Remaining Oil Distribution And Exploitation Technology Research For BQ10 Block In Gu Cheng Oil Field

BQ10 block is selected as a researching aim. After producing for 21 years, the inspissated pool has got into later stage of steam huff and puff. With the cycle outcome and production factor decreasing, the remaining oil distribution is getting more and more complex. It is needed to get reservoir description and research on remaining oil distribution to find out the direction to exploitation. Based on the research and proofs, it is also needed to provide reasonable technical solutions for raising recovery ratio. The geological, logging, producing data are used in reservoir description and research on remaining oil distribution. After modeling precisely and making definite of remaining oil distribution, draw up reasonable exploitation scheme to enhance effect of development.After descripting the reservoir comprehensivly and making structure model and property model using Petrel, make history match using CMG which can deal with well in corner or on edge thus ensure choice of simulation area and handling with edge. After all the exploitation scheme is draw for enhancing development.The reserve volume is calculated with Petrel showing the matching accuracy degree is so high that the error is less than 2.46%. It is demonstrated that the geological model could meet content of the research of numerical simulation and remaining oil distribution. While the history match is also very precise and the errors are all less than 8.21%. So it is demonstrated that simulation in this area is fit for anticipating the remaining oil distribution. After all the research on exploitation technology make rational calculation for variese schemes to guide the exploitation in future.
