The exploration and development practice in Shunbei area of Tarim Basin shows that oil and gas resource there is rich. However

the reservoir is deeply buried

the degree of oil and gas enrichment varies greatly

the reservoir type is very complex

and the overlying strata has the engineering problems such as easy leakage and collapse. All these problems above bring great challenges to the efficient development in this region. In order to expand the scale of oil and gas and realize the efficient development

the exploration in organizational management and work model has been carried out. The main practices and corresponding technologies of key links such as management mode

well position demonstration

well type design

safe drilling and effective well completion have been initially formed. The research will give reference for development of the ultra-deep fault- karst reservoirs in this area and similar reservoirs.
