濮67块沙三中6-10低渗透油藏层序地层研究

Study on Sequence Stratigraphy of Pu 67 Block S_(3m)^(6-10) The Low Permeability Oil Reservoir

应用高分辨率层序地层学,依据基准面变化中的过程-沉积响应,分析沉积过程中沉积物体积分配及其相伴生的相分异,进行等时地层对比。在岩心基准面旋回识别的基础上,对应测井资料分析,细分地层,建立濮67块沙三中6-10低渗透油藏地层格架,为分采、分注、寻找剩余油提供地质依据。

In order to deepen geological recognition , realizing production increasing ,the low permeability reservoir is going to be as main study object, a new framework of Pu 67 block S3m6-10 low permeability reservoir was established based or) the detailed eorreetion under the law of high resolution sequence stratigraphy principles, in which the volumetric partition and facies differentiation in the sedimentary process were analyzed carefully. In the core, hierarchy of base level cycles were recognized. Through the correction of logs, We subdivided stratigraphy and founded the detailed reservoir slratigraphie framework. it provides a geologic basis for separating stratum water flooding, separating zone production and searching residual oil.
