          摘要:
          應用聲波各向異性評價儲層壓裂效果的傳統方法存在很多局限性,為了滿足儲層壓裂效果評價的需求,引入了縱波走時層析成像技術。受鉆井、工程壓裂等影響,井壁附近的地層彈性波速度與遠離井壁處的原狀地層的速度相比有較大的變化,應用縱波走時可以對井壁附近的徑向速度變化進行層析成像,獲取井壁附近地層的徑向速度剖面,用來確定鉆井及工程壓裂在地層中造成的破損范圍的大小進而預測巖石脆性以及評價壓裂效果。速度剖面在評價壓裂效果方面與傳統的各向異性方法對比體現了獨有優勢,當傳統的各向異性方法評價壓裂效果失效時,應用速度剖面可以很好地評價儲層的壓裂效果; 壓裂效果的好壞與壓前的脆性指示有較好的一致性。
          Abstract:
          Abstract: The traditional methods for evaluating the reservoir fracturing performance using acoustic anisotropy have many limitations. In order to meet the requirements of evaluation of reservoir fracture performance, compressional wave travel time tomography is introduced. Affected by drilling and fracturing, the elastic wave velocity near the wellbore has a large change compared with the velocity of the undisturbed formation far from the wellbore. The compressional wave travel can be used to conduct tomography of the radial velocity changes near the wellbore, so as to obtain the radial velocity profile of the formation near the wellbore. The radial velocity profile is then used to determine the extent of damage caused by drilling and fracturing in the formation and to predict rock brittleness and evaluate the fracturing performance. The velocity profile has a unique advantage in evaluating fracturing performance when compared with the traditional anisotropic method. When the traditional anisotropic method fails, the velocity profile can be applied toevaluate the fracturing performance of the reservoir. The fracturing performance is in good consistency with the brittleness indication before fracturing.
