摘要:
对于非均质性较强的陆相油田储层,长期注水开发易形成水流优势通道,造成无效水循环,波及系数降低,严重影响开发效果。以扶余X17-19 区块为例,依据岩心和镜下薄片观察结果从地质角度将区内水流优势通道分为渗流型、管流型、缝面型优势通道3 类。三者在空间上交互沟通形成多种组合模式的复杂窜流网络系统,以“水井– 天然裂缝– 高渗带– 压裂缝– 油井” 模式为主。基于岩心、测井及生产动态资料分析了水流优势通道的剖面和平面分布,并以沉积微相与高渗区相结合验证了识别结果的合理性,认为Ⅱ砂组6 小层的X17-019.4 井与X17-19.1 井方向存在水流优势通道。依据水流优势通道类型和强度,采取深部调驱或井网调整措施打破目前的水流网络达到治理的目的。
Abstract:
For reservoirs in land oilfield with strong heterogeneity, long-term waterfloodingcan easily create preferential water flow passage, causing ineffective water circulation, reducing the sweep coefficient, and severely impacting the development effectiveness. Take Fuyu X17-19 Block as an example, based on core and thin slice observation under microscope, the preferential water flow passage within this block is divided into three categories: seepage, pipe flow and seam flow. The three flow passages connect with each other in space and form a complex channeling network system with multiple combination patterns, dominated by ’water well – natural fracture – highly seeping zone – fractures – oil well’. The profile, the plane distribution and the dominant factors of the preferential water flow passage were analyzed based on the data of core, logging and production performance, and the reasonableness of the results were identified based on sedimentary micro-facies and high permeability area, and it was thought that there existed preferential water flow passage in direction of wells X17-019.4 and X17-19.1 in six small layers of No.Ⅱ. sand group. The purpose of treatment by breaking the present water flow network is achieved by deep flooding or well pattern adjustment based on the types and intensity of preferential water flow passage.
