东营凹陷滚动勘探开发技术研究与应用
|
摘要
东营凹陷已进入勘探开发成熟期 ,滚动勘探开发是增储稳产的主要手段 ,精细油藏描述是其关键。总结滚动勘探开发的 4种方式 (老区扩边、发现新块、发现新层系和新区滚动勘探开发 ) ,对断块复杂程度提出按每平方千米内所有断层的累加长度划分的新方法 ,从构造描述、储集层描述和油藏描述方面介绍了滚动勘探开发的技术方法。以永 8断块为例 ,在层位标定、反射特征分析、构造描述流程、地震地质分析等方面进行深入分析 ,归纳精细油藏描述的具体方法 ,强调了三维地震数据体的相干分析、属性分析等技术的重要作用。应用这一滚动勘探开发技术 ,使东营凹陷每年新增滚动储量近2 0 0 0× 10 4 t。图 3参 10
For oil and gas exploration and development in the developed sag, progressive exploration and development should be a major tool for improving production and tapping production potentials of the area, in which an accurate and detailed reservoir description will be the key progress. By analyzing the progressive exploration and development reservoir types and basic features, four styles of progressive exploration and development are summarized here. A new classification method of fault block complex degree is put forward. The technical method of progressive exploration and development is expounded by descriptions of the structure, reservoir and traps. The Block Yong No.8, for example, were studied in detail with respect to its reservoir types, horizon calibration, reflection character analysis, structure description flow, seismic and geologic analysis, etc. The important role of coherent and attributive analyses is presented. Several working directions in the high degree exploration and development zone have been pointed out in this study. The increased progressive reserves is up to 2000×10 4 t in the play area each year.
