Description
Technical field
The present invention relates to be used for the long-range satellite communication of logging system.More specifically, the remote service monitoring that the present invention relates to utilize marine satellite to realize logging system, remote fault diagnosis maintenance, remote system control, remote real-time data transmission etc.
Background technology
Geophysical log or oil well logging also are in well logging, are called for short well logging, are geophysics characteristics such as the electrochemical properties that utilizes the rock stratum, conductive characteristic, acoustic characteristic, radioactivity, and the method for measurement geophysical parameters belongs to one of applied geophysics method.During oil drilling, after getting into the deep degree of planned well, all must log well, claim completion logging again, to obtain various petroleum geologies and engineering data, i.e. information such as reservoir depth, thickness is as completion and the firsthand information that develops oil fields.
Logging system mainly is divided into ground system and two parts of downhole instrument; Connect through 7 core armoured cables between this two; Ground system and cable all are installed on the logging truck, and during well logging, downhole instrument transferred or lift by the ground winch through cable; And supply power to downhole instrument through cable, realize the data communication of ground and down-hole simultaneously.
Because logging operation generally all is that natural environment is abominable in remote districts, communication condition is relatively poor; With regard to single oil well; The all devices in its well site, houses etc. are all built temporarily, do not have the wire communication network at all; Particularly at sea, meagrely-populated area such as desert, grassland, mountain area, even mobile phone does not all have signal; Also has some external area because the restriction of cost or security situation during logging operation, is generally only undertaken by local employee; Demands such as the remote service monitoring of logging system, remote fault diagnosis maintenance, remote system control, remote real-time data transmission can't realize at all.
On the other hand; At the mid-1970s; In order to strengthen the safety guarantee of marine vessel, International Telecommunications Union's decision is distributed to the maritime satellite communication service with 1535～1542.5MHz in the L-band and 1636.3～1644MHz, and the partial content among the Marisat just offers ocean ship use like this.Nineteen eighty-two has formed the Inmarsat system with International Maritime Satellite Organization (Inmarsat) management, begins to provide the global maritime satellite communication service.
Inmarsat utilizes synchronous satellite to navigation, aviation and offshore industry in danger and secure communication service and phone, fax, data and fax to be provided.Its wide coverage receives the terrestrial wireless electrical interference little, and inbound pacing is fast; Automaticity is high, and good communication quality utilizes maritime satellite system can solve the communication issue of naval searching mechanism effectively; No matter see all have unrivaled superiority from reliability, economy and practicality.Inmarsat is its existing communication satellite of retrofit just ceaselessly, so that more, better service are provided for the user.Along with the professional development of Inmarsat, it has become unique in the world international organization that communication service is provided for the sea, land and sky user at present.
The Inmarsat satellite mobile communication system has developed into the 4th generation (InmarsatIV).Except that traditional speech and data service; This system can be the mobile subscriber broadband data, services such as mobile high definition clear net cast, the image compatible with 3G transmits, big file speed biography is provided; And the BGAN service (BGAN) of adopting IP and circuit switched service, transmission rate reaches 492kbps.
Generally speaking, the Inmarsat system is made up of ship station, bank station, network coordinating station and satellite.Wherein satellite distribution in the Atlantic Ocean, 3 overhead satellites of the Indian Ocean and the Pacific Ocean have covered the almost whole earth, and make any point of three big oceans-the Pacific Ocean, the Atlantic Ocean and the Indian Ocean can both insert satellite, the work elevation angle of bank station is more than 5 °; Bank station (CES) is meant and is located near the earth station of seashore, returns various countries authorities to own, and returns their to manage.It is the interface of satellite system and ground system, is again control and access center; Network coordinating station (NCS) is a part of whole system.A network coordinating station is established in each marine site, and it also is two-band work; (SES) is provided in a side of the earth station on the ship at the ship station.The Inmarsat system is defined in and adopts the L frequency range between ship station and the satellite; Bank station and satellite adopt dual frequency range; Digital channel adopts the L frequency range, and the FM channel adopts the C frequency range, therefore for the C frequency range; The L frequency band signals of ship station to satellite must up-convert to the C frequency band signals at satellite and be forwarded to bank station again, and vice versa.
Just according to above about logging system and the described background technology of maritime satellite communications; Made the present invention; Wherein realized when the logging operation demand such as remote service monitoring, remote fault diagnosis maintenance, remote system control, remote real-time data transmission, satisfied the round-the-clock telecommunication needs in the logging operation logging system through the BGAN service (BGAN) that utilizes the Inmarsat marine satellite to provide.
