Matching Technique for Drilling Engineering in Well-1 of Songliao Scientific Drilling
Wenshi Wang · Exploration Engineering(Rock & Soil Drilling and Tunneling) · 2008
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.
