锦州16高压气井的技术特点及其认识

Technique feature of JZ 16 High Pressure Gas Well and Opinion

渤海公司在锦州16井的钻探工作中开创了渤海自营勘探的三项新记录,其一是该井压力系数为1.89,地层压力为74.9MPa,最大泥浆密度为1.97g/cm^3,创造了自锦州20—2气田开发以来,最高压力记录;其二是井深4200m,创渤海自营勘探最深井记录;其三是全井安全顺利,创高压井钻井安全记录。

This paper describes three new records of Bohai self financed exploration in JZ 16 well drilling which have been produced since JZ 20 - 2 gas field being developed, including the highest pressure record with well pressure coefficient 1. 89, formation pressure 74. 9 MPa, maximum mud density 1. 97 g/cm3; the deepest well record with well depth 4 200 m in Bohai self financed exploration; the well safety record in high pressure gas well drilling. A set of successful experiences is summarized on the basis of drilling practice of the well.
