Chinese oil network news reporter was informed that in November 6th, with Ansai, Jingbian, Gansu old wells tapping the potential of oil and gas field evaluation work in full swing, Changqing Oilfield to "bring old maximum potential, 50 million tons of stable power" as the goal of the "million wells evaluated project has already started.
As Changqing Oilfield is a typical low permeability, low pressure, low abundance "three low" reservoir, the date of production is the time of production, become Changqing Oilfield has been unable to get rid of the problem. Especially with the exploitation of time, Changqing Oilfield is currently more than 80% wells have entered the aging stage, the old energy shortage, decreasing speed, water cut rising, set of serious problems such as the large area appear broken. Stable production can solve the problem, become the key of Changqing Oilfield 50 million tons of long-term stable production.
To this end, Changqing Oilfield according to the development situation, based on the investigation of the implementation of oil and one block of a block, a layer of a layer, a well in a well, decided to use 3 years to review 10 thousand wells, 3000 wells were at least annually more than 1000 wells above. Based on the review of old wells and take corresponding measures, an annual increase of more than 200 thousand tons of crude oil production.
In order to ensure the realization of the goals of the old, Changqing Oilfield in the establishment of "million wells evaluated project group on the basis of the Research Institute of exploration and development of oil and Gas Technology Research Institute and the national related units also developed a" million wells evaluated the project implementation plan "and" long stop wells tapping the potential of new governance the technique scheme ", to ensure that the old units responsible for implementation scheme, results analysis.
As an important part of the stable production project of 50 million tons per year in Changqing Oilfield, "evaluation and tapping potential of ten thousand wells" has important long-term significance. Changqing Oilfield million wells evaluated project group to have up to three aspects of measures to ensure that adhere to, through various communication and coordination, further refinement of the preparation of the overall implementation of the program, do the engineering and geological combination, the project team and the production plant combination, logging evaluation and production engineering, to ensure effective implementation; adhere to the combination of the scene the entire project, from the optimization of single well scheme, optimization of construction team, earnestly carry out the important nodes and key aspects of the implementation of the scene to promote the implementation of the work; to carry out the measures and effect evaluation results, make the new layer increase reservoir built production and old layer review work to enhance the efficiency of management work carried out for Changqing Oilfield 50 million tons of oil equivalent years of sustained yield, lowering the efficiency of contribution.
