介绍了一种安全且经济高效的多层产油井增产方法，该方法通过电缆将一种装有干化学药剂的工具部署到井下。在井下引发延长的放热反应，在射孔层段前方的目标深度产生酸化蒸汽，从而可以使用特定的酸化混合物对每个层段进行独特的处理。这种酸化方法因其持续的增产效果和成本效益而取代了之前的方法。
一家油田运营商的成熟产油井产量持续下降。该油井的典型特征是两个独特的层段：一个位于沃斯利白云岩层，另一个位于沃斯利粉砂岩层。
A safe and cost-effective method of stimulating a multizone hydrocarbon-producing well is presented wherein a tool containing dry chemical is deployed downhole by wireline. An extended exothermic reaction is initiated downhole that generates acid vapor at a target depth in front of the perforated interval, allowing each interval to be treated uniquely with specific acid blends. This method of acidizing has supplanted the previous method because of its sustained production enhancement and cost-effectiveness.
An operator’s field of mature oil-producing wells experienced steadily declining production. The typical well had two unique intervals, one being in the Worsley dolomite and the second in the Worsley siltstone.
