钻水平延伸井是为了最大限度地扩大油藏的泄油面积和降低因底水锥进而造成的产水量。这类油井在实施酸化处理中存在的问题是基岩酸化过程中布酸效果较差。讨论了一种新的工艺方法,即采用一种液压式牵引器牵引酸化施工用连续油管,使整个待酸化井段被酸化处理;采用一种黏弹性表面活性剂基酸液系统,消除因钻井液所造成的地层伤害。
The horizontal well is drilled in order to maximize the drainage area of the reservoir and to reduce the amount of water produced by the coning of the bottom water. The problem with such wells in the acidification process is that the acidification of the bedrock is less effective than the acidification of the bedrock. A new process method is discussed. A hydraulic tractor is used to tow coiled tubing for acidizing construction so that the entire section to be acidified is acidified. A viscoelastic surfactant-based acid liquor system is used to eliminate the problems caused by drilling Stratum damage caused by liquid.
