| 英文摘要 | The mechanical property of cement sheaths is a primary indicator for evaluating the quality of well cementing in oil and gas wells. With the exploration and development of complex reservoirs, higher demands are placed on the mechanical properties and the dynamic constitutive models of oil well cement (OWC). This study modified the strength model based on the original Holmquist-Johnson-Cook (HJC) constitutive model and established a dynamic constitutive model suitable for composite toughened OWC with added styrene-butadiene rubber (SBR) latex and polymer polypropylene fiber (PPF). Mechanical tests were conducted on basic and toughened OWC to determine the model parameters, including uniaxial compression, triaxial compression, brazilian splitting, and split hopkinson pressure bar (SHPB) tests. Then, the parameters of the HJC model were calibrated through numerical simulation. Finally, liquid carbon dioxide phase change blasting (LCPCB) experiments were performed to compare the failure characteristics of the two types of OWC at high strain rates, and numerical simulations were used to verify the effectiveness and accuracy of the improved HJC model parameters. The numerical simulation results of the LCPCB test indicate that the fracture patterns and fracturing effect evaluation coefficient of toughened OWC agree with the experimental results. The improved HJC model can effectively describe the dynamic mechanical behavior of toughened OWC during impact processes and provide valuable parameter references for constitutive models of OWC and theoretical support for optimizing designs of perforation completion and fracturing operations after well cementing. |
