Description

Water injection well downhole intelligent control regulating and measuring system
Technical field:
The present invention relates to the used water filling test macro of water injection well in the oil recovery field, oil field, especially water injection well downhole intelligent control regulating and measuring system.
Background technology:
Along with Oilfield developing, strata pressure successively decreases, and in order to keep strata pressure, the oil field generally adopts flood pattern to improve the pressure on stratum, thereby improves recovery ratio.Present separated-zone water infection oil field 665 type layering water distribution tubing string and supporting measuring and adjusting systems thereof that always follow conventional lines from the water distribution tubing string, can't be realized simultaneously on this tubing string that conventional diminishing method is surveyed to be in harmonious proportion the individual layer of the pressure water yield and to survey and transfer the tubing string function singleness; From regulating and measuring system, this technology employing pulling water distribution plug, replacing water distribution mouth size wherein realizes the allotment of zonal flow rate, because the water distribution mouth is divided by rank, gets pulling blanking plug repeatedly, so discontinuous, can't satisfy the requirement of water yield allotment fully.Limited by measuring and adjusting system, also there is allocation process in former water distribution system and surveys the accent process asynchronous, and survey adjusting data and allotment result can't obtain in ground synchronous, survey problems such as the accent process is loaded down with trivial details, transfer survey precision and operating efficiency all lower.
Summary of the invention:
Existing eccentric layering water distribution system is surveyed accent efficient and the low deficiency of precision surveyed in accent in order to overcome, the invention provides a kind of water injection well downhole intelligent control regulating and measuring system, this water injection well downhole intelligent control regulating and measuring system is not only surveyed and is transferred efficient and transfer survey precision height, and can also carry out individual layer press water measurement accent and can adopt conventional method to test envelope, conventional diminishing method survey accent, realized that the electronic accent in down-hole of each interval flow of separate water injection well is surveyed, survey accent process ground is monitored in real time, every survey is raised wages, and the ground synchronous of expecting data is enrolled.
Technical scheme of the present invention is: this water injection well downhole intelligent control regulating and measuring system comprises multi-functional eccentric injection mandrel, throw in catcher, continuous adjustable blanking plug, electronic measurement and adjustment instrument and the ground monitoring instrument that is connected on the water injection string.
The beneficial effect that the present invention has is: this water injection well downhole intelligent control regulating and measuring system is owing to adopted such scheme, mainly on multifunctional ligand hydrophone seating nipple, opened the side direction passageway bridge, in continuous adjustable blanking plug master tube, water nozzle still and water nozzle moving plate have been increased, the ground monitoring instrument adopts sonar technique to control electronic measurement and adjustment instrument, electronic measurement and adjustment instrument control water nozzle moving plate changes the captured area of weep hole, realizes electronic accent survey.Compare with conventional eccentric center water-distributing water distribution system, the downhole system tubing string can adopt usual manner to test envelope, diminishing method is surveyed and transferred, and can realize that again the survey of the individual layer pressure water yield is transferred.Survey in the water yield that the electronic accent in down-hole of having realized each interval flow on the key survey method is surveyed, ground is monitored in real time, the downhole measurement adjusting data information is enrolled synchronously, the direct transmission of data-signal, with conventional eccentric center water-distributing system essential distinction is arranged in the system.It is 5 days that the average individual well of conventional waterflooding system is surveyed between timing, and this system's individual well was surveyed between timing only 1 day, increased work efficiency 5 times.Simultaneously, because continuous adjustable blanking plug water nozzle moving plate control discharge area continuity is better, improve and survey the precision of transferring, in addition, use this technology and realize going into the well once, survey the full well water amount of transferring, reduce conventional system pulling repeatedly, removed the instrument workload, reduce labour intensity more than 5 times, reduced cost for oil production, have to such an extent that apply.
