油田在生产中,经常会发生生产闸门在生产中被盗油破坏分子关闭,造成盘根刺漏,油井井口和地面污染,严重的导致油井泵憋坏。严重地影响了油井的正常生产,造成了不必要的原油损失和赔青费,增加了成本支出和工作量。因此,新型油井生产闸门的研制就显得尤为重要。 Oil production in the field, often occur in the production gate was stolen oil sabotage molecules closed, resulting in packing leaks, wellhead and ground pollution, causing a serious pump wells holding bad. Seriously affecting the normal production of oil wells, resulting in unnecessary loss of crude oil and pay the cost, an increase of costs and workload. Therefore, the development of new oil well production gate is particularly important.
