陈家庄凸起油气勘探潜力分析
|
摘要
分析了陈家庄凸起区的油气运聚条件和气藏分布规律,认为陈南断层在明化镇组沉积末期停止活动,有效地减少了天然气的溢散是形成陈家庄凸起区浅层气藏形成的基本条件,而气藏的分布受构造背景和沉积相带的控制;通过对勘探潜力的分析,认为陈家庄凸起的中部和盐家地区是浅层气的富集带,勘探工作的方向应该继续钻探已识别的Ⅰ类亮点,胜北断层二台阶成藏条件优越、勘探程度较低、中浅层气的勘探具有较大的潜力,陈家庄凸起西部应把重点放在成藏条件研究上,馆陶组地层圈闭是下一步的勘探方向。
The hydrocarbon migration conditions and gas reservoir distribution laws in Chenjiazhuang Uplift Area are analyzed. It is considered that the activities at the late stage of sedimentation of Minghuazhen Formation stops and effectively reduces the overflow and diffusion, which are the basic conditions for shallow gas reservoir formation in Chenjiazhuang Uplift, while the gas reservoir distribution is controlled by the tectonic background and sedimentary facies belt. Through analyzing the exploration potential, it is considered that mid Chenjiazhuang Uplift and Yanjia Area are the zones where hydrocarbon is enriched,its exploration orientation shall be focused on the recognized class I potential area, in Shengbei fault conditions of hydrocarbon accumulation are excellent and exploration degree is relatively low,potential is higher for mid-shallow gas exploration at the second step, and the study of hydrocarbon accumulation shall be emphasized in west Chenjiazhuang,while the traps in Guantao Formation are the targets for further exploration.
