Problems solved by technology
In this way, the downhole front-end sensor basically has no function of processing information. All data needs to be sent to the processing node on the bus before further calculation, analysis and judgment can be performed. This not only reduces the network communication rate, but also causes the bus waste of transmission efficiency

Embodiment Construction
[0032] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings.
[0033] The network communication structure based on the C / S (Client / Server) structural mode (that is, the client / server mode) used in this embodiment can make full use of the advantages of the hardware environment at both ends, and then reasonably allocate tasks to the client and server-side implementation. The client in this mode is not an input and output sensor or acquisition device without computing power, but a communication unit with certain data processing and storage capabilities, which can communicate with the downhole information server at high speed under the control of the CPU; and the downhole information The server has a common interface, which can easily access multiple downhole equipment of different manufacturers, and complete the transmission con...

The invention discloses a downhole and surface data transmission system and method, and relates to the technical field of petroleum drilling. The system includes: ground server, downhole information server, and downhole client. The method includes: a data transmission method between the downhole information server and the ground server, and a data transmission method between the downhole information server and the downhole client. The data transmission system and method based on the C / S mode of the downhole information server and the surface server provided by the present invention can not only realize the common link layer and the physical layer communication, but also further realize the data communication control between the transmission layer and the network layer. In the case of conventional drilling, it can solve the problem of multipoint-to-multipoint data transmission between multiple downhole clients, downhole information server and ground server, and overcome the low transmission rate, simple control method and high bit error rate of traditional bus methods. Insufficient, improve the data transmission rate and real-time performance of the whole system.
Description
technical field [0001] The invention relates to the technical field of petroleum drilling, in particular to a data transmission system and method between downhole and surface. Background technique [0002] With the development of logging while drilling and steering technology, logging while drilling methods are constantly enriched, such as acoustic logging, azimuth density neutron logging, real-time resistivity images, imaging logging at multiple detection depths, near-bit geosteering logging, etc. wells, rotary steerable logging, etc. If the diversified LWD and steering technologies can be combined and used at the same time, it will provide rich downhole information for drilling staff to make real-time decisions, control the most favorable well trajectory, and achieve the expected drilling purpose. However, it is not easy to use multiple downhole measurement tools at the same time. Multiple measurement and control equipment will greatly increase the difficulty of informati...
