Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail:
As shown in Figure 1, this water injection well can be tested envelope measurement and adjustment instrument and comprise main body 1, flow transmitter 3, overcoat 4, lower pressure sensor 5, upper pressure sensor 6, lower main body 7, upper sealing ring 8, mandrel 10, driving sleeve 12, lower sealing ring 13 and straight line freewheel clutch assembly 15, wherein, described upper main body 1 is threaded with flow transmitter 3, and flow transmitter 3 is welded and fixed with lower main body 7 and is connected; Described lower main body 7 top wall is equipped with pressure sensor 1 and pressure sensor 26, be set with upper sealing ring 8 and lower sealing ring 13 under lower main body 7 outer wall is positioned at pressure sensor successively and be fixed on the outer wall of lower main body 7 by pin respectively, above-mentioned flow transmitter 3, pressure sensor 1, pressure sensor 26, upper sealing ring 8 and lower sealing ring 13 outer suit overcoat 4; Lower main body 7 endoporus Lower Half is equipped with mandrel 10, and the lower end of mandrel 10 is connected with straight line freewheel clutch 15; Mandrel 10 outer suit driving sleeve 12, mandrel 10 is connected with driving sleeve 12 by straight line freewheel clutch assembly 15, and radial upper attachment pegs 11 and lower link pin 14 are housed between driving sleeve 12, lower main body 7 and mandrel 10.
With water inlet 2 in described upper main body 1, with delivery port 9 in lower main body 7, with the pod apertures 16 communicated with flow transmitter 1 on the sidewall of lower main body 7.
Described upper sealing ring 8 upper end is fixed on lower main body 7 near flow transmitter 3 place by pin, and lower end is connected with driving sleeve 12 by above-mentioned upper attachment pegs 11; Lower sealing ring 13 upper end is fixed on delivery port 9 lower end of lower main body 7 by pin, and lower end is connected with driving sleeve 12 by lower link pin 14.
Mandrel 10 promotes driving sleeve 12 by straight line freewheel clutch assembly 15, driving sleeve 12 drive upper sealing ring 10 and lower sealing ring 13 simultaneously distending by bridge type water distributor distributing hole both sides sealing, current enter flow transmitter 1 by water inlet 2 through pod apertures 16, flow into water filling layer by delivery port 9, now water injection well can test envelope measurement and adjustment instrument can measure in real time the water filling water yield.
When upper sealing ring 8 and lower sealing ring 13 simultaneously distending by bridge type water distributor distributing hole both sides sealing after, mandrel 10 continues to move up, straight line freewheel clutch assembly 15 makes mandrel 10 and driving sleeve 12 depart from, after mandrel 10 is by the delivery port 9 upper end sealing in lower main body 7, segmented state is between stratum and oil pipe, tubing pressure got by upper pressure sensor 26, lower pressure sensor 1 gets pressure between upper sealing ring 8 and lower sealing ring 13, i.e. strata pressure, now water injection well can test envelope measurement and adjustment instrument can carry out testing envelope by segmented state between formation and oil pipe.
When carrying out the operation of survey tune, by working truck and rig tool, water injection well can be tested envelope measurement and adjustment instrument loads in water injection well, the regulating arm that water injection well can test envelope measurement and adjustment instrument is stretched out, measurement and adjustment instrument docks with bridge type water distributor, distending is by bridge type water distributor distributing hole both sides sealing simultaneously for upper sealing ring 8 and lower sealing ring 13, and now water injection well can be tested envelope measurement and adjustment instrument and can measure in real time the water filling water yield.When carrying out testing envelope operation, the while of upper sealing ring 8 and lower sealing ring 13, distending is by bridge type water distributor distributing hole both sides sealing, lower main body 7 delivery port 9 upper end seals by mandrel 10, and now water injection well can be tested envelope measurement and adjustment instrument and can test envelope to segmented state between water filling layer and oil pipe.This water injection well can test envelope measurement and adjustment instrument owing to taking such scheme, under working condition of once going into the well, can carry out flow measuring and adjusting and test envelope two functions to water injection well.
