Study On The Technology Of Numerical Simulation In Chang-6Reservoir In Buziwan South Oil-field

JiYuan oil-field is one of the Erdos Basin Mesozoic oil layer development of source area. After nearly30years of exploration and development, it has gradually stepped into the middle of oil-field development. In recent years, low individual-well producing rate, instability of production and recovery efficiency have become prominent problems in the process of oil-field development. How to develop the chang-6reservoir in the south of the BuZiwan oil-field more scientifically, rationally, effectually, has great significance for increasing the general developing level and benefit of this oil-field and making the JiYuan oil-field become the fourth big hundred million ton oil-field in Erdos Basin. So, it’s very necessary to study the technology of petroleum reservoir simulation development in Chang-6reservoir in BuZiwan south area.This paper gives a comprehensive analysis to Chang-6reservoir in BuZiwan south area about the aspect of reservoir geological characteristics, according to the oil reservoir geology modeling technology, builds a detailed three-dimensional geological model area by using the Petrel software, and then carries out a numerical reservoir simulation research on this block.In this paper, well pattern system, water shutoff profile control and reservoir pressure system will be studied by using the method of reservoir engineering and numerical simulation, and then provide theoretical support to the adjustment of the development technology. The research result indicates that geological reserves of Chang-6is1750.1×104m3;480m×120m anti-nine-spot well network will be best for this block, injection-to-production-well ratio is1:3; the best crack and a half long is46.2m; the reservoir average thickness is12.4m, single well day injection is between15-20m3/d. The result of this article can provide the theoretical guidance for achieving high and stable production of the Chang-6reservoir in BuZiwan south area, and also will have certain reference significance for efficient development of other ultra-low permeability reservoir...
