Description
Technical field
The utility model relates to petroleum gas production with the combination of down-hole measure operating tool string, relates in particular to a kind of horizontal well, the multistage segmentation measure of high angle hole bore hole operating tool string.
Background technology
In the oil and gas exploitation process; To some hyposmosis or self natural energy is lower, output descends fast oil, gas well; After exploitation a period of time, generally all need carry out pointed layering, segmentation measure construction transformation, to improve the recovery ratio of reservoir to reservoir.Measures to reform comprises acidifying, pressure break, water filling etc.Existing down-hole segmentation measure operating tool string technology; Though can realize to a certain extent the horizontal well of straight well and cased hole completion is carried out segmentation measure operation; But also there are shortcomings such as sectional is few, operating cost height, especially when the horizontal well to barefoot completion carries out segmentation measure construction, also have certain difficulty; Be mainly reflected in: because the borehole wall is irregular, the multistage packing difficulty of horizontal bare hole section is big; Do not have corresponding anchor mechanism, the tubing string wriggling causes that easily the packer sealing inefficacy is difficult to reach subsection efect; Horizontal well track is complicated, factor such as tubing string self friction resistance in addition, and the measure operating tool string is lowered to the horizontal segment difficulty.
The utility model content
The purpose of the utility model is: a kind of horizontal well in segments measure operating tool string is provided; Be applicable to the horizontal well of straight well and cased hole completion; Also can be applicable to the horizontal well of barefoot completion; On the basis that satisfied safety is lowered to, the well section is carried out multi-stage mechanical segmentation packing, satisfy the needs of multiple measure construction technologies such as down-hole multilevel acidifying, pressure break, water filling.
The technical scheme that the utility model adopts is: horizontal well in segments measure operating tool string; Mainly form by oil pipe, hydraulic anchor, centralizer, sealing intubate, hanging packer, connection oil pipe, inflatable packer, pitching sliding sleeve, seat blocking seat, ball-and-seat and guide shoe; It is characterized in that: the upper end at guide shoe is connected with ball-and-seat; The upper end Connection Block blocking seat of ball-and-seat, the upper end of seat blocking seat connects 3～10 sliding sleeve packer groups; The upper end of sliding sleeve packer group connects oil pipe; The upper end that connects oil pipe is connected with hanging packer; The upper end of hanging packer is connected with the sealing intubate, is connected with centralizer on the sealing intubate, and the upper end of centralizer is connected with hydraulic anchor; The upper end of hydraulic anchor is connected with oil pipe, and oil pipe is until well head; Described sliding sleeve packer group is made up of inflatable packer, pitching sliding sleeve and centralizer; Be connected with a centralizer respectively at the two ends of inflatable packer; The other end at centralizer connects a pitching sliding sleeve, and the other end of pitching sliding sleeve is connected with the centralizer of next sliding sleeve packer group.
What described pitching sliding sleeve adopted is level pressure sliding sleeve or drillable ball injection sliding sleeve.
The beneficial effect of the utility model: horizontal well in segments measure operating tool string, adopt multistage sliding sleeve can realize the transformation of many wells of horizontal well section.Inflatable packer 7 has the sealing face length, and the pressure-bearing index is high, and it is effective that the borehole wall especially bore hole borehole wall is fitted, and is applicable to the well section of horizontal well, barefoot completion; Can effectively avoid fashionable under the tubing string, the packer that causes because of hydraulic action in the tubing string sets midway, and owing to be provided with unidirectional feeding device, has increased the reliability of tubing string.
Description of drawings
Fig. 1 is the utility model horizontal well in segments measure operating tool string structural representation.
Fig. 2 is the structural representation before the utility model horizontal well in segments measure operating tool string G.I.H seat envelope.
Among the figure, the 1-oil pipe, the 2-hydraulic anchor, the 3-centralizer, 4-seals intubate, the 5-hanging packer, 6-connects oil pipe, the 7-inflatable packer, 8-pitching sliding sleeve, 9-seat blocking seat, the 10-ball-and-seat, the 11-guide shoe, 12-sets oil pipe.
The specific embodiment
Embodiment 1: with a horizontal well in segments measure operating tool string is example, and the utility model is done further explain.
Consult Fig. 1.The utility model horizontal well in segments measure operating tool string mainly is made up of oil pipe 1, hydraulic anchor 2, centralizer 3, sealing intubate 4, hanging packer 5, connection oil pipe 6, inflatable packer 7, pitching sliding sleeve 8, seat blocking seat 9, ball-and-seat 10 and guide shoe 11.The parts that use entirely in the city field energy purchase.
Horizontal well in segments measure operating tool string is from bottom to top: be connected with a ball-and-seat 10 in the upper end of guide shoe 11, the upper end of ball-and-seat 10 connects a seat blocking seat 9, and the upper end of seat blocking seat 9 connects five sliding sleeve packer groups, can four stratum of packing.Sliding sleeve packer group is made up of an inflatable packer 7, a pitching sliding sleeve 8 and two centralizers 3; Be connected with a centralizer 3 respectively at the two ends of inflatable packer 7; The other end at centralizer 3 connects a drillable ball injection sliding sleeve 8, and the other end of drillable ball injection sliding sleeve 8 is connected with the centralizer 3 of next sliding sleeve packer group.The upper end of sliding sleeve packer group connects oil pipe 6; The upper end that connects oil pipe 6 is connected with a hanging packer 5; The upper end of hanging packer 5 is connected with sealing intubate 4, is connected with centralizer 3 on the sealing intubate 4, and the upper end of centralizer 3 is connected with hydraulic anchor 2; The upper end of hydraulic anchor 2 is connected with oil pipe 1, and oil pipe 1 is until well head.
Summary horizontal well in segments measure operating tool string operating principle.Consult Fig. 2.Should be according to five sliding sleeve packer groups of oil reservoir segmentation situation configuration.At first, connect the tubing string of giving up, the tubing string of giving up is that hanging packer 5 is to guide shoe 11 general names.Set oil pipe 12 in the connection of the top of the tubing string of giving up, utilization sets oil pipe 12 and will give up the tubing string G.I.H to design attitude.Secondly, drop into minor diameter low-density ball sealer, when ball sealer arrives seat blocking seat 9; The tubing string internal pressure raises, and hanging packer 5 sets with inflatable packer 7, after waiting to set completion; Continue to improve the tubing string internal pressure, the tubing string of giving up just can be realized effective packing that the well section is carried out.Consult Fig. 1.Then, take out and set oil pipe 12, be lowered to sealing intubate 4 with top, sealing intubate 4 and hanging packer 5 sealed butt joint.Rising tubing string internal pressure, hydraulic anchor 2 are carried out grappling to the measure operating tool string under the effect of measure operating tool string inside and outside differential pressure, continue rising tubing string internal pressure, and pitching sliding sleeve 8 is opened, and carry out first section measure construction operation; In the time of need carrying out the measure construction operation to second section; Just can drop into major diameter low-density ball sealer slightly, after this low-density ball sealer arrives pairing drillable ball injection sliding sleeve 8, rising tubing string internal pressure; Open drillable ball injection sliding sleeve 8; Can carry out second section measure construction operation, and the like, just can accomplish third and fourth, the measure construction operation of sections such as five.After operation is accomplished, take out the measure operating tool string, be lowered to that other corresponding tubing strings can be produced or operation such as test.
