松软煤层水平对接井筛管完井工艺技术
Well completion technology by screen pipe for horizontally-intersected well in soft coal seam
摘要
Abstract
During the development of coalbed methane(CBM) in soft coal seam, the complicated geological conditions , the borehole sidewall instability and blocking of gas -producing channels lead to poor effect of gas drainage with horizontally-intersected wells in soft coal seam. The well completion technology directly affects the drainage effect of CBM, and in this paper, the well completion technology by screen pipe for horizontally-intersected well is studied, including selection of the screen pipe, development of equipment and screen pipe running operation technique, etc. Through field application in Jincheng-Chengzhuang coal mines, three horizontally-intersected wells were completed with a total length of 1466m screen pipe, and its application effect is good.关键词
