喇嘛甸油田葡I 1-2储层精细地质研究及在聚驱开发中的应用
|
摘要
喇嘛甸油田葡Ⅰ1-2储层属于泛滥～分流平原环境下的大型河流相沉积产物，储层模式复杂多变，砂体类型总体上属于巨厚沉积的复合体系，砂体内部非均质性极为严重，呈现多段多韵律的水淹特点。
本文以现代沉积学理论为指导，参考野外地质露头资料，依据喇嘛甸油田密井网测井曲线所能反映出的各种沉积特征和沉积界面，采用模式预测描述方法，由大到小、由粗到细逐级解剖砂体几何形态和内部建筑结构，对该油田葡Ⅰ 1-2储层的沉积模式进行了详细研究与具体论述，建立了相关的地质模型，划分出8种适合油田开发实际需要的储层微相。利用成因模式法，通过合理解剖砂体，预测性地确定出砂体边界，将复合型砂体解剖为单砂体。并通过储层非均质特点分析，形成了储层流动单元划分的静态定量化描述模型。
在此基础上，从砂体的沉积模式和流动单元的连通关系入手，分析了影响聚合物驱油效果的地质因素和不同类型井注聚后动态变化特征，给出了一套砂体沉积的韵律类型、连通状况、微幅度构造及注聚前含油饱和度与聚合物驱增油效果的经验关系，并在确定剩余油分布状况及措施挖潜工作中得到广泛应用，为编制油田聚合物驱油开发方案及注聚后的跟踪调整，提高聚合物驱油效果提供了地质依据。
The P I 1-2 formation of Lamadian oilfield is a large sediment of fluvial facies under the environment of flood and distributary plain, the model of formation is complicated and changeable, the type of sand body is a composite system with huge thickness, the heterogeneity of sand body is very serious , the flooding characteristics of the sand body shows multi-section and rhyme.
This paper is on the guide of modern sedimentary theories, refers to data of geological outcrop on open field, bases on the sedimentary characteristics and interfaces shown by well log data of high density well pattern in Lamadian oilfield, applies the method of model prediction and description, dissections the geometry and structure of the sand body from the large and rough to small and fine gradually. The sedimentary model of P I 1-2 formation of this oilfield is studied in full detail and discussed specifically, the relative geological model is established, and the eight formation tiny facies which meets the need of oilfield development are divided. By Application of the method of causes and effects model and dissection the sand body reasonably, the boundary of sand body is given in prediction, the composite sand body is dissection the single sand body. By analyzing the heterogeneity of formations, the static and quantitative description model which applied to divide the flow unit of formation is established.
Basing on the above study, by the connection of single sand body or flow unit, the dynamic behavior of different well after polymer flooding and the geological factors which affects the effect of polymer flooding are analyzed. The type of rhyme, connection relation, tiny structure and the empirical relation between oil saturation before polymer flooding and the effect of improving the recovery after polymer flooding are given, and applies to determine the remaining oil distribution and analyze the stimulation effect widely. The geological bases of improving the effect of polymer flooding and making project of polymer flooding development and adjustment after polymer flooding are provided.
