摘要
胜科1井是中石化股份公司一口重点科学探索井,能否顺利实施将会影响到对东营凹陷深层油气藏的认识和勘探进程。该井钻探层位深、地层变化大,钻前异常地层压力预测尤为重要。在地震地质综合研究的基础上,确定了本区地层压力的概念模型,分析了地震速度与地层压力的关系,有效地提取了地震速度并正确地估算了上覆岩层压力。预测结果与开钻后的测试结果吻合较好。
Shengke-1 Well is a key well for scientific probe of Sinopec, and its proper implementation or not is related to the understanding of deep reservoirs and prospecting courses in Dongying sag. This well is characterized by deep drilling horizon and varied formation lithology, so its predrilling prediction of abnormal pressure is the most significant. This paper presents the conceptual model for the formation pressure in this area based on the seismic-geology researched results. By analysis of the seismic velocity vs. the formation pressure, the seismic velocity is effectively picked up, and overlying formaiton pressure is properly estimated. The predicted result is well comparable to the testing result.
