Under the economic constraint conditions,the economic limits of new development wells reflect the demand of investment decision-making.
在经济约束条件下新钻井经济界限主要体现了投资决策要求。
Facing the technical challenges of logging in horizontal wells, and combining with the application of new drilling techniques, this paper studies a logging method for horizontal wells which is different from conventional geological logging technology so as to make full use of the geological orientation significance of logging in horizontal wells.
针对水平井录井过程中存在的技术难点,结合钻井新工艺的应用,探讨出一种有别于传统地质录井技术的水平井录井方法和对策,旨在充分发挥水平井现场录井的地质导向作用。
New aerated foam drilling fluid, using a special plant fiber named KWS as fluid material, not only has the characteristics of low density, high ability of removing cuttings and lower use of water, but also has the perforation of rejecting of the Na~+ s and Ca~(2+) s affection.
利用特殊植物纤维KW S作为泥浆处理剂的新型充气钻井液,不仅具有常规充气钻井液低密度、排粉能力强、节约用水等优点,还可以不受钠、钙离子的影响,提高钻井泡沫稳定性和钻井液抗盐能力。
