Description
Technical field
The present invention relates to a kind of in petroleum exploration and development work, use the transmission of myriametric wave signal and simulated pressure ripple code signal to carry out the multinomial device of controlling operation to the intelligent actuator of down-hole, its feature is that can realize fixed tubular column carries out: the oil production by layer of tune, multilayer is surveyed online in the water filling of multilayer, the productivity test of multilayer, look for the formation pressure of dynamically testing envelope, multilayer and the thermograph of water blockoff, multilayer, and uploads to intelligent actuator control system under a kind of multifunctional well of ground receiving equipment.
Background technology
In oil exploitation process, in order to improve crude output, water filling is one of important Means To Increase Production at present, and in this process, in order to realize science water filling, meticulous water filling, need to carry out to each layer of water injection well the allotment of water injection rate according to geological design.Conventional method is to chew by pulling mine water repeatedly at present, and the size of chewing by replacing water reaches design injection allocation requirement.In implementation process because of fouling, corrosion, the factors such as hole deviation, cause pulling allotment time-consuming, success rate reduces, operating cost is higher.In the process of recovering the oil, need liquid-producing capacity, water outlet situation to each interval to grasp, conventional method is by operation team lower many times tubing strings repeatedly, to each layer of oil well, respectively with bridging plug envelope card, the yield data and the moisture data that then record each layer are determined mined bed.If multilayer is exploited simultaneously, need to each mined bed, carry out packing with packer, routine is tested envelope need to be lowered to pressure gauge after setting operation, after the static pressure of each layer is tested, analyzes packing effect, cannot realize and dynamically test envelope.In oilfield process, in order to understand the situation of reservoir, grasp related data, for next step exploitation provides scientific basis, need often oil-water well to be carried out to production test, after these test jobs all need to close a well in, be lowered to again special-purpose logger, the pressure of each layer of down-hole, temperature are carried out to the test of a couple of days, time-consuming, also affect the rate that drives a well simultaneously.
Summary of the invention
In order to solve in oil field operation, water injection well pulling allotment repeatedly, oil well are looked for packer working condition blindness in the operation of many times tubing string envelope cards of water blockoff, multiple-zone production, are understood these problem and shortage that downhole temperature pressure data need to carry out logging operation again.The invention provides intelligent actuator control system under the multifunctional well of a kind of myriametric wave and simulated pressure ripple coding-control, after packer combination, can have both water injection well and survey online tune, oil well one-trip string and survey and produce, look for that water blockoff, oil-water well multilayer are dynamically tested envelope, the continuous monitoring of oil-water well pressure and temp also can be uploaded to the multi-functional in the downhole intelligent actuator control system of one of ground receiving equipment, and can be used as flow string and use for a long time in down-hole.
technical scheme
The technical solution adopted for the present invention to solve the technical problems is: core of the present invention is to utilize myriametric wave penetration capacity strong, and the feature of simulated pressure ripple coding transmission distance, has solved the propagation problem of data in down-hole adverse circumstances.The present invention has downhole intelligent actuator and ground to control receiver two parts formation.Downhole intelligent actuator has urceolus, central tube, interior checkout gear, outer checkout gear, battery pack, contains data collection and analysis treatment circuit plate and software, signal reception and dispensing device, the actuating motor of electronic chip and comprises that extremely blocking up the various conventional water of chewing footpath such as (chewing footpath are 0mm) chews external member composition, these assemblies seal respectively and are integrated in a cavity, water is chewed external member the inside and outside control channel being communicated with, adjust the different uninterrupteds that passage has been controlled in footpath of chewing, there is different control codings in the different footpaths of chewing.Emitting-receiving system is because power consumption is larger, and at ordinary times in resting state, system is received and waken up after instruction, starts emitting-receiving system.Receiver is controlled on ground to be had main frame (including casing, power supply, circuit board, software) and forms for five parts of cable, the transceiver carrying by cable, myriametric wave simulated pressure signal generator, receiver of fetching data and online water filling is allocated.GCU to the control avenues of communication of downhole tool as required, is divided into cable and carries that wireless transmit reception antenna enters down-hole and myriametric wave analog signal generator, receiver is controlled two kinds at well head.Survey for oil well is produced, is looked for water blockoff, dynamically tests and seal these three operations, use ground to control the myriametric wave analog signal generator that receiver is controlled, pass through high pressure line, to down-hole, transmit the corresponding pressure waveform data encoding by software control, the intelligent actuator of each layer of down-hole under lower going-into-well before, all have separately and set one's own identity coding and signal instruction coding.Interior checkout gear is received after signal, analyzes, if belonged to, issues oneself order ，Ke command execution mechanism and carries out and neededly open or close or water is chewed and adjusted big or small action.Outer checkout gear detects pressure and the temperature of own layer position, and the storage of input circuit plate, as the foundation of analyzing.And can, according to the instruction receiving, carry out the corresponding program that feeds data back to ground receiving equipment.Water filling is surveyed online mediation downhole data and is uploaded, because of these two work data transmission quantities larger, need the myriametric wave transceiver carrying by cable, be lowered to the position approaching with downhole intelligent actuator, carry out wireless identification docking and exchanges data, transmission, executing data is uploaded to ground and receives memory device and adjust water and chew the required movements such as size, realize save time, laborsaving, reduce operating cost, improve the object of operating efficiency.
