| Abstract: | With strong heterogeneity, the reservoir types and the relationship between the oil and water arecomplex, leading to the difficulty for the development of the Ordovician reservoir in Lungu Oilfield. The oil recoveryefficiency of the reservoir was improved mainly by elastic drive and water injection to supplement the energy in theearly stage, but by the waterflooding it is difficult to use the isolated oil (like in the attic) on the top above theoverflow. The mechanism and applicability of gas-flooding are discussed in view of the difficult problem that a largeamount of remaining oil can not be recovered in the high position around the well. Based on the field test of N2 huff -and-puff, numerical simulation method is used to systematically study the influence of the factors such as oilviscosity, water-body energy and the like on the effect of the huff -and -puff in the individual well. The gas injection parameters such as the injected gas amount per round-time, gas injection rate, well shut-in time and so on were optimized so as to further optimize the individual well gas -flooding technical policies for the carbonate fracture-cavity reservoirs in the Lungu Oilfield. |
