102枪装127弹射孔工艺在大庆油田的开发与应用

为探索在大庆油田140mm套管井上应用127射孔弹以提高射孔穿深，达到更好的射孔效果，研制出102枪装127弹射孔工艺技术。模拟井和地面试验井试验表明，该工艺解决了枪身强度、合理装药量等关键技术，使该项新工艺既实现了射孔弹最佳合理炸高和枪靶间隙以达到深穿透的目的，又防止了102枪涨大、炸裂。大庆油田近千口井现场试验表明，该技术的射孔穿深、孔径等技术指标在行业标准允许的范围内，并能有效地提高采液、采油强度。

The Development and Application of Perforating Gun 102 Assembling Perforating Charge 127 Technology in Daqing Oil Field

To increase the penetration of 127 perforating cartridge in 140mm cased wells of Daqing Oil field, and obtain better perforating results, after investigation and theoretical research, the technology of 102 mm perforating gun carrying 127mm perforating charge is presented. The technology is applied firstly in the simulating well and experimented well in the surface and solves the key technical problems, such as gun strength and appropriate explosive load, etc, realizing the optimum clearance of perforating charge, the optimum space between gun and target, and also effectively preventing 102mm perforating gun's inflation and burst. The technology has been used in Daqing oil field for nearly 1 000 wells and its penetration, hole diameter, and other technical index are within the allowed limit of the industrial standard. The technology effectively increases the fluid production rate and oil production rate, having wide application prospect.
