求翻译：欠平衡钻井技术是准确发现和评价油气资源的方法之一，尤其适合评价和开发低压低渗油气层。欠平衡钻井边喷边钻，可减少或避免井漏和压差卡钻等井下负责事故、减少对地层的污染、提高机械钻速、发现产层和提高产量、减少完井作业费用等。多口井欠平衡钻井实施中发现良好的油气显示，为打开松南地区勘探开发的新局面，增储上产提供了技术支持。是什么意思？

Underbalanced drilling technology is accurate discovery and a method of evaluation of oil and gas resources, especially for the evaluation and development of low-pressure-permeability reservoirs. Less side spray balanced drilling and drilling, can reduce or avoid lost circulation and differential st

Whether or not it is accurately balanced drilling technology discovery and evaluation of oil and gas resources, in particular one of the methods for evaluation and development of low voltage seepage oil and gas. To balance the boom while drilling rigs, wells may be reduced or avoided leakage and pre

Underbalanced drilling technology is one way to accurate discovery and evaluation of oil and gas resources, especially for evaluation and development of low pressure and low permeability reservoir. Side spray side drilled under-balanced drilling, can reduce or avoid leakage and pressure differential
