Description
Technical field
The present invention relates to oil and gas development and Exploration Domain, especially relate to a kind of release type with data uploading method under drilling well and system.
Background technology
Along with the rapid growth of offshore drilling and the development of horizontal well technology, the application of logging while drilling technology is also more and more extensive.The main distinction of well logging during and normal cable well logging is the real-time of its data acquisition, and formation data is to obtain in the situation that drilling fluid has slight invasion or do not invade, thereby more approaches undisturbed formation.In drilling well, complete the test of formation data and be transferred to ground and carry out field assay and explanation, not only saved drilling period, and can instruct drilling well, regulate wellbore trace, improve drilling well process.Therefore, how the signal in shaft bottom is transferred to the key link that ground is logging while drilling technology, is also one of the development of restriction logging while drilling technology " bottleneck " simultaneously.
Whether well logging during is at present divided into real-time Transmission mode and memory-type transmission means according to transfer of data.Real-time Transmission mode is, by various wired or wireless data transfer modes, the data of measurement while drilling are transferred to ground in time.This mode is to instructing drilling well, and particularly geosteering when drilling well has very important meaning, but current various transfer of data are all difficult to reach the requirement that down-hole mass data is transferred to timely and effectively to ground.Memory-type transmission means refers to that the data of well logging during are directly stored in survey tool the inside, in the time pulling out of hole, when mentioning ground with brill instrument, then by cable, data is read out, and this mode can complete the collection of mass data, but real-time is inadequate.
Wire transmission mode comprises cable transmission mode, optical fibre transmission mode and drill pipe transmission mode.Paper 1 (" research of Intelligent Drill String information and electrical power transmission system, oil drilling technology " 2006,34 (5): 10-13.): cable is to be lowered to armored cable in drilling rod inside, signal transmission with the method for boring signal transmission.Along with the intensification of drilling depth, add and while making up a joint, must propose cable and with boring instrument, or in advance cable is interted in drill pipe bore.Paper 2 (" with boring transfer of data new technology ". oil instrument, 2004,18 (6): 26-31.): optical fibre transmission mode is that the optical fiber with topping is lowered in well, is connected to ground from bottom with boring instrument.The effect of optical fiber is the same with cable.Paper 3 (" rotary steerable drilling state-of-the-art and prospect ". petroleum machinery, 2006,34 (4): 66-70): drill pipe transmission mode is that conductor is arranged on and in drilling rod, becomes drilling rod part of the whole.The special link block that is contained in tool joint makes whole drill string form electrical signal paths, realizes transfer of data.These modes, owing to adopting wired connection, it is advantageous that transmission speed is very fast, far above wireless mode above.But cable, optical fiber, drill rod special connector all need to be arranged on whole pit shaft, and when drilling well, drilling rod is at High Rotation Speed, and above these all very easily damage.Therefore more there is common shortcoming poor reliability, manufacture craft relative complex in these prior aries, and often affect normal drilling process.These prior aries are applied less in actual well logging during manufacturing process above.
