【摘要】：高3618块莲花油层为一厚层块状稠油纯油藏,含油面积1.16km2,地质储量1323.3×104t,标定采收率14.6%。于1987年采用蒸汽吞吐开发方式投入开发,近年来受油藏地质特点及蒸汽吞吐末期采出程度高,地层压力水平低,继续吞吐效果差等影响,产量递减较快,最终采收率低。本次结合区块已完钻井的钻井、录井、测井及三维地震等资料,利用精细地层对比技术、储层综合评价技术、测井识别技术、地质建模技术、剩余油研究及数值模拟技术等,综合对高3618块莲花油层的构造特征、沉积特征、储层特征、油藏类型、油水关系、地质储量、蒸汽吞吐开采效果、剩余油分布规律进行深入研究与评价。在此基础上,根据精细油藏描述地质体认识和剩余油分布和潜力提出了下一步提高采收率的合理开发方式。
[Abstract]:The high 3618 Lianhua reservoir is a thick layer thick oil pure oil reservoir with an oil area of 1.16km2 and a geological reserve of 1323.3 x 104t. The calibrated recovery rate 14.6%. was developed by steam stimulation development in 1987. In recent years, the reservoir geological characteristics and the stage of steam stimulation at the end of the period are high, the level of the ground pressure is low, and the effect of continuous huff and puff is poor, and so on. In this combination, the drilling, logging, logging and 3D seismic data have been completed in this area, and the structural characteristics of the 3618 High lotus oil layers are integrated with fine stratigraphic contrast technology, comprehensive reservoir evaluation technology, logging recognition technology, geological modeling technology, residual oil research and numerical simulation technology. The product features, reservoir characteristics, reservoir types, oil and water relations, geological reserves, the effect of steam huff and puff exploitation and the distribution of residual oil are deeply studied and evaluated. On this basis, a reasonable development method for the next step of high recovery is proposed based on the description of the geological body and the distribution and potential of the remaining oil in the fine reservoir.
