【摘要】：针对新疆吐鲁番地区雁木西油田区块,该区块以第三系和白垩系为主要目的层位,该段层位以盐膏层为主,上段井径扩大率较大,井壁容易垮塌,在下段油层段内容易缩径。同时,盐膏层易污染水泥浆,使水泥浆闪凝,造成固井事故;周围注水井多,钻井液比重1.48 g/cm~3,侯凝过程中压稳困难。为此,西部钻探钻井工程技术研究院首次在该区块雁673井使用了自主研发的ZYY-139.7振动胶塞,该系列振动胶塞控制部件和胶塞部件设计合理,结构独特,动作灵活可靠,承压差性能高,能有效地通过振动波作用于套管壁以提高固井质量。经声幅/变密度测井结果显示,该井固井质量优质。这为雁木西区块乃至整个吐哈地区优质固井施工提供了技术借鉴。
[Abstract]:In view of Yanmuxi oil field block in Turpan area Xinjiang Tertiary and Cretaceous are the main target horizons which are mainly salt and gypsum layers with large expansion rate of well diameter and easy collapse of wellbore. At the same time, the salt paste is liable to pollute the cement slurry, make the cement slurry flicker, and cause cementing accident. There are many water injection wells around, and the specific gravity of drilling fluid is 1.48 g / cm ~ (-3). For the first time, the West drilling drilling Engineering Technology Research Institute has used the ZYY-139.7 vibratory rubber plug developed by itself in the Yan673 well in this block. The series of vibration plug control parts and rubber plug components are designed reasonably. The structure is unique, the action is flexible and reliable, the performance of pressure difference is high, and the cementing quality can be improved effectively by vibration wave acting on the casing wall. The results of acoustic amplitude / variable density logging show that. The cementing quality of the well is excellent, which provides a technical reference for the high quality cementing operation of Yanmu West Block and even the whole Turpan-Hami area.

【正文快照】： 吐哈雁木西油田现阶段处于二次开发阶段,由于长期注水开发,地层压力普遍较高,目前钻井液密度基本在1.45 g/cm3以上,最高可达1.67 g/cm3。目前雁木西区块所钻井为加密调整井,周围生产井多,候凝过程中生产井并不停产。候凝时环空水泥浆会因地层流体扰动而被替换,从而油层段形成
