A Review of Numerical Simulation and Connectivity Analysis in Complex Media Reservoirs
Abstract: Artificial intelligence and deep learning are becoming increasingly important in oil and gas field development, gradually becoming the development trend and research hotspot in the petroleum industry. Currently, over 70% of large oil and gas enterprises worldwide have listed the “physical-data dual-driven” model as their core strategy to make up for the shortcomings of pure data-driven models in generalization with small samples. This article focuses on the combination of the three major algorithms (CNN, RNN, and R…

A Numerical Study of Hydraulic Fracture Growth Under One Cyclic Injection
Abstract: In this paper, a more potential cyclic fracturing scheme, which alternates injection and flowback in each injection cycle, is proposed to promote the stimulation efficiency. Collection and Re-injection of all the flowback fluid into formation to create fractures in the following cycles achieves environmental sustainability. With 2D displacement discontinue method, we model the dynamic behavior of a bi-wing fluid-driven fracture symmetrically emanated from a circular wellbore under the proposed cyclic injection sche…

Numerical Simulation and Sensitivity Analysis of Key Parameters for Modified Silicon-Based Nanoparticle Enhanced Oil Recovery in Low-Permeability Reservoirs
Abstract: To solve the low recovery rate of low-permeability heterogeneous reservoirs in mid-late oilfield development, this study focuses on modified silicon-based nanoparticle EOR technology (strong migration, good environmental compatibility). A 3D two-phase two-component model was built via CMG-STARS (single-well homogeneous & single-injection four-production heterogeneous scenarios). Sensitivity analysis of 5 key parameters (injection concentration/rate/timing, reservoir permeability/porosity) was conducted by orthogona…

Study of Methane Hydrate Phase Transition and Multiphase Flow Characteristics: Effect of Pressure and Initial Hydrate Saturation
Abstract: Hydrate reservoirs often experience phase transitions such as decomposition and reformation during production process, which can significant fluid flow and reduce gas recovery efficiency. To reveal the mechanism between hydrate phase transition and gas–water two-phase flow behaviors, a visualized experimental setup was developed to monitor hydrate phase transition characteristics under different initial pressure and saturation conditions during the multiphase flow process. The experimental results indicated that in…

Study on High-Performance Prediction of Wellbore Multiphase Flow Pressure Drop Distribution Based on Artificial Neural Networks
Abstract: This paper constructs a proxy model to predict the pressure drop distribution in wellbore multiphase flow based on artificial neural networks (ANNs). 10,000 sets of high-quality samples involving 15 parameters involving wellbore multiphase flow and covering diverse working conditions were generated based on the Beggs-Brill algorithm, which ensures the physical consistency of data and the comprehensiveness of working conditions; two ANN models were constructed to realize the bidirectional nonlinear mapping from well…
