Application of multi-information fusion modeling of fracture-vuggy reservoir in Ordovician reservoir of 12th block in Tahe Oilfield

Ultra-deep (7500–9000 m) Ordovician tight limestone heterogeneous fractured-vuggy reservoir is an important target of FuMan Oilfield in Tarim Basin. The strike-slip fault controlled reservoir is related to formation fracture and dissolution caused by geological stress. The seismic wave-field anomaly characteristics with different energy and irregular waveform are displayed in the seismic profile. Accurate identification of fractured-vuggy reservoirs wrapped in tight limestone is the direct scheme to improve production efficiency. Therefore, a new combination method flow of seismic wav

Shallow shale gas enrichment model of Taiyang-Haiba in Zhaotong demonstration area

Pore and its structural characteristics are key parameters affecting shale gas reservoir development. Accurate quantitative characterization of shale pore and its structural characteristics is of great significance for evaluating shale reservoir state. In this study, 15 shallow marine shale samples were collected in Well Y108. X-ray diffraction results indicate that brittle minerals are the most common components in shale. In this paper, various pore types are classified and characterized by scanning electron microscope images. The total porosity of shale measured by the mercury intrusion m

Optimum hydrothermal synthesis conditions of carbon fixing mineral-dawsonite

This paper summarizes specific features of supercritical hydrothermal synthesis of metal oxide particles. Supercritical water allows control of the crystal phase, morphology, and particle size since the solvent's properties, such as density of water, can be varied with temperature and pressure, both of which can affect the supersaturation and nucleation. In this review, we describe the advantages of fine particle formation using supercritical water and describe which future tasks need to be solved.

Fast least-squares reverse time migration based on cycle-consistent generative adversarial network

Reverse-time migration of multiples can generate imaging results with wider illumination, higher folds, and broader wavenumber spectra than the conventional migration of primaries. However, the results of the migration of multiples retain heavy crosstalks generated by interactions between unrelated multiples, thereby seriously degrading imaging qualities. To eliminate such crosstalks, we propose a least-squares optimized algorithm of multiples. In this method, different-order water-column multiples and water-bottom-related multiples are extracted using multiple decomposition strategies befo

Reaction kinetics of sodium nitrite and ammonium chloride system considering conversion rate

Aiming at the problem that the existing NaNO 2 /NH 4 Cl reaction kinetic equation that does not consider the conversion rate of reactants is difficult to effectively predict the heat/nitrogen generation situation, the experimental test analysis method is used to explore the H + concentration limit and reaction conversion rate of nitrogen generation reaction. The gray relational analysis method was used to study the influence degree of each factor; the Newton-Raphson iterative method was used to calculate the reaction kinetic parameters of the reaction conversion rate, and the prediction met
