摘　　要：中国石化川西气田是继普光、元坝气田后又一个大型海相酸性气田。川西气田雷口坡组四段三亚段(T2l4-3)储层段具有储层单层厚度薄、埋藏深度大、气藏含硫高、气水关系复杂的特点,水平井轨迹控制优化技术对该类气藏的效益开发意义重大。通过实时跟踪分析,总结出控标志层、控入靶角度、控水平轨迹及优化靶框、优化靶点、优化压裂分段的“三控”、“三优”的水平井轨迹控制优化技术。此项技术在钻井实施过程中现场应用效果好,实现了长穿优质储层和有效酸压改造,极大提高了优质储层钻遇率。Western Sichuan gasfield of SINOPEC is another large marine acidic gasfield after Puguang and Yuanba gasfield.The 3rd sub-member reservoir of Leikoupo 4th member(T2l4-3)is thin single layer thickness burial depth,high sulfur content and have a complex gas-water relationship.The horizontal well trajectory optimization technology is of great significance to the efficient development of this kind of gas reservoir.Through the real-time tracking analysis,summed up the"three control"and"three optimization"as a well trajectory control and optimization technology,which is control the marker bed,control the drill angle into target and horizontal trajectory,optimize the target frame,optimize the targets position and optimize the fracturing section.The application of this technology has achieved good field application effect in the drilling implementation,realizing the long penetration and effective acid pressure transformation of high-quality reservoir,and greatly improving the drilling rate of high-quality reservoir.
