摘要:

为实现黄桥地区高含CO2气井产出物高效回收及有效利用，采用热力学状态方程（PRSV状态方程、WS混合规则）和闪蒸计算理论对黄桥地区高含CO2气井产出物进行相态计算，明确了黄桥地区高含CO2井流的相图特征和CO2对油气烃类体系相态的影响：含有CO2的油气烃类体系p-T相图的气液两相区面积随CO2摩尔分数的增加而显著缩小。根据产出液的相态特征，制定了单井地面工艺处理流程，分析了该产出液处理工艺中关键设备（旋流分离器、CO2压缩机）的操作参数：当前选取的操作参数均处于旋流分离器的可靠工作区域内（单相气区）；整个CO2压缩机工作压力和温度范围内无液相析出。经验证，制定的黄桥地区现有高含CO2单井集输工艺流程和设备操作工况参数合理，能够实现对该地区高含CO2井流中游离水和液态原油的有效脱除，可在该地区类似条件区块推广使用。
