摘　　要：在油田酸化作业中,由于地层孔隙或裂缝的问题,使注入的酸液大部分只能波及到整个产层渗透率较高的区域内,波及系数小,影响了酸化效果,为此开发了XN—1暂堵剂。经过对油溶性暂堵剂XN—1的主要物理化学性能的评价及暂堵、解堵效率的考察,证明了XN—1暂堵剂具有良好的油溶性、水不溶、酸不溶性,且与酸液添加剂的相容性好,可应用于裂缝性油田酸化暂堵作业。Oil soluble temporary plugging agent XN - 1 was synthesized, to overcome the poor efficiency of normal acidizing operation. Laboratory tests indicate XN -1 possesses good oil solubility and temporary plugging property, and compatibility with other normal acid additives. Dis-persants should be added in clay acid to make XN- 1 in good dispersion status.
