In oil field development, the situation of many formation production of a bite oil well and operation is very general, and two stratum are for example arranged, the upper strata production of need recovering the oil, and lower floor needs water filling.At present, conventional flow string can only provide a fluid passage, can't satisfy two stratum and carry out different operating types simultaneously, like this can only be by boring two mouthfuls of wells, just can carry out different operations to different stratum, make production efficiency lower, development cost is higher.Especially the exploitation of offshore oilfield is limited by offshore boring island, the well head limited amount, and the influence to development efficiency that causes thus is just particularly serious.
Summary of the invention
The utility model provides a kind of bridge-type binary channels production adapter system that can utilize same pit shaft two stratum to be taked the different work mode for solving the technical problem that exists in the known technology.
The technical scheme that the utility model is taked for the technical problem that exists in the solution known technology is:
A kind of bridge-type binary channels is produced adapter system, it is characterized in that: comprise bridge-type binary channels joint and location seal modules, described bridge-type binary channels joint is provided with overlying strata-oil pipe interface channel and sub-surface-oil jacket annular space interface channel, be connected with top connection at bridge-type binary channels upper end of joint by screw buckle, bridge-type binary channels joint lower end is connected with the location seal modules by screw buckle, seal modules lower end, location is connected with box cupling by screw buckle, the box cupling lower end is connected with ported sub by screw buckle, the ported sub lower end is connected with guide sub by screw buckle, and bridge-type binary channels joint is provided with the centre bore that links to each other with oil pipe.
The utility model can also adopt following technical scheme:
Described sub-surface-oil jacket annular space interface channel is that the radial section that is communicated with central tube is oblong radially groove.
Described overlying strata-oil pipe interface channel is that the sub-surface-connection top connection of oil jacket annular space interface channel both sides and the axial cross section of oil jacket annular space are the axially extending bore of circular arc.
It is the single piece structure that described bridge-type binary channels is produced joint.
Described screw buckle connects employing API standard button-type.
Have several holes on the described ported sub perpendicular to its center line.
Advantage and the good effect that the utlity model has are: the utility model has adopted technique scheme, different stratum is being carried out under the different operation situations, this bridge-type binary channels is produced joint by being connected with other seal modules of oil pipe and lower end, make in the pit shaft that the stratum isolates mutually up and down, oil pipe is communicated with overlying strata-central tube interface channel, the lower floor stratum is by the sub-surface-oil jacket annular space interface channel on the passageway bridge joint body, realized providing the purpose of different fluid passage for two stratum, and be independent of each other, can carry out different operating types; The ported sub that connects in the system having carried out particular design aspect the increase fluid flow area, has reduced the flow losses in the operation, and guide sub then is lowered at tubing string and plays guide effect in the process, and tubing string is lowered to smoothly.The utility model is not only simple in structure, be convenient to operation and low cost of manufacture.

The specific embodiment
For further understanding summary of the invention of the present utility model, characteristics and effect, exemplify following examples now, and conjunction with figs. is described in detail as follows:
See also Fig. 1-Fig. 2, a kind of bridge-type binary channels is produced adapter system, comprises bridge-type binary channels joint 2 and location seal modules 3, and it is the single piece structure that the bridge-type binary channels is produced joint.Described bridge-type binary channels joint 2 upper ends are connected with top connection 1 by screw buckle, bridge-type binary channels joint 2 lower ends are connected with location seal modules 3 by screw buckle, seal modules 3 lower ends, location are connected with box cupling 5 by screw buckle, box cupling 5 lower ends are connected with ported sub 6 by screw buckle, have several holes on the ported sub 6 perpendicular to its center line, ported sub 6 lower ends are connected with guide sub 7 by screw buckle, be provided with overlying strata-oil pipe interface channel 2-2 and sub-surface-oil jacket annular space interface channel 2-1 on bridge-type binary channels joint 2, bridge-type binary channels joint 2 is provided with the centre bore that links to each other with oil pipe.Sub-surface-oil jacket annular space interface channel 2-1 is that the radial section that is communicated with central tube 4 is oblong radially groove.Overlying strata-oil pipe interface channel 2-2 is that the connection top connection 1 of sub-surface-oil jacket annular space interface channel 2-1 both sides and the axial cross section of oil jacket annular space are the axially extending bore of circular arc.Screw buckle connects employing API standard button-type.
Operating principle of the present utility model is:
In the use, be the annular space of instrument and sleeve pipe from then on to the underground water that injects, the sub-surface-oil jacket annular space interface channel 2-1 by bridge-type binary channels joint 2 injects, and through central tube, is injected in the lower floor stratum; The oil of being exploited is the hole by ported sub 6, and is up through the annular space that central tube and ported sub 6 forms, and 2-2 is up for the overlying strata-central tube interface channel by bridge-type binary channels joint 2 then, passes through top connection and exploits ground.Screwed connection has oil pipe 8 in the top connection 1, and oil pipe is communicated with overlying strata-oil pipe interface channel 2-2, makes overlying strata directly be communicated with ground by oil pipe; Bridge-type binary channels joint 2 Center-to-Center pipes 4 connect, by its another seal modules and lower floor's combination of zones that connects down, make the lower floor stratum by the sub-surface-oil jacket annular space interface channel 2-1 on passageway bridge joint 2 bodies, be communicated with the oil pipe-casing annulus more than the top packer, and be connected with ground by the oil jacket annular space; Because two passages are independent mutually, make the two-way fluid be independent of each other, thereby realized carrying out in the same well pattern of bidirectional fluid operation, not only provide cost savings, and improved operating efficiency greatly.
