摘要
岩心为石油勘探与开发过程中所能取得的最完整、最直接的地层、地质资料,可以通过对岩心的分析与研究,制定出更加合理的油田开发方案、准确计算出油田油气储量、制定合理的油田增产措施。近几年,随着油田地层精细化研究的发展,岩心质量的重要性被越来越重视,如果制定方案所参考的岩心地质资料的岩心结构在取心过程中遭到了人为的破坏,甚至细微的结构变化,都可能导致制定的勘探开发方案失效。通过研究岩心完整率,确定提高岩心完整率的方案与措施,从而为细化研究提供更有力的技术保障。
The core is the most complete and direct stratum and geological data that can be obtained in the process of petroleum exploration and development.Through the analysis and research of the core,it is possible to formulate a more reasonable oilfield development plan and accurately calculate the oil and gas reserves of the oilfield,put forward oilfield production increase measures.In recent years,with the development of fine research on oilfield strata,the importance of core quality has been paid more and more attention.If the core structure whose geological data is used in the formulation of the plan has been artificially destroyed during the coring process,or even minor structural changes,may lead to the failure of the exploration and development plan formulated.In this paper,by studying the core integrity rate,the plan and measures to improve the core integrity rate were determined,so as to provide more powerful technical support for the increasingly refined research.
