Eastern geophysical exploration "two wide and one high" precise exploration of Junggar Basin
According to China Petroleum Network(correspondent Zhu Zhanjun),"a revolution is quietly unfolding for Xinjiang geophysical Office of Oriental geophysical exploration,which has been engaged in petroleum seismic exploration for more than 60 years in Junggar basin.This is the"geophysical tool"called by Kuang Jun,deputy general manager of Xinjiang Oilfield Company.This"tool"refers to the"two wide and one high"seismic exploration technology in Junggar basin Successful promotion and application."On December 24,Huang Yongping,chief engineer of Xinjiang geophysical exploration office,said.
In recent years,Dongfang geophysical continues to increase the test and promotion application of its own brand geophysical equipment and"two wide and one high"seismic exploration technology,and has successively obtained a series of successful cases in Junggar basin,with significant improvement in data quality and full recognition of Xinjiang Oilfield Company.
Es109,a national major landmark achievement,has successfully carried out field test in xiquan-1 well of Junggar basin,and has been put into production in huobei-2 well.The system stability meets the requirements of seismic exploration and fills the domestic blank.
The high-density vibroseis high-efficiency acquisition sliding scanning technology test was successfully carried out in the south of baijia-1 well by the eastern geophysical research project.It was rapidly popularized and applied in cai9 well area and maxi-1 well area in the same year,which realized the project establishment,implementation and popularization and application in the same year,and provided an important technical guarantee for promoting the deployment of the second three-dimensional earthquake in Junggar basin.
Dongfang geophysical exploration also successfully completed the field test of two-dimensional acquisition of hawk node instrument in the northwest margin,which accumulated experience for the promotion and application of self-developed equipment and sharp tools.At the same time,the field test of 60000 g3i instruments has been completed in well block ma131,and the software and hardware equipment and supporting technologies independently developed by Dongfang geophysical exploration have been used in the test,achieving three breakthroughs.It is the first time in China that"g3i instrument+low frequency vibrator+digital seismic team"is used in the three-dimensional project of Dinan 8 well area.
The popularization and application of"two wide and one high"seismic exploration technology has continuously improved the efficiency of seismic acquisition and data quality in Junggar basin,forming a virtuous cycle of great progress in geophysical exploration technology and great discovery of oil fields.
