[Retracted] High‐Temperature‐Resistant, Clean, and Environmental‐Friendly Fracturing Fluid System and Performance Evaluation of Tight Sandstone

Abstract

Hydraulic fracturing, as an oil-water well stimulation and injection technology, is particularly important in the production and stimulation of low-permeability oil and gas fields, and the performance of the fracturing fluid directly affects the success of the fracturing operation. Compared with traditional water-based fracturing fluids, clean fracturing fluids have the advantages of strong sand-carrying ability and easy gel breaking with no residue. Aiming at the problem of poor temperature resistance and shear resistance of the clean fracturing fluid, based on previous research, this paper selects a high-temperature-resistant clean fracturing fluid system and evaluates the performance of the system. The research results show that the system has better rheological properties, better sand-carrying performance, shorter gel-breaking time, and less damage to the reservoir.

A Study on English Translation Skills and Modes of Multimodal Network from the Perspective of Teaching Situation

“…At the same time, he also pointed out that multimodal network resources in English translation skills must be used properly, otherwise it will backfire [17]. Wang et al pointed out that in order to improve teaching efficiency in the teaching of legal English translation skills, different modes such as pictures, recordings, videos, film clips, real objects, and court props should be comprehensively used to organize teaching; various communication modes should be fully used; various modern educational technology means should be flexibly used; and the synergy and reinforcement between different modes should be fully brought into play, so as to organize teaching in a multimodal network as real as possible, so as to improve the teaching effect and promote students' internalization of what they have learned [18].…”

Target Recognition Technology of Multimedia Platform Based on a Convolutional Neural Network

“…From the earliest R-CNN model to Fast-RCNN to the later Faster-RCNN, the R-CNN model has been continuously developed into a series, and these series all belong to the category candidate regions. R-CNN is the first algorithm to apply CNN, and such ability of CNN to extract features is outstanding, which significantly improves the effect of target detection and recognition [21].…”

Application of Media Integration in the Construction of Scientific and Technological Innovation Ecological Chain

“…However, due to the inertia of the planned economy in the scientifc research system, research in scientifc research institutes and universities is often selfcontained. Since research and production belong to diferent units, the goals of the two are inconsistent, and research and production are often disconnected, resulting in "market failure," the embarrassing situation of "two skins" in the economy and technology is not conducive to the implementation of the innovation-driven development strategy [21].…”
