C油田为吉林油田新发现的浅层稠油油田,由于埋藏浅而引起油层低温、低压,油层条件下原油流动性差,开采过程中储层易受析蜡冷伤害,造成常规开采产能低,甚至无产能,严重影响了油田的正常生产,制约了该区储量的有效动用。针对这一现状,对该油田重点开展了原油析蜡实验、热采物理模拟实验、热采数值模拟研究,从理论上明确了提高地层温度、保持地层压力、预防原油析蜡是实现C油田有效开发的关键。结合现场蒸汽吞吐、蒸汽驱、火烧油层等多种热采试验的开发效果,明确了主体资源可采用热水驱开发,局部低温、高含蜡区可采用火烧油层的开发方式。

C oil field is shallow heavy oil reservoir discovered recently in Jilin Oilfield.Due to the shallow burial depth,the reservoir temperature and pressure are low,the crude oil fluidity is poor,and the reservoir suffers easily wax precipitation code damage during the production process,which makes the low deliverability,even no deliverability.That seriously affects the normal production of oilfield and restricts the effective development of reserves in the area.In view of this situation,crude oil wax precipitation experiment,physical simulation experiment and numerical simulation of thermal recovery are carried out.It is defined that the key for effective development is to increase the formation temperature,to maintain reservoir pressure and to prevent crude oil wax precipitation.Combined with the development effectiveness of the steam stimulation,steam flood and fire flood,it is defined that hot water drive can be used to most resources and fire flood can be used in local district with low temperature and high wax content.
