摘要： 在低渗透油田的生产开发中，压裂的完井工艺是提高油田单井产能的有效增产手段。由于高压注水、持续性注水造成的油田内部原生及压裂次生的裂缝不规律地开启、闭合，致使油井方向形成快速水淹，会对油田产量产生影响。试井通过油水井的单井工况短时调整造成的单井压力、产量变化得出油水井间的连通关系。总结了低渗透油田注水动态裂缝的成因，采用试井方式定量评价油水井间连通关系，通过优化注水井不稳定注水工作制度，控制油水井间裂缝连通，提高注水波及体积，改善注水开发效果。

Abstract: Fracturing completion technology is an effective method of increasing the production of oil wells in the production and development of low-permeability oil fields. Due to the irregular opening and closing of fractures caused by high-pressure or continuous water injection in the oil field， water flooding usually occurs in the direction of the oil wells， which affects the production of the oil field. Well testing method achieves the connectivity between oil and water wells by short-term adjustments in well production condition which results in well pressure and production change. This article summarizes the causes of dynamic fractures in low-permeability oil fields during water injection. Quantitatively evaluate the connectivity between oil and water wells by using well testing methods. Control the connectivity of fracture between oil and water wells and improving the effect of water injection by optimizing the unstable water injection.

Key words: low-permeability oil field, fracture identification, well test, water injection improvement
