油井作业最佳时机分析

OPTIONAL TIME ANALYSIS OF OIL WELL OPERATION

油井从投入开发到关井的整个经济寿命期内 ,都遵循着产油量的逐渐递减和含水的不断上升 ,直到没有经济价值时为止。特别是进入开发中期以后 ,原油产量迅速递减 ,含水快速上升 ,为延缓产量的迅速递减和控制含水的快速上升 ,需要实施大量的增产措施。为了提高经济效益 ,也必须在油井的生产过程中适时的采取各种增产措施 ,来减缓产量的递减和控制含水的上升 ,从而来延长油井的经济寿命期。油田在开采过程中 ,随着时间的推移 ,单井产量逐渐下降 ,而成本不断上升 ,当油井的收益和成本相等时实施增产措施 。

Oil well always follows the production rate decreasing and the containing water increasing from the beginning of the development to the well closed not until it is no economic value. Especially, it is developed after the middle development term, the crude oil production rate was declined quickly and the contained water was raised quickly. The measurement of the increased production was necessary for the production decrement to be delayed and the contained water increment to be controlled, it will enhance the life of the oil well economy. The cost will gradually be increased when the oil well is production with the time lose. It will make the economic benefit maximum in the whole oil well life when the oil well benefit was equal to the cost by some measurements.
