Abstract
The invention relates to an intelligent injection allocation testing device of a water injection well, relating to the technical field of oil-well testing. The invention 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, a control circuit board 6, a main body 7, a diversion body 8, a flow control valve 9, a lower connecting sleeve 10 and a lower joint 11, wherein, the non-contact electric energy conversion system 4 is connected with the central pipe 5 in a locating way, and the control circuit board 6 is connected with the central pipe 5 in a locating way. 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.
Description
Technical field:
The present invention relates to the oilfield test technical field, belong to a kind of intelligent injection allocation testing device of water injection well.
Background technology:
Be in the main body test technology at tester at present, along with the increase of water injection well, the test job amount also increases substantially thereupon, and existing troop can't satisfy.The water filling qualification rate is subjected to multifactor impacts such as strata pressure, interwell communication, and situation complexity, variation are shortened the allotment cycle and can only be improved the water filling qualification rate to a certain extent, and the test job amount is multiplied soon.This technology can realize the comprehensive automation of water filling survey accent, shortens test period, reduces workload, improves the water filling qualification rate, for the surely oily control water in oil field provides strong technical support, will produce remarkable economic efficiency and social benefit.
Summary of the invention:
The invention provides a kind of comprehensive automation that can realize that the water filling survey is transferred, shorten test period, reduce workload, improve the intelligent injection allocation testing device of water injection well of water filling qualification rate.
Technical scheme of the present invention is: this water injection well intelligence water dispensing apparatus is by top connection, upper joint sleeve, guide way, the non-contact electric energy converting system, central tube, control circuit board, main body, baffle, flow control valve, lower joint sleeve and lower contact are formed, wherein top connection and upper joint sleeve are by being threaded, guide way and central tube by be inserted into after being located by connecting in the upper joint sleeve with upper joint sleeve by being threaded, non-contact electric energy converting system and central tube are by being located by connecting, control circuit board and central tube are by being located by connecting, main body upper end and upper joint sleeve are by being threaded, lower end and lower joint sleeve are by being threaded, flow control valve passes baffle and main body by being located by connecting, and lower joint sleeve and lower contact are by being threaded.
Compared with the prior art the present invention has following beneficial effect:
Owing to adopt Electromechanical Design,, can carry out the long-term dynamics monitoring to each characterisitic parameter of down-hole by various sensors are placed on the down-hole for a long time.Help to judge the various situations of down-hole on the one hand, can avoid a large amount of production tests on the other hand, also avoid the interference of test simultaneously, save great amount of conventional production test expense ordinary production, and can control the size of flow control valve aperture, have the advantage of automatic distribution water.
Description of drawings:
Accompanying drawing 1 is a structural representation of the present invention;
1-top connection among the figure, 2-upper joint sleeve, 3-guide way, 4-non-contact electric energy converting system, 5-central tube, 6-control circuit board, 7-main body, 8-baffle, 9-flow control valve, 10-lower joint sleeve, 11-lower contact.
The specific embodiment:
The invention will be further described below in conjunction with accompanying drawing: this water injection well intelligence water dispensing apparatus is by top connection 1, upper joint sleeve 2, guide way 3, non-contact electric energy converting system 4, central tube 5, control circuit board 6, main body 7, baffle 8, flow control valve 9, lower joint sleeve 10 and lower contact 11 are formed, wherein top connection 1 and upper joint sleeve 2 are by being threaded, guide way 3 and central tube 5 by be inserted into after being located by connecting in the upper joint sleeve 2 with upper joint sleeve 2 by being threaded, non-contact electric energy converting system 4 and central tube 5 are by being located by connecting, control circuit board 6 and central tube 5 are by being located by connecting, main body 7 upper ends and upper joint sleeve 2 are by being threaded, lower end and lower joint sleeve 10 are by being threaded, flow control valve 9 passes baffle 8 and main body 7 by being located by connecting, and lower joint sleeve 10 and lower contact 11 are by being threaded.
During on-the-spot the use, at first intelligent water injection string is set in the down-hole, be lowered to front controller by power cable, front controller positions by the guide way in this device 3, and enters into central tube 5.
Downhole flow control valve 9 is monitored in real time and controlled with computer on ground, can carry the tubing string load, carry out the collection of data such as flow, temperature, pressure and battery status, and can be this device charging by non-contact electric energy converting system 4.Adopt the mode of ground directly-reading that the water filling interval is carried out artificial flow allocating, can reclaim historical record simultaneously.Can revise automatic allotment regulation and control parameter after finishing allotment, trip out front controller then, allocate by the flow of 9 pairs of these intervals of flow control valve according to the requirement of injection allocation scheme, realize the comprehensive automation of water injection technology by the control circuit board 6 of this device.
