摘要
本文针对牛庄油田深水浊积砂岩储集体规模小、厚度薄、埋藏深等特点,发展了一套以地震信息为主的薄层砂体综合解释技术,在无对比标准层,测井曲线和岩性特征无法对比追踪储层的情况下,薄砂体解释技术在岩性油气藏滚动勘探和开发中,是一种有效的、具有经济意义的技术措施。在牛20开发试验区用这项技术解释了3个砂体,经钻井证实,预测的深度和厚度可靠,投入开发试验后也取得了好的成效。该技术的成功应用,是建立在对该区地质规律,如砂体分布、地层剖面结构等深入认识的基础上的。从井出发,充分利用多种信息、多种方法进行综合分析和综合解释是成功的关键。
In view of the small, thin and deep-buried features of the turbidite reservoirs in Niuzhuang oilfield ,this paper sets up a kind of synthetic technique which interprets thin turbidite sandbody by means of seismis data .Due to the lack of marked bed well log and lithology cannot be used to trace the reservoir formation .The technique of thin sandbody interpretation is a realizable measure with particular economic significance in lithologic oil pool exploration and development .Three sandbodies are interpreted in Niu 20 test area, drilling confirms that these sandbodies are located at the expected depth with thicknesses very close to the predicted ones. The successful application of such an interpretation technique is based on the geology regularalities ,such as sandbody distribution, formation section and so on. The key to the success is that starting from a well ,a synthetic analysis and interpretation with geology, well log and seismic data are analyzed and interpreted comprehensively
