Information about the performance of objects (wells) 2 is recorded on a group measuring unit 3 with the help of device 10 The mode of measuring parameters of wells (total water flow rate of water flow and gas flow rate Qr) is set by the device 10 itself according to an adaptive (self-adjusting) program or a discrete program when minimizing total measurement error. The measurement mode is selected at the command of the console .11, by the setting device 14. After the measurement process is completed, the group measurement installation 3 transfers information to the remote control 11. The data collection mode, depending on the object, can be active (mass service method wok) or passive (upon request from the PD) The mode itself is set by the corresponding settings in the device 10 and by the block 15 from the remote controller ll. For dispersed objects - group measurement installations 3 the active mode is selected. The signal of the request (fj-) is received; it is on the unit 12 from the device 10 of the group measuring unit 3, on which the measurement process is stopped and which first sent the request signal (f) to the channel. All other blocks of the device 10 of this direction are blocked until the transfer of information from the selected block of the device 10 is completed. The signal of the request through the node 12 connects the corresponding direction through the block 13, while the other directions are blocked. In parallel, the signal from node 12 is sent to shaper 22, which generates a polling signal f (and feeds it through block 13 and setpoint 14 to the selected direction. The unit 10, which sends the request, receives the signal fonp performs information transfer mode code pulse. By firing at an excellent frequency ff, ep, the measurement information is fed through 12 to block 19, where the daily well performance is predicted from cyclic measurements. The processed information is entered into the unit of the same block 19 and is displayed in digits printing by node 21.. -. --- .-- .., .- Data from the separation-dewatering unit 4 (total fluid flow Q, flow rate of ballast water Qgg, the amount of discharge drainage water Q and the amount of partially dehydrated oil Q, through your device unit 10 is transmitted to console 11 over a millet with a discreteness of at least 1 hour depending on the nature of the raw material intake and its watering. Block 19 produces a summation of expenditure parameters for each separation and dewatering unit 4 and stores the processed information into the memory element of the unit 19 together a downmix mi of water cut feedstream .. installation 5 with a primary oil preparation downmix flow of reactant gas at the heating oil and fresh water flow rate for the desalination unit via its unit 10 are transmitted to the console 11 on request. Information about the amount of oil supplied QH and its quality parameters (water content and salt content) from the unit B of the commercial delivery of oil through its unit of the device 10 is transmitted on request to the console 11. Also on request data on the amount of gas delivered from the installation 8 of gas treatment through. device unit 10 and data on quenching water from the reservoir pressure maintenance objects 7 through its device unit 10. In the object polling mode, objects 4-8 are in the standby mode. Depending on the arrangement of the oil field 1 and equipment. wells 2 information about the reservoir and bottomhole pressure, operating time and energy consumption in the well can also be transmitted to the console 11 through the device 10 on request. This information may come in when conducting well surveys by mobile units on the console 11 or directly to the central control room. Additional information about each object or requests for repair or research work on wells is generated by the dispatcher and, using terminal 20, transmits them to the central dispatch center, where they are, after appropriate sorting and processing, stored in the memory element of the device 34. technical measures (methods of influence on the formation, capital and underground repairs) at the wells are also transmitted by the dispatcher via terminal 20 to the central dispatcher Chersky point. Data on newly introduced wells from drilling objects 9 through the device 10 over the radio channel goes directly to the central control center, where this information is entered into the memory element of the device 34. Thus, operational information about the functioning of all objects of the technological cycle of drilling, production, is generated and recorded. transport, preparation and delivery of oil, associated gas and produced water. In addition, geological information on each reservoir and on each production injection well and statistical material on the operation of facilities is accumulated at the central control room.

According to preliminary information from the test wells, the block 24 osuschestl -, em simulates the operation of individual parts of the developed deposit. As a result of the operation of block 24, optimum conditions are formed for the removal of fluid from the reservoir (bottomhole pressure, reservoir pressure and fluid flow rate) for each well. According to this information block

25, taking into account the planned targets for the extraction of the product (oil) from block 26, organizes a forecast of oil production 15 (0 ") and a change in the water content of the well for each well. The information from block 24, block 25 and block 26 is fed to a setpoint generator 27, which generates for each well 20

average daily fluid withdrawal per month (operating time interval). Data on modes of wells from setpoint 27 and data on planned production targets from block 25.

26 enter the setting point 28, which. generates data on the operation time of each well with a total capacity of 3ai this time. Having information about the planned modes, the system allows -JQ to carry out operational control over the implementation of targets

The information about the performance of each well comes in the request mode from the selected remote control unit 11. Block 35 29 starts the interrogation block 30, which through the switch 31 connects the required direction and starts the imaging unit 32 .. A request signal (fjgp) is formed, which through the switch 31 and the block 33 are transmitted to the selected console 11. The request signal is received by node 12 and fed to a decoder 23, which starts the node 16. The node 16 starts the block 19 in the mode of data transfer recorded 45 in the memory. The data in block 19 is transmitted through node 12 to the central control room. Here, information is received by block 33 and switch 31. The control of receiving information is dried by device 34, which is launched into this mode by block 29 after the signal is sent to it from a form. The world owner 32. The received information enters the computing device 34, where it is processed and sorted. As a result of processing, we have operational information for each well: well number; fpynpa number: liquid debit 0 tons / day; oil debit t / d; water content QB t / day and gas debit Q nm / day. The processed information is then stored in the memory of the device 34, where for each well the geological field data obtained from

