摘要:
 超深大位移小尾管井完井射孔面临校深难度大、射孔器直径小、射孔穿深小、正压射孔压实严重等问题。大位移小尾管井TCP射孔技术优化了射孔管柱结构，模拟射孔枪起爆压力分析，保证了射孔管柱安全；针对泵送校深和随钻校深方式，采用预校深方式，提高了射孔准确性，保证了射孔校深作业的成功；优选了超深穿透射孔弹，配合后效体射孔技术，在保证穿透污染带的同时，解除了压实带影响，达到了扩孔扩容的目的。该技术在东海某2井成功进行完井射孔作业，初始原油产量达到96 m3/d，远超预期，为同类型井完井射孔施工提供了有益借鉴。
Abstract:
 Perforating completion of ultradeep wells with large extension and small liners has problems such as difficulty in depth calibration, shallow penetration of perforators with small diameters, and serious compaction of positive pressure perforations. The TCP perforation technology optimizes the structure of the perforating string and simulates the initiating pressure of the perforating gun to ensure the safety of the perforating string. It improves the accurate perforation and successful calibration while pumping or drilling through precalibration. The ultradeep penetrating bullet and postcalibration perforation technology ensure to penetrate the polluted zone and reduce the influence of the compact zone, so the purpose of hole expansion can be achieved. The technology has been successfully used for perforating completion in a No. 2 well drilled in the East China Sea. The initial production of crude oil reached 96 m3/d, and far exceeded the expected. The technology provides a useful reference to perforating completion of similar wells.
