Abstract
The invention relates to the technical field of oil production engineering in the oil field, and belongs to an intelligent injection allocation process of a water injection well. The invention is designed for solving the disadvantages that an adjustable stopper needs to be thrown and caught and adjusted repeatedly in the testing and the testing work load is high. In the invention, an intelligent water distribution device 7 is provided with an automatic control system, a data acquisition system and an automatic regulating valve system, and meanwhile, the intelligent water distribution device 7 can automatically collect the flow rate, temperature and pressure data in each intelligent injection ground layer through the data acquisition system when working under the ground, and the data is fed back to the automatic control system; the automatic regulating valve adjusts the current flow rate, so as to lead the flow rate to meet the injection allocation scheme. The intelligent injection allocation process of the water injection well has advantages that various characteristic parameters of the underground water injection well can be dynamically monitored and the expenses of a great quantity of conventional production tests are saved.
Description
Technical field:
The present invention relates to the oil extraction in oil field field of engineering technology, belong to a kind of intelligent injection allocation process of water injection well.
Background technology:
Be in the main body test technology at tester at present, in eccentric injection mandrel, preset dead mouthpiece during conventional tubing string operation and finish setting packer in going into the well, set and pull dead mouthpiece out after finishing, and then each layer dropped into respectively adjustable blanking plug carry out to test envelope and follow-up flow or pressure test after the water filling, increase along with water injection well, the test job amount also increases substantially thereupon, and existing troop can't satisfy.In order to shorten test period, reduce workload, improve the water filling qualification rate, realize the comprehensive automation that the water filling survey is transferred, invented intelligent injection allocation process of water injection well.
Summary of the invention:
The objective of the invention is to realize a kind of each interval water filling state of down-hole to be carried out continuous monitoring, and make in real time surveying according to monitoring result and transfer response, reduce the test job amount and will survey the intelligent injection allocation process of water injection well that the accent cycle foreshortens to minimum.
The present invention is by realizing with lower device: it is comprised of computer, power cable, main control system, oil pipe, allocation instrument, packer, intelligent watering device and sleeve pipe; Wherein the power cable upper end connects main control system, the lower end links to each other with allocation instrument, and intelligent allocation instrument is lowered in the intelligent watering device, and oil pipe and packer are by screwed connection, packer and intelligent watering device are by screwed connection, and there is sleeve pipe the outside of oil pipe, packer and intelligent watering device; This technique realizes by following steps:
A, at first oil pipe, packer, intelligent watering device are connected be lowered in the sleeve pipe, corresponding each the injection allocation stratum of each intelligent watering device of while, packer is set in sleeve pipe, and at this moment the automatic control system in the intelligent watering device, data collecting system and automatic regulating valve system begin mutual co-ordination;
Data collecting system in b, the intelligent watering device gathers flow, temperature and the pressure data on each injection allocation stratum automatically, and with data feedback to automatic control system, automatic control system is checked present flow rate by the injection allocation scheme, if present flow rate meets the injection allocation scheme then continues image data, if do not meet, then automatic regulating valve is sent signal, automatic regulating valve is adjusted present flow rate, makes it satisfy the injection allocation scheme;
C, when needs are revised the injection allocation scheme, be lowered into allocation instrument in the intelligent watering device of appointment by power cable, the power cable upper end connects main control system and computer, allocation instrument is controlled by computer with manual type, can carry out Wireless Data Transmission between allocation instrument and the intelligent watering device, simultaneously the injection allocation scheme of intelligent watering device be allocated;
After d, allotment are finished, trip out allocation instrument, the intelligent watering device then continues automatically to carry out the monitoring of flow and to the automatic governing of flow, realizes the comprehensive automation of water injection technology in the down-hole.
Compared with the prior art the present invention has following advantage:
Because the present invention adopts Electromechanical Design, by various sensors are placed on the down-hole for a long time, can carry out to each characterisitic parameter of down-hole the long-term dynamics monitoring.Not only can avoid a large amount of production tests, also avoid the interference of test to normal production simultaneously, save a large amount of conventional production test expenses.
