Chinese oil network news August 6th, seven Geological Brigade of Daqing oil factory vice captain Sun Jianguo told reporters that the factory's "top control, source control effect, 67 wells after fracturing increased 1 tons of oil is more than 59, the effective rate of 88.1% measures.
With the continuous development of oil fields, the cost reduction has become a major problem in stabilizing oil production. As the leader of oil field development, the Geological Brigade of seven oil production plant is designed and produced by them. In order to spend money on the edge of the knife, so that inputs in exchange for actual results, the Geological Brigade technical personnel put forward the "top control, source governance" new way, and provoked the reduction of the effectiveness of this beam.
Active measures -- plugging up from the source. The brigade of geological technical personnel to seriously analyze the whole process of oilfield development, combing the existing waste, found that the plant has entered high water cut development period, some blocks inefficient ineffective circulation is serious, not only increases the cost of development, but also not conducive to the effective use of oil, reduce the development efficiency. According to their inefficient cyclic block developed machine blocking scheme, parameter adjustment of production machines, the cumulative reduction of invalid liquid production of 13 thousand and 900 tons, the implementation cycle adjustment of 70 wells, 124 wells adjustment scheme, the cumulative reduction of invalid injection of 82 thousand and 400 cubic meters, achieved initial results in inefficient circulation management.
Offensive measures -- benefit optimization. The so-called offensive measures, that is, fracturing, it is an important means of oil production. In order to maximize the ratio of input and output, to achieve optimal efficiency, the geological team of technical staff to take "group" research mode, analysis by the engineering geological brigade, brigade and three joint wells in the oil field, by looking at the output, see, see, see the thickness of history, see the "five connected" analysis method. Do fine well selection, advanced training, optimization process, character design, the equivalent of a well fracturing before each have done a full wells CT". Up to now, a total of 142 fracturing schemes have been worked out, 102 have been implemented, and 10 thousand and 600 tons of oil have been accumulated.
Management measures - site supervision, all-round. The geological program has been perfect and will eventually be put into practice. In order to ensure that each can perform perfectly, the Geological Brigade technicians proposed the "three no" principle, as a "black faced", namely the implementation of the program do not discount, unreasonable, supervision and inspection guidance not to mind taking the trouble. In the field supervision, from the original monthly spot checks, quarterly census into random random checks. Change the past in the process of supervision, production teams focus on early assault preparations, do not pay attention to the daily management of the actual situation, from the previous "search results" now become "process", through the transformation of this mode of operation to promote the management level to further upgrade. Through irregular supervision and inspection, the total data rate of injection wells has increased from 95.7% to 96.7%.
