Applied Study on Fracturing Pressure Prediction

In the course of oil and gas exploration and development , we have to make fracturing treatment on formations with low porosity and permeability in order to achieve commercial oil production, or to raise per well oil yield. Fracturing treatments have great effect on the full process of oil and gas exploration and development in the oilfields, especially have effect on the oil reservoir with bottom-water in great block and thickness. If engineering pressures are not properly controlled. it is likely to make bottom - water breakthrough up into oil reservoir, and so as to make mistakes in oil - testing, and to reach false conclusions,Which would put off the discovery of oil reservoir and the appraisal of oil reserves. Utilization of well logging data for predictions of fracturing can supply data about proper increment of pumping pressure, and reference data of formation fracture pressure to optimize fracturing treatment. Following this procedure fracturing treatment not only can make the oil production increase , but also can avoid bottom - water breakthrough up into the oil reservoir so that high and stable oil production can be obtained.In the same time, influences on fracturing treatment are analyzed in the paper.
