Analysis of the exploitation potential of well DA1

Abstract

DA1 well exploited two sets of reservoirs, volcanic rock of Ying1 member and conglomerate of Ying4 member. In the initial stage of exploitation, the well had a high productivity. After an operation in 2010, the production situation of the well changed dramatically. In this paper, through the comparison of the production situation before and after the operation, the geological situation and the adjacent well, the operation pollution situation of the well is analyzed, and the exploitation potential of the well is analyzed, the measure scheme of plugging removal is put forward, and the stimulation prediction and economic benefit evaluation of the well are carried out, proving that the measure is effective and feasible.
