| In China most of the gas reservoir belongs to the closure of the elastic water drive gas reservoir,In.the development of different degree of formation water property.Make gas field in the case of recovery degree is not high in advance into the decline stage,or even cause gas well water flooding Wells,Due to the interference of formation water,Ultimate recovery effect gas field,So how to improve the recovery efficiency of water gas reservoir,At home and abroad has long been dedicated to research and solve one of the main topics.With deepening YiTong basin oil and gas exploration of knowledge,technological progress,the natural gas in the basin are good signs,Current industrial gas Wells have been found in YiTong basin,a total of 41,70 layer,the layer in terms,wanchang · group,younge,luxury ridge group,shuangyang group has distribution,present the gas everywhere,layers of gas,Shows the YiTong basin has great potential of exploration and development of natural gas.Because YiTong basin is currently in exploration and development in the early,there is more to solve the problem,there is more to solve the problem,in fracture is complex,the poor quality of seismic data,horizon tracking difficult,structure interpretation is difficult,sedimentary superimposed fan body,stratigraphic correlation is difficult,complex gas reservoir control factors,study hard,logging series more controlled factor,fluid identification is difficult,less data of old well,easy to leak oil and gas layer.This topic through to liang’s typical gas reservoir fine anatomical structural belt,through the combination of dynamic and static research train of thought to study the accumulation of natural gas enrichment regularity,the law of producing gas well production and out of the water to see,finally to put forward reasonable Suggestions to quickly see well,evaluate the natural gas development potential,for the next step is the extension and potentialities and provide technical support. |
