摘　　要：为了厘清构造控油气作用,经地震构造解释、断层性质、断层组合形式及油气层纵横向分布规律等研究,认为花场气田具有双层结构,对油气分布的控制作用明显,上层构造系统为油藏,下层构造系统为气藏。为了准确判定油气藏类型,在地质特征研究的基础上,针对复杂的油气情况,利用相态图法、戊烷以上烃组分总和(C_(5+))、储层烃流体组成的组合参数(Φ_(1))值、流体性质分析等方法,结合试油试采,对花场气田油气藏进行综合判定,最终确定油气藏类型:油藏为常规油藏,气藏均为无油环高、特高含凝析油凝析气藏。In order to understand the control of structures on oil and gas,based on the research of seismic structure interpretation,fault properties,fault combination forms and vertical and horizontal distribution laws of oil and gas layers,it is believed that Huachang gas field has a double-layer structure,which has obvious control over oil and gas distribution.The upper structure system is oil reservoir,and the lower structure system is gas reservoir.The type of the oil reservoir and gas reservoir in Huachang gasfield is determined by means of phase behavior graph analysis,C_(5+)analysis,Φ_(1) value analysis and fluid property analysis,based on the study of geological characteristics and the oil test and production test results.Finally,it is determined that the oil reservoir is a conventional oil reservoir,and the gas reservoir is a condensate gas reservoir without oil ring and with high or ultra-high condensate content.
