生物礁滩在碳酸盐岩地层的分布预测

生物礁作为油气的储集体,被称为储集油气资源的"天堂",在全球范围内,许多大型油气田都是生物礁油气田。然而,在油气勘探中,生物礁预测一直是个难点,过去预测的生物礁其钻井多数落空,在现有的生物礁滩中,90%以上都属于随机钻遇。利用地震剖面反射结构分析方法对生物礁体的识别具有解释速度快、可靠性高等特点,如果能够提高甚至解决礁滩相的预测问题,重视生物礁油气田勘探的研究,对我国油气的勘探将产生深远的意义,在一定程度上,对于缓解我国油气资源的供需矛盾,以及促进经济可持续发展具有重要意义。

Prediction of the Distribution of Biogenic Reef Flat in Carbonate Formations

As the reserving body of oil and gas, biogenic reef is called the ＂paradise＂ of oil and gas reserving. Around the globe, many large oil and gas fields are biogenic reef fields. However, the prediction of biogenic reef has been a difficulty in oil and gas exploration. Most of the biogenic reefs predicted in the past turned out to be a failure. In the existing biogenic reef flats, more than 90% are got by random drilling. Using seismic section reflection structure analyzing method to recognize biogenic reef body has the advantages of rapid interpreting speed and high reliability. If the prediction problem of reef flat can be improved or even solved, it will be of great significance to value the research of biogenic reef oil and gas field exploration for China＇s oil and gas exploration. It can to some degree reduce the imbalance of demand and supply of oil and gas and promote the sustainable development of economy.
