川中油气矿是西南油气田分公司唯一的具有采油条件的单位 ,所开采的裂缝型碳酸盐岩油藏占主导地位。因地层压力明显降低、排驱能力下降 ,致使单井原油产量相应下降 ,开采经济效益受到严重影响。针对低产特点 ,采用小泵抽 ;为了提高地层的排驱能力 ,采油泵入井深度加深 ,从而减?
The Central Sichuan Oil and Gas Mine is the only unit that has the conditions for oil production in the Southwest Oil and Gas Field Branch. The fractured carbonate reservoir dominates. Due to the obvious decrease of formation pressure and the decrease of drainage capacity, the output of single-well crude oil decreased correspondingly and the economic benefits of mining have been severely affected. For low-yield characteristics, the use of small pump pumping; in order to improve the formation discharge, deepening the depth of the oil pump into the well, thus reducing?
