The tests were conducted through both field experiments by using the methods of sand filter tube and the analysis in the lab.

采用砂滤管法和田间试验，结合室内分析，测定了7种有机物料的腐殖化系数、分解量以及土壤有机质矿化率。

According to the sand filling tube model , research the blank off efficiency、enduring erosion ability and profile control efficiency

采用填砂管模型研究了盐沉析体系的封堵效率、耐冲刷性和调剖效率

According to the sand filling tube model , research the blank off efficiency、enduring erosion ability and profile control efficiency; The single core flow experiment purports that: at the conditions of 20meter/D injection velocity and 0.5PV injection amount, the blank off efficiency keep above 40% after flushing 20PV.

采用填砂管模型研究了盐沉析体系的封堵效率、耐冲刷性和调剖效率；单岩心实验结果表明：当诱导剂注入速度为20m/天、注入量为0.5PV时，封堵率为66.67%，地层水冲刷20PV后封堵率保持在40%以上。
