China Petroleum network news, as of August 14th, Changqing oilfield production plant two completed oil and water measures 272 wells, oil breakthrough 20 thousand tons. Since the beginning of this year, two production plants to make full use of the application of mature technology, continuous optimization measures of fine structure, well and layer selection and optimization measures of technology, active around the low horizontal wells governance and repeated modification technology test, to carry out the work measures.
In the work of oil and water wells, oil two plants from the "fine selection of wells and layers, preferably for process, optimization of process parameters and the optimization measures to carry out horizontal well structure, governance, to carry out horizontal wells refractured test, the implementation of the overall profile" in 7 aspects, under the premise of ensuring the effect and benefit, to small detonation pressure and acidification of low cost, fast track measures. The fracturing methods of the fractured wells are mainly based on acidizing and reduce the number of fracturing wells. In addition to the key process tests, large-scale fracturing measures such as large displacement and large amount of sand are strictly controlled to reduce the input cost.
In the organization of production, two production plants and special vehicle transport company timely communication, to ensure that all types of special vehicles with the place; and collect the production information, increasing oil project group coordination to solve the problem and measures to improve operation efficiency of production organization. At present, the average single well period of two oil production plants is 13.21 days, 1.29 days shorter than the 14.5 day plan period.
