为了满足江汉油田试井工作中深井测压的需要,我们在毛主席“独立自主、自力更生”的方针指引下,在武汉仪表局和江岸仪表厂的大力支持下,经过室内79次和现场32次反复试验,试制成了500大气压深井井下压力计,基本上满足了油田深井测压的需要,目前已小批生产,投入现场使用。一、500大气压压力计结构性能及用途 1.结构型式: 此仪器采用CY 613—A型井下压力计外壳改装而成,其心脏部分一螺旋弹簧管采用国产的锡磷青铜管制成。它是能耐压500公斤/公分~2和耐温150℃的弹性元件,其
In order to meet the needs of deep well manometry in well testing in Jianghan Oilfield, under the guidance of Chairman Mao’s principle of “independence and self-reliance,” with the strong support of Wuhan Instrument Bureau and Jiang’an Instrument Factory, after 79 indoor and 32 repetitions Test, trial made into a pressure of 500 atm deep underground pressure gauge, basically meet the needs of deep well oil pressure measurement, has been a small batch of production, into the field. First, the 500 barometric pressure gauge structure performance and use 1. Structure Type: This instrument uses CY 613-A downhole pressure gauge shell converted from the heart part of a coil spring tube made of domestic tin phosphorus bronze tube. It is able to withstand 500 kg / cm ~ 2 and temperature of 150 ℃ elastic components, which
