Fine Modeling of Multiscale Fracture Cavity Fusion in Fault Solution Reservoirs Based on Multiscale Discrete Crack Modeling Method.

Geological modeling is a three-dimensional (3D) representation of comprehensive geological research results in oil fields. In this paper, first, the comprehensive geological research results were fully applied to establish geological models such as matrix, reservoir, and fractures in the study area. Second, in response to the geological characteristics of carbonate fractured and vuggy reservoirs, various data are integrated. Finally, by collecting and organizing various basic data mentioned above, a refined geological model of the oil reservoir in the study area is established. Results show that (a) Due to the complexity of the distribution of cracks and pores, the presence of these unrelated grids also affects the observation of target cracks and pores. (b) There may be multiple adjacent nodes in the initial access node. The strategy of depth-first traversal is to first access the first adjacent node. (c) There is a significant difference between the connected units extracted solely from static data and the connected units reextracted after fine-tuning the crack position considering dynamic data.

Study on Reservoir Characteristics and 3D Spatial Carving of Fault Solution Reservoirs Based on Geophysical Methods.

At present, research studies on the description of fracture characterization elements in fault solution reservoirs are relatively limited, and further research is needed on contour recognition and characterization methods. In this paper, first, the regional fault system is investigated and the faults are finely identified and characterized. Second, the volume of contour-sensitive attributes of the fault solver is optimized using tensor attributes, amplitude variation, discontinuity detection, and other attributes. Finally, a comprehensive evaluation of the fault solution reservoir is carried out by combining the dynamic production characteristics. Results show that (a) the interior details of fractured reservoirs can be mainly divided into two categories: cave-type reservoirs and fracture-pore-type reservoirs. (b) Fractured and porous reservoirs mainly utilize discontinuous properties and combine well data to calibrate and determine threshold values, ultimately achieving the characterization of interior details of fractured solution bodies. (c) After anisotropic diffusion filtering and fault enhancement, the seismic data was subjected to amplitude gradient disorder detection attribute calculation for multiscale fractures.

Study on the Significance of Folate Receptor-Mediated Staining Solution (FRD) Staining in Screening High Grade Cervical Lesions.

BACKGROUND The aim of this study was to investigate the significance of folate receptor-mediated staining solution (FRD) in examination of cervical lesions during gynecological examination. MATERIAL AND METHODS A total of 404 patients participated in this study. FRD staining was applied to screen high grade cervical lesions. ThinPrep cytology test (TCT) and human papillomavirus (HPV) testing were also used for screening high grade cervical lesions. Coincidence rate and KAPPA value of different methods were compared by SPSS software. RESULTS As for CIN2+ and CIN3+, sensitivities for HPV testing were (96.92% and 97.78%) >TCT classification 1 (90.77% and 91.11%) >FRD staining (80.00% and 86.67%) >TCT classification 2 (70.77% and 77.78%), respectively. While specificities for HPV testing were (7.08% and 6.44%)
