永进油田油藏为复杂的岩性、地层超覆共存的油气藏,油藏特征为埋藏深、低孔-超低渗、无边水,开发难度较大,结合钻井工艺、地面工程以及原油性质分析,该区适合弹性开发。本文利用油藏数值模拟技术,通过建立该区的地质模型,优化了井型、水平井方位、水平段长度以及井段在油藏中的位置等开发政策界限,研究成果对该油藏的高效开发具有重要的指导意义。
The reservoirs in Yongjin Oilfield are complex lithologies, and the strata overlie the coexisting reservoirs. The reservoirs are characterized by buried deep, low porosity - ultra-low permeability and infinity water, which is difficult to develop. Combining with drilling technology, ground engineering and crude oil properties Analysis, the area suitable for flexible development. Based on the reservoir numerical simulation technique and the establishment of the geological model of the area, the paper optimizes the development policy boundaries such as well type, horizontal well location, horizontal section length and well location in the reservoir. The research results show that this reservoir is highly efficient Development has important guiding significance.
