| Abstract: | The temporary-blocked fracturing technique is one of effective approaches to enhance the production of the low permeability reservoirs. In Pingbei Oilfield, 9 wells are used for testing the technique. The results indicate that the job success ratio is up to 100%, the effective ratio 77.8% and the total oil increase 4032t, thus achieving a good stimulation effect. The field practice shows the temporary- blocked fracturing technique provides important technical guarantee for further exploitation of Pingbei Oilfield. |
