摘要
如何在现场通过气测曲线,直观地判别所钻地层的干、湿气层,划分油、水层及油水界面,为勘探开发提供快速决策服务,是气测录井的重要研究目标,气测气体比率法为这一目标的实现作了有效的探索和尝试。这一解释评价方法是利用轻—中、轻—重和重—中烃气的比率三条曲线的走向及交汇情况来评判划分储集层。用标准组合特征图进行了说明,并以应用实例,验证了该方法的可行性和有效性。该方法为扩展气测解释评价方法作出了有益的尝试,使解释评价直观快速。该解释方法是由法国地质服务公司研发的,该公司推出的GZG型钻井液脱气器和ReservalTM色谱分析仪,为该方法的实施提供了条件。
At wellsite, through gas logging curves, how to intuitively discriminate dry and wet gas layers of the drilled formation and divide oil beds, water beds and oil-water contact to provide rapid decision service for exploration and development has become the key research topic for gas logging and gas ratio method of gas logging made an effective study and try for this aim′s realization. This interpretation and evaluation method judged and divided reservoirs with making use of the trend and crossing situation for the three ratio curves of light to medium, medium to heavy and heavy to medium hydrocarbon gases. The paper illustrated this method by standard combination characteristic chart, and verified its feasibility and validity with applied samples. The beneficial try was conducted for extending gas logging interpretation and evaluation methods, making interpretation and evaluation visual and fast. This gas logging ′s gas ratio interpretation method was studied and developed by Geoservices. GZG Drilling Fluid Degasser and Reserval TM Chromatograph, produced by Geoservices, provided conditions for implementing this method.
