Optimization of the Fracture Parameters of Fractured Horizontal Well of Horizontal Well-Vertical Well Joint Development Well Pattern

Open Journal of Natural Science, 2016
由于水平井钻井技术的飞速发展，水平井–直井联合开发技术已经逐渐成熟，然而在设计油田开发方案和油藏工程计算时，对于压裂水平井–直井联合开发井网压裂水平井参数的优化还比较少。本文依据大庆某外围低渗透薄层水平井–直井联合开发油田的地质特征和开发特征，应用油藏数值模拟Eclipse软件并采用LGR局部加密网格技术建立了具有代表性的机理模型，从而对水平井–直井联合开发井网压裂水平井的参数进行优化，研究结果为类似水平井–直井联合开发油田压裂水平井参数优选提供了指导。 Due to the rapid development of horizontal well drilling technology, Horizontal well-Vertical well joint development ...

Modern Management of Asymptomatic Carotid Stenosis: A Meta‐Analysis of CREST‐2, SPACE‐2, and ECST‐2

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Background Recent randomized trials (CREST‐2, SPACE‐2, and ECST‐2) have compared carotid revascularization (carotid endarterectomy [CEA] or carotid artery stenting [CAS]) plus contemporary medical therapy (CMT) versus CMT alone in asymptomatic carotid stenosis.

Global Rather Than Vertical‐Selective Saccadic Abnormalities in Progressive Supranuclear Palsy

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective To test whether vertical saccades are preferentially affected in Progressive Supranuclear Palsy (PSP). Methods PSP patients (n = 24) were compared to age‐matched controls (n = 94) and two degenerative groups (Alzheimer's disease, n = 20; Lewy body disease, n = 50).

Validation of a Cellular Imaging‐Based Method as a Potential Biomarker for SPG4 Hereditary Spastic Paraplegia

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Background Hereditary Spastic Paraplegia (HSP) comprises a group of rare genetic diseases characterized by length‐dependent axonal degeneration of the corticospinal tracts and dorsal columns, whose main clinical feature is spastic gait. Pathogenic variants in the SPG4 gene cause Spastic Paraplegia Type 4 (SPG4‐HSP), the most common form of HSP.

CSF Cytokine Network Organization Predicts Progression Independent of Relapse and MRI Activity in Multiple Sclerosis

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Progression independent of relapse activity is a major determinant of long‐term disability in multiple sclerosis, but its immunopathologic basis remains incompletely understood. We investigated whether relapse‐independent progression in radiologically stable relapsing–remitting multiple sclerosis is associated with distinct ...

Impact of Age on the Diagnostic Yield of Routine EEG in People With Childhood or Juvenile Absence Epilepsy: A Cross‐Sectional Study

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Background We aimed to identify the proportion of individuals with a confirmed diagnosis of childhood absence epilepsy (CAE) or juvenile absence epilepsy (JAE) who show a negative routine EEG (rEEG), and to determine the main factors associated with this finding.

Optimization of horizontal well refracturing technology in tight reservoirs

Youqicang pingjia yu kaifa, 2018
In order to improve the refracturing effects of the tight reservoirs and the economic benefits, we provided the optimization methods for the well and layer selection and fracturing design in the refracturing process of the tight wells: the multi-level ...
