摘要採用預鉆井方式開發的海上油氣田，對水下鉆井基盤鉆井槽孔用完后增鉆的調整井，可採用無基盤鉆井方式作業。The measurement of oil / water two - phase flow is primarily accomplished by the combination of total flow rate and holdup measurement, and at present, the rotator flowmeter is used to measure the total flow rate. since the rotator flowmeter has movable parts, which makes its responsibility behave nonlinearly under poor environment of me under hole whose fluids have very complex and changeful characteristics and affects the measurement precision. what ' s more, the widely used centralized measurement instrumentation meets problems in oil wells characterized with high production or high water cuts
通常油水兩相流測量主要是通過總流量和持率的測量組合來完成的，目前在總流量的測量中主要使用的是渦輪流量計，由於渦輪流量計具有可動部件使其在流體特性復雜多變的惡劣井條件下的響應呈非線性變化規律，影響測量精度，此外，普遍採用的集流型測試儀器在高產井及含水率高的油井中使用也遇到困難，為此，一種新型的適合非集流型點測的測試方法和測試儀器亟待發展和推廣。To braided stream deposit, the fluvial sand body is distribute largely and continuously, so the heterogeneity is poor relatively, the relation of injection and production is better in the case of rare wells, about all wells have come on water, only in some thin sandbodys or bad physical layers there is some low flooded strata
對辮狀河砂體，平面上大面積連續分佈，在平面及層內非均質性弱，在較稀的井網下注采關系就較完善，目前平面上幾乎所有井點都已水淹，只有局部由於砂體厚度變薄，物性相對變差而存在一些低水淹部位。This article is mainly aim at tuo28 down reservoir of shengli oil field. through deeply analysis of geological character and its developing course. the important problems are found, first, flood pattern is not perfect, the reserivor is serious watered out in horizontal section, waterflood susceptibility is bad, the contradiction between oil and water in reservoir is serious, the interference between each producting formation is great, the crude oil is density, the reservoir have not enough energy, anisotropies is very serious. due to those facts, it is difficult to improve oil production by general technique
本文通過對勝坨油田坨28下油組油藏地質特點及開發歷程的深入分析，找出目前存在的主要問題有：注采井網不完善，平面上水淹嚴重，注水效果差，油水矛盾突出，層間干擾嚴重，原油稠，油藏能量低，儲層非均質性強，致使常規彩油工藝開發難度大。The paper also introduces the scope, tasks, approaches, and goals of sandstorm source control project in and around beijing and tianjin, pointing out the danger of solely depending on drilling 286 400 wells and pumping excessively the underground water to maintain vegetation of trees and grass, for once the ground sinks, the underground reservoir will disappear forever
同時文章介紹了京津風沙源治理工程的范圍、任務、方式和目標，並指出完全依靠打28 . 64萬眼井，長期超采地下水來維持林草植被生長，一旦引起地面下沉，會永遠失去地下水庫。In the literature, the flow equations for partial penetrating wells are based on two - dimensional model with impermeable upper and lower boundaries, and they cannot reflect the characteristics of bottom water drive mechanism, while the new equations presented in this paper can accurately describe the deliverability of partial penetrating gas wells with non - darcy flow pattern in gas reservoirs with bottom water
目前仍使用改進的上下封閉邊界的裘比公式，未能充分地反映底水驅動特點，而該公式能準確地描述底水驅動的打開不完善井非達西流動規律下的產能。When the relief work was completed at barmer, the initiates learned that the local government had insufficient funds to build more underground water storage tanks and consolidate wells for the local communities. so the relief team immediately subsidized the purchase of materials to build 50 water tanks and consolidate 21 wells with the help of the mmba
在完成發放工作后，有鑒于當地政府缺乏資金，無法多為居民建設社區地下儲水槽及鞏固地下水井，同修們隨即補助巴摩爾地區購買工程所需物資，在mmba組織的協助下建設了50個水槽，並展開21口井的鞏固工程。分享友人
