油管传输多级起爆负压射孔技术

Tubing Survey Mutal Charge Ignite under Balance Perforating Technique.

为解决同时射开大跨度、多储集层的油气井射孔施工难题 ,开发了多级起爆油管传输负压射孔技术 ,用油管取代夹层枪 ,将原来的一个枪串分成几组枪串 ,每个枪串都装有独立的起爆器 ,起爆方式分为投棒—压力复合起爆、压力—压力复合起爆、分级投棒起爆、投棒压力增压起爆。该技术在华北油田不同井况的生产井、勘探井中应用 15井次 ,一次成功率 10 0 % 。

In this paper,to solve the wide span perforating and many constructer problems in multiple reservoirs,the TCP perforating technique is developed.Instead of using interlayer gun,it uses cubing and changes a cluster of guns into several groups.Each group has his own ignite implement.The ignite models are divided into throw pressure ignite implement,pressure pressure confound ignite,classification ignite.This technique had been used in 15 wells including production wells and survey wells in Huabei oil field,it had achieved great economic profits.
