Abstract: The present invention belongs to the field of environment monitoring, particularly relates to a CO2 storage state networking monitoring device, system and method with multi-information fusion. The present invention comprises: obtaining orientation electrical signal data and real-time pressure signals, analyzing a fluid flowing state at a view of a pressure sensor through the real-time pressure signals, and obtaining a CO2 flowing state through the orientation electrical signal data; and obtaining a CO2 regional storage state by combining an orientation CO2 content, a CO2 flowing state and the fluid flowing condition at the view of the pressure sensor. By combining accurate short-range CO2 boundary monitoring of orientation electrodes with long-range monitoring of pressure sensors to achieve a wide range of CO2 flowing state monitoring, the present invention can observe more data with higher reliability and effectively aims at the problem of strong inter-well heterogeneity.

The stator includes: a housing, where the housing has an accommodation space, and an oil inlet is disposed on the housing; a ring-shaped iron core punching sheet, where the iron core punching sheet is disposed in the accommodation space, and abuts against an inner wall of the housing; a spacer sleeve, where the spacer sleeve is sleeved in the iron core punching sheet, an outer surface of the spacer sleeve abuts against a side that is of the tooth part and that faces away from the yoke part, and a slot opening of the stator slot fits with the spacer sleeve to form a third cooling channel; and a flow guiding assembly, where the flow guiding assembly is disposed in the accommodation space. The three-layer oil-injection cooling design can improve a heat dissipation capability of the stator.

Abstract: The present disclosure belongs to the field of geological exploration, and particularly relates to a seismic acquisition system based on a frequency domain expansion MEMS sensor, aiming at solving the problem that vibration frequencies exceed the frequency range of the MEMS sensor due to strong vibrations and cross coupling of multi-frequency signals usually occurring in well logging while drilling. When the MEMS sensor suffers strong vibrations or the MEMS sensor that can be selected cannot ensure that the frequency requirement of a measurement signal is stably met, the frequency domain expander of the present disclosure expands the frequency domain of a detection signal, so that the MEMS sensor can measure strong vibrations and out-of-band frequencies to a certain extent, the application range of the seismic acquisition system is extended, and the anti-mutation capability of the seismic acquisition system is improved.

Abstract: The present invention provides a cartridge, a detection method, and a detection device capable of stabilizing the liquid level of a sample accommodated in a chamber in a predetermined state. A cartridge 20, that is rotated around a rotating shaft 42 for detecting a target substance, is provided with a chamber 100 in which a sample containing a target substance is stored. The chamber 100 includes a first region 110 in which a sample is stored, a second region 120 disposed at a position closer to the rotating shaft 42 than the first region 110, and a protrusion 130 protruding from a position between the first region 110 and the second region 120 to the inner side of the chamber 100.
