Research on the torsion impact generator for speeding up drilling in deep formation of Yubei area
摘要
Abstract
Due to the great burying depth, larger than 4000m, and hard Shajingzi formation with strong abrasiveness and poor drill-ability in Yubei area of Xinjiang Province, it is hard to speed up drilling operation, Previous practice shows that the cone bits have a poor impact on the Shajingzi formation and the conventional PDC bit has high anti-torque, so it is easy to produce“stick-slip”phenomenon. Finally, the rock breaking is inefifcient. In order to improve the penetration rate and reduce the cost, TorkBuster torsion impact generator with a personalized PDC bit is recommended. The three drilling technologies,"PDC bit+screw drill tool","diamond bit+turbine tool"and"torsion impact generator+PDC bit”, are discussed in the paper. The results show that torsion impact generator is more effective than other drilling technologies, with the average rate up to 6.42m/h, 200%-300%higher than earlier stage. The torsion impact generator overcomes the deep drilling problems in the high-strength plastic formations. It should be widely applied.关键词
