  China Petroleum network news, September 3rd, lion 204 well ahead of schedule a week into production. It is understood that this year in Qinghai oil field is the most complicated geological structure, Qaidam Basin area of 4 deployed es were lateral drilling sidetracking success. The 3 wells that were put into operation in August accumulated more than 2000 tons of crude oil.

  ES is currently the world's highest oil production area, but also the Qinghai oilfield in 13th Five-Year during the completion of the main battlefield of the scale of tens of millions of tons of oil and gas fields in the plateau.

  Ground ravines, underground high temperature and high pressure, crack, salt plugging, buried depth is an tectonic feature". Before 1990s three three es no harvest". In recent years, with the advances in exploration technology, Qinghai oilfield successfully broke through the bottleneck of exploration of deep salt and salt es, the formation of a new exploration theory. In the new theory and new technology, 3 years of continuous exploration in an area by nearly 10 over a hundred tons of production wells, showing good prospects for exploration.

  Because of the complex geological conditions caused by a part of Spanish, producing wells, short life cycle, put into operation soon to production; part of a well work of recovering the production cost is high, is not worthwhile. In order to let the verge of "paralysis" wells theprocessofrejuvenation, Qinghai oilfield this year in the British West Block optimization has the potential of 11 wells, using the original borehole sidetracking exploration. The purpose is to further understand the distribution of geological structure, recover the production of blocks, and deepen the geological understanding of transverse and vertical blocks.

  Since the well 35 has been out of salt and formation pollution, it has failed to achieve the desired exploration purpose. In March this year, the success in the old well sidetracking, the initial liquid yield up to more than 100 cubic meters in July, according to the formal system of oil production, production stable at 7 tons.

  An average depth of drilling at 4500 meters. Drilling a well takes about 100 days, and drilling costs are high. Sidetracking wells exploration in the eye, each well can save 1/3 pure drilling time and drilling cost decreased by 30%, an increase of 20 days of construction production speed, increase production effect highlights. Shi 42 well in the 3499 meters side drill, a windfall in the E32 layer, the discovery of new horizons, the middle test production, Nissan 43 tons of crude oil, further demonstrates the great potential for deep exploration in the es.

  Oil exploration department of petroleum exploration project manager Luo Yong said, "revitalize the old borehole for complex es exploration speed, the development of production, production cost, and explore a new way.
