January 8, 2020 is an ordinary day in the long river of history, but it is an extraordinary day for us Ruichi people, because today the first station of the Yongshao Jinqu station restructuring project-DN610 non-stop transmission and opening level under pressure The first drilling was successfully completed. It laid a solid foundation for future hole-opening projects and also made a good start for a firm foothold in the refinery.

Let the time go back to one day in March 2018. The first station pressurized plugging and rerouting project will start. The leaders of various departments and installations in the refinery plant are not familiar with and unfamiliar with the pressurized tapping operation. They are not familiar with our process flow. Vague, the theory is more than the actual objects. The most important thing is that this pipeline is the main artery of the entire Zhenhai Refinery. In the event of an unexpected shutdown, the entire refinery will have to stop. One can imagine the pressure of the departmental device leaders. Suddenly, they questioned the continuous transmission and tapping operation under pressure. There were countless meetings and discussions, but it was impossible to determine whether it was feasible. After multi-party communication with the leaders of various departments and devices, the industry was invited In-house experts conducted expert argumentation and special plan review, confirming the operability, feasibility and reliability of various emergency plans of our plan.

The passage of the plan is the beginning of the construction. There are still many examination points behind. Note that, for example, the concrete road is broken and excavated. It is beside the Sanchang installation. Whether there are pipes and cables underneath, it is impossible to confirm on site. Manual excavation is basically eliminated. It is necessary to adopt the method of "excavator excavation and manual cooperation". The leaders of refining and chemical industry also attach great importance to it and repeatedly explain to us, safety first, slow digging, shallow digging, and every shovel of the excavator goes down to ours. My heart is tugging, every time the shovel goes down, I am terrified, for fear of digging out any "treasures". We are really walking on thin ice. The full outline of the work pit has finally emerged. There are 3 pipelines near the work pipeline. Under our careful operation, The whole picture was revealed unscathed. The time is approaching the Spring Festival. The construction tasks are heavy and the work pace is intense. The daily work schedule does not allow us to rest. The pipeline already has the conditions for welding tee, but I have to say Zhenhai Refining & Chemical Co., Ltd. The water resources in this place are really "sufficient". The water in the work pit was pumped out the day before, and when I went to prepare for welding the next day, the water actually flooded the welding pipeline. At this time, Manager Liu first thought of pumping water with a diaphragm pump. Electricity, the device has a gas source and can be pumped 24 hours a day, which completely solves this problem, including the later operation. The day of the opening in a blink of an eye is also the most critical day. The biggest risk is whether the falling pieces of the drilling can be taken out. , We also thought of many ways, for example, increase the number of snap rings, reduce the vibration of the opening, and test each snap ring to see if the snap ring is effective. In this opening operation, Comrade Guo Qingjun was very calm. Only with confidence can he be calm and composed, and guard the hole-opening machine every step of the way. Until the moment the film was taken out, his face didn't seem to be serious anymore, and there was a smile on his face. The leaders of the refining plant's opening headquarters also breathed a sigh of relief, showed a satisfied smile, and cast approving eyes.

As a key project of Zhenhai Refining & Chemical Corporation, Sinopec Group Company will come to Zhenhai Refining & Chemical Corporation to carry out "Four Nos and Two Directs" work inspection. The inspection team will come to inspect the work. The leader of Zhenhai Refining and Chemical Company Mo came to the site to make specific arrangements for some on-site issues. In particular, the non-stop transmission and pressure tapping headquarters was established, and the headquarters was set up at the tapping site. The handling of some work tickets and passes required on site provided great convenience. The leaders of various facilities and departments of Zhenhai Refining & Chemical Co., Ltd. implemented the "ten regulations" operation requirements, and the leaders of major risk operation sites led shifts and participated in the entire operation process. Today, the inspection team of Sinopec Group came to our drilling site and conducted a comprehensive inspection of the hazard identification and analysis of high-risk operations, the implementation of measures in the emergency plan, the implementation of safety technology, the improvement of work permit tickets, the inspection of tools and tools, and log records. , Also put forward valuable opinions.

The first horizontal drilling operation was successfully completed, and it also provided a reference for the non-stop drilling operation under special conditions in the future. It is indeed a happy event that deserves encouragement.
