Application effectiveness of new horizontal well technology in tuha oilfield

Since 1996,the new technology for horizontal well has been popularized in Tuha oilfield,which makes the technology widely used and achieves good result.In the practice,by probing,summarizing and improving,a set of technology and method suitable for the different reservoirs at Tuha oilfield is established,in which,the technologies of horizontal well geology design and orientation are introduced,so that the application of horizontal well in Tuha oilfield is ensured and the progress and development of the technology is enhanced.The cases such as highly effective development of bottom water reservoir in Hongnan oilfield and breakthrough of deep heavy oil reservoir development suggest the technology discussed is of practice and effectiveness.
