摘要:
针对层状边水稠油油藏储层质量差异大和水淹规律认识不清两大难点，在J块火驱先导性试验区完钻取心井一口，通过储层四性、沉积特征、核磁共振及气测解释等方面的研究，建立储层质量分类标准，完成储层质量评价，并且通过水淹动用判别及水淹规律分析，建立水淹强度分类标准，完成水淹层评价。该次研究明确了J块火驱先导性试验区的水淹规律，得出了不同主力层段水淹特点不同，仅个别高渗层水淹，中强水淹层段比例仍较低的重要认识，指导了该块火驱试验井组的层段组合优选与个性化参数设计。
The heavy oil reservoir quality of layered edge water varies greatly and it is difficult to recognize the water flooded rule. For the above two questions, take a hole in the fire drive pilot area of block J. Through the study of reservoir four, sedimentary characteristics, nuclear magnetic resonance and logging data interpretation, to carry out the classification of reservoir quality, and complete reservoir quality evaluation. Through water flooding uses discrimination and water flooding rule analysis, to classify the water intensity, and complete the water flooding evaluation. The study has clearly defined the water flooding rule in the fire drive pilot zone of block J. It is concluded some important understanding that the water flooding characteristics of different main layers are different, only the individual high permeability layer is flooded, and the proportion of moderately strong water flooded strata is still low, which guide the optimal selection of the layer segment and personalized parameter design of fire drive test well group in block J.