In the operational control mode, the device 34 provides information for each individual console 11, which is currently used to assess the actual situation of the scheduled task execution / to the block 36 of the device 34 by a command from the control block 29. Block 36 generates data on the total performance of the selected control panel 11. Upon completion of the formation, block 36 launches the second forecast block 37, which, using real data, generates a forecast for the fulfillment of the planned task for the group of objects under consideration in comparison with the developed modes. In addition, in the forecast, take into account the data on the impact on the object - the amount of water or other injection agent pumped into the formation. Data 6 of the amount of injected water is taken from the third registration unit 41, where it is supplied by the device 34 by the command of the control unit 29. As a result of a comparison of real productivity, modes and targets, block 37 generates constraints on the operation of objects, which it supplies to optimizer 39 in the created situation. The optimizer 39 takes into account the repairs carried out at the sites, information about which comes from block 38, where it is entered when polling the selected console 11. The optimizer 39 generates a refined well mode and feeds it to block 37, which again refines the forecast for the planned task. In this case, block 37 produces a recommendation for the introduction of additional wells in this area. Block 37 starts setpoint 40, which, together with block 24 and device 34, generates a summary of the required number of newly commissioned wells with reference to temporal coordinates and coordinates of the terrain. This operation is carried out separately when developing modes. In addition, the optimizer 39 generates recommendations for the commissioning of idle wells. This information enters the impact classifier 46, which generates information about the necessary repair measures and measures for the intensification of well productivity.

When assigning modes for production skvyzhin, the modes of objects forcing agents (liquids) into the reservoir are formed by block 24 and unit 21 to measures to intensify the operation of the object (corresponding organizational, technical, geological and technical measures) by the driver 48 teams. Third block 41

714403

The registration 11 generates a total result in comparison with the formed modes of impact on the reservoir, and block 39 optimizes the modes and develops the conditions for maintaining these modes taking into account the recommendations of the former 48. Based on the targets from block 26 available for this resource plan and the results of well prediction of the second prediction block 37, the setting unit of the oil treatment mode produces oil treatment modes (separation pressure, dewatering and desalting temperatures, fresh water consumption and reagent and others.). Optimization of modes is based on information about the amount of fluid received from production facilities, which is fed to the oil treatment optimizer 44 from block 42, where the data is received from the device 34. Recommendations are made for the implementation of the raw material preparation plan. In addition, the optimizer 44 and block 42 affect the flow distributor 47, which produces recommendations for the delivery of commercial products to the relevant consumer products. Information about the developed recommendations from the impact classifier 46, setter 40, oil preparation optimizer 44 and distributor 47 goes to the generator 45, which generates a schedule for carrying out activities at the required wells, a schedule for introducing additional wells, the required resources for preparation raw materials and expedient conditions for the delivery of commercial products. This information is digitally printed and stored in the memory. The results are transmitted to the selected console 11, where the information is received by the terminal 20 and printed by the registration node 21, which allows the dispatcher to have recommendations for operating the objects and a list of activities that should be held at the sites. Emergency signaling to the console comes from the objects of the technological cycle as they arise. Signals are received by the receiver 17 of siglization alarms and decoded by the decoder 18. The controller automatically resolves the emergency situation and restarts the object to work. In the event of a complex accident, he sends a request to the central control room, which generates the appropriate control actions and allocates the required resource to eliminate the emergency state of the facility. Thus the controller 11 controls the progress of production, work

 12 with the ability of objects and receives the appropriate control actions from the central dispatch service. At the end of the reporting time period of the operational control, the dispatcher through block 29 acts on block 35, which ensures that the device 34 is launched into the mode of generating reporting documentation on the operation of production by facilities, cycles and as a whole. In this mode, the required monthly reporting indicators are formed, which are then transferred to the cluster information and computing center and digitized indicators for transcoding and delivered to the corresponding process control panel. KIM divisions and statistical bodies. On consoles 11, reception is performed by terminal 20, followed by printing of the document by registration unit 21. At the completion of the calendar time of the operational control stage, the system determines the required modes for all objects of the technological cycle on the basis of information analysis. the past period of operation and. the current state of the objects, taking into account the real perturbations that are possible later. The implementation of this prediction mode is carried out at the command of block 29 to block 35, which starts the device 3.4. The corresponding models, prediction blocks, restriction blocks and mode builders, which form the guesses for the objects of the technological cycle with consideration of disturbances and available resources, as described above, begin to function. BbUje. The results are transmitted to the cluster information processing center, where information processing is carried out, based on the requirements of merging enterprises as a whole. Certain modes are communicated to the respective dispatching services through the equipment of reception and transmission, and these modes will be the most effective control on the objects. The use of the system in the development of oil fields will allow automating the process of developing control actions on technological objects with full information processing taking into account real disturbances in production. The economic effect will be achieved by reducing the downtime of well facilities, assigning efficient measures to intensify production processes, choosing a rational regime taking into account real possibilities and reducing reserves of resources for production. The collection and processing of information will be directly related to the development of control actions, which will reduce its redundancy and data processing costs. The system will make it possible to increase the reliability of control over technological processes, since the role of the subjective factor will be reduced to a minimum and will ensure the implementation of the process control system as a whole. of the invention, an oil production operational control system comprising a command driver, an impact classifier and a measuring device connected in series, a control panel, a data transmission unit, a switch, a computing device and the first registration unit, the second input of the switch is connected to the first output of the request signaling unit, and the third input is K. the first output of the polling task block; ; The second output of which is connected to the first input of the request signal generator, and the input to the first output of the control unit, the second output of which is connected to the input of the program setting block, the third output to the first input of the computing device, the fourth output to the first threshold block, and the input to the second output of the for- maker of the millet, the first output of the threshold block is connected to the first input of the Well performance knobs, and the second output to the first input of the first prediction block connected by the first output to the second Odom backside gchika well productivity, the second input of the computing device is connected to the output of block specifying program.
