%X 被称作“千层饼”的多薄层低渗透油气藏，压裂改造难度很大。为了实现常规油气产能的顺利接替，多薄层储层的有效开发，对大王北油田应用的压裂工艺技术进行了对比分析，优选了多薄层暂堵压裂技术。从暂堵材料优选、技术参数优化等方面进行研究，形成了针对性的暂堵压裂方案，特别是建立了层间暂堵和缝内暂堵堵剂用量计算模型和优化图版，应用于现场，升压明显，增产显著，对比邻井日增产达2倍。表明暂堵压裂对于多薄层储层具有适应性，通过匹配针对性的暂堵压裂方案，可以有效实现增储上产的目的。<br />
It is very difficult to fracture the multi thin layer of low permeability oil and gas reservoir, called “thousand layer cake”. In order to realize the smooth replacement of conventional oil and gas production capacity and the effective development of multi thin layer reservoir, the fracturing technology applied in Dawangbei oilfield is compared and analyzed, then the multi thin layer temporary plugging fracturing technology is optimized. Through the research on the optimization of temporary plugging materials and technical parameters, a targeted temporary plugging fracturing scheme is formed. In particular, the calculation model and optimization chart of the amount of temporary plugging agent between layers and in fractures are established. When applied to the field, the pressure rise is obvious and the production increase is significant. Compared with the adjacent wells, the daily production increase is up to twice. It shows that the temporary plugging fracturing has adaptability for multi thin layer reservoirs. By matching the targeted temporary plugging fracturing scheme, the purpose of increasing reserves and production can be effectively realized.
