Abstract
The invention relates to the oil field oil production engineering technology field, and belongs to an intelligent injection allocation testing device of a water injection well. The intelligent injection allocation testing device of the water injection well mainly solves the problems that the existing separated layer water injection equipment has high testing work load, long allocation period and low water injection qualification rate in the construction process. The intelligent injection allocation testing device of the water injection well is composed of an upper joint 1, an upper connecting sleeve 2, a guiding body 3, a non-contact electric energy conversion system 4, a central pipe 5, an automatic control circuit board 6, a main body 7, a diversion body 8, a flow control valve 9, a data collection system 10, a lower connecting sleeve 11 and a lower joint 12, wherein, the non-contact electric energy conversion system 4 is connected with the central pipe 5 in a locating way, and the automatic control circuit board 6 is bonded with the central pipe 5. The device adopts mechanical-electrical integration design, saves a great quantity of conventional production test cost, controls the opening degree of the flow control valve and has the advantage of automatic water distribution.

A, at first the Intelligent water injection tubing string is set in the down-hole, simultaneously corresponding each the injection allocation stratum of each intelligent allocation testing device, the at this moment automatic control circuit board 6 in the intelligent allocation testing device, data collecting system 10 and the mutual co-ordination of flow control valve 9 beginnings;
C, when needs are revised the injection allocation scheme, be lowered into allocation instrument in the intelligent allocation testing device of appointment by power cable, carry out Wireless Data Transmission with the automatic control circuit board 6 in the intelligent allocation testing device, simultaneously the injection allocation scheme of automatic control circuit board 6 is allocated;
After d, allotment are finished, trip out allocation instrument, intelligent allocation testing device is then proceeded monitoring and the automatic governing of flow in the down-hole, realize the comprehensive automation of water injection technology.
