摘要
针对动用低丰度、薄互层发育的油层,采用水平井技术,可冲破该类油田有效开发的技术经济界限.以大庆外围油田葡萄花油层为例,阐述了油藏描述中的测井、地震、地质建模等技术,井网优化中的数值模拟、经济评价等技术,单井地质设计及现场地质导向中的地质模型、随钻测井(LWD)、综合录井等技术.通过多学科油藏研究保证了超薄储层阶梯状水平井的56.3%含油砂岩钻遇率,实现了在1m左右的薄单砂层中穿行,水平井产量达到直井的3~5倍,取得了较好的开发效果.
It is an urgent and difficult technical problem that how to develop the oil layer that is in low abundance, thin interbed developed in the development of the Putaohua oil layer of outer-ring oil-field of Daqing. Using the horizontal well development technology has broken through the technical and economic limit of effective development of that kind of oil field. This paper elaborated the application of oil well logging, seismic, geological modeling technology in reservoir description; the application of numerical analogue, economic evaluation technology in the optimum of well pattern; the application of geology model, logging while drilling (LWD),compound logging technology in geology design of the single well and the scene geosteering, a series of multi-disciplinary reservoir research above had guaranteed higher drill meeting rate of oil sandstone of step-shaped horizontal well in the ultra thin reservoir. It realized walking through in about 1m thin single sand layer, the output of horizontal well is 3~5 times as much as the that of the vertical well.
