Effected by many factors during huff and puff, the reservoir of edge water invasion and complex small fault block, the producing wells which are located in the neighborhood of the fault trace and oil - water contact, are quite difficult for development
摘要由於在蒸汽吞吐開發過程中要受到多種因素的影響，而且生產井處于斷層和油水邊界附近，所以層間水復雜小斷塊稠油油藏的開發難度較大。The search space is divided into many small areas, and each area is given a certain pheromone value. according to the state transition rules, the artificial ants move to the next solution which is generated randomly or calculated by particle swarm optimization. local search strategy is also added into psaco so that the search speed and precision is enhanced
該演算法首先將連續對象定義域平均分成許多邊緣相互重疊的小區域，區域的稠密程度決定了演算法解的精度，每個區域賦予一定的信息素值;螞蟻根據狀態轉移規則在隨機生成的可行解與利用微粒群演算法得出的可行解之間選擇下一步要去的位置;引入局部尋優策略，加強近似最優解鄰域內的局部搜索，提高搜索速度和精度。Bated on the dynamic and static data from different heavy - oil reservoirs in liaohe oil - field, starting front the theory of percolation flow through porous media, stress analysis and micro tropic reservoir features, and in combination with consideration of sand production regularity, the sand production mechanism and major factors to control sand production are discussed for heavy - oil reservoirs, and the technical strategy of sand control is proposed
摘要以遼河油田不同類型稠油油藏的動、靜態資料為基礎，從多孔介質中流體滲流理論、應力分析及儲層微觀特徵等方面入手，結合油層出砂規律，對稠油油藏出砂機理及影響出砂程度的主要因素進行了分析，提出了稠油油藏防砂技術對策。
