方法通过热学和声学方法,论述了岩石热开裂作用的机理,并将此机理拓展到油气田开发应用方面。目的寻找一种既能增加裂缝长度,又能增加裂缝密度的新方法,从而提高原油最终采收率。结果岩石热开裂用于石油开采,能够提高储集层渗透率且不使其非均质性增大;但如何在井筒中对选定层段进行热开裂作业,以及如何运用声学或其它方法对热开裂作用的效果进行检测等都是热开裂应用研究中应加以关注和考虑的问题。结论岩石热开裂在石油开发和核废料储存等领域中,具有广阔的应用前景;然而从目前看,该项研究尚属起步阶段,能否将该项研究成功地应用于石油开采中,还有待于进一步研究
Methods By means of thermal and acoustic methods, the mechanism of thermal cracking in rocks is discussed, and the mechanism is extended to the development and application of oil and gas fields. Aim To find a new method that can increase the crack length and increase the crack density, so as to improve the final recovery rate of crude oil. Results Thermal cracking of rocks for oil recovery increases reservoir permeability without increasing its heterogeneity; however, how to conduct thermal cracking of selected intervals in wellbores and how to use acoustic or other methods The effect of thermal cracking test are all the problems that should be paid attention to in thermal cracking research. Conclusions Thermal cracking of rock has broad application prospects in the fields of oil exploration and nuclear waste storage. However, for the moment, the study is still in its infancy. Whether this research can be successfully applied to oil exploration remains to be seen For further study
