摘 要: | 对水井分层注水进行评价,可直观体现出注水井分层注水前后的效果,为此针对各因素对水井井组影响的不确定性,建立了一套适用于井组评价的定量化方法。在对井组进行注水效果评价之前,对现有各井做出评价,并利用模糊综合评判的方法计算出井组综合评价系数来评判各个井组的性质。结合普17断块的实际地质和开发状况,根据计算得出的综合评价系数E2,找出E2值与注水效果的递增关系,通过综合系数E2值评价出各井组注水效果的优劣,既可以评价井组分层注水是否合理。

Effect Evaluation of the Separate Layer Water Injection by Using Fuzzy Comprehensive Evaluation Method |
| |
Abstract: | Effect evaluation of the separate layer water injection can directly reflect the effect of injection wells before and after the separated layer water injection. Considering the uncertain impacts on injection well arrays, a set of appropriate quantitative method was established for evaluation of well arrays. Prior to the efficient evaluation of water injection well arrays, existing wells were first evaluated, then the fuzzy comprehensive evaluation method was used to calculate comprehensive evaluation coefficient of well arrays to judge the nature of every well array. Combined with the actual geological and development conditions of Pu17fault, comprehensive evaluation coefficient E2 value was obtained, the incremental relationship between E2 values and water injection effect was determined, the effect of water injection well array was evaluated to determine whether separated layer water injection was reasonable or not. |
