摘　　要：为确定二连油田吉３２断块的开发方式，采用该块具有代表性的油层岩芯及该块２０３井地面原油在单管模型中进行了不同条件下的驱油模拟比较实验，主要结果如下：（１）６０℃、１２０℃、２００℃温度下的水驱，最终采收率分别为４７．０７％、５９．１６％和６９．１５％；（２）２００℃水蒸汽驱，最终采收率为７１．６３％；（３）由最终采收率和累积驱出油量与驱替化学剂量之比确定，较好的化学剂为阴离子表面活性剂ＴＲ９４１，其最经济浓度为１２００ｐｐｍ；（４）１２０℃、２００℃温度下１２００ＴＲ９４１驱的最终采收率分别为６８．３４％和７６．４１％The displacement efficiencies of several oil recovery methods for a viscous heavy crude of Block Ji-32 ,Erlian Oil Fields,are investigated through oil displacing tests on a sandstone reservoir core sample.The ultimate oil recoveries of watar flood at 60℃,120℃ and 200℃ are 47. 0%,59. 07% ,and 69. 15% , that of steam flood at 200℃-71. 63% and that of 1200 ppm anionic surfactant TR941 flood at 120℃ and 200℃ -68. 34% and 76. 41 % of the saturated oil ,respectively. 1200 ppm is the economically optimal surfactant concentration established on the basis of ultimate oil recoveries and ratios of oil recovered to chemical injected.
