Abstract
The utility model relates to one and tests pipe device, belongs to petroleum exploration and development oil-water well workover treatment instrument technical field.Test pipe device to be made up of top connection, plug Pressure Block, urceolus, plug Pressure Block is fixed on top connection inner chamber bottom by shear pin, and the inner chamber of top connection and plug Pressure Block forms the conicylindrical passage of a rounding off, and top connection lower end is connected with urceolus by screw thread.The lower end of urceolus and lower contact screwed connection, the external diameter of plug Pressure Block is greater than the inner via hole of lower contact.Drop into plug from drilling tool inner chamber during construction and be pumped to plug Pressure Block, pressure testing is carried out to drilling tool, detect latus rectum and tubing string sealing in tubing string, continue after qualified to suppress to cut short shear pin, plug Pressure Block and plug fall interior pipe top, during trip-out, workover fluid is flowed in well by the inlet opening at screen casing top, prevents foreign material to block circulation canal.During trip-out, plug Pressure Block and plug take ground out of with drilling tool, avoid contaminated environment, realize safety in production, improve speed of application.
Description
Technical field
The utility model relates to one and tests pipe device, belongs to petroleum exploration and development oil-water well workover treatment technical field.
Background technology
In oil well repairing operation construction, as noted ash, well cementation etc., requiring to detect entering latus rectum and sealing in well drilling tool, meeting construction technical requirement.At present, oil field comprises ball seat and spheroid to the union of testing that well tests pipe conventional, and ball seat is connected on water injection string low side, when needing to test pipe to water injection string pressure testing, from the pitching of oil pipe inner chamber, suppress oil pipe pressure test, the sealing of inspection tubing string, after having tested, tubing string intracavity bottom is in sealing state, tubing string inner accumulated suppresses liquid, and when lift pipe string, the liquid of suppressing of tubing string inner accumulated easily sprays from well head, both contaminated environment, affects safety in production again.Patent No. ZL200720187772.6 discloses a kind of oil field water well sliding bush type pipe testing device, its body interior is provided with cone by slide core, install sealing ring between main body inner wall and slide core, be also provided with sealing ring between cone and slide core, slide core is fixed on main body inner wall by shear pin.If water injection string is missed, can verify whether oil pipe has leakage, when testing pipe, cone is dropped into downwards in oil pipe, just building the pressure from oil pipe and testing pipe, test pipe complete, continue to improve pressure and destroy slide core, release liquid in pipe, the method can be verified the sealing of tubing string and release tubing string inner accumulated and suppress liquid, but its slide core falls in well, easily cause down-hole accident, and there is the technological deficiency that cannot detect latus rectum in tubing string.
Summary of the invention
The purpose of this utility model cannot detect latus rectum in tubing string to overcome the existence of above-mentioned prior art, and the technological deficiency of trip-out contaminated environment, provides one to test pipe device.
The utility model is made up of top connection, plug Pressure Block, urceolus, plug Pressure Block is fixed on top connection inner chamber bottom by shear pin, the inner chamber of top connection and plug Pressure Block forms the conicylindrical passage of a rounding off, and top connection lower end is connected with urceolus by screw thread.The lower end of urceolus and lower contact screwed connection, the external diameter of plug Pressure Block is greater than the inner via hole of lower contact.
The beneficial effects of the utility model are: drop into plug from drilling tool inner chamber during construction and be pumped to plug Pressure Block, pressure testing is carried out to drilling tool, detect latus rectum and tubing string sealing in tubing string, continue after qualified to suppress to cut short shear pin, plug Pressure Block and plug fall interior pipe top, during trip-out, workover fluid flows in well by the inlet opening at screen casing top, because the effect precipitating chamber prevents foreign material to block circulation canal.During trip-out, plug Pressure Block and plug take ground out of with drilling tool, avoid contaminated environment, realize safety in production, improve speed of application.
Accompanying drawing explanation
Fig. 1 is the utility model section of structure.
Detailed description of the invention
The utility model is made up of top connection 1, plug Pressure Block 2, urceolus 5, plug Pressure Block 2 is fixed on top connection 1 inner chamber bottom by shear pin 4, the top of top connection 1 inner chamber and the inner chamber of plug Pressure Block 2 form the conicylindrical passage of a rounding off, top connection 1 lower end is connected with urceolus 5 by screw thread, the lower end of urceolus 5 and lower contact 7 screwed connection, the external diameter of plug Pressure Block 2 is greater than the inner via hole of lower contact 7, prevents plug Pressure Block 2 from falling in well.
Described urceolus 5 inner chamber bottom is provided with holes every sieve, prevents plug Pressure Block 2 from falling in well further.
Pipe 6 in described lower contact 7 upper end welding, interior pipe 6 end sealing, its outer tube wall has outage, meets liquid-circulating and drainage needs.
The internal diameter of described urceolus 5 is greater than the external diameter of interior pipe 6, forms precipitation chamber, realizes the collection to foreign material in tubing string, prevents foreign material from blocking the inner via hole of lower contact 7, is convenient to clear up the foreign material in precipitation chamber.
The outer wall of plug Pressure Block 2 has seal groove, sealing ring 3 is installed, realizes the sealing of plug Pressure Block 2 outer wall and top connection 1 inwall.
When testing pipe to drilling tool, the utility model is connected with running string, when testing pipe, plug is dropped in running string, circulation workover fluid promotes plug and enters top connection 1 and plug Pressure Block 2 conical internal cavity by running string inner chamber, sealing top tubing string inner chamber, on request to pipe string pressure test, realize detecting latus rectum and tubing string sealing object in tubing string, continue after qualified to suppress and cut off shear pin 4, plug Pressure Block 2 and plug drop on the top of interior pipe 6, workover fluid enters sleeve pipe through the outage of interior pipe 6 and lower contact 7 inner via hole, release and suppress liquid in tubing string, the foreign material that simultaneously workover fluid carries are deposited in the precipitation chamber that urceolus 5 and interior pipe 6 formed, foreign material are prevented to block circulation canal.During trip-out, plug Pressure Block 2 and plug take ground out of with drilling tool, owing to not having liquid accumulation in tubing string, avoid contaminated environment, realize safety in production, improve speed of application.
