近期,中国石油西南油气田重庆气矿对川东石炭系超深水平井板东006-H1井注入转向酸1 530 m3、分11段成功实施大型酸化作业,创造了四川油气田注酸量和分段级数最多、石炭系水平段最长的超深水平井裸眼分段酸化纪录。有效动用川东地区石炭系数百亿立方米天然气低渗透储量、进一步提高石炭系单井产量是近年来四川油气田努力实现科学、高效开发的目标。板东006-H1井位于下川东地区典型的“三高”构造,井下情况异常复杂。为实现该井的安全、快速和高效钻进,
Recently, the Chongqing gas field of PetroChina Southwest Oil and Gas Field successfully injected large amount of acid into the east 006-H1 well of eastern Sichuan Carboniferous ultra-deep horizontal well plate at a temperature of 1 530 m3, The largest number of carboniferous horizontal section of the longest ultra-deep horizontal well naked eye segmented acidification records. The effective utilization of low permeable reserves of 10 billion cubic meters of carboniferous rocks in eastern Sichuan and the further improvement of single well production in the Carboniferous are the targets of efforts to achieve scientific and efficient development in Sichuan oil and gas fields in recent years. Well Dongdong 006-H1 is located in the typical “Three-high” structure in the area of Xiachuan East. The downhole situation is extremely complicated. In order to realize the well safety, fast and efficient drilling,
