本文从油井的试油结果、初期产能、单井生产状况、见效见水特征、注采对应关系、水驱油运动规律及剩余油分布特征等方面对影响侯市区东部动态特征的地质因素进行了剖析。研究表明:当注采井分布在有利相带时,往往试油产量高、油井见效快见水也快,否则较慢;储层地质特征是影响水驱油运动规律及剩余油分布特征的主要因素,注入水往往在平行于古水流方向、河道的主体带推进速度较快,研究区目前孔隙渗流区水淹井的来水方位几乎均平行于古水流方向;垂直或斜交于古水流方位、非有利相带将是剩余油的富集区域;储层裂缝的存在也严重地控制了注入水流向,注入水沿裂缝方位窜进,其他方位将是剩余油富集的主要区域。
In this paper, the geological factors influencing the dynamic characteristics of the eastern part of Hou City are studied from the test results of oil well, initial production capacity, production status of single well, characteristics of visible water, correspondence between injection and production, movement law of water flooding and remaining oil distribution Analysis. The results show that when the injection and production wells are distributed in favorable facies belt, the production of test oil is often high, the seepage of the oil well is fast, and otherwise the water is quicker. Otherwise, the geological characteristics of reservoir are the main factors influencing the movement law of water flooding and the remaining oil distribution In the study area, the incoming water level of the flooded wells in the seepage area is almost parallel to the direction of the paleocurrents, and the vertical or diagonal to the direction of the paleocurrents , And the non-favorable facies belt will be the remaining oil enrichment area. The existence of fractures in the reservoir also seriously controls the flow of injected water. The injected water flies along the fracture orientation and the other azimuths will be the major areas where residual oil is enriched.
