摘　　要：水力压裂过程中往往会产生复杂裂缝,为了避免或减轻复杂裂缝的不利影响,需进行系统的优化设计。考虑地层条件、完井方式等因素对产生复杂裂缝的影响,研究和优化压裂液性能及施工参数,提出有效的封堵和降滤措施以防治或削减复杂裂缝。The occurrence of complex fractures is unavoidable sometimes during hydraulic fracturing,and how to avoid or minish the adverse effects of complex fractures is a comprehensive system engineering,so we should systematic optimize the fracturing design.we consider the main causing the complex fractures factors to systematic study and optimize the fracturing fluid performance and construction parameters,and to put forward an effective blocking complex fractures and reduce filtration measures when complex fractures occur.Eventually we form the fracturing optimization design techniques.Applications show that this technology is effective for preventing and reducing complex fractures during hydraulic fracturing.
