Buried Hill

Buried hill reservoir fracture description and reservoir simulation technology have been a hot research, but also is one of the key issues that restrict the efficient development of such reservoirs. Based on JZ buried hill reservoir which heterogeneity is strong, some wells water channeling fast and difficult to control the situation for fracture affect, a typical block of dual medium reservoir numerical models which was comprehensive variety of information, discrete fracture characterization and geological modeling is established. The fractured reservoir numerical model is simulated through Eclipse software to seek the law of remaining oil distribution. Through the reservoir geological reserves and production history matching, the remaining oil distribution of main production horizon is forecasted. On this basis, the results of different oilfield development adjustment programs are predicted by numerical simulation.

Remaining Oil Distribution

The BQ57 block is structurally located in the sag part of Biyang, the northern slopes. Reservoir is buried shallow, thickness thin and oil viscosity is high. With the old wells production factor decreasing, the remaining oil distribution is getting more and more complex, the block has a downward trend in production capacity. In this text, we longitudinally divided the BQ57 block into several emulation layers, horizontally divided into grids, established the block reservoir numerical model using the reservoir numerical simulation software, fit the daily fluid production, daily oil production, water cut, diurnal injection of this block, and the single well production history by adjusting the model parameter values, which the fitting error of each index were all within 2%[1,2]. On the basis of the results of numerical simulation, statistical analysis the remaining oil distribution and reserves abundance condition, clarify the regularities of distribution of the remaining oil, so that we can effectively produce the remaining oil, and it has an important significance for improving the recovery rate in oilfield.

Water Cut

Sanan oilfield has entered late stage of high water cut development. It urgently needs accurate prediction of remaining oil distribution. But previous studies on 3D structure were far could not meet the requirements of fine reservoir description. This paper applied RMS, a piece of excellent geological modeling software establishing the 3D fine structural model of typical block in Sanan oilfield on the bases of 3D fine seismic structural interpretation data. It included the 28 faults’ model, 11 horizons’ model and the structural model. And then measured and analyzed the faults elements data. Based on abundant geologic data, well data and seismic data of the block, this structural model reproduced the fine seismic interpretation results accurately. It was really fine enough to meet the requirements of the fine reservoir description. This research solved the problem that traditional modeling techniques could not handle complex cutting relationship of faults’ model. It laid a solid foundation for reservoir numerical simulation and remaining oil distribution prediction.
