摘　　要：传统的压裂工艺在裂缝控制方面易造成裂缝无法有效控制和导流能力差等问题,从而影响油气产量,投球暂堵技术通过在压裂过程中分阶段封堵部分裂缝口,优化裂缝的延展性和分布,使得主裂缝和次级裂缝均能充分扩展,从而更有效地增大油气藏的渗流面积,提高油气采收率。通过对投球暂堵压裂技术的关键工艺进行分析,开展投球暂堵压裂炮眼封堵技术研究,为推动油气田开发领域的进一步发展奠定基础。Traditional fracturing techniques are prone to ineffective crack control and poor flow conductivity,which can affect oil and gas production.The ball throwing temporary plugging technology optimizes the extension and distribution of cracks by blocking some crack openings in stages during the fracturing process,allowing both primary and secondary cracks to fully expand,thereby effectively increasing the seepage area of oil and gas reservoirs and improving oil and gas recovery.The main purpose of this study is to analyze the key processes of ball throwing temporary plugging and fracturing technology.Based on this,research on ball throwing temporary plugging and fracturing borehole plugging technology will be conducted to lay the foundation for further development in the field of oil and gas field development.
