高3块蒸汽吞吐阶段储量动用程度研究及挖潜措施

Study on producing drgree of reserves and potentiality tapping measures of steam soak phase in block Gao 3

为了解决高3块开发中储量动用程度差的状况，采用容积法、产量特征曲线法和数值模拟法选择合理井网．以提高平面储量动用程度；通过物理模拟法，确定改善油层纵向动用程度的开采方式。结果表明：蒸汽吞吐开采最优井距为105m；改善开发效果最佳注汽方式为全面注汽，注热水开采效果也较好，但需提高注入速率。

In order to solve the problem of low producing degree of reserves in blockGao 3,rational well pattern is selected by uslng volumetric method, production feature curveand numerical modeling,thus enhancing areal producing degree of reserves; production modefor enhancing vertical producing degree is determined by physical modeling. The result is thatthe optimal well spacing is 105 m for steam flooding, the optimal steam injection mode isfield-scale steam injection; hot waterflooding is also good, but the injection rate should behigher.
