萨喇杏油田老井压裂增油保持八年不降的实践与认识

PRACTICE AND COGNITION OF STABLE OIL PRODUCTION INCREMENT OF OLD-WELL FRACTURING FOR 8 YEARS RUNNING IN SALAXING OILFIELD

论述了萨喇杏油田老井压裂单井口增油9t八年（1987～1994年）不降所采取的技术措施，并对1995年及“九五”期间老井压裂增油的变化趋势进行了预测，提出了稳定压裂增油效果的有效措施。

This paper gives a discussion on technical measures adopted in Salaxing oil field,whose oil production increment of 9t per day for old-well fracturing keeps from dropping for 8 years (f rom l987 to1994),and forecasts the changing tendency of production gain of bld-well fracturing in 1995 and daring the Ninth Five-Year,and presents the effective measures to stabilize the oil production increment of old-well fractring
