摘　　要：LL区块油砂埋深浅,黏度特别大,地层中呈现固态,由于油砂的这些特殊性,因此需要一种有效的开采方式,有效降低原油黏度。夹层和贼层分布广,对生产影响大,利用生产指标有效评价其对生产的影响并及时提出应对策略对高效开发油砂具有重要意义。The oil sands in LL block are shallowly buried depth,high viscosity and solid in the formation.Due to these special characteristics of oil sands,an effective mining method is needed to effectively reduce the viscosity of crude oil.Interbeds and lean zones are widely distributed and have a great impact on production.They are great significance for efficient development of oil sands to evaluate the impact of iterbeds and lean zones on production by using production indicators and put forward timely countermeasures.
