针对裂缝性油气藏勘探开发的热点、重点和难点问题进行了论述。研究认为裂缝形成机理及发育特征识别技术成为广泛研究的热点和低孔、低渗储层评价的关键。同时,储层裂缝发育机制的复杂性决定了裂缝发育特征识别技术的难度,特别是天然裂缝的识别技术的研究仍是当前研究的难点,其对天然裂缝分布特征的认识准确与否,直接关系到对裂缝性储层的评价,影响地质储量的计算和经济评价,甚至关系到一个油气田能否顺利投入开发。
This paper discusses the hot spots, key points and difficult points of the exploration and development of fractured reservoirs. It is considered that the mechanism of fracture formation and the identification of developmental features have become the hotspots of extensive research and the key to the evaluation of low-porosity and low-permeability reservoirs. At the same time, the complexity of reservoir fracture development mechanism determines the difficulty of fault development feature recognition technology. Especially, the study of natural fracture recognition technology is still the difficult point of current research. The accurate understanding of natural fracture distribution features is directly related to To the evaluation of fractured reservoirs, affecting the calculation of geological reserves and economic evaluation, and even related to an oil and gas fields can be successfully put into development.
