stepped-up infill drilling

It is not only proved by the concrete practice of production that infill drilling is a actual step in the development of Ansai Oil Field, but also analyzed in terms of theory that the step is correct.

通过生产实践证明加密钻井是安塞油田开发过程中的一种有效措施，并从理论上分析了它的科学性，提出了设计加密井的指导性方针，即在加密钻井前应先进行注采动态分析，认清油藏特征，才能做好加密钻井的工程设计。

The construction character, the selection of drilling equipment, drilling technology, drilling mud technology and well completion for infill drilling of thick oil well are presented with drilling cases introduce

结合钻井工程实际，介绍了稠油加密钻井工程施工的特点、钻井设备选择、钻进工艺、泥浆工艺与完井工艺等。
