Based on the data of mud logging, well logging and seismic data, the erosion thickness and original sedimentary thickness of the Middle-Late Triassic prototype basin in the west of Turpan-Hami Basin-Zhundong area were restored and analyzed. The erosion thickness of the Middle-Upper Triassic was calculated by the seismic stratigraphic thickness trend method, and the prototype basin was analyzed by combining the original sedimentary thickness. The results show that the erosion thickness in the west of Turpan-Hami Basin is 0m-600 m, which decreases first and then increases from north to south and then decreases. The erosion thickness of the Middle-Upper Triassic strata in the Zhundong area is 0m-400m, which increases first and then decreases from south to north. The maximum original thickness of the Middle-Upper Triassic strata in the western Tuha Basin is 1400 m in the front of the Bogda Mountain, which is thickened from north to south. The original thickness of the Middle-Upper Triassic strata in the eastern Junggar Basin generally increases from north to south. Bogda Mountain and its adjacent areas show a quasi-plainization process of cutting high and filling low. The scope of Taibei depression and Tainan depression further expanded, the sedimentary center moved southward, the Pubei low uplift became the denudation area, and the Keyayi depression and the Toksun depression developed. Beisantai uplift and Shaqi uplift in the north of Zhundong area are developed and their scope is expanding, and Zhundong depression area is developed in the south.

The gas migration mechanism and apparent permeability in shale reservoirs are significantly different from those in conventional gas reservoirs, which is mainly caused by nanoscale phenomena and organic matter as gas storage and supply media. However, in shale reservoirs, gas flow behavior plays an important role in well performance, so it is necessary to develop a new apparent permeability model considering gas transport mechanism. Therefore, in order to study the change of matrix permeability under different pressures in the development process of shale adsorption layer, combined with previous studies, considering the seepage mechanism of stress sensitivity, real gas effect and adsorption, a new model of apparent permeability is created by combining multiple gas transmission mechanisms. The sensitivity analysis of the new model is carried out by changing the corresponding parameters, and the corresponding conclusions are drawn. In this work, the established model can accurately calculate the apparent permeability of viscous flow, Knudsen diffusion and desorption, which makes us have a more accurate understanding of the transmission mechanism of shale gas and contributes to the efficient and sustainable development of shale gas.

Tight sandstone reservoirs are widely distributed in China, because tight reservoirs have the characteristics of low porosity and low permeability, high clay mineral content, etc., it is easy to cause reservoir damage during hydraulic fracturing and is not easy to recover. X-ray whole-rock diffraction analysis was carried out through tight sandstone reservoir core, and the proportion of sensitive minerals in tight sandstone gas reservoir was clarified, and water sensitivity and flow velocity sensitivity damage experiments were carried out based on the test results. The experimental results show that the flow velocity sensitivity damage rate of tight sandstone reservoir is 28.02%, and the critical flow rate is 0.75ml/min, which is a weak flow rate sensitivity injury. The water-sensitive injury rate was 63.98%, which was moderately strong water-sensitive injury.

It has been widely used not only in the fields of big data analysis, automobile automatic driving, intelligent robot and face recognition, but also in various fields of oil and gas industry. Oil and gas production prediction is an important part of reservoir engineering, which is very important for the future production and development of strata, and can give developers some development suggestions. At present, the methods used in oil and gas production prediction are mainly traditional means such as numerical simulation and history matching. With the application of artificial intelligence in various fields of oil and gas industry, the use of machine learning models for oil and gas production prediction has become the direction of development and research.

The physical and mechanical properties, microstructure deterioration characteristics and damage mechanism of natural gypsum rock under freeze-thaw cycles were studied by using a self-developed programmed freeze-thaw experimental device, results showed: Compared with that before freeze-thaw, with the increase of freeze-thaw cycles, the surface dissolution of gypsum rock samples becomes more obvious, the longitudinal wave velocity decreases linearly, the uniaxial compressive strength and elastic modulus decrease exponentially, the compaction stage of stress-strain curve is significantly prolonged, and the plasticity of post-peak failure process is enhanced. With the increase of axial strain, the total input energy curve rises at a faster rate, and the elastic energy curve also rises, but the rising rate slows down significantly after the freeze-thaw cycle, and the dissipation energy curve gradually evolves from a smooth rise to an ' S ' type. The research results have reference significance for the construction scheme design and frost damage prevention of gypsum surrounding rock tunnels in cold regions.

The layered water injection technology based on wave code communication is one of the fourth-generation separated layer water injection technology, widely used in low permeability oil field with pressure operation injection Wells, has the advantages of simple operation and low cost. However, there is a problem of low communication efficiency. In order to solve the problem of low communication efficiency, this paper compares the advantages and disadvantages of amplitude time modulation encoding and pulse position interval encoding, and proposes a method based on pulse position interval encoding and decoding. Finally, the pressure wave communication experiment is carried out. The results show that when the pulse width is set to 5s, the communication time of a set of opening instructions is only 3 minutes, which greatly improves the communication efficiency of the wave coding process. The research on encoding and decoding can provide technical and theoretical support for improving the communication efficiency of layered water injection based on wave code.

In the system, D-limonene was used as the oil phase, and the surfactant CAB-35 and AOS were selected by pseudo-ternary phase diagram method as the surfactant in the ratio of 1:1, and then mixed with n-butanol in the ratio of 1:1 to obtain the best microemulsion effect. The nano emulsion system was prepared by diluting the microemulsion. By testing the interfacial tension, the optimum preparation conditions of nano emulsion were screened. The results showed that the nano emulsion prepared by dilution under the condition of 5:5 oil/water ratio of microemulsion system had the best ability to reduce the interfacial tension between oil and water.
