Well production characteristics and development technical measures in lacustrine carbonate reservoir of Subei Basin
摘要
Abstract
In western slope of Jinhu depression in Subei Basin, there is a set of lacustrine carbonate rocks that its oil storage ability is quite good. Because of the influence of nonuniform dissolution, the reservoir's plane heterogeneity is serious. Local area has much big-ger pores, but the pores' connectivity is poor. So, the permeability of the reservoir is low. Oil wells show completely different produc-tion characteristics from those wells which in sandstone reservoirs. In lacustrine carbonate reservoir, the wells' natural capacity is low and their productions have a large extent of improving after being acidified; the productions of wells in different locations are quite dif-ferent; the water cut is very high in initial production stage; and there are two forms of production decline: conventional decline and mu-tational decline. Based on the analysis of testing, production test information and production performance data, and further studying on the influence factors of production capacity, we summarize that the reservoir total effective thickness and reservoir effective seepage ra-dius of single well are two major factors for oil wells yielding, and further determine the screening conditions of reservoir which will put into production. According to lacustrine carbonate reservoir characteristics, the development technical measures of acidification, frac-turing, sidetracking well, horizontal well and multi-lateral horizontal well are accordingly proposed.关键词
