Ultra deep well precision instrument of oil and gas exploration
On November 23, 2013, the reporter understands from oil bohai drilling engineering company, the company 3-75-7 Wells in dagang oil drilling test of BH new type of electromagnetic wave resistivity instrument signal is normal, the resistivity and gamma measurement data are accurate, fill in the our country more than 6000 metres ultra deep Wells and complex geological structure well precision blank of oil and gas exploration, realize the upgrading of super deep well precision instrument of oil and gas exploration.
So far, the instrument has successively completed the field test of three well, well into the 206 hours over the instrument system is stable, accurate measurement data, and to achieve industrial application of water Ping. The successful development of the equipment is finished BH - LWD (logging while drilling) upgrading, break through the domestic electromagnetic wave resistivity instrument developed by technical bottlenecks, and successively in dagang oil region west 44-3-2 Wells, room 1-3-75-7 in 6 Wells and well tested, instrument system working properly all the way, the resistivity and gamma data real-time decoding accuracy, had the requirement of industrialized production.
It is understood that in recent years, with the increase of oil and gas exploration and development at home and abroad and the difficulty, 6000 meters above the ultra deep Wells and complex geological structure well rise year by year, the number of the first generation of BH - LWD cannot meet the new situation of oil and gas
The need of exploration and development, if depend on expensive imported products, will greatly increase the cost of production. Therefore, CNPC bohai drilling engineering company in October 2010, the cooperative development of LWD equipment of decision-making, and formed by two Chinese oil group corporate level technical experts for the project principal research and development team, cooperation with foreign technology experts research.
R&d team research mechanism of electromagnetic wave resistivity measurement, from two parts of machinery and software research, at the same time to complete the resistivity instrument mechanical structural design and manufacturing, has developed a comprehensive performance superior BH new type of electromagnetic wave resistivity instrument. The successful development of new type of electromagnetic wave resistivity instrument USES the symmetry antenna structure and double frequency electromagnetic measurement method, the tool structure, the measuring accuracy and stability than the first generation of instrument
Comprehensive performance.
According to the relevant person in charge of the company, the successful design of the electromagnetic wave resistivity instrument, makes the CNPC bohai drilling engineering company has the ability of manufacturing advanced LWD system, a new type of resistivity tool combined with near-bit measurement system under development, formed new BH - LWD instruments with international level.
