Well cementation cement reinforcing agent for heavy oil thermal production well as well as preparation method and application of well cementation cement reinforcing agent
The invention relates to the field of heavy oil recovery, and particularly discloses a heavy oil thermal production well cementation cement reinforcing agent and a preparation method and application thereof, and the heavy oil thermal production well cementation cement reinforcing agent comprises the following components by weight: 75-85 parts of a high temperature stabilizer, 20-30 parts of an early strength agent, and 1-5 parts of a flexibilizer. According to the well cementation cement reinforcing agent for the heavy oil thermal production well, cement paste has good mechanical properties in a medium and low temperature environment, set cement has good compressive strength, and formation fluid packing failure of a well cementation cement sheath under operations of pressure testing, perforation, fracturing and the like can be effectively inhibited; in a high-temperature environment, degradation of mechanical properties such as compressive strength and breaking strength of set cement can be effectively inhibited, and the cement paste has important significance in improving the well cementation quality of a heavy oil thermal production well, prolonging the service life of a heavy oil well and improving the exploitation efficiency of heavy oil resources.
本发明涉及稠油开采领域，具体公开了一种稠油热采井固井水泥增强剂及其制备方法和应用，该稠油热采井固井水泥增强剂包括以下成分及其重量份：高温稳定剂75‑85份，早强剂20‑30份，增韧剂1‑5份。本发明的稠油热采井固井水泥增强剂使水泥浆在中低温环境下有较好的力学性能，水泥石具有较好的抗压强度，能有效地抑制固井水泥环在试压、射孔、压裂等作业下出现的地层流体封隔失效；在高温环境下，能有效地抑制水泥石抗压强度、抗折强度等力学性能衰退，对改善稠油热采井固井质量、延长稠油油井使用寿命、提高稠油资源开采效率具有重要意义。
