Abstract
A fast sand filling tubular column comprises a steel wire rope, a safety joint, a sleeve tube, a sand containing tubular column, a liquid suction device and a release device. The lower portion of the steel wire rope is connected with the upper portion of the safety joint, the lower portion of the safety joint is connected with the upper portion of the sand containing tubular column, the liquid suction device is arranged on the lower portion of the sand containing tubular column, the liquid suction device is in fit sealing with the sleeve tube, the release device is arranged on the lower portion of the liquid suction device, the safety joint, the sand filling tubular column, the liquid suction device and the release device are lowered in the position above a well bottom in the sleeve tube along with the steel wire rope, well filling sand is contained in the sand containing tubular column, all sand filling tools are lowered in through the steel wire rope, and are fast to lower in and out, displacement liquid does not need to be injected in, the construction process is simple, the designed liquid suction device can prevent the sand from being accumulated and forming a sand bridge, engineering accidents are reduced, therefore, the fast sand filling tubular column can fill the well bottom with the sand fast, easily and conveniently, the operation cost can be saved, the labor intensity of workers can be relieved, and obvious economic benefits and social benefits are achieved.
Description
Technical field
The utility model is the assorted column jacket that oil-water well workover treatment is used, and is a kind of back-up sand tubing string fast.
Background technology
When oil-water well needs long-time shutoff bottom layer position, generally adopt the way of cementing plug to realize, will be to back-up sand in well before cementing plug, to reduce the thickness of cement plug, minimizing difficulty of construction and later recycling are by well filling section.At present back-up sand method be by under back-up sand tubing string to shaft bottom, in back-up sand tubing string, pour sand into, then enter to squeeze into displacement fluid to well, make the sand in back-up sand tubing string fall into shaft bottom.Due to sand grains diameter difference, the sand falling speed difference of pouring into from well head easily forms sand bridge in pit shaft, and construction cannot be carried out.And the flow chart of this method is many, operate cumbersomely, the engineering time is long, and operating cost is high, will sand pipe laying post if any operate miss, cause Important Project accident.
Summary of the invention
The purpose of this utility model is a kind of back-up sand tubing string fast of design, and fast and convenient fills out shaft bottom by sand, reduces working procedure, avoids occurring engineering accident.
The purpose of this utility model is achieved in that and comprises wire rope, safety joint, sleeve pipe, sand loading tubing string, pumping device, releasing device, the bottom of wire rope is connected with the top of safety joint, the bottom of safety joint is connected with the top of sand loading tubing string, pumping device is installed in the bottom of sand loading tubing string, pumping device and sleeve pipe fitted seal, releasing device is installed in the bottom of pumping device, safety joint, sand loading tubing string, pumping device, releasing device are lowered on the shaft bottom in sleeve pipe with wire rope, have well filling sand in sand loading tubing string.
The beneficial effects of the utility model are: be lowered to whole sand filling tools with wire rope, sand filling tool removes soon, do not need to squeeze into displacement fluid, working procedure is simple, and the pumping device of design can be avoided sand to pile up and form sand bridge, reduce engineering accident, therefore, what the utility model can be fast and convenient inserts shaft bottom by sand, can save operating cost, alleviate labor strength, there is significant economic benefit and social benefit.
Brief description of the drawings
Accompanying drawing is the assembling drawing of the utility model embodiment.
Detailed description of the invention
Below in conjunction with accompanying drawing, embodiment of the present utility model is described.
2. as seen from the figure, embodiment of the present utility model comprises wire rope 1, safety joint 2, sleeve pipe 3, sand loading tubing string 4, pumping device 5, releasing device 6, the bottom of wire rope 1 is connected with the top of safety joint 2, the bottom of safety joint 2 is connected with the top of sand loading tubing string 4, pumping device 5 is installed in the bottom of sand loading tubing string 4, pumping device 5 and sleeve pipe 3 fitted seal, pumping device 5 is mainly made up of the parts of unidirectional leather cup and fixing unidirectional leather cup, the horn mouth of unidirectional leather cup upwards, unidirectional leather cup is close to sleeve pipe 3, can change with the diameter of sleeve pipe 3, can in the sleeve pipe that has distortion, be lowered to, releasing device 6 is installed in the bottom of pumping device 5, safety joint 2, sand loading tubing string 4, pumping device 5, releasing device 6 is lowered on the shaft bottom 7 in sleeve pipe 3 with wire rope 1, in sand loading tubing string 4, there is well filling sand, the volume of well filling sand is determined by the internal diameter of back-up sand thickness and sleeve pipe 3.
When safety joint 2, sand loading tubing string 4, pumping device 5, releasing device 6 are lowered on the shaft bottom 7 in sleeve pipe 3 with wire rope 1, releasing device 6 collides with shaft bottom 7, the switch of releasing device 6 is opened, sand in sand loading tubing string 4 falls and is filled into shaft bottom, then draw high wire rope 1, make sand loading tubing string 4, pumping device 5, releasing device 6 leave sand face, in the time drawing high pumping device 5, pumping device 5 is twitched liquid in well, while making liquid flow, break up sand redistribution, avoid piling up formation sand bridge.
The effect of safety joint 2 is to carry on exerting oneself after sand loading tubing string 4 is stuck, and it is disconnected from safety joint 2, ensures that wire rope 1 is not pulled off, and is convenient to later stage fishing.
