Mathematical analysis of structural fracture scale in shale based on core fracture observation of the second member of Kongdian Formation in Cangdong Sag

Taking the structural fractures in the Kong 2 Member shale of the Cangdong Depression as the research object, we focused on using core data and using core observation, mathematical analysis and software fitting to carry out fracture type identification, structural fracture scale calculation and analysis of influencing factors. and other research work. Based on the measured data of structural fractures on the shale core of the Kong 2 Member, the ellipse fitting method based on the least squares method was used to establish the elliptical standard equation of the longitudinal and horizontal s

Investigation on dynamic mechanical behaviors and energy consumption of conglomerate under three-dimensional static stress

The rocks at the bottom of the drilling hole in the huge thick gravel layer in the Kuqa piedmont of the Tarim Oilfield are in a complex load state of impact and in-situ stress., is the main problem restricting the drilling efficiency in this block. Exploring the dynamic load characteristics and energy consumption rules of conglomerate under three-dimensional stress conditions is the key to increasing the speed of rock breaking in the gravel layer. Analysis through the true triaxial Hopkinson pressure bar test The dynamic load strength and deformation characteristics of conglomerate under mo

Structure characterization technology and application of well seismic matching under dense well pattern in oilfield

Old oilfields with ultra-high water content have a dense well network, and efficient tapping of remaining oil requires finely describing the structure distribution characteristics in three-dimensional space. The advantages of the two methods of oilfield data information characteristics, development needs, and structural interpretation and structural modeling in structural characterization are as follows: Based on the analysis of deficiencies, a method for well-seismic matching structural characterization is summarized. The method includes well-seismic calibration and layer interpretation in

Numerical simulation and dynamic characteristics of drainage and production in high density bedding shale oil reservoirs

By establishing a connection between the characterization parameters of shale lamination fractures and the characterization parameters of the dual media model, the dual media model is The shape factor, equivalent porosity and equivalent permeability are characterized by two parameters: lamination fracture density and lamination fracture opening. The dual media model is used to characterize the highly developed lamination fractures and establish multi-stage fracturing water Flat well dual medium model. Use local grid densification to represent discrete fractures, high pressure and high water

Influence of asphalt composition on stability of emulsified asphalt

Five kinds of matrix asphalt were selected to measure the basic properties of different asphalts and the stability of emulsified asphalt. Analysis methods such as four components, infrared spectroscopy, elemental composition, and nuclear magnetic resonance were used, combined with linear correlation and gray correlation entropy analysis methods to study the asphalt. The influence of composition on the stability of emulsified asphalt. The results show that the higher gum content, gum/asphaltene ratio, oxygen content and aromaticity fA in the matrix asphalt is beneficial to the stability of t
