Sinopec News Network reported recently that the risk pre-exploration well Yongxing 1 well recorded by the XN021 logging team of Sinopec Jingwei Southwest Observation and Control has been tested with a daily output of 111,100 cubic meters, and has gained industrial airflow
Well Yongxing 1 is a risk exploration well deployed by the Southwest Oil and Gas Company in the Mianyang slope zone in the western Sichuan region of the Sichuan Basin, focusing on exploring the gas-bearing nature of the dolomite reservoirs in the Leikoupo Formation in the Mianyang slope zone and the effectiveness of structural-stratigraphic traps
Deploy a strong team to consolidate the logging foundation
In the face of practical difficulties such as the lack of data from adjacent wells, the high safety risk factor, and the high pressure and high sulfur content, the logging project department organized a technical team in advance to carry out technical analysis, and was equipped with skilled logging technicians to be responsible for the well construction
The technicians of the logging team collected data from adjacent wells in time, thoroughly understood the geological design, formulated detailed logging quality measures, and conducted timely geological reporting and risk warnings for abnormal risks in different intervals
Experts stationed successfully to "wear a hat"
During the drilling and construction process, the company strengthened the management of logging technology, the main leaders supervised the hanging points, and the experienced technical experts were stationed on site to guide and assist the logging team to carry out logging work in a solid manner
Aiming at the task of coring on the unconformity surface of the top of the Leikoupo Formation in the design of this well, the Mud Logging Research Institute increased stratigraphic correlation work and strengthened the application of elemental logging data.
During the coring process, the geological cycle was carried out in time to accurately capture the stratigraphic boundary and drilled to a depth of 5713.
Linked consultation helps explain and evaluate
During the construction of the Yongxing 1 well, the Jingwei Processing and Interpretation Center fully mobilized the internal forces of the Jingwei and latitude, organized the experts of the Jingwei and latitude in a timely manner, and carried out the interpretation and evaluation work of the well in the form of Dingding video conferences
After entering the construction of the key interval, the Southwest Monitoring and Logging Research Institute designated a scientific research team to follow up, carry out formation comparison and analysis while drilling in a timely manner, and organize technical forces for discussion in time when difficult problems are encountered, so that they can be summarized every day and summarized every Monday
After remote consultations with experts from all over the Jingwei area, we provided the owner with recommendations for layer selection and testing.
