【摘要】 本文在选定的温度、压差、速梯条件下,采用正交法,对SK系列处理剂复配的泥浆,用高温高压动失水仪进行试验,测定损害前后的渗透率值,探讨温度、压差、速梯三个因素对岩心、滤纸上的动滤失速率和岩心渗透率恢复值的影响,还评价了SK系列及CMC处理剂对岩心渗透率的损害程度,并以SK系列与现场常用处理剂的酸溶性进行了比较。更多还原

【Abstract】 Under the selected temperature, pressure drop and speed gradient as well as using the optimized intersect method, the re-prepared mud with SK-series conditioner was tested using the dynamic filtration apparatus at high temperature and high pressure, and the permeability before and after the damage was measured. The effect of three elements(temperature, pressure drop and speed gradient)on the core,dynamic filtration rate at the filter paper and restored value of core permeability was discussed. Meanwhile, the assessment of SK-series and CMC conditioners against the degree of damage of core permeability was made, and the acid solubility of SK-series conditioner was compared with the conditioner currently used in the field.更多还原
