Abstract Alkali–surfactant–polymer (ASP) flooding is a chemical enhanced oil recovery method; its working mechanisms include mobility control, wettability alteration, and in‐situ emulsification. However, conventional alkalis used in the ASP could cause some serious issues, including scaling, formation damage, pipe corrosion. In this study, we investigated feasibility of incorporating organic as additives hot water to enhance heavy recovery. The focus was on studying interfacial properties,...
The miscibility of flue gas and different types light oils is investigated through slender-tube miscible displacement experiment at high temperature pressure. Under the conditions pressure, oil possible. At same temperature, there a linear relationship between efficiency increases gently then rapidly to more than 90% achieve with increase temperature. rapid closely related process that components transit in phase state due distillation rise Moreover, lighter oil, lower minimum which allows...
Sand-conglomerate reservoir has been scarcely studied, and there is no effective method available for quantitative characterization of pore structure such a reservoir. In this paper, multifractal study was made on the Triassic Karamay Formation sand-conglomerate in Mahu rim region, Junggar Basin, by using variety high-resolution analysis methods, as Micro-CT, QEMSCAN, MAPS, order to quantitatively characterize heterogeneity size distribution, relative differentiation large small pores,...
The development of steam chamber can be used to evaluate steam-assisted gravity drainage (SAGD) performance. velocity expanding is the key parameter for evaluating chamber. Based on SAGD technology theory and heat transfer theory, two calculation model methods, observation well temperature method edge estimating horizontal chamber, were presented. Through analyzing monitoring data numerical simulation results a typical super heavy oil block developed by in Fengcheng oilfield Xinjiang, NW...
The formation of facial arteriovenous fistula (AVF) directly between the artery and vein after trauma is very rare. Compared with intracranial AVF, understanding this condition limited. This paper reported case a 49-year-old male who had metallic foreign object impaled on his left neck while weeding 6 months prior to admission. However, 3 admission, he developed gradual throbbing swelling side face. Auscultation revealed vascular murmur in front mandibular angle Digital subtraction...
With the 3a pilot area in Block H1 of Xinjiang Oilfield as an example, a basic model for accurate numerical simulation fire flooding is established combining with physical and field performance, after oil components are divided reasonably, high temperature combustion formula defined. This used to trace simulate H1. The main results follows: (1) secondary water generated steam injection mostly displaced by flue gas during initial phase, only small fraction works limited wet combustion; (2)...
Microbial metabolic products, such as biosurfactants, bioemulsifiers, acids, solvents, and biogases, are useful for reducing the viscosity of heavy oils enhancing oil recovery. Two viscosity-reducing microorganisms, namely, SH-2 SH-3, were selected from produced water which collected high-temperature reservoirs by enrichment culture technique. The screened bacteria produce biosurfactants biogases that can biodegrade crude components. combined with indigenous applied in a pilot test microbial...
Heavy oil emulsions such as water in (W/O), (O/W), and (W/O/W) would be formed during the development of heavy reservoirs. The key to efficient reservoirs is clarify fluidity formation pores medium. In this study, main factors that determine emulsion were analyzed under condition simulating reasons for difference between viscosity medium measured by laboratory rheometer analyzed. Then, experiments have confirmed shortcomings current screening evaluation method emulsified reducer. Finally,...
Viscosity-reducer flooding is an effective method to improve oil recovery after the water of heavy oil, and water-in-oil emulsion (W/O emulsion) easily formed during this process. W/O has a strong ability mobility ratio block off high permeability layers, which can effectively sweep coefficient enhance recovery. The microscopic visual glass model mainly used study displacement mechanism dilute oil; however, there are few studies on emulsification influencing factors oil. purpose paper caused...
Abstract Conventionally, the start-up method of dual-horizontal wells SAGD is steam circulation. During circulation phrase, minimum time and maximum heat communication uniform profile are expected to achieve high oil production. Generally, phrase takes 2 3 months in Canada quality reservoir. For poor reservoir, will be longer, for example, China it 200-300 days. In order solve disadvantages about longer preheating ununiformity conventional method, electric researched, super-longer integrated...
Summary The problems of oil/steam ratio (OSR) and oil production decline are prominent during the middle/later stages steam-assisted gravity drainage (SAGD) in superheavy reservoirs. Using noncondensable gas (NCG) by SAGD can reduce heat loss to overburden carbon dioxide (CO2) emissions. However, date, laboratory experiments have mainly been conducted simulate NCG coinjection with steam early stage SAGD. There has limited research on into mature chamber. For this study, five sets 2D physical...
Abstract The barriers in oil reservoir have great effect on SAGD production. Due to wide existence of interlayers, steam chamber can not move upward freely perspective development, and also leads a longer production cycle so as increase the investment risk. Firstly author studied distribution formation reasons muddy Zhong 32 Windy City oilfield. Steam developing characteristics breakthrough pattern are by temperature detection data, historical data microseismic fitting dynamic binding static...
Based on the engineering geological data of a nuclear power plant site, nine profiles were created with hard interlayers different thicknesses. The equivalent linearization method seismic motion segment‐input used for one‐dimensional nonlinear response analysis was applied to study effect interlayer thickness peak acceleration and spectra site response. results showed that there an obvious influence responses. With increase thickness, responses decreased. Under same interlayer, strengthened...
