Abstract In gas drilling operations, the rate of penetration (ROP) parameter has an important influence on costs. Prediction ROP can optimize operational parameters and reduce its overall cost. To predict with satisfactory precision, a stacked generalization ensemble model is developed in this paper. Drilling data were collected from shale survey well Xinjiang, northwestern China. First, Pearson correlation analysis used for feature selection. Then, Savitzky-Golay smoothing filter to noise...
The channel fracturing technique has been proven to provide much higher conductive fracture networks by placing discontinuously proppant inside packs. Despite the great success of this new technique, there is still a lack models and methods characterize non-uniform placement heterogeneous permeability distribution within stimulated-reservoir-volume (SRV). In article, dual-porosity model coupled with tri-linear flow quantify production performance fractured horizontal wells. As consequence...
In this paper we focus on the technique to construct and visualize individual tooth model from CT image sequences for dental diagnosis treatment. For images teeth are touched with each other in some slices. We have find region separate two if they together. propose method based distinguish feature of oral cavity structure. utilize full 3D data instead 2D projections which may lose information. firstly upper lower regions then fit arch using fourth order polynomial curves after a series...
Under the background of education reform, colleges and universities should pay attention to construction college programmes explore a feasible path based on OBE concept. This paper takes exploration practice efficient Civics course concept as research content, firstly, introduces concepts Civics, then proposes from perspectives collaborative planning design, positive implementation, continuous optimisation, finally draws corresponding conclusions, hopes that in this provides theoretical...
In the dental field, 3D tooth modeling, in which each can be manipulated individually, is an essential component of simulation orthodontic surgery and treatment. However, computerized tomography slices teeth are located closely together or inside alveolar bone having intensity similar to that teeth. This makes it difficult individually segment a before building its model. Conventional methods such as global threshold snake algorithms fail accurately extract boundary tooth. this paper, we...
To achieve safety, high quality, and efficiency in deep drilling, it is necessary to get formation drillability around the borehole during drilling-trajectory planning intelligent drilling control. Since data have characteristics of low value density noise process difficult model drilling. In this paper, a new online modeling method for based on sequential nadaboost extreme learning machine (OS-Nadaboost-ELM) algorithm has been proposed. Firstly, well logging parameters are chosen as inputs...
We focus on the technique to construct and visualize individual tooth model from CT image sequences for dental diagnosis treatment. One challenging problem images is that crown regions are touching with other teeth in some slices. The common boundary two adjacent missing. propose a coupled variational level set method region competition of generate virtual them. Moreover presents un-uniform intensity leads suspicious inner edges. use normal direction evolving contour gradient determine true...
Hydraulic fracturing optimization is very important for low permeability reservoir stimulation and development. This paper couples the treatment with fracture geometry in order to maximize dimensionless productivity index. The optimal dimensions conductivity, given a certain mass or volume of proppant, can be determined by Unified Fracture Design (UFD) method. When solving propped length width, should first. However, they vary according proppant concentration cannot obtained advance....
The hydrocarbon deposits have stimulated worldwide efforts to understand gas production from hydrate dissociation in reservoirs well. This paper deals with the potential of hydrates as a source energy which is widely available permafrost and oceanic sediments. It discusses methods for natural hydrates. Authors provide detailed methodology used model productivity recovery reservoir mathematical modelling tool evaluating production. simulation results show that process sensitive function...
Under the limitation of rockets carrying capacity, rated torque and power offered by drilling rigs, Therefore, optimizations auger driller's structure size parameters are necessary to realize deep lunar coring under qualified condition. Study results indicate that bit inner diameter is determined target sampling mass density objects. Outer diameters helical blades required for restart from its state buried. To utilize accommodated capacity cuttings dissipating heat produced during process as...
