Description
Technical field
Packer, particularly expanding sealing sleeve of internal pipe string tool external packer when the utility model relates to petroleum oil well completion field middle sleeve external packer and sets.
Background technology
When utilizing external casing packer to set, adopt the ball seat pitching to build the pressure usually, reach the bloated envelope operation of external casing packer.There is following drawback like this: the one, be unfavorable for the accurate control of down-hole operation pressure; The 2nd, the multistage external casing packer construction operation of incompatibility; The 3rd, be unfavorable for the bloated envelope of the external packer of pipe validity check of construction operation; The 4th, utilize the stage cementing device pitching to build the pressure and have risk.The operation of conventional expanding sealing sleeve external packer of pipe is to utilize pitching to build the pressure to expand that (pressure 8~10MPa) continues to build the pressure greater than 15MPa the tube sealing external packer then, and stage cementing device is opened, the above well section of cementing sealing stage cementing device.
Summary of the invention
The purpose of this utility model provides the expanding sealing sleeve of internal pipe string tool external packer, so that the bruising when solving the operation of expanding sealing sleeve external packer of pipe is controlled inaccuracy, can't be tested the problem of scurrying of testing of sealing, effectively improve external casing packer and set success rate, and can be in time to setting effect evaluation, this packer has stable performance, little, the high reliability features of risk simultaneously.
The technical solution of the utility model is: the expanding sealing sleeve of internal pipe string tool external packer, it is characterized in that: it comprises: go up packer in the expanding pipe, constant pressure valve, packer in the following expanding pipe, the horizontal well ball seat, the oil pipe of guide shoe and connector Φ 73, oil pipe by Φ 73 between the interior packer of interior packer of last expanding pipe and following expanding pipe is connected with constant pressure valve, packer is connected with the horizontal well ball seat by the oil pipe of Φ 73 in the following expanding pipe, horizontal well ball seat lower end is connected with guide shoe by the oil pipe of Φ 73, packer in the last expanding pipe, packer is a hollow body in constant pressure valve and the following expanding pipe.
Described Φ 73 oil pipes are band rigidity centralizer.
The utlity model has following beneficial effect: owing to take such scheme, the external casing packer feed pathway of the envelope that expanded places fully by cementing truck and suppresses in the upper and lower expanding pipe of interior pipe string tool that expands in the formed closed chamber of packer, energy is the control valve internal pressure accurately, and by the controlled pressure data, and the control operation process satisfies the requirement of expanding sealing sleeve external packer of pipe.This technology has stable performance, little, the high reliability features of risk, can fundamentally solve the bruising control inaccuracy of conventional method when the operation of expanding sealing sleeve external packer of pipe, can't test envelope and test problem such as scurry, effectively improve external casing packer and set success rate, and can satisfy the requirement of The field fully in time to setting effect evaluation.
The utility model is described in further detail below in conjunction with the embodiment accompanying drawing:
Description of drawings
Fig. 1 is a schematic diagram of the present utility model.
Among the figure: 1, go up packer in the expanding pipe; 2, constant pressure valve; 3, packer in the following expanding pipe; 4, horizontal well ball seat; 5, guide shoe; 6, pit shaft; 7, external casing packer; 8, bunch tube.
The specific embodiment
Interior pipe string tool comprises packer 3, horizontal well ball seat 4, guide shoe 5 and connector Φ 73 oil pipes in packer 1 in the expanding pipe, constant pressure valve 2, the following expanding pipe; Be connected with constant pressure valve 2 by Φ 73 oil pipes between the packer 3 in packer 1 and the following expanding pipe in the last expanding pipe, packer 3 is connected with horizontal well ball seat 4 by Φ 73 oil pipes in the following expanding pipe, horizontal well ball seat 4 lower ends are connected with guide shoe 5 by Φ 73 oil pipes, and the interior packer 3 of packer 1, constant pressure valve 2 and following expanding pipe is a hollow body in the last expanding pipe.
The pipe string tool is as follows to the construction technology process of the bloated envelope of external casing packer in utilizing:
1) external casing packer 7 is connected with bunch tube 8, bunch tube 8 is lowered in the pit shaft 6.
2) with interior pipe string tool according to guide shoe 5, Φ 73 oil pipes, horizontal well ball seat 4, Φ 73 oil pipes (band rigidity centralizer), down separator 3, Φ 73 oil pipes (band rigidity centralizer), constant pressure valve 2, Φ 73 oil pipes (band rigidity centralizer) in the expanding pipe, go up being linked in sequence of separator 1 in the expanding pipe, Φ 73 oil pipes (band rigidity centralizer), crossover sub, the back joins with rod string, be lowered in the bunch tube 8 that is connected to external casing packer 7, packer 3 splits two ends at external casing packer 7 in packer 1 and the following expanding pipe in last expanding pipe.
3) suppress by expand envelope medium such as clear water or mud with cementing truck from well head, when pressure is elevated to 2.0~3.0MPa, voltage stabilizing 1 minute, allow the interior packer 3 of interior packer 1 of expanding pipe and following expanding pipe expand and seal, the interior packer 1 of expanding pipe is sealed with internal surface of sleeve pipe with interior packer 3 positions of following expanding pipe contact.
4) continue to boost, when pressure was elevated to 4.0~5.0MPa, constant pressure valve 2 was opened in voltage stabilizing 1 minute.
5) continue to boost, when pressure is elevated to 9.0~11.0MPa, voltage stabilizing 10 minutes, external casing packer 7 sets, and makes external casing packer 7 and shaft in wall pressing.
6) unload push back zero after, packer 3 deblockings in packer 1 and the following expanding pipe in the last expanding pipe, the pipe string tool is downward in moving, and suppresses again by the bloated medium that seals.
7) return row's situation according to well head liquid, estimate and to set effect, just whether external casing packer 7 qualified with the shaft in wall pressing, has only external casing packer 7 and shaft in wall to form seal, external casing packer 7 just cry set qualified; If external casing packer sets successfully, then forward step 8) to; If it is unsuccessful that external casing packer 7 sets, repeating step 3), 4), 5), 6), 7) carry out operation again, set successfully up to external casing packer 7.
8) after finishing 7 operations of expanding sealing sleeve external packer of pipe, the pipe string tool boosts to about 18.0MPa to the appropriate location in continuing to transfer, and horizontal well ball seat 4 shear pins are cut off, and hydrophthalmia is opened, and pressure reduces to zero, and interior pipe string tool deblocking trips out drilling tool, and construction finishes.
Need to prove the activities that connects an external casing packer 7 on bunch tube 8 only has been described in the technological process, in fact the quantity of bunch tube 8 upper joint sleeve external packer of pipe 7 can be selected a plurality of as required.During elected majority, above-mentioned activities is operation one by one from top to bottom then, and the external casing packer 7 of connection all sets successfully on bunch tube 8.
Because packer and constant pressure valve belong to existing technology in external casing packer 7, the pipe, so do not do too much explanation in the manual.
