子长油矿4207裸眼井“压胀松动”增产技术现场试验

Field Test of “Loosening Rock by the Dilatancy of Explosive Waves” in the Open Hole Well 4207 in Zichang Oil Field

为了研究“压胀松动”增产技术的增产效果和施工工艺，在延长石油管理局子长油矿对４２０７裸眼井进行了现场试验．介绍了裸眼井“压胀松动”增产技术的基本原理、该井现场试验所需岩石力学参数的测定、药量的计算及装药设计．并对施工工艺和实验结果进行了分析和研究，说明“压胀松动”增产技术对此井是有效的．

Loosening rock by the dilatancy of explosive waves is a stimulation treatment, and it is being in testing stage in our country. Rock is loosened under the dilatant condition formed by the superposition of explosive waves, the formation permeability near wellbore zone is increased,so oil production can be increased.The test is made for knowing the result of the well stimulation and operating sequence. It is successful in technology, and the oil production of the well is 4 times as much as that of it before the treatment. In the paper, the determination of rock's mechanical parameters, the calculation of explosive load, and explosive design are discussed.
