【摘要】 酸化、压裂是油田的重要增产措施，目前已经普遍应用于开发生产中。通过酸化和压裂，可以在一定时期内增加一定的原油产量，因而采取酸化、压裂措施对油田的增产和稳产起到了重要的作用。但是，酸化、压裂的作业费用是十分可观的。如果通过实行酸化、压裂而增加的原油销售收入不足以弥补酸化、压裂作业费和增加的采油成本，就会导致利润减少，影响企业的经济效益。因此为了保证酸化、压裂措施不仅能够促进原油的稳产或增产，同时也能够增加企业利润，就必须对酸化、压裂措施的经济性进行分析和评价。 过去由于石油企业的生产以原油的稳产和增产为主要目标，因而对酸化、压裂措施的经济性并不十分关心。但近年来，随着石油企业改革的不断深入，油田开发企业更加重视经济效益，因此对酸化、压裂措施的经济性也越来越关注。井下酸化、压裂的经济分析的研究这一课题就是在此情况下根据油田开发的需要提出的。 本文以井下酸化、压裂措施为对象，对方案的经济性进行分析。本文根据井下酸化、压裂措施的特点，利用神经网络知识对日增油效果进行预测并提出投资、成本费用的测算方法。 本文根据酸化、压裂有效期较短的特点，在评价时采用差异分析方法，对由于酸化、压裂作业而增加的销售收入和成本费用进行比较，计算差异利润。本文根据盈亏平衡原理对酸化、压裂措施进行经济界限分析，并建立经济界限模型。 本文开发了经济评价系统，并将其应用于实际，因此本文的研究具有一定的创新性和适用性，它将为油田开发决策提供可靠的理论、方法和工具。更多还原

【Abstract】 Acidification and fracturing is an important measure for increasing oil production, and has been widely used in the exploitation. The oil output can be increased at a certain extent in a period of time through acidification and fracturing, which plays an important role in increasing and maintaining oil output in the oilfield. But its expense is quite considerable. If the added oil revenue by carrying out acidification and fracturing can not meet the added cost, the profit will be decreased and the benefit of the oilfield will be influenced. Therefore, the economic analysis and evaluation on acidification and fracturing must be conducted in order to increase or maintain oil output and increase the profit of the oilfield as well.Since maintaining and increasing oil production being is a principle objective in the petroleum enterprise in the past, the economical efficiency of acidification and fracturing has not been thought much by the oilfield. But in recent year, along with the continuous deepening of petroleum enterprise reformation, the benefit is thought much of by oil field. And also the economical of acidification and fracturing attract more attention. In terms of the demand of oil field development, the subject of acidification and fracturing economic analysis is put forward.This paper takes acidification and fracturing measure as an object and analyzes the economical efficiency of the project. According to the characteristic of acidification and fracturing, this paper utilizes nerve network knowledge and predicts daily added oil effect and put forward the estimating method for investment and cost.According to the characteristic of acidification and fracturing that the availability period is short, this paper adopts odds analysis method and compares the added sales revenue and the according cost of acidification and fracturing, then calculates the odds profit. According to the principle of the balance between profit and loss, the paper analyzes the economic boundaries of acidification and fracturing and establishes the model of the economic boundaries.This paper develops the system of economic evaluation and applies it into practice. Thus this paper has certainly innovation character and holds applicable character.更多还原
