摘要
高升油田高3618块属于典型中深厚层块状稠油纯油藏,已进入蒸汽吞吐开发末期,开发效果差。在开展火烧油层适应性研究基础上,选择主体部位6个井组开展火烧油层开发试验。目前试验井组火井全部点火成功并处于高温氧化燃烧状态,地下火线逐步推进,油藏温度场逐步建立,一线对应生产油井全部受效,井组日产油较驱前上升20t/d,主要技术指标达到方案设计要求,为下步扩大实施规模及其他同类型油藏实施火烧油层开发提供了技术储备。
Gao 3618 block of Gaosheng oilfield is a typical mid-deep,thick,massive,pure heavy oil reservoir,which has entered the late life of cyclic steam stimulation and shown poor development effect.Six well arrays in the main part of the reservoir have been selected to conduct a pilot test of in situ combustion on the basis of adaptability study.All the ignition wells in the pilot area have been successfully ignited and are currently in the state of high-temperature oxidation and combustion.The combustion front is advancing gradually,reservoir temperature field is being built,all the corresponding producers have shown responses,the daily oil production of these wells has increased 20 t/d comparing with that before ISC,and the main technical indicators have met design requirements.This study has provided technical reference for further expanding operation scale and implementing ISC in other similar reservoirs.
