【Summary】:

On December 10, with the completion of the fracturing of Well Wei 305-side 19, the 4 inch casing in the side drilling of Zhongyuan Oilfield was sealed with a mechanical packer and the two-layer fracturing test was successful. In recent years, the lateral drilling of 4-inch casing suspended in 5-1 / 2-inch casing in Zhongyuan Oilfield has been increasing year by year, and the demand for fine-grained and fractured lateral drilling is increasingly urgent. To this end, Zhongyuan Petroleum Engineering Underground Special Operations Company organized technical personnel to actively carry out project research. Through 8 years of research, testing and improvement, the technology of 4 inch casing sealing and splitting and splitting pipe string gradually matures. Stability and safety meet design
