Characteristics Of The Structure And Its Control Effect On Remaining Oil In The Xingbei Area

Fault segment linkage is universal, because the seismic resolution limit, two common fault segmentation is interpreted as a fault phenomenon. The evolution and growth mechanism of fracture control the formation and distribution of broken ring. Along faults developed positive micro range structural types are mainly two kinds of, a kind of is affected by fault segment control of development in the footwall of the transverse anticlines and a is by fault connection control point of development in the hanging wall of the fault transverse anticlines. Along fault department due to the fault characteristics(strike, dip, and dip and fault distance) and characteristics of sand bodies(orientation, type, size) differences, resulting in different tectonic background of fault and sand body configuration relationship of remaining oil control effect difference larger. In depositional time unit plane sedimentary micro phase, single sand body identification, fine structure research based on, combined with injection production well pattern, dynamic development of injection production relationship and tapping the potential of remaining oil in the sum of analysis, find out the remaining oil enrichment site and type and development potential layer and position.
