摘　　要：针对A深水油气区块CPEDC2段为相态变化复杂的凝析气藏开采困难和经济可行性低的问题,在考虑采出程度、经济效益、工艺技术等因素的基础上,采用油藏数值模拟技术和数据分析法,进行了CPEDC2段油气同采、先开采气后采油、先采油后采气等开采顺序研究和CPEDC3段不同井型转注水井的研究,最终得出CPEDC2以开采油环为主、而后才以衰竭式开发方式开采凝析气和黑油这种方式最为经济合理,CPEDC3采用后期采用水平井转注最为合理,对该区块后期开发调整也有重要意义。In allusion to the CPEDC2 segment of this block was a complex condensate gas reservoir with complex phase change and low economic viability. By using the method of numerical reservoir simulation and data analysis,on the basis of taking into account the degree of recovery,economic benefits,technology and other factors,in the period of CPEDC2 oil and gas same exploration,gas recovery after first mining,gas production after oil production research on mining sequence and to study on different types of layout of the block. Finally,it was the most economical and reasonable way for CPEDC2 to develop the first part of the oil ring and then used the exhaustion type,CPEDC3 was the most reasonable development. At the same time,it achieved important significance to the later development of the block.
