I. Related to Seismic Exploration Technologies Compressed - sensing Seismic Exploration Technology This technology breaks through the limitations of the traditional Nyquist sampling theorem and reduces production costs while meeting the sampling requirements of seismic signals. Although high - density seismic data acquisition can meet the requirements, its cost is too high, and compressed - sensing technology provides an important method for cost - reduction and efficiency - improvement in seismic acquisition. The rapid development of on - land and offshore simultaneous - source hybrid acquisition has laid the foundation for it. Related companies such as BP, Schlumberger, and BGP (Bureau of Geophysical Prospecting Inc., CNPC) have made significant technological progress. ConocoPhillips' Compressed Seismic Imaging (CSI) technology, which includes Non - Uniform Optimized Sampling (NUOS) technology, blended - source acquisition technology, data reconstruction technology, etc., has been commercially applied, greatly improving the acquisition efficiency and shortening the construction period. For example, it has achieved remarkable results in the on - land vibroseis seismic exploration project in Alaska. Artificial Intelligence Seismic Interpretation Technology Traditional seismic interpretation methods are difficult to handle massive data. Foreign companies such as Geophysical Insights use machine - learning and big - data - analysis technologies for seismic - attribute analysis, reducing the uncertainty of interpretation and promoting the development of quantitative interpretation. Paradigm's lithofacies - prediction technology based on machine - learning has a fast running speed, requires less manpower, and can provide more stable reservoir - description results. Seismic interpretation based on artificial - intelligence technologies such as deep - learning can make full use of massive data, shorten model - processing time, improve the real - time calculation of seismic - trace attributes and the visual analysis of basins in complex areas, thereby obtaining underground information more accurately and increasing the success rate of drilling. Elastic - wave Imaging Technology As an important branch of seismic exploration technology based on elastic - wave theory, its key R & D technologies, such as vector - signal processing, vector - noise suppression, and combined P - and S - wave initial - velocity modeling, are used to improve the full - waveform inversion and imaging effects and provide more detailed data for reservoir prediction. At present, this technology is still in the theoretical - research stage, and in the future, it will be deeply combined with high - performance - computing technology to improve efficiency and accuracy.

The detection distances of relevant prototypes launched by Schlumberger, Halliburton and other companies are constantly increasing. While - Drilling Long - Distance Detection technology can detect fluids and reservoir boundaries within tens of meters around the wellbore. When combined with various logging technologies, it can generate mapping maps that truly reflect the reservoir structure and fluids, which is conducive to optimizing well locations and oilfield - development plans.
III. Related to Logging Technologies Optical - fiber Logging Technology Optical - fiber logging technology is widely used for reservoir - parameter measurement in harsh downhole environments due to its characteristics such as anti - electromagnetic interference. Technologies such as distributed temperature, stress, and acoustic sensors are in their respective development stages. In the future, continuous measurement along the wellbore will be achieved, providing comprehensive downhole production data, detecting various downhole abnormal situations, and promoting the development of intelligent completions and digital oilfields. "One - Trip Logging" Logging Technology Taking logging while drilling instead of open - hole well logging as the development direction, although certain progress has been made, there are still bottleneck technologies to be solved. In the future, the realization of "one - trip logging" and synchronization with "one - trip drilling" will simplify the operation process, reduce costs, and improve the reservoir - encounter rate and single - well production.
IV. Related to Downhole Instruments and Tools Ultra - High - Temperature - Resistant Downhole Instruments and Tools With the progress of technology, the temperature - and - pressure - resistance capabilities of downhole tools, instruments, and materials continue to improve. In the future, it is expected to exceed 230 °C or even 300 °C, which will promote the oil and gas exploration and development of deep and ultra - deep wells and the development and utilization of high - temperature geothermal energy.
V. Related to Drilling Technologies Intelligent Drilling Composed of intelligent drilling rigs, downhole intelligent - guidance - drilling systems, etc., it realizes closed - loop control. Intelligent - drill - floor robots and intelligent - pipe - handling robots with machine - learning capabilities will replace some manual operations. Key operations such as geosteering can be remotely controlled. Cooperating with super - bits to carry out horizontal - well super - one - trip - drilling is expected to reduce drilling costs. It is expected to enter the initial stage of intelligent drilling in 2025, which will have a profound impact on the drilling industry. Continuous - motion Intelligent Drilling Rig It has the characteristics of continuous tripping, continuous casing - running, continuous circulation, and continuous feeding, which improves the efficiency and safety of tripping and casing - running. It has been field - tested. If it is put into commercial application, it will become a new - generation drilling rig, representing a new revolution in drilling - rig technology. In the future, after the introduction of artificial intelligence, the operation efficiency and safety will be further improved. Double - wall - pipe Reverse - circulation Drilling Technology By making the drilling fluid reverse - circulate in the pipe - in - pipe, the cuttings - bed problem is eliminated, which is beneficial to reservoir protection. The pipe - in - pipe also serves as an electricity and data - transmission channel, realizing pressure - controlled drilling throughout the whole process, reducing non - production time, and improving operation safety. It has been tested on - site many times. If it is put into commercial application, it will be a major breakthrough in drilling technology. The continuous development and application of these new technologies in oil and gas exploration and development will inject new vitality into the sustainable development of the oil and gas industry and promote oil and gas exploration and development to a new level.
