摘　　要：多孔隙金属筛管主体挡砂层采用抗高温、耐腐蚀性能优良的金属研制而成,因其特殊的三维立体孔隙结构,筛管具有较强的通透性和过流能力,目前在常规冷采开发油气田适用性良好。为进一步评价筛管在稠油热采条件下的适应性,开展了多轮次蒸汽吞吐防砂模拟试验,模拟筛管在经过多轮次蒸汽吞吐过程中的防砂效果变化情况,分析在多轮次注采过程中筛管内外的压力、温度、出砂量和出砂粒径的变化规律。试验结果表明,经过16个轮次的高温蒸汽吞吐(蒸汽温度350℃、注入压力17 MPa)试验,筛管出砂质量分数在1.86×10^(-7)%~6.63×10^(-6)%之间,出砂粒径中值略小于筛管挡砂精度,渗透率保持能力在85.7%左右,筛管整体过流能力和抗堵塞性能保持率良好。试验结果充分证明了筛管在稠油热采油藏开发方面具有良好的防砂效果和过流性能,可为稠油热采工况下油气田防砂完井提供技术参考。The main sand-control layer of the porous metal screen is made of metal with excellent high temperature resistance and corrosion resistance.Due to its special three-dimensional pore structure,the screen has strong permeability and flow capacity.It has good applicability in conventional cold production and development in oil and gas fields.In order to further evaluate the adaptability of the screen under the conditions of heavy oil thermal development,multi-round of steam huff and puff simulation experiments were carried out to simulate the change of sand control effect of the screen in the process of multi-round of steam huff and puff stimulation,and analyze the pressure,temperature,sand production and sand particle size of the screen during the injection and production process.The experimental results show that after 16 rounds of steam huff and puff experiments(the maximum steam temperature is 350℃,and the maximum injection pressure is 17 MPa),the sand concentration of the screen ranges from 1.86×10-7%to 6.63×10-6%,the median particle size of the sand is slightly smaller than the sand control accuracy of the screen,and the permeability retention capacity is about 85.7%.The overall flow capacity and anti-plugging performance retention rate of the screen is good.The experimental conclusion fully proves that the screen has an excellent adaptability in the development of heavy oil thermal recovery reservoirs.
