苏里格气田大斜度井射孔工艺技术难点分析与应用

Difficulty Analysis and Application of Highly-Deviated Well Perforating Technology in Sulige Gas Field

现有的射孔工艺技术一般只适合直井、定向井射孔,无法满足大斜度井、水平井斜段射孔,为探索提高苏里格气田低渗透气藏单井产量的途径,近年来常规井多层系、水平井多段开发思路大力推广。本文通过对苏东57-09H1井斜井段射孔的应用分析,为苏里格气田大斜度井、水平井斜段开发提供了丰富的施工经验和配套技术。

The existing perforating technology can just be suitable for vertical wells directional wells,unable to meet the high angle deviated wells and horizontal wells.In order to improve the single well production of low permeability gas reservoirs in Sulige gas field,normal well multi-layer systems and horizontal well development ideas have been promoted in recent years.In this paper,application of highly-deviated well perforating technology in Sudong 57-09H1 deviated well was analyzed,which can provide rich construction experiences and supporting technology in development of highly deviated wells and horizontal well in Sulige gas field.
