TK1115-5H井油层压力严重衰减,属于超低压油气层,充分说明了调整井身结构以前的三开井段同一裸眼地层上下压差很大,在钻开油气层后,导致了先后出现四次卡钻现象。在适时调整该井井身结构以后,该井后期安全顺利完成施工任务,为以后开采该类型油层的钻井施工提供了一个成功的先例。 TK1115-5H well oil layer pressure decay seriously belongs to the ultra-low pressure reservoirs, fully justified the well bore structure before the open hole section of the same open hole pressure difference between the naked eye is very large, after drilling in the oil and gas, resulting in has appeared four times Card stuck phenomenon. After timely adjusting the well structure of the well, the well completed the construction task safely and safely in the late period, which provided a successful precedent for the later drilling of this type of oil layer.
