At last, bitpressure control arithmetic based on fuzzy theory is compiled.
最后完成了对于钻压模糊控制算法软件的编制。

The laying position and well blowout pressure are analyzed and discussed briefly and the relationship curve of drill bitpressure drop vs flowrate and fluid density i.
对其安放位置及井喷压力进行了简要分析和探讨,建立了钻头压降与流量、流体密度的关系曲线。
