The Fine Geology Study And Method Of Augmented Injection Of Fang 707 Block

Contrasting and dividing the oil reservoir correctly is very important to the study of reservoir's construction, microfaces, state and heterogerneity . In order to describe the geometric construction, dimension and continuity the sandimentation unit must be divided in detail which makes the contrasting very important especially during the period of development. When the oil field goes into high water period from original state the reservoir changed and the reservoir must be described. Knowing the distribution of remaining oil and adopting the correct measure the aim of controlling water and oil can be arrived. Further more the ascending of water cut velocity can be decreased. In this paper the microfacies of putaohua layer in the fang-707 block of song fang tun are studied in detail on the bases of drilling, well logging data. The cause of formation and geology model are built as well. Combining the data of sop, liquid profile and dynamic development the distribution of remaining oil is forecasted in this block. The effect of acidizing and fracturing is analyzed and the results on the different layers and polluted condition are analyzed as well. According to this study the method of increasing oil production and water quantity is given in this block.
