Abstract: During the reservoir description of the Xiyuan-Cuizhuang faulted reservoirs in Jinhu Depression,the authors postulated an integrated exploration technique of proving a fault block with only one well.This technique is applied to solve difficult geological problems in exploration of small fault blocks in complicated geological environments by using available common information of geology,seismics,well-log and well-test.It improves greatly oil prospect efficiency with a shortcut of the way between oil exploration and development.The technique consists of seven research contents as follows:(1) studies of fault structure and stress field are to expound the structural forms and evolution;(2)researches on sedimentology of the reservoirs are to determine the genetic types and geometric sites;(3)analysis of micro-structure of the reservoirs is to study the anisotropism of the diagenesis and pore structures of reservoir;(4)prediction of distribution of reservoir parameters in the fault block is to point out distribution of the lithological data,petrophysical data and oilbearing features of reservoirs in 3-D;(5)determination of oil-water contact is to draw the boundary of oil-existing area;(6)investigation of the fluid properties is to explain the effects of oil and water on oil productivity and genetics of the fault oil pools;(7)calculation of oil reserves and evaluation of the fault-block pools are to submit the proved oil reserves and various parameters for development planning of the fault-block pools.This technique has been thoroughly applied in the Xiyuan-Cuizhuang area.All of the results have been used in the development planning and proved by the production well framework,which presents great economic and social benefits.
