The Research Of The Structural Styles And Evolution In HongQi Sag Hailar Basin

Oil and natural gas generation, migration and accumulation and geological structure has a close relationship. In oil region, construction activities through the sedimentary environment control can lead to the formation of source rocks, tectonic subsidence role in the source rocks buried deep under the conditions to achieve a source of oil and gas, rocks and broken the oil and gas migration to provide a channel And path, structural stress is the major driving force for oil and gas migration, structural traps for the oil and gas gathering provides a venue and conditions, accompanied by tectonic reservoir formed the whole process. Therefore, in oil and gas field exploration and development process, the geological structure is necessary to first consider the question.Construction activities on the basin of the formation of sedimentary facies and the distribution of oil and gas migration and the formation of reservoirs has always played an important role in the control of the fracture, inadequate understanding of structural features, will directly affect the deployment of exploration and decision-making, therefore, to Structural analysis of the evolution of oil and gas migration, the accumulation of great significance.Daqing Oilfield is the Hailar Basin oil and gas resources in preparation for one of the areas of strategic focus, Hulun Hu - Chagannuoer, Bayanhushu, the red flag, shouting and the Lake Basin fault is the fault of 16 more prospects for the area. However, Hailar Basin experienced a multi-phase construction and transformation of the basin, the complex fault system, it is difficult to see the face of the prototype basin. Depression which means great potential for exploration, research higher degree, the better the prospects for exploration is one of the Depression, is the recent breakthrough in the exploration of the important objectives, namely oil and gas resources could become a growth point. Many scholars made a lot of research work, put forward a series of new ideas, but has not been unified understanding.This paper is a red flag for depression in Hailar Basin in the structural interpretation of seismic data research. Hailar Basin to the red flag has been the Depression and two-dimensional seismic data logging, drilling and other data and previous research results as the basis, sequence stratigraphy new geological theory and the guidance of structural geology, integrated petroleum geology, Sedimentology, and other geophysical theory and advanced technology, from the perspective of evolution, and tectonic evolution of sedimentary basin evolution of organic integration, unity and seismic drilling hierarchical stratification, the T04, T1, T2, T22, T3, T5 6 major unconformities in the seismic profiles on the track contrast explained that the establishment of high-precision means depression, such as when the formation of the framework; several major unconformity interface with the formation of the main line, cutting relations on the fault , Distribution of, a period of rupture understand the area of distribution and evolution; implementation of structural details, analysis of structural style and tectonic evolution, summing up the evolution of Hailar Basin phase of the structural features through the system to red flag Depression Research, deepening the structural characteristics of the fracture zones, construction and development of the understanding, to deepen the depression of the red flag of the Petroleum Geology of understanding, enabling optimization of oil and gas zone, ready to break the conditions for exploration.
