Description
Technical field
The present invention relates to oil and gas development and Exploration Domain, particularly relate to transmission While-drilling down-hole measurement data to the data transmission system on ground and method.
Background technology
Along with the quick growth of offshore drilling and the development of horizontal well technology, the application of logging while drilling technology is also more and more extensive.Be with the main distinction of Regular wireline: the real-time of the data acquisition of well logging during.That is, formation data obtains, thus closer to undisturbed formation when drilling fluid has slight invasion or do not invade.Due to, while drilling well, complete the test of formation data and be transferred to ground and carry out field assay and explanation, not only save drilling period, and drilling well can be instructed, regulate wellbore trace and improve drilling course, therefore, how the signal in shaft bottom is transferred to the key link that ground is logging while drilling technology, is also one of restriction logging while drilling technology development " bottleneck " simultaneously.
At present, for by the method for shaft bottom Signal transmissions to ground, real-time Transmission mode and memory-type transmission means is divided into.Real-time Transmission mode is, by various wired or wireless data transfer mode, the data of measurement while drilling are transferred to ground in time.This mode is to instructing drilling well, and the geosteering particularly during drilling well has very important meaning, but current various data transmission is all difficult to meet requirement down-hole mass data being transferred to timely and effectively ground.Memory-type transmission means refers to that the data of well logging during are directly stored in inside survey tool, and when pulling out of hole, when mentioning ground with brill instrument, then by cable digital independent out, this mode can complete the collection of mass data, but real-time is inadequate.
In wire transmission mode, comprise cable transmission mode, Optical Fiber Transmission mode and drill pipe transmission mode.The document 1 (" research of Intelligent Drill String information and electrical power transmission system, oil drilling technology " 2006,34 (5): 10-13.) following content is disclosed: cable is that subordinate enters armored cable in drilling rod with the method for brill Signal transmissions, and then signal transmission.But along with the intensification of drilling depth, by cable with brill instrument emersion ground, or in advance cable must be interted in drill pipe bore during adjunction unit cable.Document 2 (" with brill data New Technologies of Transmission ". oil instrument; 2004; 18 (6): 26-31.) following content is disclosed: Optical Fiber Transmission mode is lowered in well by the optical fiber with topping; optical fiber is connected to ground from bottom with brill instrument, and then carries out the transmission with boring data by optical fiber.Because the effect of optical fiber is the same with cable, the problem produced also is identical.Document 3 (" rotary steerable drilling state-of-the-art and prospect ". petroleum machinery, 2006,34 (4): 66-70) following content is disclosed: drill pipe transmission mode is arranged in drilling rod by conductor to become drilling rod part of the whole, the special link block being assemblied in tool joint makes whole drill string form electrical signal paths, and then realizes data transmission.
These modes are owing to adopting wired connection above, it is advantageous that transmission speed quickly, far above wireless mode.But cable, optical fiber, drill rod special connector all need to be arranged on whole pit shaft, when drilling well, because drilling rod causes these cable medium very easily to damage in the high-speed rotary change of team.Therefore the shortcoming that the many existence of these prior aries are common is: poor reliability, manufacture craft relative complex, and often affects normal drilling process.Thus these prior aries above are applied less in actual well logging during manufacturing process.
