摘要:
塔里木盆地顺北地区超深断控缝洞型油气藏目的层埋深大,储层非均质性强,上覆地层岩性复杂,多期断裂破碎带发育,钻完井工程难度大,无现成经验可借鉴,勘探开发面临巨大挑战。通过搭建地质-工程、勘探-开发一体化协同管理平台,将地质研究、工程设计和组织实施纳入一体化协作体系。针对超深断控缝洞型油气藏的地质特点与工程难点,形成“钻井设计(储层建模与井型设计、储量估算与井网构建、井轨迹优化)、钻完井工程(风险预测与优快钻井、分段酸压与衬管完井、储层描述与分类改造)”一体化技术体系,钻井成井周期明显缩短,单井产能明显提升,新发现顺北4号、8号断裂带两个亿吨级规模增储区带,为顺北油气田勘探开发提供重要技术支撑,对国内外超深层油气勘探开发具有借鉴意义。
