Description
Technical field
The utility model relates to the oil field development technical field, and the particularly down-hole special tool that uses of separated-zone water infection oil field construction is a kind ofly can realize the down-hole water distribution of seperated layer water injection and the seating nipple of monitoring.
Background technology
Separate zone waterflooding technology can effectively develop oil fields, continue aspects such as stable high yield, raising waterflood recovery efficiency factor and obtain remarkable effect.Realizing effective water filling, improve the oil recovery effect of high-water-cut oil-producing well, is the inevitable choice of latter period of oilfield development.The separate zone waterflooding technology of China level that is in a leading position in the world.
The separate zone waterflooding technology in domestic oil field is leading with the water injection technology of Daqing oil field, Shengli Oil Field and Jilin Oil Field.At present, domestic separated-zone water infection oil field tubing string is divided into two classes, and a kind of is concentric dispensing method, and a kind of is eccentric dispensing method.The tubing string that early stage concentric dispensing method adopts is surveyed timing need be with the whole taking-up of tubing string, and this technical operation workload is big, the expense height.On this basis, developed into concentric integrated seperated layer water injection again, be lowered to the same pacing accent that the measurement and adjustment instrument device is realized two intervals, but can only realize the survey accent of four intervals at most, and survey accent instrument does not have versatility, development specially.Another kind is the eccentric dispensing method of extensive use, and eccentric dispensing separate layer water injection string is eccentric separate injection tubing string.Common eccentric dispensing can be under the fixed tubular column condition realize the water nozzle allotment of any one-level by wire Launching and Bailing, but when certain layer tested, and the passage of can plying in the centre exerts an influence to the normal injection of other layers.In order to address this problem, Daqing Oilfield Company has been invented the bridge-type eccentric separate layer water injection string on common eccentric water injection string basis, can realize the allotment of any one-level water nozzle equally.Simultaneously, can also test any one deck separately, the normal injection to other layers does not exert an influence.
On bridge-type eccentric separate layer water injection string architecture basics, invented efficient survey conditioning technology.Be lowered to test and the allotment that the measurement and adjustment instrument device is realized each interval of down-hole by steel wire or cable, but this tubular column structure can't be realized the real-time monitoring of each layer parameter.Can not realize simultaneously transferring, be difficult to avoid interlayer interference to transfer the influence that causes surveying with pacing.
Under this background, press for a kind of novel layered water injection pipe rod structure of invention, the advantage that can keep existing eccentric separate injection tubing string to be had is such as carrying out the pulling operation to injection well downhole flow regulator.Simultaneously, can realize the automatic control of seperated layer water injection again, monitor in real time and transfer, realize more intelligentized seperated layer water injection with pacing.
The Chinese patent publication number: 2592865, a kind of in providing " anti-corrosion anti-scale rust-proof type injection well downhole flow regulator seating nipple ".It is built-in fixing by lining that main body inner wall has groove.Avoid the corrosion generation and the precipitated scale of alkali acid ion in the injecting process to destroy or stop up the test through hole, thereby water injection string was lost efficacy, reduced and done over again, greatly reduce labour intensity.Publication number: 2756824, a kind of " eccentric injection mandrel " is provided.On the hole wall between the centre bore of the eccentric orfice of seating nipple and seating nipple, have an inclined hole that communicates with centre bore; Seating nipple by screw in housing.This eccentric injection mandrel not only connectivity robustness is good, and blanking plug is difficult for blocking stifled.
The utility model content
The purpose of this utility model is: the seating nipple of water distribution of a kind of down-hole and monitoring is provided, and the pulling operation process is realized accurately location and guiding control, provides enough eccentric space to hold large diameter injection well downhole flow regulator in the confined space, improves the pulling success rate.
The technical solution adopted in the utility model is: the seating nipple of down-hole water distribution and monitoring, mainly form by tubing coupling, end face guide cam, last eccentric joint, last guide holder, housing, spring fastening, lower contact, eccentric mounting, following guide holder, steady pin and retainer spring, a tubing coupling has been threaded on the top of last eccentric joint, it is characterized in that: the lower end at last eccentric joint is connected with cylindrical shell, lower end at housing is connected with eccentric mounting, is connected with lower contact in the lower end of eccentric mounting.An end face guide cam is arranged in last eccentric joint, guide holder on the top in housing has, following guide holder is arranged at the bottom in housing; At last guide holder and following guide holder is the cylinder bodily form, between last guide holder and following guide holder a spring fastening is arranged.Last guide holder, following guide holder and spring fastening have U type gathering sill, and one of effect of U type gathering sill can make liquid circulate from top to bottom.On the outer wall of spring fastening retainer spring is arranged, retainer spring is a ring like steel wire, at the two ends of retainer spring crotch is arranged.On spring fastening, be symmetrically fixed with two steady pins, on the outer wall of steady pin, be with the annular brace cover.Retainer spring is fixed on the arc surface outside of spring fastening by screw.Tubing coupling, end face guide cam, last guide holder, spring fastening, following guide holder eccentric mounting and lower contact have a concentric holes.Axial eccentric mounting hole is arranged on eccentric mounting, and there is the inclined hole with concentric holes UNICOM lower end, eccentric mounting hole.
The beneficial effects of the utility model: the seating nipple of water distribution of the utility model down-hole and monitoring, adopt eccentric design, for being installed, large diameter injection well downhole flow regulator provides the space, and simplify and drop into and salvage operation.The latch lock locking structure is simple and reliable, can realize the accurate location and reliable release of major diameter injection well downhole flow regulator.
