利用三维地质资料和油藏数值模拟技术,对文51 断块进行油藏构造精细描述和剩余油分布研究。在反复加深油藏认识的同时,运用高压脉冲解堵、液态压裂、堵水调剖和大修等多元技术对油藏实施综合挖潜,实现了对剩余油挖潜增效的目的,而且针对性强、经济有效率高,对储层不会产生二次污染。

Based on the 3-D seismic interpretation and reservoir numerical simulation ,the precise description of reservoir structure and remaining oil distribution was made in Block Wen 51. Further more ,with repeated study and clear recognization of the block ,the multivariate technologies , such as high pressure impulse deplugging ,liquide state fracturing ,profile control with water shut off and major repair ,were combined to tap the oil production potential ,so the main oil content ration zones are found , and no secondary pollution is made to the reservoir.
