摘要: 为满足塔河油田托甫台区块缝洞型油藏造长缝、深穿透酸压工艺需求，针对该区块奥陶系地层的高温特点，研制了耐温抗盐酸液稠化剂TP-17。以丙烯酰胺（AM）为主，耐温、抗盐2-甲基-2-丙烯酰胺基丙磺酸（AMPS）、自制阳离子单体（X）和马来酸酐（MA）为辅进行四元聚合反应，合成了AM/AMPS/X/MA四元共聚物TP-17。研究发现，最佳聚合反应条件为：AM、AMPS和X等3种单体的物质的量之比为5：3：2，这3种单体的总质量分数为30.0%，MA的质量分数为15.0%，引发剂的质量分数为0.4%，反应温度为80℃，螯合剂EDTA的质量浓度为200 mg/L，反应时间为9 h，反应体系的pH值为7。室内研究及现场试验均表明，TP-17是一种耐温、抗盐、抗剪切、酸溶解及配伍性能优良的酸液稠化剂，在塔河油田托甫台区块深层碳酸盐岩油藏酸压改造中获得较好的试验效果。研究认为，TP-17适用于高温缝洞型碳酸盐岩油藏的深部酸压，具有很好的应用前景。Abstract: In order to meet the technical requirements of acid fracturing with long fractures and deep penetration in the Tuoputai Block of the Tahe Oilfield,a high temperature resistant and salt tolerant acid thickener TP-17 was developed to accommodate the high temperature geologic characteristics of Ordovician Formation.With crylamide (AM) as the principle component,the high temperature resistant and salt tolerant monomer 2-methyl-2-acrylamido-sulfonic acid (AMPS) and self-made cationic monomer (X) and maleic anhydrides (MA) as auxiliary components,the quadripolymer TP-17 formed by polymerization.Research results showed that optimal conditions of polymerization was in terms of molar ratios of 5:3:2,i.e.three monomers AM,AMPS and X,which have total mass fraction of 30.0%,with MA mass fraction of 15.0% and initiator mass fraction of 0.4%.The reaction temperature was at 80℃,with concentration of the chelating agent EDTA was 200 mg/L,the reaction time lasted for nine hours,the pH of reaction system was 7.Lab and field test results indicated that TP-17 was an acid thicker with outstanding heat-resistant,salt-resistant,anti-shearing,acid dissolution and compatibility performances.Desirable effects have been observed in acid-fracturing operations of deep carbonate reservoirs.It is considered that the TP-17 is suitable for acid fracturing in fracture-vuggy deep reservoir,with bright prospects of applications.
