Daqing celebrates Changqing

China Petroleum News (Reporter Wu Xiayan, Zhang Yunpu, Yang Wenli) In the first five months of this year, Daqing Oil Field gave full play to the role of science and technology as the primary productive force, producing 16.74 million tons of crude oil, and won the initiative to stabilize production of 40 million tons of crude oil for the ninth year. The beginning of a steady and stable production lays a solid foundation.

By the end of 2010, the comprehensive water content of the main oil fields in Daqing Oilfield was as high as over 92%, making it more difficult to stabilize production and facing severe challenges to sustainable development. Limited resources, unlimited technology. The Daqing Oilfield, which shoulders the burden of 40 million tons of crude oil, continues to rely on scientific and technological progress to climb to a higher goal.

Since the beginning of this year, Daqing Oilfield has made breakthroughs in oil exploration and gas search theory and supporting technologies in the “low, deep, and difficult” fields, and has vigorously tackled the “four key technologies” of earthquakes, drilling, fracturing, and reservoir evaluation. We are fully prepared for the "recently secured production" and "going out in the medium term and sustainable in the long term." In the first quarter, the production of oil from water flooding in Daqing Oilfield was 170,000 tons higher than the operating plan, which was the highest in history.

In addition, with the production of 17.2919 million tons of oil and gas equivalent in the first five months of this year, Changqing Oilfield stands steadily at the commanding height of 40 million tons of oil and gas equivalent per year.

On June 8, the reporter saw from the Changqing Oilfield Production Statement that in the first five months of this year, 8.366 million tons of crude oil and 11.24 billion cubic meters of natural gas were produced, an increase of 22.46% and 20.6% year-on-year. At this rate, Changqing Oilfield will not only be able to achieve a 40 million-tonne oil-equivalent hard leap this year for the first time, but will also contribute a medium-sized oil and gas field to the country.

Since the beginning of this year, tens of thousands of exploration, development, and engineering and technical personnel of Changqing Oil Field have conducted in-depth on-site research and follow-up services, and actively promoted hydraulic sandblasting on the basis of measures such as water injection and acidification for old oil and gas reservoirs. Splitting process technology. After the implementation of the horizontal well remodeling process in the Sulige gas field, the average unobstructed flow has greatly increased. Among them, the highest unqualified flow rate for single well test was 1,134,900 cubic meters per day, and the average production per day of wells that had been put into production was 69,900 cubic meters, which was more than four times higher than that of the vertical well in the Sulige gas field.
