滩海地区地理位置特殊,钻井少,各种资料获取、采集难度大,储层横向变化大,油藏类型多样。以埕海油田为例,利用地震资料开展了大位移水平井对比,建立了地层模型和构造模型,并在地震反演数据体约束下建立了储层岩相模型,进而在岩相模型的控制下实现储层参数建模。通过三维地质模型的建立,提取了设计井的岩电测井响应特征曲线,为井位优化、现场跟踪和开发方案的优化提供了依据,最大限度地降低了产能建设过程中的风险。
Beach area special geographical location, less drilling, access to all kinds of data, acquisition difficult, horizontal reservoir changes, reservoir types and diverse. Taking the Qionghai Oilfield as an example, the seismic data were used to carry out the comparison of large displacement horizontal wells. The stratigraphic model and structural model were established, and the reservoir lithofacies model was established under the seismic inversion data body. Then, the lithofacies model control Under the reservoir parameters modeling. Through the establishment of 3D geological model, the response curve of rock well logging response of designed well is extracted, which provides basis for well location optimization, on-site tracking and optimization of development plan, and minimizes the risk in capacity construction.
