A prosperous career must have unwavering and firm convictions. From the young test freshman to the experienced test director, from "Xiaobai" to "civilian and military" experts. For more than ten years, he has been careful and thorough in small matters, treating every well as his own work.

At present, he and his team members have won 6 national utility model patents and 8 scientific and technological progress awards of Tianjin Branch of Co., Ltd., and he is Zhang Xinghua, the test director of the exploratory well project group of the Engineering Technology Operation Center of Tianjin Branch of Co., Ltd.

The clock has passed 4 o'clock in the morning, and through the porthole glass in the living area, you can see Zhang Xinghua shuttle between the data acquisition room, the measuring tank and the separator. It wasn't until Dongfang showed a white belly, and an imperceptible smile climbed onto Zhang Xinghua's tired face.

A few days later, the roar of the five fracturing pumps stopped abruptly, and the Bozhong 26-5 structure successfully completed the main fracturing operation of the pre-exploration well test. This is the first time that the Bohai Oilfield has carried out exploratory well fracturing on the platform, and the amount of sand added has created the highest sand addition scale in a single-layer fracturing operation in an offshore oil field in my country.

As the site commander of this large-scale operation, Zhang Xinghua led the team to overcome numerous difficulties and ensure the high-quality completion of target tasks. He said: "If the test operation is the "one step" in the entire oil and gas exploration process, then the control of the footwork is the basic skill that every tester must practice hard."

In 2013, the first multi-element thermal fluid test well in Bohai Oilfield was settled in Luda 5-2 North Oilfield. If this test goes smoothly, it will provide new technical means for the verification and release of Bohai heavy oil reserves. As soon as the injection operation started, Zhang Xinghua began the encryption inspection. During the operation, he keenly discovered that the wellhead casing was lifted by at least 4 cm in one hour. Once the wellhead lift exceeds the pipeline's tolerance, it may bring major risks to oil and gas production. Zhang Xinghua didn't dare to neglect, immediately convened everyone to brainstorm the research plan, and finally ensured the smooth implementation of follow-up work through process transformation and "stepped" heat injection method.

Zhang Xinghua said: "Every operation is like a battle. There is no victorious general, but as long as we control the details, we can minimize the chance of failure." In his opinion, Bohai Oilfield does not lack a stage, let alone a stage. In the absence of opportunities, if you want to succeed, it depends on whether you have a unique job to defeat the enemy when the challenge comes. And his unique job is to be a little more delicate than others.

In 2018, during the test of Well 5 in the Bozhong 19-6 gas field, Zhang Xinghua kept a close eye on the test data-production curve and said nothing. After 15 minutes, he found that there was a slight difference between the actual pressure and production curve and the expectation. At the same time, although the fixed nozzle that was switched during the well cleaning was normal in size, the cross section was slightly different. Although these errors are only a few centimeters, the oil well test can't make any mistakes.

After years of experience, the oil spirit of "three old and four strict" and "hard work" is deeply rooted in the hearts of the vast numbers of oil workers. Once again, with a pair of "hot eyes" and an attitude of never letting go of any detail, Zhang Xinghua eliminated the hidden danger of the accident in its infancy. He has been upholding the test process as if he was polishing a handicraft, he must continue to sculpt and refine to achieve perfection, and every well he participated in the operation tried to become a "exquisite work."
