用现代测井技术提高油气勘探效益

测井技术是现代石油工业中高技术含量最多的技术门类之一。现代测井技术以系列化、数字化和标准化为标志，经历了数字测井技术（第一代，７０年代）、数控测井技术（第二代，８０年代）、成像测井技术（第三代，９０年代）３个发展阶段。沿着３代测井技术的发展脉络，叙述了其各自的特点、特长以及对地下地质情况的适应性，列举了３代测井技术在中国的应用实例。展望了第四代测井技术———信息测井技术时代的到来。认为，应用现代测井技术进行油气勘探，为世界石油工业带来了高效益。现代测井技术１０ａ更新一次，在油气勘探难度越来越大的中国，更应该加强现代测井技术基础实验和前沿技术的研究和投入，这是提高新区、新层系、新领域油气勘探效益的有效途径。

Raising the efficiency of oil and gas exploration by applying modern well logging technique.

Well logging technique is one of the branches which have more highly advanced technological content in modern petroleum industry. Taking seriation, standardization and digitization as its sign of development. The modern well logging technology has underwent 3 development stages: digitized well logging (the first stage, in 1970's) , numerical controlled well logging (second stage, in 1980's) and image logging (third stage, in 1990's). Along such a route of development of 3 stages their specialties and characteristics and their adaptability to subsurface geology actual examples in their application to Chinese petroleum industry are described. The arrival of a new era, the development of the fourth stage of informational well logging, is forecasted. It is considered that the apfield. Application of modern well logging techniques to oil and gas exploration gives high efficiency to the world petroleum industry. Modern well logging techniques will be updated once 10 years. As the oil and gas exploration in China becoming more challegible, input investment in basic experiment and frontal technical research should be emphasized, and this well be an effective way to raise the efficiency of petroleum exploration in new regions, new formations and new
