针对油田常用的聚合物交联弹性颗粒堵剂易剪切、耐温性差、对大孔隙封堵强度弱的问题，引入具有一定刚性和网络结构的颗粒，与聚合物单体交联，可提高结构稳定性、耐温性和封堵效果，且制备方法简单、成本低。以分步法制备了互穿聚合物网络（IPN）凝胶。优化了IPN的合成条件。用扫描电镜分析了IPN凝胶的微观形态，并对IPN的粘弹性、耐温性和封堵性能进行了评价。最佳聚合条件为：温度60 °C，单体浓度10.0- 15.0%，交联剂浓度1.0-2.0%，第一网络浓度20%。IPN具有良好的熔融度，无相分离，这是形成高强度IPN的先决条件，而颗粒聚集体降低了强度。IPN具有较好的交联强度和结构稳定性，弹性模量提高20-70%，耐温性提高25%。结果表明，该堵剂具有较好的封堵能力和抗冲刷能力，封堵率达98.9%.冲蚀后的封堵压力稳定性是常规PAM凝胶堵剂的3.8倍。IPN堵剂提高了堵剂的结构稳定性、耐温性和封堵效果。为提高油田堵剂的性能提供了一种新的方法。
In view of the problems of polymer cross-linked elastic particle plugging agents commonly used in oilfields, including easy shear, poor temperature resistance, and weak plugging strength for large pores, the introduction of particles with certain rigidity and network structure, and cross-linking with a polymer monomer can improve the structural stability, temperature resistance, and plugging effect, and the preparation method is simple and low-cost. An interpenetrating polymer network (IPN) gel was prepared in a stepwise manner. The conditions of IPN synthesis were optimized. The IPN gel micromorphology was analyzed by SEM and the viscoelasticity, temperature resistance, and plugging performance were also evaluated. The optimal polymerization conditions included a temperature of 60 °C, a monomer concentration of 10.0–15.0%, a cross-linker concentration of 1.0–2.0% of monomer content, and a first network concentration of 20%. The IPN showed good fusion degree with no phase separation, which was the prerequisite for the formation of high-strength IPN, whereas particle aggregates reduced the strength. The IPN had better cross-linking strength and structural stability, with a 20–70% increase in the elastic modulus and a 25% increase in temperature resistance. It showed better plugging ability and erosion resistance, with the plugging rate reaching 98.9%. The stability of the plugging pressure after erosion was 3.8 times that of a conventional PAM-gel plugging agent. The IPN plugging agent improved the structural stability, temperature resistance, and plugging effect of the plugging agent. This paper provides a new method for improving the performance of a plugging agent in an oilfield.
