摘要

如何有效堵塞多尺度压裂水通道一直是压裂低渗透油藏实现高效水淹的关键。本文开发了一种适用于堵塞多尺度压裂水通道的新型超分子聚合物复合凝胶。超分子聚合物复合凝胶由聚合物(如聚丙烯酰胺)、交联剂(如聚乙烯亚胺)、超分子凝胶因子(如环糊精)和极性调节剂(如乙醇)组成。聚丙烯酰胺、聚乙烯亚胺、环糊精和乙醇的质量分数分别为 0.15%、0.2%、1% 和 0.2%。在初始状态下,复合凝胶体系的粘度小于 20 mPa-s。在微尺度裂缝中具有良好的注入性能,可进入裂缝储层的深部。在 40 °C 时,复合凝胶体系凝胶化后可形成具有双网络结构的凝胶。其中一个网络是由聚丙烯酰胺和聚乙烯亚胺共价作用形成的,另一个网络是由环糊精在乙醇作用下自组装形成的。复合凝胶的综合性能大大提高。复合凝胶的强度大于 5 × 104 mPa-s,在大规模裂缝中具有良好的堵塞强度。该复合凝胶可用作压裂低渗透油田的一致性控制剂。

Development and Performance Evaluation of a New Conformance Control Agent Gel.

How to effectively plug the multi-scale fractured water channeling has always been the key to achieving efficient water flooding of fractured low-permeability oil reservoirs. In this paper, a new type of supramolecular-polymer composite gel is developed, which is suitable for plugging multi-scale fractured water channeling. The supramolecular-polymer composite gel is composed of a polymer (such as polyacrylamide), cross-linking agent (such as polyethyleneimine), supramolecular gel factor (such as cyclodextrin) and polarity regulator (such as ethyl alcohol). The mass fraction of polyacrylamide, polyethyleneimine, cyclodextrin and ethyl alcohol are 0.15%, 0.2%, 1% and 0.2%, respectively. At the initial state, the viscosity of the composite gelant system is less than 20 mPa·s. It has good injection performance in micro-scale fractures and can enter the deep part of a fractured reservoir. At 40 °C, the composite gelant system can form a gel with a double network structure after gelation. One of the networks is formed by the covalent interaction between polyacrylamide and polyethyleneimine, the other network is formed by the self-assembly of cyclodextrins under the action of the ethyl alcohol. The comprehensive performance of the composite gel is greatly improved. The strength of the composite gel is >5 × 104 mPa·s, and it has good plugging strength in large-scale fractures. The composite gel can be used as a conformance control agent for fractured low-permeability oilfields.
