China oil network news reporter learned from Daqing oilfield, oil exploration system since the beginning of this year, Daqing vigorously implement the efficient exploration and fine exploration and risk exploration, obtained gratifying results were key target areas.
Change ideas, and actively seek new discoveries and benefits available reserves. Since the beginning of this year, Daqing oilfield exploration system highlight the mature region of conventional oil, vigorously develop the deep natural gas, tight oil steadily, and to strengthen Hailar Shu periphery, actively explore new areas, through changing the idea of exploration, realistically geological research, strengthen production and operation, a new concept of stimulation and other effective measures, and promote the efficiency of the exploration, fine and risk exploration. At present, 95.9% of the annual plans, 87.5% and 67.7% of the annual plans are respectively submitted for the prediction of oil reserves, control reserves and proved reserves, and the achievements in key fields of oil and gas exploration are outstanding.
Meticulous work, rich achievements in oil exploration in the middle and shallow layers. According to the "outstanding conventional oil exploration, strengthen the multi-layer stereoscopic exploration, evaluation of rolling East, the implementation of efficiency reserves; orderly tight oil, expand three Zhaoqing, deployment strategy selection can upgrade resources", to carry out a large number of detailed work of oil exploration system in Daqing, Longxi conventional oil to achieve breakthrough from the first half of this year, oil test 11 wells received industrial oil flow wells success rate of 100%, of which 56, tower 52, dragon dragon 60 wells in Putaohua and tower 48, tower 86, tower 49 wells of Saertu oil pressure at Nissan 30 cubic meters to 50 cubic meters of industrial oil flow; expand the Longxi "river line north" and the west slope of Qijia gulong, wells were deployed over a hundred million tons of high yield, formation of exploration scene.
New progress has been made in deep gas exploration. The first half of this year, Daqing Xujiaweizi depression Shahe sub group of glutenite deployment drilled 4 wells, deep wells 22H for Nissan 82 thousand cubic meters of industrial gas, deep 24, deep well 28 showed gas containing large section; preferably two wells two wells in Xushen 46H test. Wells Nissan gas from 87 thousand cubic meters to 201 thousand cubic meters, deep well 21HC Nissan gas from 42 thousand cubic meters to 123 thousand cubic meters.
