A26水平井完井产能影响因素分析

QHD32－6油田A26水平井的设计水平段长度达1100m，实际水平长度为842．9m，储层岩石胶结疏松，孔隙度大，渗透率高，根据现场观察法，经验法及力学计算法等防砂判据综合判断，油井出砂将成为贯穿开发生产过程的主要问题，防涛则为开发生产及油层保护的重点和核心，A26水平井采用烧丝筛管完井防砂，针对QHD32－6油田A26水平井的具体参数，分析了影响天然产能的几个因素，还分析了影响绕丝筛管完井产能的几个因素，对指导该井的投产设计具有重要的意义。

Analysis on the Parameters Affecting Well Completion Productivity of A26 Horizontal Well

The designed well length of A26 horizontal well is up to 1100 meters, and the actual length of the well is up to 842.9 meters. The oil field is with high porosity and high permeability and unconsolidated payzones. According to the sand control criteria of on-site observation,experience,and mechanics calculation et al,the sand production will be the main problem of oil exploitation,and the sand control will be the key points of oil development and formation damage control. So, the A26 horizontal well will be completed with wire-wrapped screen. According to the practical parameters of A26 horizontal well in QHD32-6 oil field, several parameters affecting the natural productivity and wire-wrapped screen well completion productivity have been analyzed, that is very important to guide the commissioning design of the well.
