In-memory computing establishes a new and promising paradigm aimed at solving problems caused by the von Neumann bottleneck. It eliminates need for frequent data transfer between memory processing modules enables parallel activation of multiple lines. However, vertical storage is generally required, increasing implementation complexity SRAM writing mode. This article proposes 10-transistor (10T) to omit improve stability in-memory computing. A cross-layout word line arrays with multirow or...
Abstract Measuring oil well production is a fundamental task in oilfield operations and development. Precise measurement results are vital for diagnosing anomalies, assessing field development, optimizing operating conditions. Currently, the majority of oilfields depend on metering stations measurement, costly labor-intensive approach with limited automation. Similarly, methods based indicator diagrams also face challenges due to substantial errors. To improve efficiency accuracy pumping...
Conventional gas well classification methods cannot provide effective support for routine management, and suffer from poor timeliness. In order to guide the on-site operation in liquid loading wells improve timeliness of classification, this paper proposes a production data-driven method based on LDA-DA (Linear Discriminant Analysis–Discriminant Analysis) combination model. method, considering requirements are evaluated two aspects: drainage capacity (LDC) intensity (LPI), classified into...
Abstract Liquid loading poses a prevalent challenge in gas well production. To maximize the production rate and reduce cost of deliquification, intermittent is often applied. However, optimization operation parameters remains challenging due to transient behavior reservoir-wellbore system. In this study, efficient algorithms are proposed automatically optimize real-time remove liquid efficiently maintain production, through which recovery factor can be extended. Firstly, we build...
Swift heavy ions delivered by Heavy Ion Research Facility at Lanzhou(HIRFL) were used to bombard the 32k SRAM IDT71256 angles from 0°—85°. The multiple bit upset(MBU) ratio can reach as high 70% when device was tested with 15.14MeV/u 136Xe or large 36Ar ions. angular effect of cross section is mainly due occurrence MBU especially angles. determined energy deposited in whole sensitive layer and that more than two upset increased incident angle.
Particle size is an important factor affecting the Thermal-Hydraulic-Mechanical (THM) coupling behavior of graveled rock mass, especially for shear mechanical properties. In this study, three groups particle range and nine grading samples are designed a large-scale direct test. The relationships between stress displacement, strength, ratio, strength parameters, breakage pebble gravel analyzed. influence grade on material discussed. Results show evident in process shear, degree fragmentation...
Trilinear flow model is an effective method to reproduce the behavior for horizontal wells with multistage hydraulic fracture treatments in unconventional reservoirs. However, models developed so far transient analysis have rarely considered inflow performance of wells.

Nanographene oxide (NGO) is currently being explored for various biomedical applications.However,little information known about its biological behaviors in vitro and vivo.For further studying pharmacokinetics related living systems,an effective convenient tracing method particularly demanded.In this work,NGO was labeled with radionuclide 188Re (188Re-NGO).To obtain high labeling yield purity,a number of conditions,including concentration SnCl2 ascorbic acid,reaction time temperature,and pH...
Abstract Fuling shale gas is the first commercialized block in China, and more than 30 billion m3 of has been produced. To achieve yearly production target 7 m3, infill wells have drilled completed. This raised a big concern on balance hydraulic fracturing job size well negative fracture interference parent wells, especially for complex very heterogenous reservoir due to multiple tectonic evolutions. A multidisciplinary team across five domains was formed turn completion design based...
