灰色理论在油气钻井成本预测中的应用
In order to reduce drilling cost and economical and efficiently exploit peripheral virgin reserves in the Daqing Oilfield, test researches on surface-casing drilling technology are started, including the general proposal and techniques of casing drilling, casing string structures and accessories, downhole tools and special cementing tools.
为了降低钻井成本,实现外围未动用储量经济有效地开采,大庆油田开展了表层套管钻井技术的试验研究,包括套管钻井总体方案及工艺、套管串结构及其附件、井下钻具及固井专用工具的开发研究。
Because of the deep buried depth and small reservoirs of Anpeng oilfield, and in addition to the downhole troubles such as stuck pipe in the slim hole and lost circulations caused by improper use of polymer drilling fluid, the drilling cost was very high and thus iimited the development of the oilfield.
