well - surface,
- the generator generates narrow pulses with a frequency set by the control device to provide free resonant oscillations in the emitter circuit
- the spectrum analyzer unit evaluates the mathematical expectation of the dominant frequency and the dispersion of free oscillations arising in the circuit of the emitter and generates a feedback signal to the control device to adjust the frequency by means of a varicap.
- the wave action on the borehole space is formed by the emitter circuit based on certain a priori settings that take into account one or another composition of sediments on the basis of empirical laboratory and production data.
- this method does not provide the proper level of resonance-wave action on the fluid and the reservoir, taking into account the whole range of parameters of the borehole space. Therefore, it is not effective enough to increase oil production, but is a specialized tool to protect against hydrated and hydrocarbon deposits of a certain type in wells and production equipment.
- the objective of the invention is to reduce the viscosity of the fluid and its separation into light hydrocarbons and energized water, increase the drainage function of cracks, capillaries and pores of the reservoir while reducing the loss on the elements of the borehole space - the installation of an electric centrifugal pump, tubing string, casing pipe of natural hydrated and hydrated hydrocarbon deposits due to the resonant excitation of fluid hydrocarbons and the energization of an aqueous solution of salts at low energy costs using the use of relatively simple technical means.
- the problem is solved by the method of influencing the borehole space during hydrocarbon production, which consists in placing a device with an emitter and a controlled generator to create an electromagnetic wave field in the downhole space at the base of the submersible electric motor to create an electromagnetic wave field in which the radiation of the electromagnetic wave field provides the resonance frequency for the downhole space, previously determined from schegosya experience or simulation results, or in the testing process, the testing process is carried out with a predetermined frequency, and in time periods between testing the generator is converted into the resonant frequency mode, as determined in process testing, for the formation by the emitter of standing electromagnetic waves that distribute wave energy throughout the borehole space.
- the essence of the proposed method consists in the formation in the axial direction of the borehole space of a high-frequency electromotive force (emf) conductivity due to the presence of carriers of electric charges in this space: electrons in the metal, ions in solution, charged solid particles and polarization emf in dielectric molecules, which in turn causes the appearance of a coaxial electromagnetic field inside the borehole space, which, when the emitter is constantly exposed to electromagnetic waves on the resonance second frequency which is predetermined from commercially practical experience or simulation results, or in the testing process, distributed as standing waves. For example, at a frequency of approximately 120 kHz, the standing wavelength will be 2498 m.
- emf electromotive force
- the generated standing waves of the electromagnetic field distribute wave energy in the borehole space, which facilitates the formation of homogeneous seed crystals in the borehole fluid, and, as a result, the crystals formed in the fluid are transported by it without sediment deposits on the surfaces of the ESP, as homogeneous seed crystals attract a substance from a solution ten times more actively than heterogeneous seed crystals on the surface and, as a result, crystals form in the fluid in the form of a suspension.
- the resonance-wave action leads to the excitation and decomposition of fluid hydrocarbons into lighter ones, which leads to a decrease in their viscosity and, as a result, an increase in their mobility both in the well and in the zone of the productive formation adjacent to the well.
- the resonance-wave effect increases the drainage function of cracks, capillaries and pores of deposits due to the release of: - heavy hydrocarbons deposited and adhering to their wall, asphaltene-paraffin-resinous deposits;
- the inventive method is as follows. Before the launch of the well assembly, the sealed generator container with the emitter is attached and connected to the base of the ESP submersible electric motor (SEM). The layout goes down into the well. When starting the PEM, the generator turns on, because the device is powered from the stator winding of the SEM, similar to the prototype. If the resonant excitation frequency is a priori known from practical experience or the simulation result, then the generator starts at this frequency. Otherwise, testing is carried out. For example, the test mode starts, while the generator excites the emitter with a periodic sequence of very narrow powerful pulses. It is known that the narrower the impulse, the wider its spectrum.
- resonant damped harmonic oscillations arise in the emitter with a frequency and damping period, depending on the parameters of the medium. Having determined the frequency and the attenuation period, the generator is transferred to the radiation mode of the resonant frequency with the power due to the attenuation period, which corresponds to the operating mode. Both in test and in operating mode in the borehole space, resonant standing electromagnetic waves appear along its axis.
- the movement of fluid from the reservoir to the production well is traditionally carried out by creating a depression on the reservoir by reducing the dynamic level of the borehole fluid in the casing wells, which corresponds to the well-proven hydrocarbon production technology.
- An important advantage of the proposed method are low energy consumption - the power consumed by the generator for radiation is about 100W.
- the device is localized in the submersible part and does not require additional ground equipment, a communication channel, etc.
- the application of the proposed method of resonance-wave action on the fluid and the borehole space allows to reanimate the wells and significantly extend the life of fields characterized by low flow rates, waterflooding, heavy oils, etc., by increasing the oil recovery coefficient, its quality and rheological properties.
- the method provides protection of the elements of the borehole space from harmful deposits.
