Description

STAFF CONTROL PROCESS INTENSIFICATING LIQUID PRODUCTION FROM ORSHASH DRILLS AND DEVICE INTENSIFICATION DEVICE

The technical proposal relates to the constructive implementation of systems specifically designed to regulate paralettes during the production of fluids from drilling wells, including through the excitation of special wells}. device di, and can be used to increase the threaded joint of the near-wellbore zone of the reservoir in order to increase the flow rate of the produced I8 well of a fluid (water or oil).

A number of well drilling control systems 7-101 are known, which include measuring sensors (or probes) located in the well and a monitoring and control unit located on the surface made in the form of a processor, and in some} systems (see, for example, , C7) the measured parameters in the control unit are compared with the stored reference data, which allows us to draw a conclusion about the structure of the well structure in depth. However, the systems, being essentially only controlling, do not allow effective control of fluid production

IPC; E21B 44/00, E21B 43/25

from wells, for example, to regulate (increase) the output of the formation by acting on the near-well zone.

A number of known downhole devices 5.63 are equipped with well stimulation modules with corresponding top control blocks and data processing units for downhole sensors (probes).

For example, the well-known technology 23 for processing the near-wellbore zone of a formation includes a device for impacting elastic vibrations, buildings for creating (increasing) fractures in wells, a geophysical probe (sensor system) and a device for analyzing well parameters depending on the depth of the probe installation. The disadvantage of TaKi-ix devices is the lack of control and assessed the impact on the well, as well as the inadequacy of production stimulation devices (USh) specific to Ki-ai requirements, due to the need for effective synergy of the technical result due to the combined use of all devices included in the system.

The main difficulty in the development of special skzazhine SDs, including, for example, a borehole pneumatic source (11ShI) of elastic vibrations, is the creation of an adequate (possibly maximum) signal power (a} amplitude) at a given configuration of the PSI, due to the geometrical shape of the skzazhina, as well as ensuring high synchronization work of SPI. Increasing the amplitude of the signals by grouping the sources in some cases is not effective enough, and in your case (JM the process of synzphonisadia is complicated 143.

in the 90s, SPI (ohm, for example, 3,4,12) were e-patented, the only technically improved ones were: its characteristics, SPI 4,12 contains an electro-pneumatic valve located in the housing, a line of compressed air inlet, a movable shield the rod rigidly fixed inside it, equipped with pistons, the movable cylinder and sherpuo form one or more control chambers and at least one working chamber. In this case, the subversive channel .. as a rule, has a length that is almost commensurate with the length of the SS housing (the pulse is transmitted to the explosion to the working chamber located in the lower part of the housing), which prevents adequate synchronization of the sequence of explosions. The exhaust windows in the device 4 are made in the form of separate holes of small di; shtetra (in the form of perforated holes on the disk), which does not allow to increase the signal amplitude for a given chamber volume.

For E ||) effective management of the process of stimulating fluid production from boreholes, the most appropriate combination of excitation (intensifying) wells should be considered with adequate control of the degree of excitation and control of the flow rate, i.e. well operation with adequate flow rate control with the possibility of increasing it.

Well-known devices are used for prototypes of technical objects combined for a single purpose - to increase the intensification of fluid production from drilling wells of the intensification process control system (LED) and ATC (moreover, the EDM is designed for NGOs, drawing in LEDs), the totality of features of which with an appropriate rational design is the basis for building the proposed technical solution.

The well-known 13ID C13 system, adopted as a prototype, includes a sensor unit (SBU) located in the well, a monitoring and control unit (BKU) located on the surface of the production process and a flow rate estimation unit (VOD), and is also equipped with a USCH, moreover: 1BD, WATER and USCH connected to the control unit

The well-known air traffic control device SZ, intended for use in the secondary school and adopted as a prototype, includes an STI elastic wave, comprising a housing in which an electro-pneumatic valve is placed, a compressed air inlet line with a blasting channel, and a fixed cylinder fixed. inside it is a stock, and the movable cylinder and the body form a control chamber and a working chamber with an exhaust window.

However, in the well-known system SSH1, the flow rate is estimated by the water supply and controlled by the water metering system according to the STD only by measurements in the well, and the spatial characteristics of the near-well zone ke are determined, which reduces the reliability and reliability of production information and excludes the objectivity of judging the potential flow rate wells. The disadvantage of the C1 system is also that flow control is possible only when the production process is stopped. This reduces production rates per unit time. At the same time, the structure of the USH in (ШД 11 is meant to be functionally functional, which complicates the practical real protection and the achievement of a potentially possible technical result.

