According to the China Petroleum Daily, since the beginning of the year, the Lukqin Oilfield of Tuha Oilfield Company has been able to achieve 210,000 tons of crude oil production throughout the year by strengthening its production organization and testing and applying new technologies. The Ruqin Oilfield belongs to the ultra-deep heavy oilfield of world-class development problems. In the course of the development of Luqin Oilfield, Tuha Oilfield Company actively tested and applied new technologies, successively carried out natural gas throughput, conventional waterflood development, effective production of water injection and stimulation, chemical throughput increase in medium and high water-cut period, dilution and viscosity sticking in wellbore pump Rod pump lifting and fracturing, sand control and a series of special studies, formed with independent intellectual property rights of ultra-deep heavy oil development characteristics of technology and the main technology series. Among them, the use of conventional water injection technology to see the obvious effect. The proportion of effective injection wells in Tuha oilfield increased from 32% in 2008 to 50% in 2009, while the natural decline rate dropped 4% from 2008. The daily output of new wells in stratified development blocks reached 7.5 tons, and the oil recovery rate increased 0.2% or more, water flooding effect improved significantly. Based on the single well test of natural gas in the West Zone, the large-scale promotion of natural gas throughput technology in the Lukqin Oilfield was realized. The implementation plan of natural gas throughput in the Central Area was formulated. It is estimated that single well will increase 4 tons daily. While experimenting with new technologies, the Ruqqin Oil Production Plant intensified its production organization. During the year, it completed 6 new wells and 6 injection wells and 20 wells for well stimulation. In addition, they implemented well stimulation measures such as well stimulation Profile control 4 wells. The proportion of under-injection wells decreased from 24% at the beginning of the year to 9%, and the effective injection rate increased to above 86%, effectively solving the outstanding problems of contradiction between plane and section. At present, the well pattern of injection and production in Tuha Oilfield tends to be reasonable, the contradiction between water well sections is obviously improved, and the utilization rate of sections is increased by 5%. The scale of oilfield water injection is gradually expanding. Since the beginning of this year, Twelve new effective wells have been added in Tuha Oilfield, 25 of which are effective. The accumulated production capacity increased by 20 tons day by day. The natural decline rate of oilfield slowed down obviously. The output of heavy oil reached 197,300 tons.
