新型耐温防膨剂的合成与性能研究

Research on the Synthesis and Properties of A Novel Temperature Tolerance Clay-Antisweller.

针对辽河油田庙五块８２ － ４０ 井组注蒸汽驱油特点，研制了一种新型耐温防膨剂 Ｍ Ｃ－ １ ，考察了 Ｍ Ｃ－ １ 的加量对地层渗透率、防膨效果、驱油效果及长效性的影响，得到了耐高温防膨液组成与配方，并对其作用机理进行了初步分析。

According to characters of steam flood for Miaowukuai 82-40 well series in Liaohe oilfield, a new anti-sweller MC-1 with hightemperature tolerance has been prepared. Influence of MC-1 concentration on permeability of formation, anti-swellering effect, oil displacement efficiency and effective time as well are investigated. The results show not only that working concentration of MC-1 is very low, but it has hightemperature tolerance,little damage on strata and excellent long-trem function.
