Title: Horizontal well development technique and its practice for complex fault-block reservoirs in Jidong Oilfield
Abstract: Jidong Oilfield is a complex small-fault-block reservoir in the fault basin of Bohai Bay.On the basis of the fine description of the reservoir,the newly developed horizontal well technique is generalized and applied with the application scale speedily extending and satisfactory achievements.A series of techniques suitable for the features of the reservoir are formed,including adaptable evaluation of horizontal wells,scheme deployment,design,drilling,well logging,borehole log,oil production and production management etc.The utilization of the complete techniques ensures the result of the horizontal well development technique in Jidong Oilfield and paves the way for its further advancement.The workability of the method is proved by the reservoir with multi-reservoir,small fault-block,bedded edge-bottom waterflood in Gao 63 fault block of the south area in the shallow formation in Gaoshangpu Oilfield,the highly effective development of the difficult-to-produce reserves in Ng_(8) subzone of the reservoir in the north area,and the practice of improving the development efficiency in maturing oilfields by the slim-hole sidetracking horizontal well.
