Research On The Structural Characteristics And Reservoir Forming Modes Of HeiDimiao Oil Layer In X Region

Gulong depression is located in the western part of the central depression of the Songliao Basin,and is a secondary tectonic unit of the basin.It is a long-term inherited depression.The X-work area of this study is located in the northern part of the Songliao Basin.In this paper,the three-dimensional data of X-work area in Gulong depression are used as the basis of seismic data,and the data of earthquakes,geology and drilling are taken into account.The research on improving the small fault and micro-amplitude structure is carried out.In this interpretation,the three-dimensional seismic data of the Gulong sag has been explained with high precision,which has overcome many problems such as the large number of work areas,the lack of uniformity of seismic data,the lack of structural interpretation accuracy and the lack of reservoir prediction accuracy.On the other hand,the lithology of the middle and shallow stratigraphic groups is stratified and the spatial identification and characterization of the single sand bodies are carried out.This paper analyzes the sedimentary rules and reservoir characteristics of the Heidimiao oil layer in the Gulong area,and summarizes the reservoir formation mechanism of the Heidimiao oil layer in the study area,through the comprehensive analysis of the conditions such as the reservoirs,And the reservoir formation model,and the favorable area of the study area was predicted.(1: 2.5 million,line distance 2m);the formation of the micro-amplitude structure and the ability to explain the small fault of the technology and the development of the top of the three high-precision tectonics,Flow,can identify the vertical fault distance ? 3m,the construction amplitude ? 4m of the fault and structure;submitted to the Gulong area Black Tomb Temple oil tectonic pattern classification diagram fracture growth index profile,fault system division map,oil source fault map;And the distribution of oil and gas in the area of the Heidimiao oilfield in the Gulong area was predicted...
