剖189井区已进入生产开发末期,地层压力不断下降,油田能量供给不足,老井递减幅度大,找出油井高含水的原因已迫在眉睫。从油井的注水、生产曲线、井间连通状况、小层物性情况等方面来分析,找出油井高含水的原因,主要是井间的干扰。找出影响稳产的主要因素,这也为油区后续开发提供有力保障。
Section 189 well has entered the production and development of the end of the strata pressure continues to decline, inadequate energy supply to the field, the decline in the old well, find out the reasons for high water cut oil is imminent. From the well water injection, production curve, connectivity between wells, the situation of small physical properties and other aspects to find out the reasons for high water cut oil wells, mainly inter-well interference. Identify the main factors that affect stable production, which also provide strong protection for the follow-up development of the oil zone.
