孔雀1井试油工艺方法

孔雀1井是塔里木盆地孔雀河区块投入的首口试油井,目的是求取各层液性、产能、压力及有关地层评价参数,为进一步开展该区地震资料解释和石油地质综合研究提供依据。通过这口井的试油为这一区块摸索出一套工艺方法。即优质无固相压井液与负压射孔相结合,并在管柱结构上充分考虑深井测试管串减震及安全因素,以三开两关射测联作配合深穿透、大孔径方式射孔,达到快速科学试油,从而提高试油测试成功率。

Formation testing technology in Kongque 1 well

Kongque 1 well is the first well being put into formation testing in Kongquehe block in Tarim basin. The goal of formation testing is to achieve each layer's fluid properties, deliverability, pressure and the relevant formation appraisal parameters, so as to provide a basis for future seismic interpretation and comprehensive study of petroleum geology. Solid - free well control fluid and underbal-anced perforation technology are used, and much attentions are paid to amortization and safety factors of testing pipe string in deep wells when designing pipe string structure. Perforation and testing are carried out jointly and perforation is carried out with deep penetration and large aperture diameter methods. The success ratio of formation testing is improved.
