The Geological Research And Exploration Objectives Of Chenjiazhuang Dongpo Uplift

Chenjiazhuang Dongpo is the Chen Uplift tendency terminal region which has a little fault, so it is difficult to come into being good structure for oil. In the early time there were some exploratory wells in this area, but they all failed. So Guantao reservoir area has no significant progress.Chenjiazhuang oilfield has been discovered in the west recently, and oil and gas are reserved in the top, the first and second sand strata, of the Guan's infrastructure which is confined by the district cover.So oil and gas are distributed in the segment of 50 meters below the first mud strata of the buried mountain. At the same time they are limited by the overlap strata and riverway sandstone so the reservoir belongs to the structure reservoir which is controlled by the lithology. So it is thought that The east and west have similar geological characteristics and structural features. So it should have the same condition, then this area is more favorable exploration prospects.This paper does research in Chenjiazhuang Dongpo by using seismic exploration method, especially seismic coherent body and seismic attributes and so on, makes reservoir prediction, at the same time, and evaluates of the target zone.During the study in order to link geophysics and geology there are using several ways, such as combination of density log and interval travel time, and multiple element colligation demarcation. Simultaneously using coherent body and procession of the coherent data could know well about the development of the fault and the rule of the throughgoing, then complete the explanation of the fault.It could decrease the ambiguity and extract correlation parameter by taking advantage of standardization and optimization of the seismic attribute. Based on this, there are"experts'system depending on the knowledge"and"statistical way to attribute"to apply to seismic attribute, and it could provide powerful geology evidence by using three-dimensional display of data volume, associating geology, well drilling, logging to achieve the change and identification from seismic facies to sedimentary facies.Through a detailed study of the target, there are enabling the prediction and evaluation of some specific drilling wells.
