The invention discloses an automatically-controlled constant-pressure strip making method. According to the method, a sealed nozzle package is used for containing alloy liquid, and the alloy liquid issprayed onto the surface of a cooling roller which is rapidly rotating through a nozzle under the nozzle package, and a solid alloy strip is formed; inert gas is introduced into the nozzle package inthe strip spraying process, the pressure of the inert gas is used for compensating the hydraulic pressure drop caused by the liquid level drop of the alloy liquid during strip making, the compensation air pressure value is automatically calculated and controlled in real time by a center console according to a compensation gas pressure change equation according to the strip spraying process parameters, and the pressure of the alloy liquid sprayed from the nozzle is kept constant in the entire strip making process. The center console also realizes the real-time and automatic control over the process parameters, such as the alloy fluid temperature and the rotating speed of the cooling roller, in the entire strip making process, the actual thickness of the strip is fed back in real time according to an on-line thickness measuring instrument, the inner compensation pressure of the nozzle and the rotating speed of the cooling roller are adjusted automatically according to the actual thickness of the strip, and the stable strip thickness is achieved.

The invention provides a deep well hydrocarbon reservoir temperature and pressure intelligent on-line monitoring device. A test plane and a transition plane are processed in the eccentric oil pipe, an optical fiber Bragg grating strain sensor is formed on the test plane through high-temperature bonding, one end of the optical fiber Bragg grating strain sensor is fixedly arranged on the test plane, and the other end of the optical fiber Bragg grating strain sensor passes through an optical fiber channel arranged between the test plane and the transition plane to reach the transition plane. One end, near the transition plane, of the optical fiber channel is connected with a stainless steel capillary pipe, the optical fiber penetrates into the stainless steel capillary pipe after being led out from the optical fiber channel, the stainless steel capillary pipe approaches to the transition plane and extends to a position near an optical fiber modem interface on the well, and the optical fiber is protected from being influenced by external severe environment in the whole process. The on-line monitoring device related by the invention realizes the deep well oil pipe structure integration, and has the advantages that the size is small, no additional auxiliary structure is adopted, the anti-interference capability is high, signals are stable and reliable, the response speed is high, and the like, and the on-line obtaining precision and the reliability of key information such as deep well hydrocarbon reservoir temperature and pressure can be obviously improved.
