for the characteristics of horizontal fractures in shallow low-permeability oil layers after hydraulic fracturing in multilayer reservoirs, horizontal fractures are taken equivalent to an elliptical cylinder with the reservoir thickness using the equivalent permeability model; then, upon the elliptic seepage theory, the seepage field which has led by a vertical well with horizontal fractures is...

We investigate the effect of different saturation histories relevant to various oil displacement processes (including secondary and tertiary gas injections) on three-phase gas/oil/brine relative permeabilities of water-wet sandstone. It is found that three-phase water (wetting phase) relative permeability is primarily a function of water saturation and shows no dependency upon saturation histor...

The ultra-low permeability, thin layer and low abundance GLN area is developed by waterinjection with horizontal straight combined well pattern. With the extension of development time, water appears in multiple sections directions Wells, gradually enters stage medium high cut, which shows characteristics rising when injected, falling liquid stopped, limiting profile control pressure rounds Well...

The southern part of Jin45 fault block is a low permeability layered reservoir with thin oil layer thickness. And the development horizontal well pattern has good economic benefit in block. distribution quite different. main stable, but non-main unstable. In this study, through engineering method and numerical simulation method, direction, form, spacing length are optimized to determine layer. ...

A block in Daqing Saltu Oilfield has a large span of formation systems, permeability grade difference, prominent inter-formation conflicts, low degree control multi-directional water drive, injection and extraction well spacing thin differential layers, utilization, etc. In this regard, based on the existing network, study reconstruction system network is carried out area. Longitudinal subdivis...

Foam flooding (or injection of foam) is a common technology to enhance oil recovery. Although the effects of permeability on foam flooding were well studied in many laboratory experiments, little research has been focused on the specificity of low permeability. In this paper, a series of constant-quality nitrogen foam flow experiments were conducted to investigate the effects of permeability on...

We use a three-dimensional mixed-wet random network model representing Berea sandstone to compute displacement paths and relative permeabilities for water alternating gas (WAG) flooding. First we reproduce cycles of water and gas injection observed in previously published experimental studies. We predict the measured oil, water and gas relative permeabilities accurately. We discuss the hysteres...

This paper mainly provides the well and layer selection method of fracturing displacement. It solves problem insufficient formation energy lack forming effective communication between oil water wells, resulting in poor injection capacity thin-and-poor layers, production capacity, deficit seepage capacity. The research includes following two parts. (1) Target wells were optimized by selecting th...

Omega-3 rich fish oils are extremely labile, thus requiring control of oxidation and off flavor development. A recently proposed emulsification method, layer-by-layer (LbL) deposition, was found to be a plausible method to enhance the characteristics of bioactive ingredients, especially lipids. The present work was designed to test the possibility of enhancing the uptake and utilization of omeg...
