摘要

摘要: YD油田钻井中存在地质环境复杂、多套压力体系并存及高压沥青层溢漏同存等问题,给钻井施工和井身结构优化设计带来困难.在实钻资料分析、确定必封点及重新认识Gachsaran地层孔隙压力的基础上,采用自下而上的设计方法,先后形成了适合YD油田复杂地层钻进的3套井身结构.针对部分Gachsaran盐水地层存在异常高压层的情况,从安全钻进角度考虑,设计了高压盐水层井身结构;对于正常压力Gachsaran盐水层,为提高机械钻速和降低钻井成本,形成了简化高效的常规井身结构;对于Kazhdumi高压沥青层,从安全钻井实现地质目的考虑,形成了延长 244.5 mm技术套管和专打专封2种井身结构.优化后的井身结构在YD油田20余口开发井中进行了应用,取得了良好的应用效果.YD油田井身结构的优化,不仅为该油田"二期工程"奠定了基础,也对国内外同类型的碳酸盐岩油藏开发具有借鉴意义.

Abstract: In the YD Oilfield, the complex geologic environment, coexistence of multiple pressure systems and high pressure asphalt formation that easy overflow or lost circulation have been the challenge to drilling and optimization of casing program. By analyzing drilling data, determing the setting depth of casing, reviewing pore pressure of Gachsaran Formation, together with the bottom-up designing method, three exclusive casing programs for drilling complex formations in the YD Oilfield were determined.Due to abnormal high pressure existed in parts of Gachsaran salt water formation, a special casing program was developed for dealing with it. But for the normal-pressure Gachsaran Formation, a simplified and efficient casing program was also developed to improve ROP and lower the drilling cost.As for the high-pressure Kazhdumi asphalt formation, two casing programs were developed with prolonged 244.5 mm intermediate casing for special drilling and isolating Kazhdumi Formation. The optimized casing programs were satisfactorily applied in more than 20 development wells in the YD Oilfield. The casing program for high-pressure salt water formation achieved safe drilling in some Gachsaran Formation. The conventional casing program highly enhanced the ROP and shortened the drilling cycle. The casing programs for the asphalt formation fully ensured the drilling safety in high-pressure asphalt formation. These optimized casing programs have laid a good foundation for Phase Ⅱ development of the YD Oilfield, and will provide the reference for similar carbonate reservoir development at home and abroad.
