CO2 flooding has been widely applied in lots of low permeability reservoirs. After extensive CO2 injection,some reservoirs began to show serious gas channeling problems. CO2 foam had been successfully used tosolve gas channeling problems due to its advantages of water selective plugging features (not pluggingoil). In this paper, a novel CO2 foam system was developed for high temperature and high salinity(HTHS)(85 ℃, 60,000 mg/L) aiming at solving the gas channeling in Changqing Oilfield. Taking the foam half-lifeas the evaluation standard, the optimum foam system (0.5 wt% EC-1 + 1 wt% SiO2) for the target reservoirwas determined. The influences of temperature, salinity and pressure on the CO2 foam performance werestudied by high temperature and high pressure(HTHP)method. The ability and mechanism of anti-gaschanneling were studied by experiments of sand packed tube and microscopic displacement,respectively. The results showed that the foam system possessed good foam properties at HTHS withpressure. As the concentration of SiO2 nanoparticles increased, the resistance factor of the foam systemincreased. However, temperature showed an adverse effect on foam stability, the resistance factordecreased with the increase of temperature. The Jamin superposition and emulsion plugging mechanismof foam system was revealed by microscopic displacement experiments.

In polymerflooding process, the poor solubility of polymer and the wrap of incompletely dissolvedpolymer particles with heavy oil lead to the generation of complicated blockage, which seriously affectsthe normal production of wells. Therefore, how to fabricate an effective blockage removal agent isparticularly important. Based on the blockage from Bohai Offshore Oilfield in China, a blockage removalagent composed of (0.5 wt% potassium persulfate + kerosene (the ratio of kerosene: blockage is 3:5)+0.3 wt% OP-10, the oil-water ratio is 1:9) was developed. The removal effect and mechanism werecharacterized by weight loss method and core test. Moreover, the emulsification property of the removalagent was also evaluated by microscopic appearance. The results showed that the blockage removal agentcan be formulated as an O/W emulsion and had good stability for more than 72 h. Core test showed thatthe permeability had a significant improvement after injection of removal agent. The emulsion-typeremoval agent can demulsify after contact with the blockage, then the oil-soluble detergent as internalphase in emulsion can be released which contributes to the wash off of heavy oil. Accompanied with thepolymer degradation by the oxidant, this agent realized the effective dissolution and removal of blockage.

High-frequency pulsed alternating currentfield (HFPACF) has attracted attentions owing to its excellentperformances of eliminating short circuit, saving energy and reducing environmental pollution. To studythe coalescence mechanism of aqueous drops in water-in-oil (W/O) emulsions under HFPACF, micro-behavior of dispersed drops for W/O emulsion was monitored by using a self-designed micro-visualmodel and coalescence mechanism was analyzed by discussing effects of pulse amplitude, pulsefrequency, pulse width ratio, demulsifier concentration, aqueous mass ratio of emulsion, and differentmodel oil emulsions. The results show that the dispersed drops coalesce under the action of electricfield,and the particle size of dispersed drops increases with the increase of pulse frequency and amplitude. When the pulse frequency or amplitude reach to a critical value, aqueous drops are driven to form waterstring or water channel between two electrodes which hinders further drops coalescence in other areas. However, with the increase of pulse width ratio, the size of dispersed drops increases slowly. Theoptimum pulse frequency and pulse amplitude are obtained at 3.9 kV and 4.21 kHz, respectively, theoptimal pulse width range is 54.9%-84.4%. When the concentration of demulsifier is 60 mg/L, thesynergistic demulsification effect achieves the highest performance. When the aqueous mass ratio ofemulsion reaches a high level (over 30%), which means the drops in emulsion have big size, thecoalescence performance under the same electricfield strength is great. Also, it is discovered that thedispersed drops in Yongping model oil emulsion have difficulty in forming water chains, since there aremuch asphaltenes and resins in the water-oil interface leading to high strength offilm. For Shuanghe oilemulsion drops are prevented from coalescing, because it contains a mass of paraffin, which can stabilizeemulsion at low temperature.
