松科一井(主井)钻探工程技术配套

设计井深1810 m、完钻井径157 mm、需在松辽湖盆穿透一层含油气构造的松科一井(主井)科学钻探工程,采取自制底架提升平台高度安装井口防喷设施、改造TJS-2000E型水井钻机升降系统提高设备起重能力、研制水力出心装置克服加长加重大口径钻具出心困难、引进石油钻井高速离心除泥机控制泥浆固相含量、根据工程条件无附件焊接套管表层固井等配套技术,成功地完成了国家"973计划"项目"白垩纪地球表层系统重大地质事件与温室气候变化"对工程的规定任务,为高质量、低成本实施大陆环境科学钻探工程探索出了一条可行之路。

Matching Technique for Drilling Engineering in Well-1 of Songliao Scientific Drilling

Well-1 of Songliao scientific drilling was designed with depth of 1810 m and finishing drilling in diameter of 157 mm.In this engineering,blowout-preventing facilities were equipped at wellhead by raising platform with self-made under-carrier;lifting capacity was improved by reforming lifting system of TJS-2000E water well rig;coring difficulty was overcome by the development of hydraulic coring equipment;mud solid was controlled by introduced high-speed centrifugation deslimer.Certain tasks in "major geological events in the earth surface system during the Cretaceous and greenhouse climate change" of "973 program" were performed and a feasible way was explored for continental environment scientific drilling with top quality and low cost.
