大庆古龙油田地面建设新模式

New Construction Mode of the Surface Facilities in Gulong Oilfield of Daqing Area

随着大庆油田进入持续4000×104t/a稳产阶段,外围低产油田的开发比重逐年加大,探寻外围低产低渗透油田的有效开发模式至关重要。古龙油田是大庆西部油田近年来最大的开发区块,具有外围油田"油藏深、产量低、凝固点高"的特点,开发建设的11个区块分布零散、系统依托性差。为使古龙油田得到有效开发,坚持地上地下相结合,系统布局与零散建设相结合,通过多种建设模式、多方案比选的方式,确定适宜古龙油田开发的最终建设模式,提高了开发效益,取得了良好效果。

With the Daqing oilfield came into the sustainable and stable production stage of 40 million tons per year,the development ratio of peripheral low yield oilfields increased year by year,the research of the effective development mode was crucial for the low-yield and low-permeability oilfield in Daqing peripheral area.Gulong oilfield was the biggest development block of Daqing west oilfields in recent years,with the characteristics of peripheral oilfields,such as'deep oil reservoir,low yield,and high freezing point'.Gulong oilfield was composed of 11 blocks,which were in scattered distribution and in unfavorable support condition.In order to ensure the effective development of the Gulong oilfield,on the basis of combining the oil reservoir engineering and the surface engineering,and combining the system layout and the scattered construction,the final construction mode suitable for Gulong oilfield was determined by the comparison and selection of a variety of construction modes and plans.The development efficiency was improved and good results were achieved.
