Abstract
The microcomputer controlled packer is used in oil and gas field downhole multistage layering operation. The rubber cylinder moving ring mainly comprises a rubber cylinder, a micro motor, a micro computer controller, a rotating pull rod, a pull rod supporting sleeve, a rubber cylinder moving ring sliding groove, a rubber cylinder moving ring, a central pipe, a central connector of the rubber cylinder moving ring, a rib plate of the rubber cylinder moving ring, a sealing ring of the rubber cylinder moving ring and a limiting sleeve of the rubber cylinder. The packer firstly carries out the program setting of the packer setting and the unsealing actions on the ground to a microcomputer controller, the packer is controlled according to the time setting, an upper driving motor is set to rotate clockwise, a lower driving motor is set to rotate anticlockwise, an up-down moving ring is driven to move towards two ends through threaded connection, and an upper rubber sleeve and a lower rubber sleeve are compressed to be set; otherwise, the packer is unsealed. The packer setting or unsetting reliability and operability are improved, and the current situations of complex setting and difficult unsetting of the conventional packer are simplified. Can multistage 10 ~ 15 grades of using, the multistage borehole operation of 15 ~ 20 sections of present long horizontal well section can be realized to a string, improves borehole operation efficiency.
Description
Technical field
The present invention relates to be used in the oilfield operation process downhole tool of oil-separating layer, particularly be applicable to the packer of oil gas well down-hole multilevel stratified operation, is a kind of micro computer controlled standard packer.The downhole tool that in the oilfield operation process, is used for oil-separating layer is applicable to oil gas well down-hole multilevel stratified operation.
Background technology
At present, employed fluid pressure type, compression, inflatable packer structure are similar, by packing element, rubber cylinder pressing cap, go up lower contact and slips is formed; Slips struts earlier and is stuck on the internal surface of sleeve pipe when setting, then through suppressing in the oil pipe or tubing string is transferred compression and driven rubber cylinder pressing cap and move the expansion of compression packing element; Realize packer setting, set the construction complicacy, the site operation risk is high; And the deblocking difficulty is prone to cause down-hole accident; Particularly in horizontal well, packer is at net horizontal section, and slips is stuck in internal surface of sleeve pipe, and the deblocking difficulty is bigger, risk is higher; Fluid pressure type, compression, expanding can not be used in multistage connection, can't realize the requirement of horizontal well one-trip string multistage operation.Though the multistage use of self-packing packer ability, progression are three grades at most, and packing element and casing wall friction in the process of going into the well, and cause the packing element wearing and tearing, and sealing performance reduces.
Along with the development of oil-gas field development technology, directional well individual layer exploitation again turns to multiple-zone production, and the short again net horizontal section (2～3 sections) of horizontal well turns to long net horizontal section (8～10,15～20 sections); Need a kind ofly can multistagely to use, the reliable packer of sealing; Each interval sealed clamping cleat is opened, carried out laminated distributor under well, the operation of segmentation card envelope, reduce the operation number of times; Reduce operating risk, improve oil gas well underground work efficient.
Chinese patent publication number: CN201513153U provides a kind of " support rise the electronic packer of envelope formula ", comprises the packer cylindrical shell that upper shell and lower shell are formed, and is provided with packing element in the outside of cylindrical shell; Upper end at upper shell is connected to motor casing, and motor is fixed on the inboard of motor casing, and the output shaft of the motor main shaft inboard with being located at cylindrical shell joins; Between upper shell and lower shell, be positioned at the packing element inboard and be provided with at least two back-up blocks; Back-up block evenly distributes on circumference; Each back-up block is connected with an end rotating shaft of trace; The other end of trace is connected with the screw rotating shaft, nut sleeve be contained on the said main shaft and with main shaft between for being threaded.Have that overall structure is simple, operation easily, time saving and energy saving, advantage such as running cost is low.
Chinese patent publication number: CN2185319 provides a kind of " the electronic compression packer in down-hole ", is a kind of electronic packing device that is suitable for oil well downhole packing oil reservoir.Structure has power pack, control section, drive part, deceleration part, the envelope that rises part; Connect envelope part, deblocking partly constitutes; Interior siphunculus is equipped with at the packer middle part; The envelope part of rising has power transmission shaft, outside and is equipped with between outer tube, outer tube and the axle removable pin is housed, and packing element is contained in the outside packing element of outer tube top and is equipped with that top board, bottom are equipped with down, power transmission shaft links to each other with the reducing gear of deceleration part; The deblocking part is made up of spring, spring base, clamp nut, functional head.
