滴西17井区火山岩气藏火山机构解剖及识别技术
|
摘要
火山岩气藏作为一种特殊的气藏类型,已逐渐成为重要的勘探目标和油气储量的增长点。针对克拉美丽气田滴西17井区火山岩气藏内幕结构复杂、经历多期多类型改造的特点和边界不清晰的解剖难点,应用复杂火山岩内幕解剖技术,综合露头、岩心、测井、地震等资料,突出井点约束和地质模式控制,通过单井模糊界面识别、剖面精细标定与追踪、平面多属性圈定、空间多角度精细刻画,精细解剖了滴西17井区火山机构内幕,揭示出各结构单元的形态、叠置关系、规模和分布规律。
As a very special one,volcanic-rock gas reservoir becomes not only an important exploration target but also a new growth point for oil and gas reserves.After experiencing multi-phase and multi-type reforms,the volcanic-rock gas reservoir in Dixi 17 well block,Kelameili gasfield,is characterized by complex internal structure and unclear boundary.So,it's difficult to appraise it.Combining outcrop observation,core analysis,along with well-logging and seismic data,a lot of appraising technologies are implemented for this reservoir to further reveal the shape,stacking relation,scale and distribution rule of every structural unit,such as constraining outstandingly the well site,controlling the geological model,identifying the fuzzy interface of individual well,calibrating and tracing the profile,delineating the multiple attributes of plane,and describing finely the space.
