陆相断陷盆地储层地震预测技术优化
|
摘要
陆相断陷盆地是我国油气资源重要的聚集地,盆地具有复杂多样的沉积体系和储集类型。在济阳坳陷勘探实践中,逐步形成了针对不同类型储集体的地震地质综合研究技术系列。但随着勘探程度的提高,储层预测技术的精度和可靠度急需进一步深化。针对这一问题并结合现阶段主要勘探目标,本文提出了一套针对性的技术优化手段,形成了"定量统计分析明确目标地震地质特征;探井成败研究找出问题关键;适用条件评价发展有效解决方法;多学科综合分析降低勘探风险"的储层精细预测技术流程,在实际油气勘探实践中取得了显著的应用效果。
The continental rift basins are most important accumulation for oil and gas resources in our country.This basin has many composite deposit systems and diverse reservoirs.In the oil and gas exploration we step by setp formed a fairly complete series technology for seismogeology comprehensive researching about different storage categories in Jiyang seg.But by increasing degree of exploration,The existing series technology about seismic predicting of reservoirs urgent need further researching on precision and reliability.To solve this problem and combines main exploring object at present,this paper put forward a pointed optimizated techniques,formed"Use quantitative statistical analysising to point seismogeology characteristics of objects;use researching exploratory well successful or not to find the key question;use suitable conditions evaluating to develop permanent solution,use multi theories integrated analysising to reduce exploration risk"process for reservoir carefully prediction.Through oil and gas expiorated in Jiyang seg,With achieves obvious result.
