油层爆燃压裂器——油层改造新工具

Reservoir Deflagration Frac Tool—A New Tool for Reservoir Reforming

本文介绍了油层爆燃压裂器,探讨了它的增产原理,说明由它所产生的多条径向裂缝与油层原生裂缝沟通可以使油层增产;通过自行支撑的非填砂裂缝来保持良好的导流能力,以延长增产周期,指出了良好解堵作用产生的原因,文章还介绍了六个井次的油井初步试验情况,表明它是一种很有前途的油层增产和油层解堵新工具。

The reservoir deflagration frac tool is introduced in this paper. The principles for increasing production are discussed, i. e. by creating multiple radial fractures connected with original reservoir cracks to increase production. It can keep good flow capacity by self-propped cracks to prolong the production increasing period. Reasons for relieving the plugging are presented. Preliminary tests with the tool in six wells are also introduced, which show that it is a promising technology for increasing oil output and for reservoir unplugging.
