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。The targeted ultra-deep fault-controlled fractured-vuggy oil and gas reservoirs in the Shunbei area,Tarim Basin is highly heterogenous with great burial depth and lithological complex overlying strata as well as multi-phase faulted fracture zones,all posing drilling and completion challenges with no ready-made experience to draw on.To deal with the problem,an geology-engineering integrated management platform based on exploration-development collaboration,integrating geological research,engineering design and implementation,is established to address the geological characteristics and engineering difficulties in developing the reservoirs.An integrated technical system featuring“high-yield well design”(including reservoir modeling and well type selection,reserve assessment and well pattern construction,well trajectory optimization)and“drilling and completion engineering”(including risk forecast and optimal fast drilling,staged acid fracturing and support completion,reservoir description and tailer-made stimulation)have been set up to shorten well completion cycle and enhance productivity.As a result,two hundredmillion-ton-reserve zones(No.4 and No.8 faulted zones)have been discovered,verifying the technical strength of the system for the exploration and development of the Shunbei oil and gas field.References can also be gained from the implementation of the system for the development of other ultra-deep oil and gas reservoirs.
