Research Of Constitution Character And Evaluation For Object Drilling In Jin-hu Hollow

At present, three-dimensional seismic exploration applied in most of oil-fields. Constitution reservoir as the main objective of oil-gas-exploiting, have the character of high degree of exploiting. Especially in Su-bei baisn have entered the stage of very hard.Thesis, Jiang-hu oil-field small fault block reservoir characteristics and the status of Lake depression at this stage of exploration, through the mechanism of tectonic activity on the Lake Depression, process analysis and a large number of integrated interpretation of seismic data, summarizes the tectonic style Jin-hu depression type, fault distribution law of control on hydrocarbon accumulation effect. Jin-hu depression is divided into the early tertiary faults, post-and long-term activities (mainly referring to on going activity, not including two faults inherited) faults in the process of hydrocarbon accumulation plays a countercheck respectively, the role of communication and destruction. This paper researches interpretation methods of model-guided and the models of construction, including Jin-hu depression study and interpretation ideas and methods. The structural characteristics (tectonic evolution, fault system, etc.) and exploration potential and favorable exploration targets in Jin-hu hollow have been researched focally.The purpose of this paper is that, firstly, systematically analysis the feature of the Jin-hu concave via the research of the thesis; secondly, indicating the next orientation of the potential excavation, and providing the target of the drilling from the view of the structure. Therefore, in the research to this project, we launch numerous structure interpretation and target evaluation task through closely combining the past exploratory work. By means of one year's research and practical application, this project team drilled four preparatory reconnaissance borehole which are all successful. So the success ratio comes to 100%, and we acquire well benefit. The interpretation method and knowledge which obtained by the project research have enormous meaning of guide to the prospecting of the Jin-hu hollow.
