Detailed Description
The invention is further described below with reference to the accompanying drawings:

In this embodiment, the number of coarse upper branch pipes 2 is one, the number of fine upper branch pipes 3 is one, the number of lower branch pipes 6 is one, a large-flow upper layer collector is formed, a small-flow upper layer collector is formed, the number of lower layer collectors is one, the flow distribution of the large-flow upper layer collectors is 60% of the total flow, the distribution flow of the small-flow upper layer collectors is 20%, and the distribution flow of the lower layer collectors is 20%. This is a two-layer three-channel structure.
The flow of the thick upper branch pipe 2 accounts for 60%, the structural strength of the material corresponding to the high-flow upper collector is designed to be low in compression resistance, namely, the collector branch pipe is deformed and blocked when the collector branch pipe is subjected to small extrusion force, and the fluid passing capacity of the thick upper branch pipe 2 is reduced to zero from the maximum (60% of the total flow). When the collector is extruded and deformed, the collector is equivalent to a flow regulating and reducing switch.
The extrusion deformation condition of the high-flow upper collector can be deduced through the change of the flow in the fine flow guide pipe 19 on the ground, and then the extrusion force on the sleeve 16 during the swelling displacement of the stratum can be deduced according to the stress-strain relation set before the product leaves the factory.
The flow rate of the fine upper layer branch pipe 3 accounts for 20 percent, and the structural strength of the material corresponding to the small flow rate upper layer collector is designed to be high in compression resistance. Only when the branch collector is further extruded with high strength, the branch collector is deformed to start to block the thin upper branch pipe 3, the deformation is more serious along with the increase of extrusion force, and the flow of the flow branch pipe is also changed from large to small. By comparing the calibration curve of the pressure-strain (deformation) - (deformation) flow of the collector before delivery, a larger extrusion force of the stratum on the casing 16 can be estimated from the flow change in the high extrusion force stage.
The flow distribution ratio of the lower-layer branch pipe 6 is 20%, the water inlet holes are downward, the lower-layer collector is positioned below the bottom end of the mudstone layer, and the mud stone layer cannot be extruded to the flow branch pipe when swelling. After the two branch collectors at the upper layer are closed by extrusion deformation, the lower layer collector can still conduct and transmit the hydraulic parameters of annular fluid.
