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 ...

Objective Systemic lupus erythematosus (SLE) is a heterogenous inflammatory condition with widely varying global prevalence estimates. The frequency of SLE in the general population of Australia has been reported to be notably lower than contemporary estimates in countries such as the United States or United Kingdom, at 19 to 39 per 100,000 as opposed ...

Optimization of horizontal well refracturing technology in tight reservoirs
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 ...

Objective We aimed to estimate the prevalence and cumulative incidence of hydroxychloroquine retinopathy (HCQ‐R) and its risk factors among patients receiving long‐term HCQ with rheumatic diseases through a systematic review and meta‐analysis of observational studies that used spectral‐domain optical coherence tomography (SD‐OCT) for screening ...

A method for analysing fluid structure interactions on a horizontal axis tidal turbine
Free stream tidal turbines are rotating bodies in fast flowing tidal currents, and as such are exposed to fluctuating loads from the surrounding fluid.

Objective The concern that nonsteroidal anti‐inflammatory drugs (NSAIDs) may precipitate flares of inflammatory bowel disease (IBD) has limited their use in managing musculoskeletal symptoms in those with IBD, but safety data are mixed. Methods This retrospective cohort study included patients with IBD aged at least 18 years from Optum's deidentified ...

Enhanced visualisation of complex thermofluid data: Vertical and horizontal combined convection and microscale heat transfer cases [PDF]
Copyright @ 2000 UITIn general, convective heat transfer is an 'n-dimensional' problem where n is well in excess of 3 for steady flows. Traditionally, the method of dimensional analysis results in a small number of dimensionless groups.

Immunosuppressive Drug Use in Limited Systemic Sclerosis: An International Survey
Objective Current guidelines recommend immunosuppressive treatment for diffuse cutaneous systemic sclerosis but are less clear on their use in limited cutaneous systemic sclerosis (lcSSc) in the absence of internal organ complications. We conducted an international survey to understand current immunosuppressive drug prescribing patterns in lcSSc ...

The stability criteria affecting the formation of high‐entropy alloys, particularly focusing in supersaturated solid solutions produced by mechanical alloying, are analyzed. Criteria based on Hume–Rothery rules are distinguished from those derived from thermodynamic relations. The formers are generally applicable to mechanically alloyed samples.
