摘　　要：对现河庄油田的地质特性及其中深井（井深为3100～3900m）特点进行了分析。随着近几年高效牙轮钻头、PDC钻头、防斜打直、滑动钻具连续导向钻井、钻井液和处理剂等常规技术的成熟，以及三维力学导向技术和软件、全过程欠平衡钻井、50MPa井下涡轮增压器、天然高分子钻井液等新技术的应用，现河庄油田中深井的钻井速度有了大幅度提高，其中直井的平均机械钻速为17．22m／h，定向井的平均机械钻速为16．72m／h。This paper analyzes the geological natures of the Xianhezhuang Block,and the characteristics of the medium-deep(3100-3900 m) wells in this area.Drilling rates in Xianhezhuang were greatly increased with the wide use of high-performance roller bits,PDC bits,and the technologies,such as 'prevent well deviation while drill straight',Slide Drilling Continuing Steering Technology,drilling fluid and additive techniques,as well as the application of 3-D mechanics steering technology and the computer software,under-balanced drilling in the whole well,the 50 MPa downhole turbine booster,etc.the rate of penetration(ROP) of vertical wells averaged 17.22 m/h,while that of the directional wells averaged 16.72 m/h.