The well-known SPI 121, like other analogs (see, for example, C41, does not provide potential signal amplitude for given stored volumes of compressed air in the working and control KB epaXs which can be achieved in principle

only with sufficiently large (over op} spherical area) exhaust windows. Loss of energy during the flow of air in relatively small openings increases the efficiency and the KGSC of a pneumatic explosion. In addition, in SPI 31, the length of the subversive channel is not min 1 vd, which increases the delay time. 11J and does not provide the necessary potential synchronization of pneumatic explosions necessary for the correct conduct of excitation ok: vzh1shy

The essence of the proposed technical solution lies in the creation of such a control system for the intensification of production of I8 fluid in boreholes, J which, by determining the spatial characteristics of the borehole zone, would allow for the correct, controlled increase in the intensification of production of fluid with specified quantitative criteria (including a judgment on the feasibility of continuing) with continuous monitoring and control of the intensification process without interruption of work (production), the dryness of the proposed TS As part of the proposed system, it is realized that a special constructive implementation of ET-SH is implemented, which allows you to achieve the highest possible value of the amplitude of pneumatic blasting with the given stored volume of compressed air, and also eliminates the undesirable delay of the response time and ensures adequate synchronization of pneumatic blast.

The main technical result of the system is the increase in the reliability and reliability of production monitoring and control due to the correct regulation of the production process based on the determination of the DIN.ZMIKI of the spatial characteristics of the well The main technical result of the U1SC, which is part of the system, is an increase in the processing efficiency of the entire near-well zone due to an increase in the amplitudes (power ) the impact signal with the stored storage volume of compressed air and, as a consequence, an increase in the production rate of liquid from the well.

Technological1 “1 is the result of the system in synergy with the e (The effectiveness of the USH included in the system provides the combined effect of two technically} objects combined} for the sole purpose of increasing the intensification of fluid production from boreholes.

The technical result in the process control system for intensifying production (SB) of fluid from boreholes is achieved as follows: SC includes a sensor unit (SBU) located in the well., A process control and management unit (BCC) located on the surface and a flow rate estimation unit (VOD), and It is also equipped with a device for intensification of production (USH), with SBD, VOD and ATC connected to the control unit.

Distinctive features of the system are that the system additionally contains a module for geoelectric monitoring (CIM) of the near-well zone made in the form of vertical electrical sensing (ZVEV) and an evaluation module (MOT), with the MCC output connected to the input of the MO, which is connected to the VCU, and The USh is made in the form of a module of the action of elastic vibrations on the near-marginal zone (MVS), which includes a downhole pneumatic source (SJAT) of elastic waves placed in the well by means of a launching device (USP) and connect Device Features nny to input compressed vovduha (IOCTL) and to the electrical control circuit SESU) whose input is connected to.

Moreover, the system is characterized in that the MHC contains at least four control EECs located on the surface in the borehole eon in the corners of the square, in the center of which there is a skeleton, the side of the square for installation being selected in the range from 10 to 500 m.

In addition, the difference of the system is that the MO is implemented in the interior of the processor containing the data storage bay) with (B), a database of data processing rules (LPS), a unit for comparing parameters (BSP) and a block for generating commands (IAC), with the first input The BSP is the input of the MO and is connected to the output of the MCC, the second and third inputs of the BSP are connected respectively to the outputs of the BOD and BCD, the BSP code is connected to the input of the BVC, the output of the BVC is connected to the input of the BCC through the control bus, to which the inputs of the BCD and BOD are also connected ,

In the particular case of performing an SPI, it is located in the well in the zone of the productive formation of the produced fluid, sequentially at several depth s, the values of which are empirically determined in the MO using the values of the summertime measured by the UVEV of the MCC,

In a specific form of execution, standard blocks included in the composition of a computer system or a personal computer are used as a BKU block and as a MO module.

The technical result of the device for intensification of production (UID) 5 made in the form of a module of the cost center is achieved as follows.

a pneumatic spring source (SS) of elastic waves containing a hull in which the electro-pneumatic is located; zlan, LINSH for inputting compressed air about a blasting channel and a movable cylinder with a rod rigidly fixed inside it, and a movable cylinder and body form a control chamber and a working Kai.iepy with an exhaust by the window.

The difference between ATC is that you have a 1-window in the SPI made in the form of an annular hole, the subversive channel is located in the upper part of the body above; the control chamber and the upper case is equipped with a casing-cover with an annular window combined with an annular exhaust port of the working chamber. In a particular case, the working chamber of the secondary school is interchangeable with the possibility of silting on the chamber of the required working volume.

FIG. 1 illustrates the general scheme for building ATS; on Fig, 2 shows the functional structural diagram of the structural implementation of the SS, in Fig.3 is a functional structural diagram of the evaluation module MO; figs. 4 and, plustra, ruins the design of the SPI in terms of the main functional fishing.

