Research and application for wellhead multi-channel pressure testing technology

Wellhead pressure testing is an important measurement of well control in oil and gas drilling, well completion, well workover and logging. It is significant for oil and gas well control management. One new pressure testing equipment was introduced in this paper. It used multiple channels of parallel test probe instead of single pipeline pressure testing in turn. It was applied in the Tahe Oil Field, and the effect under different wellhead conditions was discussed in detail.
