The amazing oil sculpture in the Shanghai World Expo Oil Museum is made of high-condensation oil produced in Liaohe Oilfield. The situation of production of high-condensation oil in Liaohe Oilfield was a pleasant surprise. In the first 7 months of this year, the daily output of high-condensation oil was running above the 2,548-ton plan line. The over-production exceeded 10,000 tons, and the initiative for the “one-million-ton scale†target was in full swing. Liaohe Petroleum people are in control.
Liaohe Oilfield has 300 million tons of high-condensation oil geological reserves, has used 240 million tons, is China's largest high-condensation oil production base. Liaohe Oilfield high-condensing oil is characterized by high condensation point, high wax content, low sulfur, and low colloidality. The maximum freezing point of crude oil is 67 degrees Celsius, and the lowest is 37 degrees Celsius, and it shows a solid state at room temperature.
Faced with the contradictions and difficulties in the exploration and development of high-condensate oil, this year, Liaohe Oilfield put forward the goal of “guaranteeing a scale of 1 million tons and build an efficient oilfield developmentâ€, and implemented “to increase the contribution rate of science and technology as a means to firmly grasp high coagulation. Exploration and Development Measures for the Production of 'Bull Nose' by Single Wells.
In view of the strong heterogeneity of multi-layered sandstones, the long-term water-cooling damage in high-condensing reservoirs, and the difficulty in controlling dual-media development in buried-hill reservoirs, scientific and technical personnel conducted research on key issues to form a high-reservoir oil reservoir to enhance oil recovery. The core technology, and the promotion and application of industrialization, has increased the production efficiency of single wells. Shen 95 block water and cold damage seriously, water drive development effect is poor. In response to this, the Liaohe Oilfield launched an electromagnetic heating test to significantly reduce the injection pressure, and the well group cumulatively increased 1801 tons of crude oil.
The study on the suitability of water injection and water injection standards in Liaohe Oilfield has achieved the goal of “injection of good water, sufficient water injection, and fine injection of waterâ€, and the yield of single wells has increased steadily. Liaohe Oilfield carried out technical research on increasing oil and low-cost oil production in major blocks, promoted high-condensate oil cold recovery technologies, effectively reduced mining energy consumption, and proposed that the scale of cold recovery this year reached 80 wells.
In the high-condensate production operation area, single well management was used as the basis for increasing production, finely controlling well lying, and each well was provided with treatment and nursing measures, effectively reducing the lying rate of the 9 blocks. At the same time, through the daily maintenance of fine oil wells and fine oil well measures to tap potential, the production rate of oil wells is continuously increasing.
