岩石热开裂研究现状及其应用前景

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

Status and prospective application of study on rock thermal fracturing

Method Mechanism of rock thermal fracturing is discussed through thermal and acoustic methods and applied to develop hydrocarbon reservoirs. Purpose To find a novel method, which can increase fracture length and density as well, so as to improve ultimate recovery. Result In developing crude, rock thermal fracturing will increase reservoir permeability but not affect its heterogeneity. However, how to carry out thermal fracturing operation on selected section and how to evaluate its effect utilizing acoustic or other methods are still concerns. Conclusion Rock thermal fracturing has great application prospect in developing hydrocarbon and storing nuclear wastes and the etc, but further study is still necessary to determine whether this study could be possibly applied in crude production judging from current situation.;
