QHD32-6油田深部液流转向效果影响因素分析

Analysis on Influencing Factors of Application Effect of Deep Fluid Diversion in QHD32-6 Oilfield

为分析深部液流转向在QHD32-6油田的适应性,本文应用关联分析法从地质油藏、生产动态、调堵药剂体系、施工工艺四个方面对现场应用的深部液流转向井进行效果影响因素分析,总结出深部液流转向效果主要影响因素有油藏地质因素井组受益油井厚度、水井渗透率级差;生产动态因素产量(调前产液、累计产液);施工因素爬坡压力等因素是影响深部液流转向效果主要因素,为措施选井提供必要的数据参考和现场实施指导。

In order to analyze the adaptability of deep fluid diversion in QHD32-6 Oilfield, the correlation analysis method was used to analyze the influence factors of application effect of the deep fluid steering wells from four aspects： geological reservoir, production dynamics, chemical control system and construction technology. The main influence factors were summed up, such as well group benefit well thickness, injection wells permeability difference, production performance, slope climbing pressure, which could provide necessary data reference and on-site guidance for selection of measures.
