庆北深层天然气勘探开发工程技术进展及今后攻关方向

Deep Natural Gas Exploration and Development Engineering Technology Improvement and Its Further Development in Northern Daqing Oilfield

文章系统介绍了大庆油田北部徐家围子地区深层天然气勘探过程中由于地质构造和地层岩石性质给地震、钻井、固井、测井作业造成的技术难题,以及为克服这些技术难题而组织的技术攻关、现场试验所取得的成就和技术进展。目前,这一地区已经成为我国第五大天然气区,为加快此区勘探开发步伐,实现大庆"建设百年油田"、"以气补油"、"油气并举"的战略目标,作者对今后该区工程技术的发展方向和有关细节提出了相应的意见和建议。

This paper systematically introduces the problems in seismic,drilling,cementing,and logging operations due to geologic structure and rock property in the strata during the exploration for deep natural gas in Xujiaweizi Zone in northern Daqing Oilfield.It also discusses the achievements and advances in the development of technology and its field application.Now Xujiaweizi Zone has become China's fifth largest natural gas zone.The author in this paper gives appropriate comments and suggestions on the development direction and some details of the engineering technology for the zone,with an aim to accelerate exploration and development in the zone and achieve the goal of 'uilding a 100-year oilfield','upplementing oil with gas,and 'ncreasing oil and gas'in the Oilfield.
