New screening method for reservoir by CO_2 injection miscible flooding

注CO2混相驱是一种提高原油采收率的重要手段,实施该方法的关键是筛选出具有开发潜力的油藏。目前,在注CO2混相驱油藏的筛选上,缺乏统一的筛选指标和筛选方法。通过对国内外注CO2混相驱油藏开采情况的分析和对比研究,选取了影响注CO2开采效果的12个筛选指标,利用概率与数理统计方法提出了筛选指标的评价标准,并应用模糊优选理论和模糊层次分析法,建立了区间数注CO2混相驱油藏筛选模型。应用该筛选方法对6个典型的候选油藏进行了筛选排序和综合评价。结果表明,该方法能够客观地评估油藏注CO2开发潜力的大小。CO2 injection miscible flooding is an important method for enhanced oil recovery(EOR).It is important to screen out the potential reservoirs for using the method.Now,there aren t uniform screening indexes and method about screening out CO2 injection miscible flooding reservoirs.Based on the analysis and researches of the CO2 injection miscible flooding reservoirs,12 indexes affecting CO2 injection miscible flooding results were picked out.By the method of probability statistics,the assessment criterions were brought forward.And combining with fuzzy optimum and fuzzy analytical hierarchy process(FAHP),the interval number screening model for CO2 injection miscible flooding reservoirs was successfully established.This screening method was used to screen and assess six classical candidate reservoirs about CO2 injection miscible flooding.The results show that the method could perfectly evaluate and screen the potential of CO2 injection of the candidate reservoir.国家自然科学基金项目(40472156

DISCRIMINATION OF METHANE HYDRATE DISSOLUTION AND DISSOCIATION IN SEA WATER AND ITS GEOLOGICAL SIGNIFICANCE

甲烷水合物的溶解和分解过程是甲烷水合物成藏的关键科学问题,同时也是造成环境灾害事件的重要因素。近年来,在阅读甲烷水合物相关文献中发现有些作者对甲烷水合物溶解和分解的复杂动力学过程产生了一些混淆,并由此可能对甲烷水合物的成藏机理及其对环境气候变化影响的认识造成偏差。基于前人的大量研究成果,并结合作者多年对甲烷水合物形成和分解动力学过程的系统研究,认为海底存在一种甲烷气体的动态存储与排泄平衡作用,甲烷水合物的溶解和分解是海底甲烷气的主要排泄方式,也是甲烷水合物失稳后的2种不同的重要过程,同时,海底甲烷气的排泄量、运移方式和排放速率都与甲烷水合物成藏与否密切相关,因此深入认识甲烷水合物溶解和分解过程的控制机理,对海底甲烷水合物形成机制、成藏过程的研究和对全球碳循环、气候变化的评估有着重要的科学意义。The dissolution and dissociation of methane hydrate in seawater are key scientific problems in the formation mechanisms of methane hydrate.They are also the important factors causing environmental disasters and geologic hazards.In recent years,there was some confusion in literatures about the kinetics of dissolution and dissociation processes,and there were some warped understanding of their influence on methane hydrate formation and global climate change.Based on a lot of research results,we think that marine methane has a homeostasis between storage and drainage.And dissolution and dissociation are the major dejection manners of methane hydrate.It is critical to realize that the both are two different processes.In addition,output,migration manner and drainage rate about marine methane are all related to the formation of methane hydrate.Therefore,it is important to discriminate the kinetic processes of methane hydrate dissolution and dissociation in seawater.国家自然科学基金项目(编号:40472156);; 教育部厦门大学“211”工程项目;; “985”二期工程资助项目联合资

近年来,随着常规油气藏勘探难度和勘探风险日益增大以及火山岩油气藏的不断发现,火山岩油气藏作为油气勘探的一个新领域,已引起了石油界的普遍关注和高度重视。以往的研究大多集中在研究喷发岩的地震信息识别及其与油气的关系,研究侵入岩的地震信息识别及其与油气的关系具有重要的理论与现实意义。通过对典型地震剖面的研究,识别出了岩株、岩盖、岩床和岩墙4种产状的侵入岩岩体,阐明了它们的地震信息识别特征,同时分析了不同产状的侵入岩与油气的关系,论述了8种与侵入岩有关的油气圈闭类型。In recent years,the difficulty and risk have increased in exploration for the conventional petroleum.With the continuous discovery of the volcanic reservoirs,volcanic-related rock reservoirs have become a new field of hydrocarbon exploration,and have greatly attracted the attention of the petroleum geologists.Former researches mostly focused on the seismic character identification of extrusive igneous rock and extrusive igneous rock-related reservoirs,therefore the study of seismic character identification of intrusive igneous rock and intrusive igneous rock-related reservoirs has an important theoretical and practical meaning in hydrocarbon exploration.Through the comprehensive research of the typical igneous seismic profiles in Qiongdongnan basin,the stocks,laccoliths,sills and dikes were identified from other seismic characters,and their identification characters were also summarized.Finally by the analysis of their implications for hydrocarbon systems,eight kinds of intrusive igneous rock-related traps were proposed.“973”项目“南海深水区盆地运源碎屑岩沉积机理研究”(编号:2009CB219407)资
