Abstract:Eccentric BHA is a new deflection controlling tool. It’s difficult for us to analyze the stress of eccentric BHA. The paper probed into the theory model of it. The eccentric BHA based the theory model was carried out field testing in Liaohe Oil Field. Good results have been gotten. Borehole deflection was controlled and high penetration rate was also kept.

Abstract:Developing and taking advantage of geothermal resources is a systematic project of high investment. Several drilling techniques for decreasing investment and increasing development benefit of geothermal resources were approached after analyses on current situation of geothermal resources development in Daqing Oilfield. Well structure optimization techniques, horizontal drilling techniques and branch hole drilling technology have great potential application on developing different hot water zone. The new way to use the clear energy of geothermal energy is also approached. The main attentions put on the well structure optimization of Well Sare 2.