The system for intensifying the production of SVD (FIG. 1, 2) contains an SBD 2, VOD 3, BKS 4, MVSh 5 located in well 1, including SPI 6, ESU7, USP8 and UVV9, Sh10, and MGK 11 made in the form, e UVEZ installations 12. The assessment module MO 10 (FIG. 3) contains BCD 13, BPOD 14, BSP 15 and BEK 16, The downhole pneumatic source SPI 6 (FIG. 4) contains a housing 17, an electro-pneumatic valve 18, a compressed air line 19, a blasting channel 20 , movable cylinder 21, rod 22, control channel 23, working channel 24, annular exhaust window 25 and cover-case 26.

On the surface in the near-borehole zone of well 1, MGK 11 is placed, made in the form of UVEV 12 control units, which by the method of vertical electrostatic sounding (VH) measure the quantitative characteristics of the formation (for example, in water production, the resistivity of geoelectric spatial heating from the depth), information about users enter the MO 10 for processing. In the MO 10 assessment module, according to the UVSV 12 measurement data, the dynamics of the spatial characteristics of the borehole zone is determined using quantitative criteria zadavaemy) -; BODA 14, and yes BAB: in: s stored in BCD 13, taking into account the information coming from BCD 13 and BSD 14, the BSP block 15 realizes the comparison of the recorded data}: UVE5 12 with the previously obtained empirical dependence of the pair / meters of the borehole zone (resistivity, depth, etc. Information from BSP 15 is fed to BBK 16, which generates command signals received through BKU 4 to MVSh (UShch) 5 and controls the operation of ESU 7, USP 8, UVV 9 and SSh 6, Block ESU 7 is an electrical control circuit of the SPI 6 located in the well 1 by means of USh 8, air-blast gun 9 It supplies compressed air to school 6, BKU 4 receives information signals from the VOD S, SBD 2, MO 10 blocks and controls their operation. In a specific form of execution, the standard blocks included in the computer system are used as BKU 4 and MO 10 blocks or a personal computer. MGK 11 contains at least four control UBEZ 12 located on the surface in the corners of the rzhadrat, there is a well in the center of the ridge, the side of the square for installation of UBEZ 12 is selectable in the range from 10 to 500 m (10-100 m at water production, up to 500 and - at oil), SS 6 is located in well 1 by hole 8 in the zone of the productive layer of the produced fluid sequentially at several depths, the values of which are determined in MO 10 BS 15 and BVK 16 from the values of the parameters of the deep formation (geoelectric section), measured 12 MGK 11,

A device for intensifying production, including SPI 6, operates as follows. Compressed air from air-blast 9 on line 19 enters the control room 23 and then into the working chamber 24. The compressed air from the SPI 6 ends when pressure reaches a predetermined level and air flow ceases to flow between the chambers 23 and 24, the secondary school is ready for operation, The operation of the G3.43 devices according to the control signal 1 from the ESA 7 is controlled by the electro-pneumatic valve 18 through the subversive channel 20 acts on the clan (subversive eyebrow), which opens, and the movable cylinder 21 opens the exhaust The second window 25, through which air is exhausted from the Kshler 23 and 24, The rod 22 is used for rigid fastening of the working chamber 24 with the upper part of the housing 1 SPI 6, closed by a cover-casing 26 and separated from the 24 ring 4 window, combined with the annular exhaust hole 25 of the working chamber 24, the Case - the casing 26 performs the antisplash functions of the working part of the housing 17, After the exhaust, the movable cylinder 21 returns to its original creep, and the process repeats.

Due to the fact that the exhaust window 25 is made in the form of an annular hole having an area larger, than the total area of all the small holes of the SZ prototype increases, the amplitude (power) of the Akshksh signal increases for a given volume of compressed air, and because the length of the subversive canada is made minimally short (subversive air path minimapen), the response time of the SPI 6 is reduced, the stability of synchronization and the reliability of the device are increased.

In turn, the proposed LED system makes it possible to correctly control the production process by determining the spatial spatial dynamics of the deep formation in the near-wellbore zone.

Thus, the J proposed constructive implementation of the ATS and the SIR included in it allows us to realize a synergy of technical results and to ensure the reliability and reliability of production monitoring and control, together with an increase in the amplitude of the impact signal on the borehole zone, and the extension of the SSS can significantly increase the flow rate of the well

Calculations confirmed by full-scale tests of an experimental model of SPI show that the new design with a replaceable working chamber (when replacing the required working volume with a camera) allows to increase the signal amplitude a compared to prototype 33 by 20-30%, while the relative synchronization increases by 5-15% with an almost constant response time from shot to shot.

The pilot operation of the proposed LED system in relation to the well for water, conducted in 1999 - 2000, g, in the Krasnodar Territory (district g, Novorossiysk) showed that the flow rate of wells increases by 2-3 or more times (with an average number of pneumatic influences of 20- 30, which exceeds the previously established figures for limestone traditional LED systems,
