The mechanism and problems associated with development engineering of fire-flooding in post-steam-injected heavy oil reservoirs was studied using 1D & 3D physical simulation experiments reservoir numerical simulation. temperature combustion zone decreased high-temperature enlarged because there existed secondary water formed during steam injection, which could absorb carry heat towards producers out the front fire flooding, but high saturation layers caused by had less influence on quantity...
The propagating characteristics of combustion fronts and coke zones in the assisted gravity drainage process were studied using 3D physical simulation experiments. main mechanisms factors affecting stable propagation discussed. experimental results show that front can be divided into startup stage, radial expands stage moving forward stage. top oil layer is ignited first at Ignition temperature, ignition time air injection rate are key parameters for successful ignition. At expanding grows...
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)...
Summary An ultraheavy oil block is undergoing a dry in-situ combustion field test in the Xinjiang fields, China. However, this method faces problems of high air/oil ratio and low production rate. Researchers are exploring feasibility using wet to improve economic efficiency For purpose, it necessary study displacement characteristics water/air (WAR) limit reservoirs. In study, we investigated differences between by conducting 1D model tests. The results show that can transfer heat from...
Abstract LKQ oil field is a super-deep heavy reservoir with the dead viscosity of 9,680~12,000mPa.s at 50?, depth 2,100 m~3,200 m and temperature 60~95°C. High low flowability result in production rapid decline primary development. The steam injection, as its thermal efficiency, not suitable for reservoir. In situ combustion promising recovery process which energy generated inside However, has more than 2000m, no such high applied pressure all over world. For reasons, it decided to study...
Purpose: To devise an efficient strategy for the separation and recovery of high-quality γ-PGA by investigation physical properties, pigment properties microfiltration mode high-viscosity fermentation broth.Methods: The bacterial strain, Bacillus subtilis 115, was used in this study. viscosity broth determined digital viscometer with spindle SP-2 at 25 oC. concentrations glucose L-glutamate were analyzed a biosensor equipped both oxidase Lglutamate electrodes. liquid scanned UV...
A field test in the Xinjiang oilfield China shows that viscosity of heavy oil has a certain influence on combustion dynamics and injection-production performance fire flooding. The experiment this study uses one-dimensional tube to temperature, gas composition, air injection pressure production flooding with different viscosities. results show viscosities 1180–22500 mPa·s can achieve stable combustion, O2 content produced during stage is <0.5%. higher oil, temperature burned zone smaller...
Abstract Toe-to-Heel-Air-Injection (THAI™) is an in-situ combustion process that used for the recovery of bitumen and heavy oil. It combines a horizontal production well with vertical air injection placed at toe. The drainage mechanism THAI similar to SAGD - pattern. However, it much more difficult control compared as gas flow liquid coexist in THAI. start-up front expanding characteristic require critical attention, order ensure optimal operation. temperature profiles post-mortem pictures...
Summary Certain ultraheavy oil reservoirs with depths approaching 1000 m feature wide well spacing. After cyclic steam stimulation (CSS), cold zones high residual saturation exist between wells. This leads to a at the front during subsequent steamflooding process, which in turn results injection pressure. The simultaneous of CO2 and into formation can optimize pressure enhance utilization efficiency. A majority laboratory-based experimental studies have reported favorable outcomes...
Bacillus subtilis Bs-115 was isolated from the soil of a corn field in Yutai County, Jinan City, Shandong Province, People's Republic China, and is characterized by efficient synthesis poly-γ-glutamate (γ-PGA), with saccharification liquid as sole energy carbon source during process γ-PGA formation. Here, we report complete genome sequence genes associated synthesis.
