Abstract The Yanchang tight reservoir in the Changqing has shallow burial depth and low static bottom hole temperature. Conventional cement slurries used in this area produced highly brittle set cements with strengths that are developed very slowly. In large-scale oanod aea aaas so se aa as a e ano oasa en and the production life of the well. To solve these problems, a low temperature high strength tough cement slurry has been formulated sse eaea e s e e ea improving agent DRE-300S, and some other cement slurry additives. This cement slurry, at 55 °C, had 24-hour compressive strength of 35.8 MPa, and 168-hour compressive strength of 50.6 MPa. Compared with conventional cement slurries, the compressive strength of this cement slurry was increased by 33.1%, and the elastic modulus reduced by 14.3%, showing good low temperature toughness.
