Embodiment 5: the invention relates to a data stability solution of a wireless data transmission real-time monitor, which comprises the following steps:
1. 2G/3G/4G multi-network self-adaptation to ensure data connection
In a signal transceiving remote terminal control unit (DAP) used by a wireless data transmission real-time monitor on the site of an oil-water well, a communication module supporting five-mode twelve-frequency is used, the communication speed of the module is high on the occasion of 3G or 4G, the connection is stable, and the module can be stably connected to a server in a 2G mode in the field without 3G or 4G signals.
2. Totally-enclosed technology of instrument main body
The wireless data transmission real-time monitor is in underground work throughout the year, particularly in an environment with extremely high corrosivity in a compact oil well, and a long-term sealing effect cannot be guaranteed in a common sealing mode, so that a fixed sealing process is adopted. That is to say, any sealing surface of the circuit cavity of the instrument and the outside is fixedly connected together by adopting a fully closed technology, and the leakage possibility is avoided.
3. Totally-enclosed underground corrosion-resistant pressure-bearing cable joint
During the construction of the well, the instrument and the cable need to be connected on site at a well site, and long-term corrosion resistance and complete sealing under the well are required to be guaranteed.
Petroleum contains gases such as water, hydrogen sulfide, light hydrocarbons and the like, and is extremely corrosive particularly in high-temperature and high-pressure environments. The test instrument must be electrically conductively connected to the cable core and be insulated and sealed. The fully-sealed cable joint is used for meeting the requirements, can bear high temperature and high pressure for a long time, ensures the power supply and communication of an instrument, and simultaneously prevents corrosion and avoids the instrument from falling off.
4. Well head anticorrosion bearing sealing mechanism
After the lower end of the cable is connected with an instrument and the weighting rod is hung underground, the weight of the instrument, the weighting rod and the cable can reach hundreds of kilograms, sealing is needed, locking strength needs to be absolutely guaranteed, and the cable cannot be damaged. All of the devices are convenient to put in, sealed and fixed for a long time and firm, and the devices are convenient to take out on the basis of the on-site construction conditions. Therefore, the anti-corrosion bearing sealing locking mechanism which is used at the wellhead for a long time is designed aiming at the project, and has the characteristics of convenience in site construction and tightness.
5. Multi-server mode for ensuring system stability
A database system of the permanent online downhole pressure monitoring system can simultaneously receive data transmission of a plurality of receiving servers. That is, in order to ensure the reliability of data communication, a plurality of data receiving servers can be operated at different places at the same time, and the data access point of each oil-water well site can be connected with at least 2 data receiving servers, so that even if one receiving server is powered off or fails, the other receiving servers can still operate as long as the other receiving servers do not have any influence on data.
6. Double pressure probe, signal reliability assurance
A pressure gauge in a permanent online underground pressure monitoring system is arranged underground for a long time to work, and in order to ensure the long-term reliability of the pressure gauge, a schematic diagram of a double-path pressure system adopted by an underground instrument is shown in figure 3.
If two pressure sensors are installed, one path can be used for collecting the pressure of the casing pipe, and the other path can be used for collecting the pressure of the oil pipe. Even if only when installing a pressure sensor, can inspect the repeatability of two way signal acquisition passageways, inspect the operating condition of singlechip, when a passageway breaks down, can use the data of another signal passageway.
Embodiment 6: the application range of the wireless data transmission real-time monitor is as follows:
1. pressure recovery testing and fluid level monitoring for production wells
2. Monitoring of downhole data of key oil-water well
