Abstract
The utility model discloses a sectionalized water-exploration testing pipe column of a casing well-completion horizontal well, which is applied to production process of the horizontal well. A guide screwed plug which is connected to the internal part of a horizontal-section casing of the horizontal well from bottom to top; the upper part of the guide screwed plug is connected with at least three water-exploration switches through a coupling chamfer oil pipe; a packer is connected between the adjacent two water-exploration switches through the coupling chamfer oil pipe; the upper part of the water-exploration switch at the top part is connected with a safety connector through the oil pipe. The upper part of the safety connector is connected with a bridging oil-extraction pump; the upper part of the bridging oil-extraction pump is connected with the oil pipe to the well opening. The benefits of the sectionalized water-exploration testing pipe column of the casing well-completion horizontal well are as follows: the water-exploration testing is integrated with a production part; a pipe column can complete the sectionalized water-exploration testing and the producing for the casing well-completion horizontal well. Oil pumping adopts the bridging oil-extraction pump so as to lead load under the pump to be bore by a bridging plug in; a pump cylinder does not bear load, therefore, the normal pumping of an oil-pumping pump is ensured. The packing between various perforation sections adopts a self-packing cup-type packer, therefore, the pipe column does not need to be moved or a packer seat does not need to be pressed during seat packing.
Description
Technical field
The utility model relates to that a kind of horizontal well is used packer card layer in process of production, electric-controlled switch carries out sectionalization test water detection at down-hole switch etc., specifically, is a kind of novel cased hole completion horizontal well in segments water detection test technology tubing string.
Background technology
At present, existing oil well searching pipe column only is applicable to straight well, directional well.
Oil well method zonal testing water detection process pipe string has two classes at present.
One class is the back throwing valve tubing string of production test one, one-trip string can be finished the water detection test, throws valve+telescoping tube+one-level packer+one-level water detection tester+secondary packer+secondary water detection tester+three grades of packer+three grade water detection tester+level Four packer+level Four water detection tester+plugs by tubing pump+back and constitutes.This class tubing string adopts fluid pressure type ZPY341 packer, back to throw faner apparatus and tubing pump, need suppress behind the following intact tubing string to set.If be used for horizontal well water detection, multistage packing can't be verified in the horizontal segment sealing, tests back deblocking difficulty and easily causes down-hole accident, and load causes the tubing pump operational failure than conference under the pump simultaneously.
Another kind ofly be made up of pumping pipe string and test string two parts, need down twice tubing string to finish, beat hydraulic pressure from oil pipe behind the following intact operating tool string to make packer setting, and then pitching is to back-off sub, pressurization realizes that tubing string gives up again.Trip out and be lowered to pump behind the operating tool string and take out flow string, oil well drops into ordinary production.Test string is by giving up, look for Packer for blocking water, switch and setting ball seat to constitute, and the card layer adopts a Y341 packer, is used for net horizontal section and can occurs multistage packing sealing equally and can't verify the deblocking difficulty.
The utility model content
The purpose of this utility model provides a kind of cased hole completion horizontal well in segments water detection test string, and one-trip string is finished cased hole completion horizontal well in segments production dynamic test, finds the horizontal well water exit end, for the measure of oil well water-control oil-increasing provides foundation.
The technical solution adopted in the utility model is: cased hole completion horizontal well in segments water detection test string, form by guiding plug, box cupling chamfering oil pipe, water detection switch, packer, safety joint, gap bridge oil extraction pump and oil pipe.It is characterized in that: in the horizontal segment sleeve pipe of horizontal well, be connected with the guiding plug from bottom to top, the top of guiding plug is connected with three water detection switches at least by box cupling chamfering oil pipe, connect packer by box cupling chamfering oil pipe between adjacent two water detection switches, be connected with safety joint by oil pipe on the water detection switch top at top.The top of safety joint is connected with the gap bridge oil extraction pump, and the top of gap bridge oil extraction pump connects oil pipe until well head.
The quantity of described water detection switch is 3～8, and the quantity of packer is 2～7.
A water detection switch all is equipped with at the perforated interval of horizontal well in the position of described water detection switch on each perforated interval.
Described packer is a cup packer.
One-trip string can be finished horizontal well in segments water detection test, and behind the following intact tubing string, cup packer directly leaves each perforated interval card, need not suppress the seat envelope, starts the production test of pumping continuously of ground oil pumper.Gap bridge oil extraction pump bottom load is by the plug-in carrying of passing a bridge of gap bridge oil extraction pump, and the pump barrel of gap bridge oil extraction pump is not subjected to load.
Before going into the well, tubing string according to the testing time of each section corresponding water detection switch acquisition time is set on ground.Well operations is finished under the searching pipe column, the water detection switch of correspondence is in opening during first section water detection, other is a closed condition, first section output liquid is pumped into ground by the gap bridge oil extraction pump, thereby obtain individual layer production fluid amount, data such as moisture, close to the fixed time derailing switch, first section water detection finishes.Second section derailing switch opened on schedule automatically, runs to the predetermined shut-in time to close the creation data that this time period admission is second section automatically.Can obtain each section production fluid amount, data such as moisture successively respectively.
The beneficial effects of the utility model: cased hole completion horizontal well in segments water detection test string, the water detection test is divided into one with production department, and one-trip string can be finished cased hole completion horizontal well in segments water detection test and produce.Oil pumping adopts the gap bridge oil extraction pump to make that load is by the plug-in carrying of passing a bridge under the pump, and pump barrel is not subjected to load, has guaranteed the normal pumping of oil well pump.The cup packer of self-styled form is adopted in packing between each perforated interval, need not move tubing string during the seat envelope or suppress the seat envelope.Each perforated interval correspondence is provided with derailing switch can carry out switch according to the instruction that ground in advance is provided with, and need not realize that the down-hole changes layer by Ground Operation.
