Tired of looking at a barrage in the United States found that giant oil fields after the news, today, small make up to you and the uplifting spiritual sustenance: petrochina qinghai oilfield fifth YiDunJi gas fields will be born!God not only bless America the land, we China is also a cornucopia!
Exploration and development research institute recently, petrochina qinghai oilfield company news, qinghai oil field in the deep exploration for more than a year 5 consecutive successful drilling oil and gas equivalent of nearly one thousand tons of high yield Wells, heralding a YiDunJi reserves of oil and gas field is born again.
The west hero ridge in the western qaidam basin tectonic belt, the deep exploration in the area of 2600 square kilometers, the average depth here at about 4600 meters.An average elevation of 3200 meters of the west exploration area, the very complex geological structure, the difficulty of exploration and exploration risk is huge, has been hailed as a world class exploration problems.For 30 years, the west deep exploration never see big results.The success of the five productive Wells stopes, make the west after the north, YingDong, proposed, zaha springs, after another YiDunJi reserves of oil and gas fields.
According to qinghai oil field oil extraction factory director BaoYuan three piers, November 28, five Wells lion 205 Wells 143 days of the cumulative production of crude oil 62000 tons, 12 million cubic meters of gas, as the qinghai oil field the hero end block lion ditch deep "captured" the single well production of the highest in 30 years, the longest time, the fastest return on investment, benefit is the best production Wells.
As we know, the qinghai oil field the main areas of exploration and development in the qaidam basin as "cornucopia", is the one of the important areas of onshore oil and gas exploration.Qaidam basin is one of the seven major inland basins in China, the geographical area of about 25 square kilometers, sedimentary area of 12 square kilometers, the largest sedimentary thickness of more than 17000 kilometers.Oil more than an average elevation of 2900 meters, the oxygen content in air was only 70% of the mainland, is the domestic natural conditions and working environment is one of the most difficult fields.By the end of 2010, found 23 oil and gas fields, among them, the SeBei gas field is one of the four atmospheric zone.Has now completed "shibuya - ning - LAN" and other six gas transmission pipeline and "flower," oil pipeline, the gas is far to xining, lanzhou, yinchuan, Beijing and other cities, is for the main gas field of winter.
While the British lion 205 Wells of west exploration area is found in the west region of qinghai oil field in 2016 deployed a appraisal well, design well depth of 4600 meters.On March 8, 2016 the well drilling, drilling 1 June to 3598 m, it found that good oil and gas shows.On June 6, complete the open hole for injection production, currently use 12 mm nozzle production, oil pressure and mpa, producing about 1089 cubic meters, nissan 96438 cubic meters of natural gas.
Before this, in the west of qinghai oilfield exploration area have been "captured" the lion 1-2 38 well and well.The lion 38 Wells drilled well depth of 3804 meters, with 8 mm nozzle production, oil pressure 25 mpa, nissan 605 cubic meters of crude oil.Lion 1-2 finish well drilling depth of 3004 meters, with 20 mm nozzle production, oil pressure 13.5 million mpa, nissan 912 cubic meters of crude oil, natural gas 110000 cubic meters.
In petroleum exploration and production branch deputy general manager hai-qing he said the qinghai oil field the west has won five deep exploration oil and gas production equivalent of one thousand tons of Wells, is a group company of high yielding Wells in recent years, new tertiary oil and gas reserves of more than one hundred million tons, is very encouraging.
