Henan oilfield peripheral basin of oil and gas exploration DuoNian 30 attack means of the funk of the long end is broken
The National Day eve from henan oilfield proud: deployed in luoyang basin-how the tuen well fracturing implementation 1 homework, was awarded the industrial air, September 27, started with 10 mm nozzle choke, nissan gas to present stable in 6600-7200 cubic meters. This suggests that luoyang basin exploration-how have made important breakthrough, and also marks the henan oilfield peripheral basin of oil and gas exploration DuoNian 30 attack means of the funk of the long end is broken.
Luoyang basin in henan province is located in the Midwest-core, an area of about 3000 square kilometers, according to the latest research achievements calculation, 460 million tons of resources in the Triassic (of oil equivalent). Since the late 1950 s, coal exploration department for coal is given priority to, in luoyang basin-how did a lot of regional geological survey. Since 1977, henan oilfield to search for oil and gas in the region for the purpose, began to deploy 2 d seismic exploration. At the end of the 1970 s, deployment los 1 well drilling and well, but two los because the formation oil &gas showing low level, the technology at the time limitations, exploration, no success. In 1997, the former China petroleum and natural gas corporation in the deployment of the new department of Iraq well drilling 1, although see oil &gas showing, but by the exploration of bondage, exploration and know no substantive progress. Since 2009, the company began to pay attention to and increase the strength of unconventional oil and gas exploration, henan oilfield according to unconventional idea for oil and gas exploration henan oilfield peripheral each basin, evaluation, through our selection of various exploration achievement data analysis, thought the analogy luoyang-core basin and ordos basin, which in the oil and gas accumulation conditions has some similarities. And all these years due to the progress of science and technology of the ordos basin, has formed a very big oil and gas exploration and development of the scene. Luoyang basin-how the Triassic buried moderate, distribution area wide, with large area of oil and gas geologic conditions. Henan oilfield luoyang basin-how the oil and gas exploration in the Triassic as main object, the deployment of drilling in tuen mun well. 1
1 the well this year in tuen on April 4 spud, June 9 completion, well depth of 2100 meters. In the process, the well logging in the 635 m to 824 m for oil and gas well see that layer 4 11 m, in the 635 m ~ 1882 m for natural gas abnormal test well see 26 floors 145.3 meters. August 11, 1874 meters at tuen mun well 1 ~ 1884 m by the strata small test, convert the highest nissan fracturing of 4192 cubic meters of natural gas. Thoroughly understanding for luoyang-how the exploration potential, and Triassic basin on 23 September, fracturing improvement construction, industrial YouQiLiu eventually won, and display of luoyang basin-how good oil and gas exploration prospects.
Henan oilfield exploration division director LvMingJiu points out, this is the 1994 in xinjiang yanqi basin made exploration break, henan oilfield again in a new basin made substantial progress of oil and gas exploration and breakthrough. This opens up the henan oilfield, the new field of oil and gas exploration, the new world, for henan oilfield for the harmonious development of effective to have the important meaning.
