Changqing Oilfield builds the largest tight oil experimental area in China
Chinese Petroleum News: August 4th the reporter was informed that, as of now, Ordos basin Changqing Oilfield 7 dense reservoir since 2012 cumulative production exceeded 2 million tons, reaching 2 million 387 thousand tons, become the test area of the largest dense oil development.
The large amount of tight oil resources in Ordos Basin is an important support for the stable production of 50 million tons in Changqing Oilfield, but it is difficult to develop. In order to explore the effective tight oil development technology, 2011, to co-ordinate the deployment in the group, the shares of the company, in accordance with the general idea of "clear resources, preparation technology, key breakthrough, steady progress, tight oil and actively carry out research trials in Changqing oilfield. After the initial evaluation, exploration technology, innovation and upgrade and expand the test in four stages, the long horizontal wells, horizontal well optimization volume fracturing, the key technology breakthroughs have opened up three tight oil exploration and development zone.
In the development test, the breakthrough of key technologies in Changqing Oilfield has found a "sweet" for tight oil development". The innovation research of optimizing pattern wells long level, to overcome the tight oil lithology, physical property and oil bearing changes quickly, large differences, strong heterogeneity, low drilling rate bottleneck and fracturing perforating optimization difficult, independent technology to achieve the volume of long horizontal well fracturing, hydraulic sandblasting, fast development drilling composite bridge plug, positioning Sleeve Tee, EM series of fracturing fluid and other key fracturing tools and materials, the formation of annular hydraulic sand blasting sand fracturing and drilling speed of composite bridge plug fracturing, casing fracturing, the whole process of positioning the ball seat and sand slick water fracturing fluid 4 sets of main technology. At the same time, we creatively put forward the quasi natural energy development technology for the initial horizontal well, volume fracturing, no flowback, and supplementary formation energy.
