油田勘探总成本变动分析

An Analysis of the Total Costs of Oilfield Exploration

在研究勘探总成本的变动中，可以按区块、承包方式和井别进行简单分组，分别研究钻井进尺和平均成本对勘探总成本的影响。文中从复合分组的角度，分别研究钻井进尺、区块平均成本、区块钻井进尺结构、承包方式平均成本、承包方式钻井进尺结构、井别平均成本和井别钻井进尺结构变动对油田勘探总成本变动的影响。通过分析可以从各方面找出影响勘探总成本的因素，以便找到油田降低勘探成本的途径，最终达到提高油田经济效益的目的。

The total costs of oilfield exploration can be divided, according to exploratory area, contract method, and the type of well, into simple groups in order to evaluate separately the influence of drilling footage and average unit cost on the total costs. By this way, the factors affecting the total costs of exploration can be determined, and measures can be made toward reducing the total cost and enhancing the economic benefit of exploration. A composite grouping method is used in this paper.
