摘要:

吉林油田深层天然气藏存在埋藏深、钻速慢、成本高、储层敏感性强且易污染等问题,严重影响了储层的及时发现和单井产能发挥,同时制约了勘探开发步伐。为解决该技术难题,在分析吉林油田德惠区块岩性特点、物性特征、地层压力、地层流体及井壁稳定性的基础上,评价了在该区块实施氮气钻井的可行性,详细阐述了氮气钻井施工方案设计,包括注气参数设计、转换钻井液设计、风险应对措施等,并介绍了氮气钻井技术在德深35井的应用情况,对于后续推广应用该技术具有良好的借鉴意义,有助于加速吉林油田深层天然气藏的高效勘探开发。

The deep gas reservoir in Jilin Oilfield was characterized by deep burial, slow drilling rate, high cost, strong reservoir sensitivity and easy pollution, which seriously affected the finding of reservoirs and single well production, and restricted the pace of oil exploration and development. In order to solve the problem, on the basis of analyzing the characteristics of lithology, physical property, formation pressure, fluid in formation, and borehole stability, the feasibility of nitrogen drilling in the block was evaluated; the design of nitrogen drilling scheme, including gas injection parameters, drilling fluid transferring, risk control measures, etc., was expounded; and the application of nitrogen drilling technology in Well Deshen35 was introduced. It provides good reference for applying the technology in the future, and it is beneficial for speeding up oil exploration and development of deep gas reservoir in Jilin Oilfield.
