Study On Enhancing The Development Effect Of Low Permeable Chaoyanggou Oil Field

As limited by reservoir and well network, development effect of low permeable Chaoyanggou oil field has gone worse with the prolonging of the developing time. Based on the studies of many scholars home and abroad about the development effect, as well as the reservoir character of Chaoyanggou oil field ,this paper focuses on enhancing the development effect of low permeable Chaoyanggou oil field as follows:1. Because being clear about the character of remaining oil is the basis of choosing method to enhance the development effect, we studied the means of remaining oil description firstly, and after that, we pointed out the distribution of present remaining oil of Chaoyanggou oil field .2. Combined the static characteristic of Chaoyanggou oil field with its developing situation, we discussed the shortage of its network, and pointed out the development effect can be improved by enhancing its well density .We fixed the technique and economic limit of infilling well, as well as the well pattern. We also discussed the development effect of the infilled area, and the infill-drilling potential of different areas under different business policies.3. In this paper, we developed the study of improving the development effect of Chaoyanggou oil field with hydrodynamic method, and we study in detail the principle of periodic flooding, liquid-flow orientation changing, and injection profile modification, as well as their conditions. Some examples are put forward to prove that these techniques are useful in Chaoyanggou oil field.The knowledge offered in this paper is basic to enhance the development effect of Chaoyanggou oil field, and it also have great reference value to development of similar reservoir.
