摘要
孔南地区位于黄骅坳陷风化店构造带西南部,构造复杂,火成岩储集体规模大、厚度变化大且岩性致密,纵向上主要分布在孔店组一段和中生界。以工作站技术为依托,建立了一套以处理地震信息为主的火成岩储集体综合解释技术,包括地层对比、层位确定、构造精细解释和综合解释。在孔南地区火成岩油藏滚动勘探开发中,用这项技术解释了家8井区和枣22自然断块火成岩储集体,并用模式识别技术对它们进行了含油气性模式识别,预测均为有利含油区。这2个特殊类型油藏新钻井的试油结果证实预测可靠,投入开发后取得显著经济效益。综合解释技术在孔南地区火成岩油藏研究中得以成功应用,其基础是对该区地质规律的深入认识,关键是要从井出发,充分利用多种信息、多种方法,进行综合分析和综合解释。图4照片1参1(王孝陵搞)
Kongnan area is located on the southwestern part of Fenghuadian structural belt, Huanghua sag,and is charcterized by complicated structures. This igncous rock reservoir is large in size, with variable thicknes and compact lithology. It is mainly distributed in Mesozoic and K1 Formation.A set of comprehensive interpretation techniques dominated by seismic data processing technique on work station and interactive technique are established, including formation correlation, formation identification, sophisticated structural interpretation and comprehensive interpretation. In the progressive exploration and development of this igneous rock reservoir in Kongnan area, this set of tecdniques are used to interpret the ignoous rock reservoir in Jia8-Well Block and Zao-22 natural fault block and the pattern recognition technique is used to identify the oil and gas potential. Boh of them are predicted as favorable oil bearing area. These reliable predictions have been confirmed by production test results of newly drilled wells in these blocks. The successful application of this interpretation technique to the igncous rock reservoir in this area is based on an in-depth study of geoloic regulations.The key to success is fully utilization of various information from every well and using various methods to make comprehensive analyses and interpretation.
