Abstract: Biqian 67 block of Xinzhuang oilfield is located in the eastern part of the northern ramp region in Biyang sag, and is just at the intersection point of the NE- trending N - dipping normal faults with the NE - trending S - dipping normal faults, where the fractures are well developed and the structures are highly fragmented. The distributioncharacteristics of the structures and fractures, the distribution patterns of the reservoirs and oil and gas, as well as the scale of reserves in this area are further materialized through integrated geologic and seismic study. Considering that the reservoirs are highly permeable, the burial depths of oil layers are shallow, there are many oil - bearing layers, the thickness of pay zones penetrated in single well is large, the vertical oil- bearing intervals are long, and the reservoirs contain extra - heavy oil, the oil- bearing blocks with confirmed oil reserves are systematically developed by using the advanced drilling and recovery technologies, such as deviated well, vertical well and steam huff and puff. The development effects are quite good.
