低渗透油藏通常具有低丰度、低压、低产的“三低”特点,其有效开发难度很大。低渗储层中油气富集区,特别是裂缝发育带和相对高产区带的识别评价、开发方案优化、钻采工艺、储层改造、油井产量、开采成本、已开发油田的综合调整等技术经济问题,制约着低渗油藏的有效和高效开发。
Low-permeability reservoirs usually have the characteristics of low abundance, low pressure and low yield, and their effective development is very difficult. Identification and evaluation of hydrocarbon enrichment zones, especially fractured development zones and relatively high-yield zones in low-permeability reservoirs, technologies such as optimization of development plans, drilling and production processes, reservoir alteration, well production, mining costs and comprehensive adjustment of developed oilfields Economic problems restrict the effective and efficient development of low-permeability reservoirs.
