近年来,随着北区主力砂体优质补孔潜力减小,非主力砂体已经成为潜力接替的一个重要方向。我们利用现有资料,结合非主力砂体的地质构造特点、生产历史及油井测井曲线等动静态资料进行分析,通过对非主力砂体的储量动用程度现状调查、非主力砂体剩余油分布情况研究,优选含油小层进行以补孔为主,采取高压充填、酸化为主的改造手段,同时加强对供液不足的砂体进行注水补充地层能量,全面综合的进行提高北区非主力砂体动用程度研究。提高非主力砂地质储量采出程度0.09%,为以后非主力砂体进行更好的开发积累了经验。
In recent years, as the potential of high-quality fill holes in the North Main Sandstone decreases, non-main sand bodies have become an important direction for potential succession. Based on the existing data, combined with the geological structural features of the non-main sand body, the production history and logging data of well logs, we analyze the status quo of non-main sand reservoirs and the residual oil distribution in non-main sand bodies It is suggested that the oil-bearing small layer should be mainly filled with holes, and high-pressure filling and acidizing should be taken as the main reforming measures. Meanwhile, the sand supply with insufficient liquid should be recharged to replenish the formation energy and comprehensively improve the non-main sand Study on the degree of physical activity. The non-main sand production should be increased by 0.09%, which has accumulated experience for better development of non-main sand bodies.
