China Petroleum Network News entered in October, the Western Tibetan plateau heating season. The three largest gas fields in Qinghai oilfield are in the small peak of the first round of production this year, and the daily production of natural gas has reached 16 million 500 thousand cubic meters during the small and long holidays, an increase of 1 million cubic meters over the same period of last year. This is a sign that the natural gas production and marketing of Qinghai oil field has entered the mode of providing for the whole market in winter.
According to the oil production operation Department estimates, up to 6 months of natural gas supply in the winter and spring period, Seninglan, Yinchuan, Lhasa and the surrounding gas downstream market demand in 3 billion cubic meters. To better protect the normal supply of Gansu and Qinghai, Tibet, Nanjing four provinces users of natural gas resources, Qinghai oilfield developed 4 sets of production supply scheme, inverted monthly gas production plan, production of refined to the wellhead, a reasonable allocation of the contradiction between supply and demand, to meet the market needs of users, a good social responsibility.
In order to ensure the safe and stable control of natural gas supply and demand during the winter and next spring, the oil field uses the three gas fields during the summer and autumn production period, and comprehensively examines the key equipment, process flow and gas pipeline of the gathering and transportation station". According to the ice blocking well control scheme, the downhole throttling technology is carried out, and the measures such as low temperature foam drainage gas recovery technology, centralized pressurization gas lift and inter well interconnection gas lift are carried out to ensure the normal production of gas wells in winter. According to single well data, different production strategies are formulated for different types of gas wells.
Implementing balanced gas production. To strengthen the management and optimization of single well gas switch and a number of initiatives, effectively control the natural decline, to ensure the end of the year old wells Nissan 14 million cubic meters of production capacity in the end; optimization measures work arrangements, measures of increasing gas reached 2 million cubic meters of natural gas resources to effectively break the bottleneck of insufficient.
Speed up the pace of production and construction, to ensure that the production and construction in place rate of 100%, Nii productivity contribution rate of 24.5%. Production capacity of 500 million cubic meters, 87 wells will all stop production at the end of October, before the end of the new Nissan 1 million 970 thousand cubic meters.
