摘要

在采油过程中,为提高产油量而注入的流体可能会在油藏中找到阻力较小的优先路径或断裂岩石,从而使油藏中的许多区域没有被扫过,从而降低了采油效率,使产水量高于产油量。可以采用一致性控制技术来避免这些问题,然后将注入的流体重新导向之前未到达的区段。针对这一应用评估了预成型颗粒凝胶(PPG),这种凝胶是从前体水凝胶中提取的,以盐水悬浮液的形式注入油藏。在这项研究中,对与聚乙烯亚胺(PEI)交联的部分水解聚丙烯酰胺(PHPA)PPG 的热、流变、形态、稳定性和膨胀特性进行了评估。这项工作的另一项研究是评估基于过硫酸铵和次氯酸钠的凝胶破坏系统,该系统可用于解决 PPG 应用中因障碍物而产生的最终操作问题。结果表明,前体的最佳化学成分包括 1.0% 的部分水解聚丙烯酰胺(PHPA)与 3.0% 的聚乙烯亚胺(PEI)交联。这种组合显示出更高的材料强度和膨胀能力,超过其初始质量的 20 倍。过硫酸铵被证明是一种强大的凝胶破坏剂,可使弹性模量降低多达 97%,同时造成结构破坏,扫描电子显微镜(SEM)证实了这一点。

Synthesis of a preformed hydrogel based on polyacrylamide and related gel-breakers with potential application for conformance control

In oil recovery processes, fluids injected to increase oil production may find preferential paths or fractured rocks that offer less resistance to passage through the reservoir, leaving many areas of the reservoir without being swept and consequently reducing the oil recovery efficiency, increasing water production compared to oil production. Conformance control technique can be applied to avoid these problems and then redirect the injected fluids to the segments that were previously not being reached. The preformed particle gels (PPG) have been evaluated for this application, which were obtained from precursor hydrogels and injected into oil reservoirs in the form of brine suspensions. In this study, an evaluation was conducted on the thermal, rheological, morphological, stability, and swelling properties of partially hydrolyzed polyacrylamide (PHPA) crosslinked with polyethyleneimine (PEI) PPG. Another study of this work was the evaluation of gel-breaker systems based on ammonium persulfate and sodium hypochlorite, which can be used to solve eventual operational problems arising from obstructions in the PPG application. The results indicated that the optimal chemical composition of the precursors consisted of 1.0% partially hydrolyzed polyacrylamide (PHPA) crosslinked with 3.0% polyethyleneimine (PEI). This combination exhibited higher material strength and swelling capacity, exceeding 20 times its initial mass. The ammonium persulphate proved to be a powerful gel-breaker, causing reductions in elastic modulus by as much as 97%, alongside causing structural damage that was confirmed by scanning electron microscopy (SEM).
