Based on the summary of achievements and technologies of oilfield development for Ecuador reservoirs with low relief structure and strong natural aquifer since 2006, the current situation and challenges are analyzed herein, and then, some expected techniques and solutions for stabilizing oil production are proposed. The suitable technologies for exploration and development of this block include: techniques for identification of low-relief traps and integrated predication for thin reservoirs, fine reservoir description techniques, remaining oil distribution prediction, cluster horizontal wells with large displacement in jungle, techniques for controlling water cut and stabilizing oil rate in ultra-high water cut stage. The current situation and challenges of the block include: due to the low reserve-production ratio and reserve replacement rate, the block has weak reserve basis for stable oil production; the remaining oil in main fields is distributed very complex and scattered, and very difficult to locate; there’s no space for infilling wells in oil areas; the unique pay zone has small remaining thickness, the wells have little potential for stimulation; due to the large liquid production, the capacity of surface equipment cannot meet the requirement for stimulation, therefore, some wells with high water cut have to be shut off to control the water yielding. Aiming at the current situation and challenges mentioned above, this paper presented some expected techniques and solution for stabilizing oil production, including identification of low relief traps, remaining oil distribution prediction, horizontal well techniques, integrated stimulation techniques and optimization of injection-production system.
