【摘要】：在油田開采過程中,與常用的直斜井技術(shù)相比：叢式井布井方案的建設(shè)投資少,地表破壞少,由于既能減少建設(shè)投資和運行費用,又能有效地保護環(huán)境,叢式井布井技術(shù)已成為油田開采的熱點技術(shù)之一,并從最初的環(huán)境受限地區(qū)擴展到了低產(chǎn)低效的油田。而設(shè)置多少個地面平臺、平臺內(nèi)有多少口直斜井、平臺中心井的位置設(shè)在什么地方使油田開發(fā)運行最優(yōu)成為叢式井布井技術(shù)迫切需要解決的問題。本文主要研究采用叢式井技術(shù)開發(fā)整裝區(qū)塊過程中,如何使油田建設(shè)總投資最小的優(yōu)化問題,包括：鉆完井、地面建設(shè)以及運行等各項費用對油田建設(shè)總投資的影響。主要內(nèi)容包括：1、針對鉆完井費用優(yōu)化問題,建立了鉆完井系統(tǒng)費用模型。在綜合考慮地面條件、地理位置等無法建設(shè)因素的前提下,基于鉆完井系統(tǒng)費用優(yōu)化模型,通過優(yōu)化求解,可得出平臺位置,既能滿足現(xiàn)場安全鉆井施工的要求,又能大幅降低鉆完井綜合費用。2、針對油田地面建設(shè)費用優(yōu)化問題,建立了油田地面建設(shè)費用模型。油田地面系統(tǒng)是由相應(yīng)轉(zhuǎn)油(注水)站、配水間(閥組間)、注水井及連接它們的管網(wǎng)、道路以及電力線路組成的復(fù)雜的集輸處理網(wǎng)絡(luò)系統(tǒng),在叢式井平臺的數(shù)量、位置及與其相連集輸管線給定的情況下,研究了系統(tǒng)中油井對平臺、平臺對閥組間、閥組間對轉(zhuǎn)油站的歸屬關(guān)系,并對平臺中心井的位置進行優(yōu)化,降低油田地面建設(shè)費用。3、針對油田建設(shè)總投資最小問題,建立了叢式井平臺位置優(yōu)化模型和油田建設(shè)總投資(鉆完井費用+采油工程費用+地面工程建設(shè)費用+運行費用)最小的優(yōu)化命題,通過優(yōu)化求解得出平臺的優(yōu)化位置。開發(fā)了叢式井平臺優(yōu)化分析軟件,實踐證明所建立的優(yōu)化模型的有效性。最后對全文進行了總結(jié)和對未來進行了展望。
[Abstract]:In the process of oilfield production, compared with the common technology of straight inclined well, the construction investment and surface damage of cluster well layout scheme are less, because it can not only reduce the construction investment and operation cost, but also protect the environment effectively. The cluster well arrangement technology has become one of the hot technologies in oilfield production and has been extended from the initial environment limited area to the low production and low efficiency oil field. However, how many surface platforms are set up, how many vertical inclined wells are located in the platform, and where the location of the platform central wells is located makes the optimal development and operation of oil fields an urgent problem to be solved by the well layout technology of cluster wells. In this paper, the optimization problem of how to minimize the total investment in oilfield construction is studied in the process of using cluster well technology to develop the whole block, including: drilling and completion, surface construction and operation, etc., which affect the total investment of oil field construction. The main contents are as follows: 1. Aiming at the optimization of drilling and completion cost, the cost model of drilling and completion system is established. Based on the cost optimization model of drilling and completion system, the platform position can be obtained by considering the ground condition, geographical location and other unconstructable factors, which can meet the requirements of safe drilling construction on the spot, and based on the cost optimization model of drilling and completion system, the platform position can be obtained by optimization. It can also reduce the comprehensive cost of drilling and completion. 2. Aiming at the optimization of the cost of oil field surface construction, the paper establishes the model of the cost of oil field surface construction. The oil field surface system is a complex gathering and processing network system composed of corresponding oil transfer (water injection) stations, water distribution stations (valve groups), water injection wells and the pipe networks connecting them, roads and power lines, and the number of platforms in the cluster wells. In this paper, the relationship between the oil well pair platform, the platform versus valve group, the valve group and the valve group is studied, and the location of the platform central well is optimized under the given position of the location and the connected gathering pipeline. Reducing the cost of oil field surface construction. 3. Aiming at the problem of minimum total investment in oil field construction, The optimization model of the platform location of cluster wells and the optimal proposition of the minimum total investment of oil field construction (drilling and completion cost, oil recovery engineering cost, surface engineering construction cost) are established, and the optimal location of the platform is obtained through optimization solution. The optimization analysis software of cluster well platform has been developed, and the effectiveness of the optimization model has been proved by practice. Finally, the paper summarizes the full text and prospects for the future.
