钻井进尺

合理的钻头选型可以明显提高机械钻速和获取更多的钻井进尺，是实现优化钻井的关键技术之一。

Correct bit selection is one of the key techniques that can improve both the drilling rate and footage largely increased .

钻井进尺的增加必然导致相应的材料需求增加，特别是油田化学品消费需求与钻井进尺呈正相关的关系。

Increasing of drilling footage will surely increase the demands for corresponding materials , especially that consumption demands for oilfield chemical products are positively correlated with the drilling footage .

减少地震工程中的测量工程量、钻井进尺是提高地震勘探效益的其他途径。

Cutting down of survey workload in seismic engineering and the drilling footages might be another methods to uplift the benefit of seismic 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。

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 .

为满足快速发展的需要，钻井的进尺增长速度必须安全、稳步提高才能实现公司的发展目标。

In order to meet the fast-developing need , the well drilling should be improved the safe and footage growth rate and can just realize the goal of development of the company .

该预测模型表明钻井成本与钻井进尺和钻井周期呈指数关系。

This forecast model shows that there exists exponential relation between the drilling cost and the footage and the cycle respectively .

为此，采用实证研究方法，针对油气钻井作业的过程提出两个假设：①钻井作业成本与钻井进尺呈一定的比例关系；②钻井作业成本与钻井周期呈一定的比例关系。

Therefore , a positive research method was a-dopted to put forward two hypotheses during the oil and gas drilling works , i. e. a certain relation existed between operation 's cost and drilling footage and cycle respectively .

胜利石油管理局海洋钻井公司23年来，在渤海湾4870km2的海域内，已打井348口，完成钻井进尺737866m。

A total of 348 wells and an overall footage of 737,866 m have been drilled by the Offshore Company of Shengli over the 23 years .
