将选择调剖井的渗透率、吸水剖面、注入动态、压降曲线、采出程度一含水关系等5项因素,利用知识的不确定性表示方法表示成区块整体调剖选井的决策因子来优选调剖井,并利用注入动态来优选堵剂类型和堵剂用量,提出了最佳的施工工艺参数,研究了一套施工效果的预测方法,并从开采曲线、增产效果、增加可采储量、增加采收率、降低含水率、降低产水量等方面评价调剖改善的开发效果,从压降曲线、吸水剖面等方面评价调剖井的施工效果,实现了区块整体调剖从选井决策→堵剂决策→施工设计→效果预测→效果评价的一体化。并在盘2-26块应用中取得了显著效果。
We will select the five factors of permeability, water absorption profile, injection dynamic, pressure drop curve, water content relationship and so on of a profile-controlled well, and use the uncertain expression of knowledge to represent the decision factors To optimize the profile control well, and use injection dynamic to optimize the type of plugging agent and dosage of plugging agent, put forward the best construction process parameters, and study a set of prediction methods of construction effect, and from the mining curve, increase production effect, increase recoverable Reserves, increase oil recovery rate, reduce water cut, reduce water production and other aspects of evaluation of the development of profile control and improvement, from the pressure drop curve, water profile and other aspects of the evaluation of the construction effect of profile control wells to achieve the overall block profile from the election Well decision-making → plugging decision-making → design → effect prediction → effect evaluation of the integration. And in the disk 2-26 block application has achieved remarkable results.
