摘要
随着石油工业的不断发展,大斜度井、分支井和水平井等钻井技术被用于开发规模更小、油层更薄、物性更差、非均质性强的油藏,由于随钻测井（LWD）自身的特点,使其更多地被用于这些油藏的评价和地质导向钻井工作中.在介绍随钻测井技术特点、总结随钻测井解释在地层评价、地质导向方面应用效果的基础上,论述了如何利用井下实际地质特征确定、控制井眼轨迹与油藏空间关系,分析了随钻测井解释评价技术目前存在的难点问题,提出了今后研究方向.
With the continuous development of oil industry, high angle deviated holes, multi-branch wells and horizontal wells etc. have been used to smaller sized oil reservoirs, thinner reservoirs, reservoirs with poorer physical properties and serious anisotropic reservoirs, etc. Due to the characteristics of LWD, it is applied to the evaluation of these reservoirs and geosteering drilling. In this paper, the technical characteristics of LWD are introduced, and the application resuhs of LWD interpretation for formation evaluation and geosteering are generalized. Based on the above research, the technique of how to determine and control the relationship between the well track and oil reservoir position according to the actual geologic features is discussed. In this paper, the difficulties for LWD interpretation evaluation technique are analyzed also.
