74块具有油层厚度大、埋藏深、特低渗透等特点,属于低渗、低孔隙度、高含蜡、高凝固点的难动用油藏,油层为高温、高压异常。针对该块的开采特征和剩余油分布特点,本文根据地质及其开采特征研究了该块实施的加密井网、压裂等各项措施的开发效果。
74 has the characteristics of large reservoir thickness, deep burial and ultra-low permeability, and is a difficult reservoir with low permeability, low porosity, high wax content and high freezing point. The oil layer is characterized by high temperature and high pressure. According to the characteristics of the block mining and the remaining oil distribution, this paper studies the development of various measures such as well patterning and fracturing according to the geological and mining characteristics.
