【摘要】 近几年来,针对华北油田逐年勘探领域和勘探对象由中浅埋深的构造圈闭向埋藏较深的岩性、地层油气藏勘探转移的现状;为满足岩性、地层油气藏勘探的需要,在完善应用成熟勘探工程配套技术的基础上在勘探实践中初步形成了针对复杂地区中深层构造-岩性油藏勘探的高精度三维地震采集技术、处理技术、深井小井眼钻井配套技术、低渗储层压裂配套技术等4项主导配套技术,为岩性、地层油气藏勘探取得突破性进展提供了重要的技术保障。更多还原

【Abstract】 In the recent years, Huabei Oil Field has gradually focused exploration on the lithologic and strati-graphic oil and gas reservoirs with large buried depth instead of the structural traps with small and middle buried depth. To meet the demand for exploration of the lithologic and stratigraphic oil and gas reservoirs, the oil field has developed four items of dominant technologies-high-precision 3-D seismic data acquisition and processing technology, systematic deep-well and slim-hole drilling technology and low-permeability reservoir fracturing technology. Those technologies helped make breakthroughs in exploration of lithologic and stratigraphic oil and gas reservoirs.更多还原
